Cluster bean is one of the major legumes cultivated in many parts of the world. However effect of organic seed pelleting in this crops needs more attention nowadays in probem soils like saline soil. Field experiments were carried out with cluster bean cv. Pusa Mausami to study the effect of organic seed pelleting on biometric, biophysical and yield parameters of clusterbean under saline condition. The seeds of cluster bean cv. Pusa Mausami were pelleted with pungam, prosopis, notchi, arappu leaf powders @ 50, 100, 150 and 200 g per kg. From the results, it was found that seed pelleting with pungam leaf powder @ 200 g per kg registered significantly higher values for biometric parameters viz., plant height, number of branches per plant, dry matter production, biophysical parameters viz., photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO2 concentration and yield parameters viz., pod length, number of pods per plant, pod yield per plant, number of seeds per pod, seed yield per plant and hundred seed weight. From the present study, it was concluded that seed pelleting with pungamn leaf powder @ 200 g per kg can be recommended for increased growth and yield parameters in cluster bean under saline conditions.

Field experiments were conducted during Kharif-2017 and 2018 at ICAR-Krishi Vigyan Kendra (KVK), Mangaluru of coastal Karnataka to study the effect of integration of organic and inorganic sources of nitrogen on the yield of midland rice. The results indicated that the integration of organic and inorganic sources of nitrogen significantly influenced the growth and yield attributes of rice. The highest grain yield (5434 and 5372 kg ha-1) and straw yield (6817 and 6927 kg ha-1) were recorded in the treatment comprising VC substituted with 50 percent recommended dose of nitrogen which was on par with PM substituted at 50 percent in both the years. A similar trend was also noticed in both the years for the growth and yield parameters where the highest plant height (94.93 and 96.30 cm) highest productive tillers (16.85 and 18.12) and longer panicle length (17.54 and 18.65 cm) was recorded in the treatment where 50 percent nitrogen was substituted by vermicompost compared to control. The remaining treatments of organic substitution ratios with urea also had a beneficial effect on yield and yield parameters of rice compared to control.

Cluster bean (Cyamopsis tetragonoloba (L.) Taub.) is an important legume crop. Investigations were undertaken to study the effect of seed pelleting with botanicals viz., Pongamia pinnata, Prosopis juliflora, Vitex nigundo and Albizia amara@ 50, 100, 150 and 200 g kg-1 of seed on germination and seedling growth of cluster bean under induced saline condition viz., EC4, EC8, EC12 and EC16. The experimental results revealed that increased salinity caused harmful effects on germination and seedling growth in terms of germination %, speed of germination, root length, shoot length, dry matter production and vigour index. However, pelleting treatments increased these parameters with more pronounced effect by Pongamia pinnata leaf powder. Higher germination, growth and vigour of seedlings were recorded with Pongamia pinnata leaf powder treatment @ 200g per kg. The next best levels of vigour index was recorded in treatments with Pongamia pinnata leaf powder @ 150g per kg and Prosopis juliflora leaf powder @ 200g per kg only at no salinity and low levels and in high levels of salinity, Albizia amara leaf powder treatment @ 200g per kg performed as the nest best treatment.

Field experiments were conducted to evaluate competitive effects of johnsongrass and sicklepod on growth and yield of irrigated and nonirrigated soybeans. Johnsongrass reduced soybean growth early in the growing season. Sicklepod was competitive all season, but competitiveness was greatest during the soybean reproductive stage. Soybean yields were reduced 31% by sicklepod, 14% by johnsongrass, and 36% by both weeds growing together. Nonirrigated soybeans yielded less than irrigated, but percent yield reductions were similar. Johnsongrass dry matter production and seed yield were reduced more than sicklepod by soybean interference. Soybean and sicklepod interference reduced johnsongrass seed production 73 to 95%. Johnsongrass produced 245 to 1238 seeds per plant when interfering with soybeans and sicklepod. Sicklepod seeds per plant were reduced 6 to 31% by johnsongrass interference and 47 to 75% by soybeans and soybeans plus johnsongrass.

Field experiments were conducted during the summer (February-May) and south west monsoon (June-September) seasons of 1996 and 1997 at the Aliyarnagar Agricultural Research Station of Tamil Nadu Agricultural University, India, to study the growth and yield of soybean in response to irrigation, composted coir pith, time of N, P, K application and use of a nutrient mixture spray. The results revealed that irrigation at 0.90 IW/CPE [ratio of Irrigation Water Depth (IW) to Cumulative Pan Evaporation (CPE)], the application of composted coir pith and the split application of N, P and K in conjunction with a nutrient mixture spray significantly increased the plant height, leaf area index, dry matter production and grain yield of soybean. However, the root length of soybean was significantly reduced by irrigating at 0.90 IW/CPE (compared to irrigation at 0.70 IW/CPE and 0.50 IW/CPE) and by the application of composted coir pith.

