A field experiment was conducted at District Seed Farm, Kalyani, Bidhan Chandra Krishi Viswavidyalaya (22.97oN, 88.43oE, 9.75m MSL), Nadia, West Bengal, India during rabi season of 2014-16 to identify the optimum seed rate and variety for relay cropping with transplanted long duration kharif rice under changing onset of monsoon. The experiment was laid down in split plot design with three replications comprising of three lentil varieties (PL6, WBL 77 and NDL 1) in main plot and four seed rates (50, 60, 70 and 80 kg ha-1) in sub-plot. The varieties and seed rates significantly affected the plant population, pods per plant, biological and seed yield. The lentil variety PL 6 recorded highest seed yield (1446.8 kg ha-1) with the seed rate of 60 kg ha-1 followed by WBL 77 and NDL 1. Among the varieties PL6 recorded highest test weight (27.58 g) followed by NDL 1 (18.36 g) and WBL 77 (16.20 g). The variety PL 6 exhibited highest seed yield which was mainly attributed by the highest test weight of seeds along with moderate plant population m-2 and number of pods plant-1.

SUMMARYField trials are described in which the seed yield response of row-sown sesame to increasing plant population was examined, and in which row-sowing was compared with broadcasting at different seed rates. Maximum yields were obtained at an intended 200 to 250 × 103 plants ha−1 but yields were not greatly affected by a wider range of populations. Broadcasting, the normal local practice, gave yields slightly higher than those from rows 50 cm apart, the un-thinned rate of 800 × 103 viable seeds sown ha−1 yielded as well as treatments thinned to the optimum population, and double this seed rate, unthinned, gave the lowest yields, especially in rows.

Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, India during the summer (January – April) and kharif (June – September) seasons of 1994 and 1995 in a split plot design. The main plot consisted of three levels of irrigation, with irrigation water/cumulative pan evaporation (IW/CPE) ratios of 0.40, 0.60 and 0.80, and three levels of plant population (0.33, 0.44 and 0.66 million plants ha –1). The subplot treatments consisted of three levels of phosphorus (80, 100 and 120 kg P2O5 ha –1). The results revealed that irrigation at IW/CPE 0.80 with a plant population of 0.66 million plants ha –1 and a P level of 100 kg P2O5 ha –1 is promising in obtaining maximum yield in soybean. Under an irrigation regime of IW/CPE 0.80, the total water consumption varied from 450 to 533 mm, while it varied from 350 to 438 mm at IW/CPE 0.60 and from 250 to 393 mm at IW/CPE 0.40.

A field experiment was conducted at Main Agricultural Research Station, Dharwad during rainy season of 2015 and 2016 to study the effect of planting pattern and phosphorus management on production and profitability of intercropping system of mungbean and pigeonpea. The experiment was laid out in split plot design with three replications and eight treatments. Among them, four planting patterns [sole pigeonpea, mungbean + pigeonpea 1:3 (120 cm x 20 cm), mungbean + pigeonpea 1:2 (90 cm x 20 cm) and mungbean + pigeonpea 2:2 (90 cm x 20 cm)] were main plot treatments and two phosphorus levels (P2O5 @ 50 kg ha-1 and P2O5 @ 75 kg ha-1) were sub plot treatments. Based on pooled data the results revealed that, the significantly higher mungbean seed yield (424 kg ha-1) was recorded with application of 75 kg P2O5 as compared to 50 kg P2O5 ha-1. Whereas, in planting pattern, sole mungbean recorded significantly higher seed yield (757 kg ha-1) as compared to all other intercropping systems. Yield advantage indices and net returns were significantly higher in pigeonpea + mungbean (1:3) with 75 kg P2O5 ha-1 as compared to other treatments. This study indicated the need of fifty per cent higher dose of P2O5 for the pigeonpea and mungbean intercropping system (1:3) in northern transition zone of Karnataka.

A field experiment was conducted to study effect of various land configurations on soil moisture conservation and productivity of pigeonpea at experimental farm of AICRP for dry land Agriculture, V.N.M.K.V., Parbhani during kharif season of 2015 and 2016. Soil of experimental field was medium deep black with low in organic carbon, low in available nitrogen, medium in available phosphorus and high in available potassium.The experiment was laid out in split plot design with three main plot treatments and four sub plot treatments. The gross and net plot sizes are 7.2x5.4m2 and 5.4x3.6m2 respectively. The pigeonpea variety BDN-711 was used for sowing with spacing 90 x 20 cm. The main plot treatments were three land configurations as (L1) broad bed furrow (BBF), (L2) ridges and furrow and (L3) flat bed method. Sub plot treatments were four intercropping systems i.e. (I1) pigeonpea + soybean (2:1), (I2) pigeonpea + green gram (2:1), (I3) pigeonpea + black gram (2:1) and (I4) pigeonpea + cowpea (2:1). It was observed that seed yield of pigeon pea andpigeonpea equivalent yield were significantly affected due to different land configuration and intercropping systems. The highest pigeonpea seed yield (1588 kg ha-1) and pigeonpea equivalent yield (1823 kg ha-1) were obtained with Broad bed furrows (L1) followed by ridges and furrow (L2). Among the intercropping systems, pigeonpea + greengram intercropping system (I2) recorded higher seed yield (1574 kg ha-1) and pigeonpea equivalent yield(1832 kg ha-1).Periodical soil moisture observations in different land configuration considering depth of soil, higher average soil moisture was recorded under broad bed furrow followed by ridges and furrows while lesser was recorded under flat bed sowing.

The growth and yield characters of chickpea varieties suitable for mechanical harvesting were evaluated through field experiment conducted for three consecutive years (2016__17 to 2018__19) during rabi season on vertisols under rainfed conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh. The investigation was carried out in split plot design with three replications. Two plant geometries (30.0 × 10.0 cm and 22.5 × 10.0 cm) were assigned to main plots and six chickpea varieties (viz., GBM 2, Dheera, CSJ 515, HC 5, Phule G 08108 and BRC 1) were assigned to sub plots. Pooled analysis of experimental results indicated that significantly higher number of branches per plant (8.7) and number of pods per plant (31.1) and test weight (24.3 g) were observed under 30.0 × 10.0 cm when compared to 22.5 × 10.0 cm. Higher plant height (44.8 cm), height of lowest pod bearing branch (30.0 cm), lower days to 50 % flowering (42.1 days) and higher test weight (31.2 g) were observed in Dheera. Higher number of branches per plant (9.2) and number of pods per plant (34.2) were observed in GBM 2. Higher seed yield was observed in Phule G 08108 (1708 kg ha-1) which is followed by GBM 2 (1675 kg ha-1) Dheera (1569 kg ha-1) and BRC 1 (1493 kg ha-1). Higher harvest index (56.4%) was also observed in Phule G 08108. Chickpea varieties GBM2, Dheera and BRC1 were best suitable for mechanical harvesting and higher seed yield due to their excellent morphology.
