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.
