Recent Research Thrust Addressing Climate Change and how far Agronomists can do?
Recent Research Thrust Addressing Climate Change and how far Agronomists can do?
Agronomy Division, Regional Agricultural Research Station
Introduction
Agronomists are working to meet the challenges of food and nutritional security of the country. Now, it is imperative to change traditional agronomic research and new domain of agronomic research is to be addressed as the changing climate. However, they are devoted to develop demand based technology for sustainable crop production. They are trying to provide solutions of the problems at changing climatic conditions. Consequently, recent agronomic research has addressed new domain and succeeded to some extent.
New research domain and success
1. Screening and adaptation of crop varieties/lines and development of sustainable production technology for costal area.
BRRI Dhan 47 is a salinity tolerant rice variety recommended for boro season. It can tolerant salinity level up to 8 dS/m (Abedin, 2010). Mungbean line (BM-1), barley line (BHL-15), soybean (Shohag and BARI Soybean 5) were found moderately salt tolerant (up to 8 dS/m) (Aziz, 2010a). The potato lines, 86-140 (18.33 t/ha) & 88-163 (18.06 t/ha) and the varieties, Heera (18.61 t/ha), Chamok (18.33 t/ha), Multa (18.06 t/ha), Colombus (18.06 t/ha), Sirinda (19.17 t/ha) & TPS-1 (18.61 t/ha) can be grown suitably at costal area (salinity level from 3.31 to 6.14 m mhos/cm from November to March) (Mian et al. 2005). Green manuring, use of organic materials, ridge-bed planting, mulching, deep ploughing etc. are the agronomic options for management of salinity. Gypsum and silicon application can ameliorate salinity stress in rice and other crops (Kader and Islam, 2010). Salt tolerant crops like cowpea, maize, barley, soybean, sweet potato, sweet gourd etc. should be grown at costal area.
2. Screening of different crop genotypes for drought tolerance and development of technology for drought management.
Mungbean line (BMX 90009-6, BMX 01015 and BMX 01007) (Mian et al. 2010a) and wheat line (BAW 923, BAW 923-4, BAW 923/ BAW 824 and BAW 1138) (Aziz, 2010b) showed moderately drought tolerance. Organic matter, green manuring, mulching, dense plant population, weeds as smothering where the growth of weed is minimum, supplemental irrigation from harvested rain (if possible) etc. are to be used for drought management. Drought tolerant crops like maize, barley, sweet potato, sesame, sorghum, millet, pigeon pea, groundnut should be chosen for drought prone areas.
3. Screening of different crop genotypes for heat tolerance and adjustment of sowing/planting time for avoidance heat stress.
Some wheat varieties (BARI Gom 20, BARI Gom 24, BARI Gom 25 and BARI Gom 26) proved to be moderately tolerant to high temperature (Aziz, 2010b ; Mian and Islam, 2010b). BARI Seam 3, BARI Tomato 3, BARI Tomato 4,
4. Screening of different crop genotypes for excess soil moisture or water logging tolerance and development of management options for excess soil moisture.
Sesame line (BD 6980, BD 6985, BD 6992 and BD 7010) were identified as water logging tolerant at vegetative stage (Saha, 2010). Mungbean genotype (VC 3960-88 and BARI Mung 4) had tolerance ability of flooding at 21 days old seedling (Pervin et al., 2010).
5. Development of charland through adaptation of improved crop varieties and production technologies.
About 0.83 million ha charland are available in the country (Aziz, 2009). BARI Chola 4, BARI Soybean 5, BARI Mung 6, BARI Til 4, BARI Sarisha 11 and BARI Sarisha 14, BARI Hybrid maize 7 and
6. Improvement of cropping system of hilly areas.
After harvest of T.aman rice BARI Sarisha11, BARI Hybrid Maize 5, BARI Chola 5, BARI Mosur 4, Shatabdi, Sourav and Bijoy of wheat, BARI Hybrid Maize 5 + Bushbean and BARI Hybrid Maize 5 + BARI Falon 1 intercropping were found suitable for increasing production and cropping intensity in hilly areas (Aziz, 2010c). BARI Mung 5 performed better after harvest of mustard against T.aman –fallow-fallow pattern (Aziz, 2010c). More attention is needed for adoption of improved crop varieties and cropping system at hilly areas.
7. Improvement of cropping system of haor areas.
In coordinated research of CNRS (Centre for Natural Resources study) revealed that two crops could be grown in haor areas. BARI Sarisha 11, BARI Sarisha 14, BARI Gom 22, BARI Gom 23, BARI Gom 24, BAR Motorshuti 2, BARI Mung 5, BARI Mung 6 performed better in haor areas (Aziz, 2010b).
8. Adaptation of submerse rice variety at flood prone areas.
Submergence tolerant gene SUB1 is identified and transferred to 5 mega rice varieties i.e. Swarna, samba mahsuri, IR 64, CR 1009 and BR 11. These 5 mega varieties are widely cultivated by the farmers because of their high yield and good grain quality. However, these varieties were susceptible to flash flood and they could not tolerate more than 4 days of submergence. Now, these SUB 1 gene varieties can tolerate submergence 14-17 days (Singh et al., 2010). IR 64 sub1, Sarna sub1 and Samba sub1 showed submergence tolerant in North-western region of
9. Development of technology for cyclone prone areas.
The maize variety Pacific 11, Pacific 984 and BARI Hybrid maize 5 were found suitable for cultivation in costal cyclone prone area after harvest of T.aman rice (Aziz, 2010a and Mian, 2008). More research is needed for adaptation of improved production technologies at cyclone prone areas.
10. Development of agro-climatological model for crop yield at changing climate.
“Enso effect on rice production in
Conclusion
The Agronomists should give research thrust in aforesaid new domain of agronomic research more effectively than at present cope with changing climate. So, they should acquire sufficient knowledge about the relevant field of research for better contribution for the nation. They need capacity building through advanced agronomic research regarding climate change. They should have sufficient physical facility and financial support for need based research for solving the present problems. Our government and relevant authority should have consider the matter very seriously.

