Abstract

Pulses play a major role in providing overall prosperity to the small and marginal farmers through nutritional security by meeting their dietary protein requirements and improving production base through conservation of natural resources. Inclusion of pulses in the cropping system as a crop rotation improves soil fertility and crop productivity of cereals and oil seeds. Chickpea is one of the important pulses cultivated in Vertisols during winter season. We examined chickpea cultivars for energy use efficiency, economics, physiological efficiency and water use efficiency (WUE) under different rainfall situations for their sustainable yield and overall profit, in Vertisols of semi-arid tropics of South India. Results revealed that low input energy and high grain and stover yields of cultivars result in higher total output energy and net benefit energy. Higher dry matter efficiency of 0.702 was observed with medium-duration cultivar, whereas WUE was higher in short-duration cultivar followed by medium-duration cultivar. We conclude that medium- duration cultivar and short-duration cultivar are more suitable for the SAT region in terms of greater energy benefits, higher income per unit area, physiological efficiency and water use efficiency. Thus short-duration cultivar could be cultivated during normal to above normal rainfall years and during normal to drought years in winter season on residual soil moisture in Vertisols medium-duration cultivar for higher energy efficiency and economics.

Abstract

A field study was conducted during Rabi season in 2014-15 in the Krishi Vignana Kendra Hirehally, Tumkur District to study the effect of mulches. The experiment was conducted in 4 replications of black polythene mulched and unmulched treatment in green chilli, hybrid MHCP 317-Sierra, variety of Mahyco company. Primary and secondary branches were maximum in black polythene mulched (14&23), and least in unmulched (10&17) plots. The significant increase of 38% green chilli yield in mulched, compared to unmulched plots, was maximum (20.20 tonne per ha and 12.50 tonne per ha respectively). Mulched treatment reduces labour cost up to 39% compared to unmulched, which is highest among variable costs. The use of black polythene mulch in sweet pepper brought the benefit cost ratio from 2.61 to 2.81.
