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.

AbstractThe 1996 farm bill challenges agricultural producers to pursue conservation objectives while allowing flexibility and reducing subsidies. The nature of this challenge for semi-arid rainfed, wind-erosion-prone agriculture is explored via a behavioral model. Simulations of farm-firm decision making under scenarios in the southern Texas High Plains are evaluated. Results indicate that the removal of subsidies, while lowering farm incomes, does not, under most assumptions, alter cropping system choice. Alternatively, under a variety of assumptions, the imposition of an erosion tax shuts down cropping.

Continuous adoption of Pearl millet-Wheat cropping system led to reduction in productivity which put a serious threat to its sustainability in semi-arid eastern plain zone of Rajasthan, India. Crop diversification with wider choice with a variety of crops is being promoted as an alternative to profit maximization with enhanced soil fertility status. Therefore, a long term experiment was initiated to evaluate the production potential, sustainability, resource-use efficiency and economics of nine Pearl millet based cropping systems. Result revealed that system productivity in terms of pearl millet equivalent yield (PMEY) was highest (30488 kg ha-1) with groundnut-wheat-cluster bean-onion crop rotation. Moreover, groundnut-wheat-cluster bean-onion recorded the highest SYI and land use efficiency (0.65 and 73.97%) followed by pearl millet-wheat-cluster bean-barley sequence (0.63 and 65.75%). The groundnut-wheat-cluster bean-onion also generated highest number of man days/ha/year (405). The highest values of organic carbon were found under green gram-mustard-pearl millet-lentil and cluster bean-pea-pearl millet-lentil. The maximum value of available P was recorded with cluster bean-mustard-green gram-garden cress followed by the groundnut-wheat-cluster bean-onion sequence. Available K decreased significantly from their initial values in all the cropping systems except groundnut-wheat-cluster bean-onion crop rotation. Among the various systems, groundnut-wheat-cluster bean-onion realized the highest net returns ( 213000 ha-1), followed by pearl millet-wheat-cluster bean-barley ( 163254 ha-1). Overall, it can be concluded that under the semi-arid agro climatic conditions of Rajasthan, groundnut-wheat-cluster bean-onion, followed by pearl millet-wheat-cluster bean-barley, were more productive, sustainable, resource use efficient and remunerative than other cropping systems.

An experiment was carried out during the Rabi season of 2016, to study the impact of foliar spray of nutrients and seed treatment on protein uptake and protein yield of lathyrus (Lathyrus sativus L.) Under relay cropping system at the Agronomy Research Farm of IGKV, Raipur.The experiment was laid out in Factorial Randomized Block Design with twelve treatments replicated thrice. highest cost of cultivation, gross return, net return and B:C ratio was found in treatment F5: 0.5% NPK (19:19:19) spray at branching and 15 days after 1st spray (11570.50, 29492.64, 18618.14, 1.712 Rs.ha-1, respectively), where as in case of seed treatment S2: seed treatment with Sodium molybdate @ 0.5 g kg-1 seed gave the maximum cost of cultivation, gross return, net return and B:C ratio (11308.17, 26475.39, 15583.39, 1.431 Rs.ha-1 , respectively).

Trends in reference evapotranspiration (ETo) estimated using Penman-Monteith equation were analysed over arid, semi-arid and humid regions of northwest (NW) India during 1985–2018. The MannKendall is used to determine significance of trends. Theil-Sen’s estimator and least square linear fitting methods are adopted to find slopes of the trend lines. The results indicated a significant decrease in ETo on annual basis for most of the locations and NW India as a whole. However, the trend was not statisticallysignificant for seasonal ETo. The significant decrease in solar radiation and wind speed nullified the impact of increased temperature and resulted in slight decrease in ETo over arid and semi-arid regions of NW India which could probably be attributed to the increased dust hazy conditions prevailing. In NW India, water is a limiting resource the decrease in ETo may help researchers in decision makers to develop water assets and utilize the irrigation systems more effectively. There was also an increasing trend in production of major crops in the study region. Further, in near future, if this decreasing ETo trend were to remain, it would help in intensification of cropping system with the existing water resource.
