Impact of Kharif Rice Establishment Systems and Succeeding Tillage Practices on Rooting Behaviour of Succeeding Chickpea, Blackgram and Mustard

Abstract

Background: The present experiment was designed to evaluate the role of emerging rice establishment systems compared with succeeding tillage practices in supporting the rooting behaviour of chickpea, blackgram and mustard grown in succession. Methods: The current experiment was conducted in kharif followed by rabi during 2021-22 and 2022-23 in a split-split plot design with three rice establishment methods as main plots during kharif followed by two tillage systems as sub plots and in each sub plot, chickpea, blackgran and mustard were grown as sub-sub plot during rabi, after the harvest of kharif rice. Results: Rabi crops grown after dry direct seeded rice following conventional tillage has recorded highest root length and root volume in chickpea (23.83 and 22.97 cm; 13.57 and 13.13 cc), blackgram (20.70 and 20.13 cm; 12.43 and 12.03 cc) and mustard (37.43 and 36.27 cm; 21.50 and 20.80 cc) during successive years of study i.e., 2021-22 and 2022-23, respectively.
