A field experiment was conducted during <italic>kharif</italic> season of 2005 and 2006 to find out the plant density and fertility levels of <italic>kharif</italic> groundnut (<italic>Arachis hypogaea</italic>) – pigeon pea (<italic>Cajanus cajan</italic>) intercropping system. Growing of groundnut as sole crop recorded higher pod yield (1490 kg ha<sup>−1</sup>) over groundnut in intercropping system. The highest pod yield (889 kg ha<sup>−1</sup>) of groundnut among the intercropping system was obtained with the treatment received 100 % of both RDF and plant density of groundnut and pigeon pea respectively. Which was closely followed by T<sub>9</sub> (850 kg ha<sup>−1</sup>), T<sub>2</sub> (846 kg ha<sup>−1</sup>), T<sub>11</sub> (828 kg ha<sup>−1</sup>) and (825 kg ha<sup>−1</sup>) and they were statistically at par among each other. Growing of pigeon pea as sole crop recorded higher <sup>T</sup>10 grain yield (1584 kg ha<sup>−1</sup>) over pigeon pea in intercropping system. Among the intercropping system the maximum pigeon pea grain yield was found in T<sub>1</sub> (1013kg ha<sup>−1</sup>) which was at par with T<sub>10</sub> (978 kg ha<sup>−1</sup>), T<sub>11</sub> (950 kg ha <sup>−1</sup>), T<sub>2</sub> (946 kg ha<sup>−1</sup>), T<sub>9</sub> (939 kg ha<sup>−1</sup>), and T<sub>5</sub> (903 kg ha<sup>−1</sup>). Among the cropping systems, intercropping of groundnut with pigeon pea resulted in maximum groundnut equivalent yield (2155 kg ha<sup>−1</sup>) in T<sub>1</sub>. Among the intercropping systems, groundnut with pigeon pea in 4:2 row proportions with 100% both plant density and RDF in all the crops was most remunerative in respect of net return (Rs.28400) and economic return: cost ratio (2.85).

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.

The effects of two tillage methods (zero tillage and conventional tillage), two residue managements (residue kept and residue removed) and two levels of cropping system (maize + soybean and sole maize) were studied over 3 years (2015-2017) at Dailekh district of Nepal. Arun-2 and Puja were the varieties of maize and soybean used respectively, followed by winter wheat. The results revealed that the maize + soybean system had significantly higher plant population and ear population (34.83 thousands ha-1 and 34.35 thousands ha-1, respectively), grains per row (37.1), ear length (16.6 cm) and 20.5% higher grain yield as compared to sole maize. The highest maize equivalent yield (7.92 t ha-1) was recorded in maize + soybean as compared to the lower grain yield equivalent (7.06 t ha-1) in sole maize. Zero tillage accounted relatively higher benefits (high net income and B:C ratio) as compared to conventional tillage. The residue kept plot resulted significantly higher B:C ratio (2.41) than the residue removed (2.11) and the maize + soybean recorded 82.5% greater B:C ratio compared to sole maize. Net annual income was significantly higher in zero tillage, residue kept and maize + soybean system (NRs. 223072.00, 222958.00 and 269016.00 ha-1 respectively). Such combinations are recommended for Dailekh district of Nepal to have profitable crop productivity. SAARC J. Agri., 17(1): 49-63 (2019)

SUMMARYField studies were made for 2 years on a sandy loam soil under dryland conditions of north-west India with three pigeon-pea varieties in relation to plant density and the application of phosphate fertilizer. Varieties Pusa Ageti and P4785 with better developed root system and profuse nodulation had higher grain and stalk yield, and higher N and P yield than Prabhat. Root and shoot growth and root nodulation were adversely affected with increasing plant densities in the range 50 × 103 and 150 × 103 plants/ha. Stalk and total N and P yield increased with increasing plant density. Plant density of 117 × 103 plants/ha produced maximum grain yield of 1·53 t/ha. Phosphorus fertilizer promoted root and shoot growth, intensity and volume of nodulation and increased grain, stalk, N and P yield. The effect of plant density on grain yield was more pronounced in the presence of phosphate fertilizer. The economic optimum rate of P ranged between 22·1 and 23·1 kg/ha under different plant densities.

