Yield and economics of maize under maize-based cropping system in Kymore Plateau of Madhya Pradesh

Abstract

A field experiment was conducted in a clay loam texture soil during 2017-18 and 2018-19 at Research Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) to study the yield and economics of maize cultivars under maize based cropping systems in Kymore Plateau of Madhya Pradesh. The grain and straw yield was recorded significantly superior under maize (hybrid) - chickpea (6316 and 6532 kg/ha; 9065 and 9099 kg/ha) followed by maize (hybrid) - field pea (6291 and 6497 kg/ha; 9044 and 9084 kg/ha) and maize (hybrid) - berseem (6274 and 6476 kg/ha; 9017 and 9064 kg/ha) during two respective years. Significantly maximum HI was assessed under maize (hybrid) - chickpea (41.09 and 41.79 %) followed by maize (hybrid)- field pea (41.03 and 41.70 %) and maize (hybrid) – berseem (41.02 and 41.68 %). Significantly maximum harvest index was assessed under maize (hybrid) - chickpea (41.09 and 41.79 %) followed by maize (hybrid)- field pea (41.03 and 41.70 %) and maize (hybrid) – berseem (41.02 and 41.68 %). Net returns was recorded significantly greater under maize (hybrid) -chickpea (`66127/ha) followed by maize (hybrid)-field pea (`65740/ ha) and maize (hybrid) – berseem (`65473/ha). However, B:C ratio was obtained maximum under maize (hybrid) -chickpea (2.69) followed by maize (hybrid)-field pea (2.67) and maize (hybrid) – berseem (2.66).
