The identification of suitable conservation agricultural (CA) practices plays a significant role in global food security. A 3-year (2018-2020) field experiment was conducted in Vertisols of the semi-arid tropics of central India to investigate the effects of CA practices and irrigation methods on the yield, water productivity (WP) and energetics of chickpea (Cicer arietinum L.). A split-split plot design was used with three treatments, namely, two irrigation methods (sprinkler and furrow), three residue loads (30%, 60% and 100%) and three planting methods (broad-bed shaper-cum-planter [BBSP], zero-till planter and seed-cum-fertilizer drill) with three replications each. Sprinkler irrigation significantly improved chickpea seed yield by 2% and 5% in the second (1566 kg ha À1 ) and third years (1555 kg ha À1 ) compared to furrow irrigation.During the three experimental years, the WP of chickpeas under sprinkler irrigation was significantly higher ( p < 0.05) by 31%, 34% and 35% compared to that under furrow irrigation. Irrigation (6027 MJ ha À1 ), fertilization (1805 MJ ha À1 ) and planting (1615 MJ ha À1 ) accounted for 63%-68% of the total energy input in chickpea production. Under CA practices, it is recommended that higher returns be achieved using BBSP and a 100% residue load with sprinkler irrigation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
