Patil use efficiency, economics, physiological efficiency and water

Patil et al. (2014) studied about 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/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.
