The results revealed that pigeonpea equivalent yield (PEY), land equivalent ratio (LER), gross return, net return, B: C ratio and monetary advantage index (MAI) were higher in normal planting during both the years of investigation. Both the planting systems (normal planting and paired row planting) were statistically at par to each other and significantly superior to sole planting. Total rainfall use efficiency and effective rainfall use efficiency were higher under normal planting of pigeonpea. Significantly higher yield attributes and yield, pigeonpea equivalent yield, land equivalent ratio, gross return, net return, B:C ratio and monetary advantage index were recorded with 100% RDF + 50% RDN +5 kg Zn ha −1. Highest total rainfall use efficiency and effective rainfall efficiency were also higher with 100% RDF + 50% RDN +5 kg Zn ha−1 during both the years of study.Read More
