Assessment of nutrient fortification and spacing on yield and economics of Bt cotton under protective irrigation

Abstract

The field experiment was conducted in Kharif season of 2017 at Agronomy farm, College of Agriculture, Nagpur to assess the effect of nutrient fortification and spacing on yield and economics of Bt cotton under protective irrigation. Four nutrient levels and three spacing’s were tested in split plot design with three replication and there were twelve treatment combinations. Study revealed that, higher seed cotton yield kg ha-1 was recorded with the treatment combination of 125% RDF fortified with humic acid under spacing of 90 cm x 45 cm (N4S1). But, it was remain at par with the treatment combination of 100% RDF fortified with humic acid under spacing of 90 cm x 45 cm (N1S1). Also, gross monetary returns, net monetary returns and B:C ratio were highest with the treatment combination of 125% RDF fortified with humic acid under spacing of 90 cm x 45 cm (N4S1).
