Chickpea is highly sensitive crop to weed competition as early stage of growth. A field experiment was conducted during winter season of 2013-14 to 2015-16to know the response of application of sequential application of herbicides under different sowing methods. Results revealed that chickpea sowing in reduced tillage performed better and produced higher number of pods per plant, seed yield and protein yield over conventional tillage. In weed management treatment, sequential application of [email protected] kg a.i./ha pre-em followed by imezethapyr @40 g a.i./ha post-em improve the crop growth and produced higher seed yield (1515 kg/ha) and protein yield. Total weed density and weed dry weight were recorded minimum under reduced tillage at both 30 and 60 days after sowing. Application of pendimethalin @0.75 kg a.i./ha pre-emfollowed by imezethapyr @40 g a.i./ha post-em reduced the total weed density and weed dry weight over other treatments and recorded minimum. Weed control efficiency recorded higher with conventional tillage (70.04%) and closely followed by reduced tillage (70.81%). [email protected] a.i./ha pre-emfbimazethapyr @ 40 g a.i./ha recorded highest weed control efficiency (92.93%) followed by pendimethalin 0.75 kg a.i./ha fbquizalofop ethyl 50 g a.i./ha (85.41%) and pendimethalin 1.0 kg a.i./ha (73.78).

In Haryana (India) cotton is generally sown with conventional tillage practices witnesses poor germination and plant establishment. Poor plant stand is attributed by burning of emerging plants due to very high temperature at the time of planting, which is further worsen by crust formation due to pre-monsoon showers. Keeping these points in view, an experiment was conducted with farmers' participatory research mode in village Hajwana of Kaithal district. Cotton sown with zero tillage technique resulted in approximately five percent higher yield i.e. 136.3 kg ha-1 over conventional tillage. Mean returns over variable cost of all the three years were 10.8 percent i.e. Rs. 11794 ha-1 more in zero tillage over conventional tillage. Benefit: cost ratio were 3.86, 3.86 and 4.61 in conventional method of planting, bed planting and zero tillage technique, respectively. Zero tillage planting of cotton reduced fuel consumption by 93.4 % and 91.7 % compared to bed planting and conventional planting respectively.

Dry direct-seeded rice has been shown to save irrigation water and labor. Nonetheless, irrigation management in dry direct-seeded rice has received very little attention. Here, we examined the potential of different irrigation regimes: aerobic rice (AR), alternate wetting and drying (AWD) and continuous flooding (CF) in dry direct-seeded rice cultivation on two rice cultivars (Pride-1 (hybrid indica) and NB-1 (inbred indica)). Growth, yield attributes, grain yield, total water input, water productivity and benefit cost ratio were measured. Our results showed that AR saved 11.22 and 28.40%, and 5.72 and 32.98% water compared with AWD and CF during 2018 and 2020, respectively. There was a significant difference in grain yield among treatments and cultivars. AWD and CF produced statistically same total dry weight and grain yield, while AR reduced the total dry weight by 31.34% and 38.04% and grain yield by 34.82% and 38.16% in comparison to AWD and CF, respectively, across the years. Except for 1000-grain weight and harvest index in AWD and CF, further differences in total dry weight and grain yield among irrigation treatments were primarily correlated with variations in yield attributes. Among the cultivars, hybrid rice performed better than inbred rice. Over the two-year period, hybrid rice increased total dry weight, grain yield, and water productivity by 9.28%, 13.05%, and 14.28%, respectively, as compared to inbred rice. Regarding water productivity (WP), the maximum percentage (40.90 and 26.53%) was recorded for AWD compared to AR and CF. Among cultivars, more water productivity (14.28%) was calculated for hybrid rice than inbred one. Chlorophyll and carotenoid contents, leaf area index and crop growth rate contributed to higher grain yield of hybrid rice under AWD and CF. In contrast to WP, the maximum benefit cost ratio was estimated to be higher for CF than that of AR and AWD. For the cultivars, the maximum value (2.26 in 2018 and 2.32 in 2020) was calculated for hybrid rice compared with the inbred one. In conclusion, these results suggests that AWD with maximum WP and CF with maximum BCR could be more efficient approaches than AR. Under CF, hybrid rice cultivars with higher yield and yield-related attributes, WP and BCR performed better.