Abstract of Ph.D. Thesis of Dr. Md. Abul Khayer Mian
Four experiments were carried out at the Regional Agricultural Research Station, Bangladesh Agricultural Research Institute, Jessore in two consecutive years of 2004-2005 and 2005-2006 to evaluate the agro-economic performance of several maize oriented cropping patterns under different nutrient management. Maize-Mungbean (green manurng, GM)-T.aman rice was found to be the best cropping pattern under high nutrient level of 266-46-132-28-2.10-0.60 kg ha-1 of N-P-K-S-Zn-B for maize and 100-13-43-6.0-0.70 kg ha-1 of N-P-K-S-Zn for rice and moderate nutrient level of 186-34-95-20-1.60-0.60 kg ha-1 of N-P-K-S-Zn-B for maize and 74-11-33-4.5-0.40 kg ha-1 of N-P-K-S-Zn for rice showing better growth behaviour, yield performance, productivity, land use efficiency, production efficiency and profitability as compared to the existing cropping pattern of Wheat-Fallow-T.aman rice. This pattern rendered 89% higher maize equivalent yield (MEY) than the existing pattern. Furthermore, Maize-Dhaincha (GM)-T.aman rice and Maize-Soybean (GM)-T.aman rice proved to be better cropping patterns in respect of the aforesaid parameters under high and moderate nutrient levels. Maize-Mungbean (GM)-T.aman rice, Maize-Dhaincha (GM)-T.aman rice and Maize-soybean (GM)-T.aman rice patterns produced higher grain yield of maize (9.91-10.39 t ha-1 ) and rice (5.22-5.90 t ha-1) in high nutrient level due to improvement of yield components. Inclusion of mungbean (GM i.e. brown manuring) in the sequence provided an extra remuneration with seed yield of 530-1056 kg ha-1. Maize+ Sweet potato, Maize+ Soybean and Maize+ Cowpea were found to be suitable intercropping representing higher productivity (10.92-11.99 t ha-1 of MEY) and monetary advantage in high and moderate nutrient levels. Maize showed better yield performance (9.07-10.34 t ha-1) in intercropping with legumes (soybean, blackgram and cowpea). Maize+ Sweet potato-Mungbean (GM)-T.aman rice, Maize+ Soybean-Mungbean (GM)-T.aman rice and Maize+ Sweet potato-Dhaincha (GM)-T.aman rice under high nutrient level and Maize+ Sweet potato-Mungbean (GM)-T.aman rice under moderate nutrient level emerged as further improvement of Maize-Mungbean (GM)-T.aman rice cropping pattern. There existed better relationship of grain yields with growth parameters and yield components of maize and rice in maize oriented cropping patterns and intercropping under different nutrient levels. Dry matter partitioning into reproductive organ at later growth stages was higher in higher nutrient levels contributing to increased grain yield of maize and rice. Grain yield as well as system yield response to nutrients applied in maize and rice were significant representing variable coefficient of determination. Contributions from GM in the sequence and incorporation of legume residues from intercropping towards nutrient balance in the soil were found to be positive. Balance of P and S was more favourable than that of N, K and Zn in the soil. Inclusion of GM or incorporation of legume residues in the system improved organic matter content of the soil. Nutrient returned to soil from GM or legume residues was correlated with the nutrient balance in soil indicating improvement of soil health. Among the GM crops, mungbean ranked first in respect of nutrient concentration in plant tissue and nutrients returned to soil. It is concluded that Maize-Mungbean (GM)-T.aman rice or Maize+ Intercrops (sweet potato or soybean)-Mungbean (GM)-T.aman rice cropping patterns would be more productive and profitable technology for future crop production in Bangladesh.

