Effect of varied fertilizer levels on productivity and economics of sunflower based cropping systems

Abstract

A field experiment was conducted during 2018-19 to 2020-21 to study the effect of different preceding crops and fertilizer levels on yield and economics of rabi sunflower at Agricultural Research Station, Tornala, Professor Jayashankar Telangana State Agricultural University. The results revealed that, among different cropping systems, Greengram – sunflower cropping system recorded significantly higher sunflower equivalent yield (2202 kg ha-1), gross (Rs.1,26,948 ha-1) and net returns (Rs. 68,659 ha-1), whereas, foxtail millet – sunflower recorded higher B:C ratio (2.21). Among fertilizer treatments, 100% RDF (75:90:30 N:P2O5:K2O kg ha-1) recorded higher sunflower equivalent yield, gross returns, net returns and B:C ratio (2054 kg ha-1, Rs.1,18,064 ha-1, Rs. 57,082 ha-1 and 1.94),respectively.