Two field experiments were carried out during the cropping seasons of 2016 and 2017 at the Teaching and Research Farm of the University of Agriculture, Makurdi, Benue State, Nigeria. The experiments sought to determine the effect of sweet potato vine orientation on growth and yield of sweet potato/maize intercropping system with a view to improve the productivity of maize/sweet potato intercropping in Makurdi. The experiment was a 2 x 2 x 3 split-split plot laid out in randomized complete block design with three replications. The main plot treatments were two cropping systems [sole cropping (sweet potato, maize), intercropping (sweet potato + maize)].The sub plot treatments were made up of two maize varieties (pop.66SR/ACR.91 SUWAH 1-SR and M2: pool18R/AK94DMRESR-Y). The sub-sub plot treatments comprised of three (3) sweet potato vine orientations (incline, loop and horizontal). The result obtained from the experiment showed sole cropping gave higher cob length, number of seeds per cob, cob weight, grain yield and 100-seed weight of maize than intercropping in both years. In all years, pool18R/AK94DMRESR-Y produced higher yield and yield parameters of maize than pop.66SR/ACR.91 SUWAH 1-SR irrespective of the cropping system. In 2016 and 2017, horizontal vine orientation gave higher vine length, root diameter, root length, number of saleable roots per hectare and weight of saleable roots than all the other vine orientations. Intercropping with pop.66SR/ACR.91 SUWAH 1-SR gave higher growth and yield parameters than intercropping with pool18R/AK94DMRESR-Y. All intercrop combinations had LER figures above 1.0 and LEC values above 0.25 in both years. CR values of sweet potato were consistently higher than those of maize in all intercrop combinations in 2016 and 2017

Field experiments were conducted in silty clay soil, to study the effect of using the modified subsoiler-moldboard plow (MSMP) on some soil properties (bulk density, penetration resistance and electrical conductivity) and on some of broad bean growth and yield parameters (emergency rate, plant height, frock number, pods number per plant, seeds number per pods, weight of 1000 seeds, and total yield). The experiment parameters were three depths of subsoiler as a part of MSMP (30,40 and 50cm) and two depths of moldboard as a part of MSMP (20 and 30cm). The results showed that increasing the subsoiler depth from 30 to 40 cm resulted in redusing the bulk density and electrical conductivity of the soil by 2.70 and 8.29%, respectively, while increased the growth and yield parameters by 10.17, 14.29, 33.43, 7.37, 21.46, 27.31 and 45%, respectively. Increasing the subsoiler depth from 40 to 50cm decreased the soil bulk density and electrical conductivity by 1.85 and 0.60% respectively, whereas the growth and yield parameters increased by 10.22, 37.50, 49.89, 93.13 35.34, 33.34 and 117.67% respectively. The increase of the moldboard depths from 20 to 30cm leaded to increase the growth and yield parameters by 23.16%, 24.70%, 67.46%, 57.51%, 34.38%, 20.33% and 68.16% respectively. The subsoiler and moldboard depths (50 and 30cm) gave the highest emergence rate, plant height, weight of 1000 seeds and yield by 71.61%, 109.42%, 111.01% and 407.46% compared with the shallow depths of subsoiler and moldboard plow depths (30 and 20cm respectively). The results revealed that the values of the soil properties decreased by 12.50%, 60.31% and 40.86%, respectively after tillage, whereas they increased by 17.35%, 250.68% and 169.09%, respectively before harvest.

Cowpea (Vigna unguiculata) is an important legume crop. Investigations were undertaken to study the effect of seed hardening, seed pelleting and combined effect of seed hardening with seed pelleting on germination and seedling growth of cowpea under induced saline condition viz., EC4, EC8, EC12 and EC16. Cowpea seeds were hardened with KCl @ 1%, CaCl2 @ 1% and both KCl and CaCl2 @ 1% and hardened seeds were further pelleted with pungam leaf powder @ 100, 150 and 200 g kg-1 of seed. Observations on germination % and seedling parameters were recorded. The experimental results revealed that increased salinity reduced germination and seedling growth in terms of germination %, speed of germination, root length, shoot length, dry matter production and vigour index. However, hardening and pelleting treatments significantly increased all these parameters at all the levels of salinity when compared to control. Among the treatments, seeds hardened with KCl @ 1 % + CaCl2 @ 1 % and pelleted with pungam leaf powder @ 200 g per kg recorded higher germination % and all the seedling parameters when compared to control and other treatments.