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

AbstractIn order to enhance sustainable intensification of potato-based cropping systems, especially in sub-Saharan Africa (SSA), there is a need to investigate the economic viability of investing in this lucrative venture. This study evaluated the economic returns under legume intercropping systems using value/cost ratio (VCR) and benefit/cost ratio (BCR) under treatments comprising of potato intercropped with dolichos (Lablab purpureus L.) (P-D), climbing bean (Phaseolus vulgaris L.) (P-B) and garden pea (Pisum sativum L.) (P-G), and a potato pure stand control (P-S). Across the seasons, tuber yield was not significantly (p < 0.05) affected by intercropping with P-D, whereas under P-B and P-G, it decreased by 19% and 16%, respectively compared to P-S. P-G, P-B and P-D recorded 6, 7 and 12% higher potato equivalent yield (PEY) relative to P-S. P-D was the most profitable intercropping system with VCR of 35 and BCR of 5.1 as compared to values recorded in P-S of 31 and 5, respectively. Regression of VCR against PEY resulted in a stronger coefficient (0.98) compared to that of BCR against PEY (0.82) implying that VCR is a simple tool that could be adopted for economic returns to investment studies such as potato-legume inter-cropping systems.

To study the effect of nutrient management strategy on production potentiality of short duration high yielding summer irrigated groundnut variety TG 51, field experiments were conducted during summer seasons of 2011 and 2012 at Bidhan Chandra Krishi Viswavidyalaya, West Bengal. Results revealed that, application of 100 % RDF + 7.5 t/ha FYM as basal increased growth and yield attributes that led to significantly higher productivity (pod yield 3320 kg/ha) besides enrichment of soil available nutrients after harvest of the crop. Pod yield decreased with further increase in NPK fertilizer above 100% RDF. However, maximum haulm yield (3979kg/ha) was recorded with 150% RDF + 7.5t/ha FYM as basal. Maximum net return: cost ratio (3.43) was found with 100 % RDF which was closely followed by that of 100 % RDF + 7.5 t/ha FYM.

A 2-factorial experiment, involving three levels of phosphorus (0, 40, and 80 kg/ha) and four cropping systems (mono crop, maize–cowpea inter-row, maize–cowpea intra-row, and maize–cowpea intra-hole cropping) was conducted in the field for two consecutive years in 2003 and 2004 at Nietvoorbij (33°54′S, 18°14′E), Stellenbosch, South Africa. Plant density (number of plants per hectare) was 166 666 for sole cowpea, 111 111 for maize–cowpea inter-row, 55 555 for maize–cowpea intra-row and 55 555 for maize–cowpea intra-hole cropping. Applying 40 or 80 kg phosphorus (P)/ha significantly increased cowpea grain yields by 59–65% in 2003 and 44–55% in 2004. With maize, the increases in grain yield were 20–37% in 2003 and 48–55% in 2004 relative to the zero-P control. In both cropping seasons, the number of pod-bearing peduncles per plant, the number of pods per plant, the number of seeds per pod, and grain yield per cowpea plant were significantly increased with the application of exogenous P. In contrast, the number of pod-bearing peduncles per plant, the number of pods per plant, the number of seeds per pod, and the grain yield per plant were all significantly depressed by mixed culture relative to mono crop cowpea. There was also a significant interactive effect of P and cropping system on cowpea, such that, all cowpea yield components were generally lower in intercrop relative to mono crop. In all instances, the yield component of mono crop cowpea and, to some extent, inter-row cowpea, were markedly increased by the provision of 40 or 80 kg P/ha relative to the zero-P control. Intercropping maize with cowpea produced higher total yields per unit land area than the mono crop counterpart.

Mixed crop cultivation of lentil and rapeseed could be a promising technology for yield maximization. The field experiment was carried out at multilocation testing site, Kashinathpur, Pabna during the rabi season of 2011-12 and 2012-13 to verify the performance of rapeseed as mixed crop with lentil at different seeding ratios. The treatment comprises for the experiment were T1: Sole lentil (100%), T2: Sole rapeseed (100%), T3: Lentil (100%) + Rapeseed (10%), T4: Lentil (100%) + Rapeseed (20%), T5: Lentil (100%) + Rapeseed (30%) and T6 :Farmers’ practice :Lentil (100%) + Rapeseed (15%). The highest lentil equivalent yield (2.22 t ha-1 in and 2.48 ) and maximum land equivalent ratios (1.27 and 1.28) were observed in T4 treatment in 2011-12 and 2012-13, respectively.. It was noted that all the mixed cropping systems produced higher equivalent yield and LER than that of their corresponding sole crops. . Cost and return analysis showed that the highest net return (Tk. 127774 ha-1) was found in T4 treatment while sole rapeseed gave the lowest net return (Tk. 60540 ha-1). Net return was always higher under mixed cropping system than that of sole cropping. The highest benefit cost ratio 3.48 was recorded from Lentil (100%) + Rapeseed (20%) where as the minimum (1.39) from soli rapeseed.Bangladesh Agron. J. 2014, 17(1): 33-40

