Productivity of chickpea (Cicer arietinum L.)-mustard (Brassica juncea L.) intercropping under various fertility levels and row combinations

Abstract

A field experiment was carried out on silt loam soil of the Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during winter (rabi) season of 2015-16 & 2016-17 to study the productivity of chickpea (Cicer arietinum L.)- mustard (Brassica juncea L.) intercropping under various fertility levels and row combinations. Growth and yield attributes, grain and straw yields of chickpea and mustard were affected significantly with fertility levels and row combinations. Fertilizer level at 125% RDF recorded higher chickpea yield equivalent and land equivalent ratio over fertilizer level 75% RDF and 100% RDF. Sole crop of chickpea, being statistically at par with chickpea- mustard intercropping row ratio 6:1 and 4:1, resulted highest chickpea yield equivalent over sole crop of mustard, rest of the row combinations. Higher value of land equivalent ratio (LER) was recorded in fertility level 125% RDF and row combination 2:2.
