Evaluation of carbon efficient production system through combine effects of tillage and Bioregulators on Rainfed chickpea (Cicer arietinum L.)

Abstract

The field experimentation was carried out at Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh, India during rabi season 2020-21 under rainfed conditions in loamy soil. ZT+R recorded highest total carbon output, net carbon output, carbon efficiency, carbon sustainable index and carbon efficiency ratio followed by zero tillage treatment and minimum reported under conventional tillage treatment. Among bioregulators foliar applications of salicylic acid (50 ppm) at flower initiation and pod filling recorded maximum in carbon efficiency and carbon sustainable index under all tillage treatments while total carbon output, carbon efficiency ratio and net carbon output reported maximum with KNO3(2%) applications under ZT+R while it was higher with SA (50 ppm) under ZT and CT.