An experiment was conducted in charland at the Multi Location Testing (MLT) site Bhuapur, Tangail during 2012-13 and 2013-14 under AEZ-8 to find out the suitable intercropping system of hybrid maize with different short duration vegetables with economic return. The experiment was laid out in RCB design with six dispersed (six farmers’ field) replications. The hybrid maize (ver. BARI Hybrid maize-7), potato (Diamant), spinach (local), red amaranth (BARI Lalsak-1), Radish (BARI Mula-1) were used as the planting materials. Five treatment combinations viz. T1= Sole Maize, T2= 100% Maize (maize paired row) + Potato (var. Diamant), T3= 100% Maize (maize paired row) + Spinach (var. local), T4= 100% Maize (maize paired row) + Red amaranth (var. BARI Lalshak-1) and T5= 100% Maize (Maize paired row) + Radish (var. BARI Mula-1) were studied. Maize grain yield in intercropped combination varied from 5.59-7.62 t ha-1. But the highest grain yield (8.17 t ha-1) was obtained from sole maize. Maize equivalent yields in the intercrops situation ranged from 11.39-19.68 t ha-1 where highest maize equivalent yield 19.68 t ha-1 was recorded from the treatment T3 (100 % maize + spinach). The same combinations also gave highest gross return (Tk. 373930 ha-1) and gross margin (Tk. 258585 ha-1) as well as benefit cost ratio (3.24). Though highest grain yield was recorded from sole maize but equivalent yield and economic return was much lower than the treatment T3.Bangladesh Agron. J. 2015, 18(2): 65-69

The research on, ‘Studies on rainwater harvesting and reutilization for protective irrigation with farm pond’ was conducted during the year 2016-17 at demonstration farm of the Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The daily depth of water impounded in the farm pond was recorded for developing stage-storage relationship of the farm pond. For estimation of the loss of water through evaporation from farm pond, daily pan evaporation data was multiplied by pan co-efficient (0.70). The harvested water in the farm pond was utilized for applying protective irrigation to the pigeon pea crop. The experiment consisted six replications and two treatments. One protective irrigation for pigeon pea at pod development stage (T1) was applied on 30.11.2016. The treatment T2 consisted without protective irrigation to pigeon pea. The grain yield of pigeon pea was recorded plot wise.The grain yield data was analyzed using MAUSTAT software and results obtained were compared treatment wise. For economic analysis of the treatments, cost of cultivation, cost of cultural operations, fixed and operational costs of pump and accessories were calculated. These total cost was be used to determine the gross monetary returns (GMR), net monetary returns (NMR) and benefit cost ratio (B:C ratio). The area of top section and bottom section of the farm pond was 279.75 m2 and 516.82 m2 respectively. The average elevation of embankment at top was 413.130m. The average elevation of bottom of pond was 410.210m. The elevation at the bottom of outlet was 412.437m. The maximum depth of water impounded and maximum storage volume in the farm pond was 2.165m and 933.99m3 respectively. The total water evaporated through farm pond for the month of July, August, September, October, November and December 2016 was found to be 19.14 m3, 32.60m3, 25.40 m3, 35.9882m3, 29.8620m3 and 1.1965 m3 respectively. The maximum water evaporated through the farm pond was recorded in the month of October-2016. Total evaporation loss through the farm pond recorded was144.17 m3.The seepage loss through the pond for the month of July August, September, October, November and December 2016 was found to 634.88, 358.05 m3, 651.80 m3, 611.64 m3, 147.33 m3, and 37.89 m3 respectively. The maximum water seepage through the farm pond was recorded in the month of September -2016.The total seepage loss recorded through the farm pond was 2441.59 m3. The harvested water in the farm pond was utilized for irrigating the pigeon pea crop at its pod development stage. One of protective irrigation (T1) recorded significantly higher pigeon pea grain yield than treatment of without protective irrigation (T2). Due to the one protective irrigation, 27.30 per cent grain yield increased over or control was observed. The study revealed that the treatment T1 i. e. one protective irrigations at pod development stage recorded highest GMR (111302.00Rs/ha) and NMR (76302.00) as compared to control (T2) i. e. without protective irrigation. The benefit- cost ratio (2.18) is found to be higher under the treatment T1i. e. one protective irrigation pod development stage. The lowest B:C ratio (1.69) is estimated under the treatment T2 (without protective irrigation).