Dr. M.A.K Mian is with his collegues of BARI in a papaya field.
Papaya is a very good friut. It also can be used as vegetable. It contains Vitamin A in rippening condition. It contains Pepsin enzyme which is very important for human digestion. Papaya is used as liver tonic. It is usefull to remove constipation of man. It is a proverb that take a papaya everday and keeps the doctors away. A papaya plant can bears about 10-20 papaya or more in a seasons or year. A farmer can get Tk. 600.00/(20x30=600.00) per plant in annum easily. Two-three plants of a famer house can fullfil the demands of the family. Moreober, he can sell some portion and can earns money. There needs no more management in papaya. Fafmers can grow 4-5 plants easily at the sourrounding of the house. Boron deficiency sometimes desafed the fruits and leaves and also the stem. So the farmers should add 1-2 g boric acid per adult plant. The news will be broadcast through BTV channel of National Assembly at off time.

Agronomy Division, Regional Agricultural Research Station, BARI, Jessore-7400, Bangladesh.
A field experiment was conducted at the Regional Agricultural Research Station, Ishurdi during February to July of 1996 to observe the critical period of weed competition on yield of groundnut. Groundnut variety “DM-1” was tested in a RCB design with three replications. The 11 weeding treatments were: continuous weed free, weed free upto 15 DAE, upto 30 DAE, upto 45 DAE, upto 60 DAE, weed free after 15 DAE, after 30 DAE, after 45 DAE, after 60 DAE, no weeding and earthing up only. The crop was sown in flat method at 25 cm × 15 cm spacing on 19 February. Nutrients @ 50-90-40-20-4 kg/ha of N-P2O5-K2O-S-Zn were applied. Weeding was done by indigenous hand weeding just after collecting the weed samples by quadrate method. Dry matter weight of weed and yield of groundnut was recorded. The results indicated that critical period of weed competition was 15 DAE to 45 DAE in groundnut in the early kharif season. The yield loss due to weed competition was about 89%.

Two field experiments were conducted an Saroil, Farming System Research (FSR) site of Bangladesh Agricultural Research Institute in Barind Trace to observe the performance of chickpea under different management practices. In one experiment, five planting methods for chickpea were broadcast (T1), line sowing (T2), dibbling (T3), dibbling and mulching (T4) and line sowing and mulching (T5). The experiment was laid out in a RCB design with four replications and plot size of 5 m × 4 m. Among the above treatments, T5 produced the highest seed yield (1398 kg/ha) which was closely related to T2 (1365 kg/ha). These two treatments also rendered the maximum dry matter weight of chickpea. In another experiment, three soil moisture regime viz. no irrigation (I0), irrigation at 80% depletion of available soil moisture (ASM) (I1) and irrigation at 60% depletion of ASM (I2) were studied for chickpea. The experiment was laid out in a split plot design with four replications and plot size of 5 m × 4 m. The treatment, I2 gave the highest seed yield (1623 Kg/ha) contributed by the highest yield components. Similar trend of yield and yield components was followed by the treatment I1 where I1 and I2 were identical.

