Effect of liquid organic manures on sole and intercropping systems of baby corn and garden pea

A field experiment was conducted at Ramakrishna Mission Vivekananda Educational and Research Institute, Ranchi, during the winters of 2022-23 and 2023-24 to study the influence of liquid manures on crops under sole and intercropping systems of baby corn and garden peas. The experiment was placed in split plot design using 4 cropping systems in main plot (CS1: sole baby corn, CS2: sole garden pea, CS3: intercropping of baby corn and garden pea (1:1), CS4: intercropping of baby corn and garden pea (2:1)) and 4 liquid manure options in subplot (M1: control or no liquid manure, M2: Jiwamrit @ 10 %, M3: Kunapajala @ 10 %, M4: Panchagavya @ 10 %), replicated thrice. Pooled results indicated that the intercropping system of baby corn and garden pea, especially at a 1:1 ratio, grown using Kunapajala at 10% ensured the highest growth, yield attributes, and cob yield (2.09 t/ha) of baby corn over sole cropping. However, sole cropping grown using Kunapajala at 10% was found to be the best in realising the highest growth, yield attributes, seed yield (80.0 q/ha), and pod yield (145.5 q/ha) of garden peas over intercropping systems. Among the intercropping systems, 1:1 intercropping system of baby corn and garden pea performed better than 2:1 intercropping system. Further, among different intercropping systems, spraying of Kunapajala @ 10 % at 15, 30 and 45 days after sowing in 1:1 intercropping system of baby corn and garden pea ensured best system cob equivalent yield (4.17 t/ha), 60% yield advantage and high economic profitability (B:C of 6.06) and therefore, farmers of eastern plateau and hill zone of India can be benefitted by growing this intercropping system with the use of Kunapajala @ 10 %.
