A field experiment conducted at Jammu (Jammu and Kashmir) during summer season of 2013 to study the influence of sowing dates and varieties on the yield, heat use efficiency, helio-thermal use efficiency, energy utilization efficiencies and economics of summer mungbean. The experiment was conducted in a split plot design consisting of four sowing dates (20th March, 5th April, 20th April and 5th May) as main-plot treatments and four varieties (SML 668, Samrat, Meha and IPM 02-3) as sub–plot treatments. Higher grain yield (9.33 q ha-1) of summer mungbean was recorded under 20th March sowing date, which was statistically at par with 5th April sowing but significantly higher than 20th April and 5th May sowing. Among the varieties, Samrat produced significantly higher grain yield (7.82 q ha-1) than all other varieties except SML 668. But, the heat use efficiency (HUE), helio-thermal use efficiency (HTUE) and energy pattern was significantly higher at 20th March than other dates of sowing. The varieties Samrat and SML 668 recorded significantly higher HUE, HTUE and energy pattern than IPM 02-3 and Meha. The highest benefit cost ratio (1.42) was recorded with 5th April sowing date closely followed by 20th March (1.39). The variety Samrat also registered the highest benefit cost ratio (1.07) followed by SML-668.

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.

The experiment was conducted at Multi Location Testing (MLT) site, Moulvibazar, Bangladesh during rabi season of 2016-17 and 2017-18 to study the profitability of intercropping of hybrid maize with vegetables and spices. Five intercrop combinations of hybrid maize along with sole maize were arranged in randomized complete block design (RCBD) replicated six times. There were six treatments viz., T1: Maize + potato, T2: Maize + red amaranth, T3: Maize + spinach, T4: Maize+ data shak, T5: Maize + coriander and T6: Maize as sole. The grain yield of maize in intercropped combination varied significantly. The highest grain yield (9.71 t ha-1) was in sole maize. The highest maize equivalent yield 15.60 t ha-1 was recorded from the treatment T1 (100% maize + potato) whereas the lowest yield (8.61 t ha-1) was obtained from the treatment T6 (sole maize). The highest gross return (Tk. 312000 ha-1) and benefit cost ratio (3.29) was obtained from the treatment T1 (100% maize + potato). On the contrary, the lowest gross margin (Tk. 101600 ha-1) was obtained from treatment T2 (maize + red amaranth). It revealed that the combination of maize with potato was more compatible and profitable intercropping system in Sylhet region of Bangladesh Bangladesh Agron. J. 2018, 21(2): 73-78

The study was conducted to determine the productivity, profitability and resource use efficiency of maize-pumpkin mix crop production in Chitwan. The study used 53 maize-pumpkin mix crop adopting farmers from among 300 farmers adopting different pollinator friendly practices. Descriptive and statistical tools including Cobb-Douglas production function were used to analyze data, collected from structured interview schedule. The benefit cost ratio (1.58) indicates that maize-pumpkin mix cropping was profitable with productivity of 2.83 ton per ha on maize main product equivalent basis. The magnitude of regression coefficients of maize-pumpkin mix cropping implied that expenditure on seed and fertilizer and irrigation had significant positive effect on gross return with estimated decreasing return to scale (0.85). According to estimated allocative efficiency indices, it is suggested to increase expenditure on seed and fertilizer cum irrigation by about 90% and 55% respectively. Extension of modern technologies with adjustment on resource use is to be encouraged for increase in productivity and profitability of maize-pumpkin mix crop production which indirectly promotes and ensure forage for pollinatorsJournal of Maize Research and Development (2015) 1(1):112-122DOI: http://dx.doi.org/10.5281/zenodo.34290

Analysis of energy flows and economic dynamics allows the diversity of variables involved in the agroecosystem production to be observed in the same dimension. In this way, efficiency and performance can be analysed integrally to identify critical points to be improved. The objective of this study was to analyse the energy-economic efficiency within three management strategies (Management I, Management II and Management III) of the maize agroecosystem in the Frailesca region of Chiapas (Mexico). The hypothesis was that systemic typologies, defined by modes of production, can lead to different efficiencies for the system performance. The study was descriptive; case studies were selected as representative based on their technological variants. The efficiency analysis was conducted using a balance of inputs and outputs expressed in energy and economic terms. Management III resulted in better energy use efficiency, with 6.47, while Management I and Management II were more economically feasible, with a benefit/cost ratio of 1.56 pesos.