Field experiments were conducted during summer (April to June), 2010 and 2011 to study the effect of post-emergence herbicides in irrigated blackgram (ADT 5). Treatments comprising of three levels (50, 75 and 100 g /ha) of the post- emergence herbicides viz., Imazethapyr 10% SL and Quizalofop ethyl 5% EC were tested alone and in combination and compared with hand weeding twice on 15 and 30 DAS(farmers’ practice). Herbicides were sprayed on 15 DAS when the weeds were 2-4 leaves stage using flat-fan nozzle as per treatment schedule. The results revealed that minimum total weed density (8.44) and weed dry weight ( 27.2 g/m2) and higher weed control efficiency (84.4%) were obtained under combined application of imazethapyr and quizalofop ethyl as tank mix at 100 g /ha. However, this was comparable with application of both the herbicides at 75g /ha. Application of imazethapyr + quizalofop ethyl each at 75 g/ha registered significantly taller plants, higher dry matter production, more number of pods per plant, seeds per pod and higher grain yield (826 kg/ha), net returns (Rs.26621/ha) and benefit cost ratio (2.76). Thus, application of post- emergence herbicides imazethapyr + quizalofop ethyl each at 75 g /ha as tank mix on 15 DAS could be recommended for controlling of emerged weeds in irrigated blackgram.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

An experiment was conducted with the objective of ascertaining the feasibility of cultivation of pigeonpea during rabi season in the alfisols of Southern Telangana Zone. Further, it was designed to understand the performance of pigeonpea genotypes at various plant densities and also the economics of pigeonpea cultivation during rabi season. It consisted of 12 treatments with four plant densities in main plots and three genotypes in sub plots in split plot design. The pooled data of 2015-16 and 2016-17 revealed that significantly higher seed yield (1532 kg ha-1) was recorded at plant density of 60 cm × 10 cm spacing than at 45cm × 10cm (1332 kg/ha), 75 cm × 10 cm (1321 kg/ha) and 90 cm × 10 cm (1141 kg/ha). Among the genotypes, the seed yield in PRG-158 (1547 kg/ha) and Asha (ICPL 87119) (1591 kg/ha) was on par with each other but significantly higher than in PRG-176 (857 kg/ha). The higher gross returns (Rs. 77366 ha-1), net returns (Rs.46733 ha-1) and benefit cost ratio (2.53) was recorded at plant density of 60 cm × 10 cm spacing than at other tested plant densities (45 cm × 10 cm, 75 cm × 10 cm and 90 cm × 10 cm). Among the genotypes, Asha (ICPL 87119) registered highest gross returns (Rs. 80346 ha-1), net returns (Rs.49711 ha-1) and benefit cost ratio (2.62) followed by PRG-158 (gross returns of Rs. 78124ha-1, net returns of Rs.47489 ha-1 and benefit cost ratio of 2.55) and PRG-176 (gross returns of Rs. 43279ha-1, net returns of Rs.13144 ha-1 and benefit cost ratio of 1.44). Thus, the spacing of 60 cm × 10 cm is recommended for the cultivation of pigeonpea during rabi season in alfisols of Southern Telangana Zone with long duration varieties like PRG-158 and Asha (ICPL-87119).

On-farm research was conducted at Gouripur sub-district under Mymensingh district of Bangladesh during the boro (mid November-June) season in 2013-14 and 2014-15 to evaluate the performance of non-puddled rice cultivation with and without crop residue retention. The rice var. BRRI dhan28 was transplanted by two tillage practices viz., puddled conventional tillage (CT) and non-puddled strip tillage (ST) and at two levels of mustard residues, i.e., no residue (R0) and 50% residue (R50). The experiment was designed in a randomized complete block design with four replications. There were no significant yield differences between tillage practices and residue levels in 2013-14. But in the following year, ST yielded 9% more grain compared to CT leading to 22% higher BCR. Retention of 50% residue increased yield by 3% compared to no-residue, which contributed to 10% higher benefit-cost ratio (BCR). The ST combined with 50% residue retention yielded the highest grain yield (5.81 t ha-1) which contributed to produce the highest BCR (1.06).

An experiment was carried out during thekharif season of two consecutive years 2014 and 2015 at Regional Research Sub-station, Raghunathpur, Bidhan Chandra Krishi Viswavidyalaya, Purulia, West Bengal with the view to maximise the jute seed yield by manipulating certain non-monetary techniques like dates of sowing and topping associated with crop production. The Capsularis variety Bidhan pat-3 was sown in three different dates (1st-25th June, 2nd-15th July and 3rd-5th August) with 3 topping (clipping of apical portion) practices at 30, 45 and 60 days after sowing (DAS) as separate treatment with no topping as control. These different agronomic practices significantly (at 5 % probability level) influenced the performance of the crop in various aspects. The 1st date of sowing showed its supremacy in terms of expression of the crop in the field in all the aspects achieving a seed yield of 709.50 kg ha-1 and 737.85 kg ha-1 during first and second year respectively, whereas, the last date of sowing showed its inferiority obtaining a seed yield of 590.10 kg ha-1 and 647.13 kg ha-1all through the first and second year respectively.1stdate of sowing also recorded higher net return(Rs. 33721.50 ha-1& Rs.35989.50 ha-1 during first and second year) and benefit: cost ratio (1.46 and 1.56 in first and second year) over the other two date of sowing. How-ever, maximum seed yield was achieved when the crop was topped on 45 DAS (728.80 kg ha-1 and 773.57 kg ha-1 during first and second year) irrespective of the date of sowing.