A screening trial of mungbean varieties/lines for drought tolerance was conducted at Regional Agricultural Research Station, Ishurdi, Pabna. Eighteen varieties/lines were screened in pot culture under controlled condition. The rainfall was controlled by polythene tunnel. Pots were filled with soil and manure mixture including fertilizers. Sowing was done on 8 April 2009. Five mungbean seeds of each varieties/lines were placed in the individual pot with three replications. The pots were watered for ensuring germination of seeds. After germination, no water was applied. Pots were kept weed fiee till harvest. Total dry matter (TDM) of mungbean and soil moisture was recorded at 35 days after sowing. Soil moisture level ranged from 6.21-9.03% among the pots. Collected TDM of mungbean was subjected to statistical analyses. The TDM showed significant variation among the varieties/lines. BMX 01008, BMX 01013, BMX 01014 and BMX 01015 showed more tolerant (TDM of 0.390-0.420 g/plant) to drought and BARI mung 3, BU mung 1, BU mung 4, BINA mung 5 and BMX 01007 showed moderately tolerant (TDM of 0.247-0.337 g/plant) on the basis of dry matter production and physical field observation. BARI mung 5 and BARI mung 6 produced the lowest TDM yield.

Annual Botanical Conference 2009 of Bangladesh Botanical Society (Janury 9-10):37
RARS Ishurdi and Dept. of Agromony, Bangladesh Agricultural University
An ecological study of weed was undertaken to know the type of weed species as well as nature of weed vegetation in T.aman rice ecosystem as affected by cultivars and also to observe the relationship between weed growth and grain yield of rice. The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University. Mymensingh. Four cultivars viz. BR 11, BR 22, Nizersail and Biroi were taken into the investigation under RCB design with four replications. Weed samples were collected at 20 and 55 days after transplanting by quadrat (1.00 m × 1.00 m) method. Eight weed species belonging to six families were observed in the experimental plots. Grass type included the Paspalum scrobiculatum L. and Echinochloa colonum L. of Gramineae whereas sedge included Fimbristylis littoralis (L.) Vahl. and Cyperus iria L. of Cyperaceae. The broadleaf type comprised with Alisma plantago L., Jussieua decurrens (Walt.) DC., Polygomm orientale L. and Sphenoclea zeylaica Gaertn. of the family Alismacae, Onagraceae, Polygonaceae and Sphenocleaceae respectively. Among them, Paspalum scrobiculatum L. was the most dominating species in respect of summed dominance ratio (SDR of 41.71) and relative dry weight (RDW of 60.18%). All weed species except A. plantago L. and J. decurrens (walt.) DC were found dominant in semi-dwarf modern cultivars (BR 11 and BR 22) than in traditional tall cultivars (Nizersail and Biroi). The highest co-efficient of similarity was rendered by BR 11 versus BR 22 (91.22%), similarly by Nizersail versus Biroi (90.22%). All the cultivars demonstrated a positive relationship (r= 0.71 at p<0.01)between>

A field trial was conducted with three varieties of sesame and six dates of planting at Ishurdi. Yield and yield attributes were significantly affected by sowing dates and cultivars. Significantly the highest seed yield (1130 kg/ha) was obtained from 15 March sowing due to higher number of pods per plant, seeds per pod and individual seed weight which was identical to 1 March sowing (1095 kg/ha). Among the cultivars, T-6 produced highest yield (1140 kg/ha) but it did not differ significantly form that of Jamalpur. Compared to the sowing date of 15 March, other dates of sowing reduced yield by 0.03 to 85.86%. The first fortnight of March was found to be the optimum time of sowing. The cultivar T-6 performed best followed by Jamalpur.

The experiment was conducted to find out the effect of row orientation (E-W, N-S and bidirection) and weed control methods (hand, mechanical, pre and post emergence weedicide and control) on weed growth, yield and economics of mustard at Regional Agricultural Research Station, Jessore for two consecutive growing seasons 1997-98 and 1998-99. Among the major identified weed species, Cyperus rotundus L. was the most dominant one (79%). Dry matter of weed was found minimum (63 g/m2 at 20 DAE and 61 g/m2 at harvest) in bidirection and maximum (72 g/m2 at 20 DAE and 88 g/m2 at harvest) in north-south row direction. Per-emergence “Ronstar” (@ 2 L/ha) application rendered less (35 g/m2) weed growth at early growth stage i.e. 20 DAE) and hand weeding at 20 DAE gave minimum (27 g/m2) weed growth at later growth stage (i.e. harvest) of the crop. North-south row direction gave significantly highest yield 1286 kg/ha) than other two directions. Hand weeding at 20 DAE, mechanical weeding by BARI-weeder at 20 DAE and pre-emergence “Ronstar” application produced 21% and 18% higher yield over control treatment. These three weed control methods gave the highest yield (1428, 1402 and 1397 kg/ha) in north-south row direction compared to other treatment combinations. But from economic point of view, mechanical weeding by BARI-weeder at 20 DAE and per-emergence “Ronstar” application in north-south row direction were found superior in respect of higher net return (Tk 13543 and 13438/ha) and BCR of 2.16 and 2.15, respectively.