Agronomic biofortification by seed treatments is a convenient way to harvest improved yields of micronutrient-enriched grains. This 2-year field study was conducted to evaluate the effects of seed priming with zinc (Zn), boron (B) and manganese (Mn) alone and in combinations on stand establishment, grain yield and biofortification of bread wheat (Triticum aestivum L.). Seeds of wheat cv. Faisalabad-2008 were soaked in aerated solutions of 0.5 m Zn, 0.01 m B and 0.1 m Mn, alone and in different combinations, for 12 h. Seed priming with the micronutrients was quite effective in improving stand establishment, yield-contributing traits, grain yield, and straw and grain micronutrient contents during both years. Best stand establishment was achieved from seed priming with Zn+B, followed by seed priming with Zn+Mn. Grain yield improvement from different seed priming treatments was in the order Zn+B > Zn+Mn > Zn > B > Mn > Zn+B+Mn, with respective increases of 34%, 33%, 21%, 19%, 18% and 8% relative to untreated seeds. Seed priming with Zn, B and Mn alone and in combinations also improved the contents of the respective micronutrients in straw and grain. All seed priming treatments were economically profitable except Zn+B+Mn, which was not cost-effective. The highest benefit : cost ratio accrued from seed priming with Zn+B. In conclusion, seed priming with micronutrients was generally cost-effective in meeting the crop micronutrient requirements, and in improving crop stand, grain yield and grain micronutrient contents in bread wheat. Seed priming with Zn+B was the most effective in this regard.

SUMMARYLong-term field experiments were conducted at Agra, Solapur and Hisar from 2000 to 2008 to identify efficient tillage and nutrient management practices and to develop predictive models that would describe the relationship between crop yields and monthly rainfall for rainfed pearl millet grown on arid and semi-arid Inceptisol, Vertisol and Aridisol soils. Nine treatments comprising a factorial combination of three tillage practices, viz., conventional tillage (CT), low tillage + interculture (LT1) and low tillage + herbicide (LT2) and three fertilizer treatments viz., 100% N from an organic source (F1), 50% organic N + 50% inorganic N (F2) and 100% inorganic N (F3) were tested in a split-plot design at the three locations. Studies revealed that tillage and fertilizer treatments, and their interactions, significantly influenced pearl millet grain yields at the three locations. Prediction models describing the relation between grain yield and monthly rainfall indicated that rainfall occurring in June, July and August at Agra; June and July at Solapur; and June and August at Hisar significantly influenced pearl millet grain yield attained by different treatments. The R2 values of the model ranged from 0.64 to 0.81 at Agra; 0.63 to 0.92 at Solapur, and 0.75 to 0.89 at Hisar. When averaged over all the treatment combinations, mean pearl millet grain yields varied from 1590 to 1744 kg ha−1 at Agra; 1424 to 1786 kg ha−1 at Solapur; and 1675 to 1766 kg ha−1 at Hisar while their corresponding sustainability yield indice (SYI) varied from 35.4 to 42.2%, 19.9 to 45.6% and 64.1 to 68.3%, respectively. At Agra (Inceptisol), CTF3 resulted in significantly higher mean net returns (Rs 11 439 ha−1), benefit-cost ratio (2.33), rainwater use efficiency (RWUE) (3.52 kg ha−1 mm−1) and the second best SYI (39.9%). At Solapur (Vertisol), the LT1F3 resulted in significantly higher net returns (Rs 12 818 ha−1), benefit-cost ratio (3.52), RWUE (3.89 kg ha−1 mm−1) and the fourth best SYI (42.6%). At Hisar (Aridisol), the LT1F3 treatment gave higher net returns (Rs 3866 ha−1), benefit-cost ratio (1.26), RWUE (5.05 kg ha−1 mm−1) and the fourth best SYI (67.8%). These treatment combinations can be recommended for their respective locations to achieve maximum RWUE, productivity and profitability.

The aim of this study is to find out effects of different trellis-vegetables grown at the edge of the rice field on the productivity and profitability of transplanted modern aman rice BINA Dhan-7. The study design was held as a Randomized Complete Block Design (RCBD) since it was repeated three times. The experimental treatments were T1 = rice + bottle gourd, T2 = rice + white gourd, T3 = rice + yard long bean, T4 = rice + bitter gourd and T5 = rice + cucumber. The results revealed that grain yield was the highest (3.48 t ha-1) in rice + cucumber (T5) and the lowest grain yield (2.65 t ha-1) was found in rice + bottle gourd (T1). In terms of vegetable production, the maximum vegetable yield (21.33 t ha-1) was obtained from rice + bottle gourd (T1) and the minimum value (0.25 t ha-1) was received from rice + cucumber (T5) crop combination. Moreover, the highest rice equivalent yield (23.98 t ha-1) was found from rice + bottle gourd (T1) crop combination and lowest value (3.48 t ha-1) was found from rice + cucumber (T5) crop combination. The highest value of gross return (Tk. 316290 ha-1) was obtained from the T1 treatment (rice + bottle gourd) and the lowest value of gross return (Tk. 50835 ha-1) was recorded from the treatment T5. The maximum benefit-cost ratio (3.35) was recorded from T1 treatment and the lowest benefit-cost ratio (0.71) was observed in T5 treatment. Finally, the growing of bottle gourd production at the edge of transplanted aman rice BINA Dhan-7 cultivation approach will be a significantly beneficial production technique.

