Abstract

A field experiment was conducted during the rabi-cum-hot weather season of 2004–05 at Dapoli, to study the productivity, land-equivalent ratio and economics of groundnut (Arachis hypogaea) + sweet corn (Zea mays saccharata) intercropping system at different fertility levels and row proportions. The dry pod yield, haulm yield of groundnut and green cob yield and green biomass yield of sweet corn were highest in case of sole planting and application of 125% RDF (recommended dose of fertilizers). In case of intercropping situation groundnut + sweet corn in ratio of 3:1 and supplemented with 125% RDF recorded higher dry pod yield while higher green cob yield were recorded at 1:1 row proportion. The maximum value of LER was recorded due to intercropping at 3:1 ratio and supplied with 100% RDF. The net returns and B:C ratio were highest due to sole planting of sweet corn grown with 125% RDF followed by groundnut + sweet corn in ratio of 1:1 and supplemented with 125% RDF.