An investigation was carried out to assess the effect of type plough and number of ploughing on weed infestation and performance of mustard (Brassica campestris) in Calcareous Gray Floodplain soil of Bangladesh at Regional Agricultural Research Station, Ishurdi for 2 consecutive seasons of 1995-96 and 1996-97. BARI plough with 6 ploughing rendered less weed infestation (393.0 m-2) and produced maximum weed dry weight (99.7 g m-2). BARI plough produced 15% more yield over country plough while the highest yield was observed in 6 ploughing. BARI plough was found superior at 4 ploughing in respect of higher gross margin (Tk 8431/ha) and benefit cost ratio (1.97).

A field experiment was conducted to find out a suitable dose of fertilizer for hybrid maize (var. Pacific 11) intercropping with soybean (var. Sohag), two planting system and four fertilizer levels were used as treatment variables. Highest grain yield of maize was obtained from the highest does of fertilizer. But soybean yield was the highest in lower doses of fertilizer at Jessore and Hathazari but at Joydebpur 250-120-120-40-5 of N, P2O5, K2O, S, Zn Kg ha-1. Yield attributes increased with the increase of fertilizer in case of maize but reverse in soybean. From economic point of view, the highest benefit cost ratio was obtained from the fertilizer dose 250-120-120-40-5 of N, P2O5, K2O, S, Zn Kg ha-1 in both normal and paired row systems at Joydebpur of Bangladesh. But at Jessore and Hathazari fertilizer dose 200-80-80-20-5 of N, P2O5, K2O, S, Zn Kg ha-1 was found profitable.

Healthy, PLRV and PVY infected second generation seed tubvers of four potato varieties, namely Ailsa, Binella, Cardinal and Diamant were planted in the field. Under natural conditions, appearance of visible symptoms of PLRV and PVY infection was significantly delayed in all the varieties. Both the viruses caused significant reduction in plant height, number of fubers per plant, tuber size and yield per plant over control (healthy seed). The reduction in plant growth, tuber yield and tuber size was significantly higher due to PVY infected seed tubers as compared to PLRV infected seeds. The percentage of marketable size tubers (28-55 mm) was maximum in healthy seed tubers which was followed by PLRV and PVY infected seeds.

Field experiments with three mungbean cultivars viz. BARI mung-2, BARI Mung-3 and BARI Mung-4 under four times of sowing i.e. 15, 30 August 15, 30 September were conducted at the Regional Agricultural Research Station (RARS), Jessore during 1998 and 1999. 30 August sowing of BARI Mung-3 and BARI Mung-4 recorded better plant growth indicating better dry matter production. The same treatments also produced the superior seed yield (1538 and 1409 kg/ha, respectively) contributed by higher number of branches per plant (4.77 and 4.70, respectively), number of pods per plant (27.41 and 26.63, respectively) and 1000-seed weight (43.06 and 43.39 g, respectively).

Field experiments were conducted in the Farming System Research site of Bangladesh Agricultural Resarch Institute in Barind Tract at Saroil, to study responses of chickpea to different levels of field management. In one experiment, five planting methods, viz. broadcasting, line sowing, dibbling, dibbling followed by mulching, mulching and line sowing followed by mulching; and in another experiment, three soil moisture regimes, viz. no irrigation, irrigation at 80% depletion of available soil moisture (ASM) and irrigation at 60% depletion of ASM were studied for chickpea cultivation. Line sowing followed by mulching produced the highest seed yield (1398 kg/ha) followed by line sowing (1365 kg/ha) and dibbling followed by mulching (1302 kg/ha). These three treatments produced maximum dry matter weight per plant. Line sown crop performed better than broadcast crop. Irrigation at 60% depletion of ASM gave the highest seed yield (1623 kg/ha) followed by irrigation at 80% depletion of ASM. The highest seed yield was associated with the production of greater yield components.