The experiment was conducted at Multi Location Testing (MLT) site, Netrakona during rabi season of 2009-10 and 2010-11 to study the feasibility of intercropping of hybrid maize with different short duration vegetables and economic returns. Three intercrop combinations of hybrid maize along with sole maize were arranged in Randomized Complete Block Design replicated six times. There were four treatments viz., T1- Sole crop of maize, T2 - Three rows of red amaranth (25 cm apart) in between two (75 cm apart) rows of Maize, T3 - Three rows of bush bean (25 cm apart) in between two (75 cm apart) rows of Maize and T4 -Three rows of garden pea (25 cm apart) in between two (75 cm apart) rows of Maize. Yield contributing characters and yield of maize did not varied significantly due to intercropping with vegetables. The grain yield of maize in intercropped combination varied from 7.30-7.43 t/ha. But the highest grain yield (7.68 t/ha) was in sole maize. Maize equivalent yields in the intercrops ranged from 10.67-14.96 t/ha. The highest maize equivalent yield (14.96 t/ha), gross return (Tk. 224400/ha), gross margin (Tk.166830/ha) and benefit cost ratio (3.90) were obtained in maize + garden pea combination. The lowest maize equivalent yield (7.68 t/ha), gross return (Tk. 115200/ha), gross margin (Tk. 64128/ha) and benefit cost ratio (2.26) were obtained from sole crop of maize.

A field experiment on different maize cultivars planted at different sowing dates were accomplished at Kawasoti-5, Nawalparasi during spring season of 2013 to find suitable sowing date and maize cultivar for the location. Along with this, effect of sowing dates and maize cultivars on different agro-climatic indices were also calculated using formulas. Result showed that RML- 4/RML-17 produced higher kernel rows ear-1 (13.77), kernel per row (30.42) and test weight (244.9 g). Significantly higher grain yield was also found for RML-4/RML-17 (6.03 tha-1) compared to Poshilo makai-1 (4.73 t ha-1), Arun-2 (3.55 t ha-1) and Local (2.92 t ha-1). Earlier sowing date (7th April) produced higher kernel row-1 (27.97), kernel rows ear-1 (12.89) and 1000 grain weight (230 g). Significantly higher grain yield (5.13t ha-1) was obtained in earlier sowing date (7th April). Although the mean ambient temperature during research period was increasing with delayed sowing, days to attain different phenological stages decreased with late sowing. The statistically similar GDD was recorded for different sowing dates and higher PTI values were noticed with delay in planting. Similarly, heat use efficiency (HUE) was found higher in early sowing date. Arun-2 had small reduction in HUE so, it can be considered stable and best cultivar among the tested cultivars.

Background: Groundnut is one of the most important oilseed crops of Odisha and grown in both in kharif and rabi-summer seasons. Because of excessive vegetative growth in kharif season, the yield potential is lower than rabi-summer resulting in low yield. Keeping this in view, an experiment was set up to investigate the effect of different concentration and time of paclobutrazol application on growth and yield of groundnut.Methods: A field experiment was conducted during kharif 2016 to 2018 at AICRP on Groundnut Research Farm, OUAT, Bhubaneswar, Odisha. The experiment was laid out in split plot design with different concentration of paclobutrazol in main plot and time of application in sub plot and replicated thrice. Recommended dose of 20:40:40 kg of N, P2O5 and K2O entirely applied as basal. Yield and yield attributing characters were taken at the time of harvest.Conclusion: Application of paclobutrazol at different concentration significantly reduced groundnut plant height and significant reduction was observed with application at 30 DAE. Among various yield attributing characters; pod/plant and pod yield increased significantly (24.6% and 27.4%, respectively) with application of paclobutrazol @ 100 ppm with higher benefit cost ratio of 1.97 and upto (8.4% and 17.5%) with application at 30 DAE.