A field experiment was conducted during March-July of 2002 and 2003 at the Regional Agricultural Research Station, Jessore to evaluate the efficacy of herbicides in controlling weeds in maize (cv. Barnali). Treatments consisted of pre-emergence application of U-46, Ronstar, Round up, Raphit and post-emergence application of U-46, Ronstar, Round up and Rephit herbicides. These treatments were compared with the weedy check (no weeding), weeded by hand at 25 and 45 DAE and weeded by BARI weeder at 25 plus one hand weeding at 45 DAE. Among the weed species, Cyperus rotundus L. was found dominant in respect of absolute density, relative density and infestation of weed followed by Cynodon dactylon (L.) Pers, in both the years. Pre-emergence application of U-46 herbicide effectively controlled the weed population and dry weight compared with the unweeded (control) and also other weed control treatments. Weed free treatment generally increased yield components and yield of maize. The plots weeded by hand at 25 and 45 DAE gave higher yield but it was identical with that of the plots weeded by pre-emergence application of U-46. Among the weed control methods tried, U-46 at pre-emergence application had a pronounced effect on gross margin and benefit cost ratio followed by two hand weedings at 25 and 45 DAE.

An experiment was conducted to know the effect of three population densities (66667, 88889 and 133333 plants ha-1 corresponding to 60 cm ´ 25 cm, 45 cm ´ 25 cm and 30 cm ´ 25 cm spacing, respectively) and four N levels (150, 200, 250 and 300 kg ha-1) on sweet corn (cv. 141 BRIXL-10) at the Regional Agricultural Research Station, Jessore during two consecutive rabi (winter) seasons of 2002-2003 and 2003-2004. The results revealed that green cob yield and yield attributes were significantly influenced by the variations of population density and N level. The plant density of 88889 plants ha-1 (45 cm ´ 25cm) recorded significantly higher green cob yield than lower (66667 plants ha-1) and higher 133333 plants ha-1) plant densities in both the years. Significant response to N application was noticed up to 250 kg ha-1. Plant density 88889 ha-1 or spacing of 45 cm ´ 25 cm coupled with 250 kg N ha-1 was optimum for sweet corn variety 141 BARIXL-10 for higher yield during rabi season.

An experiment on maize/spinach-red amaranth intercropping was conducted to find out suitable planting system in two successive rabi seasons (2002-2004) where spinach and red amaranth were intercropped one after another with normal and paired row planted maize. Sole plots yield was higher than that of intercrop plots. Although intercropping system reduced maize yield by 4 to 19% in different treatments but total productivity and profitability was increased with an additional yield of spinch (2.84 to 7.08 t/ha) and red amaranth (1.05 to 2.33 t/ha). Intercropping system also increased land equivalent ratio (LER), maize equivalent yield (MEY) and monetary advantage. The highest LER (1.99), MEY (17 t/ha), gross return (129075 Tk/ha), net return (100181 Tk/ha) and benefit cost ratio (4.47) was obtained where 3 rows spinach followed by red amaranth was intercropped with normal row maize. All the intercropping system showed higher BCR than sole maize.

The experiment was done at the farmers field of Kashimpur, Gazipur during winter season, 1998-2001, to find out the most effective weed control method for cabbage cultivation. Weeds were controlled by (i) hand weeding at 15 days after transplanting (DAT) (ii) hand weeding at 15 DAT + 35 DAT (iii) weeding by BARI weeder at 15 DAT + hand weeding at 35 DAT (iv) farmers practice (v) continuous weed free and compared with (vi) no weeding (control). Results revealed that weed population and growth were minimum in weed free, farmer’s practice, two hand weeding and BARI weeder + one hand weeding treatments. Consequently yield, yield attributes and economic performance was better in these weed control treatments. Higher yield of cabbage 56-61 t ha-1 was observed in weed free, farmer’s practice, two hand weeding and BARI weeder + one hand weeding treatments. Co-relation trend indicated that yield of cabbage was negatively correlated with weed growth ( r=-0.76 at p=0.01). However, about 46% yield loss was estimated due to weed competition in cabbage. Thus two hand weeding at 15 DAT and 35 DAT or BARI weeder at 15 DAT + one hand weeding at 35 DAT or farmers practice (4 weeding) was most as suitable weed control method for cabbage cultivation.
