Abstract

F transplanted pigeonpea and sunflower intercropping system at ield experiment was conducted during 2019 to evaluate Kharif different dates of sowing and fertilizers. Treatment combinations consists of two sowing time and eight intercropping system replicated thrice. Pigeonpea transplanted in second fortnight of July recorded significantly higher grain yield, equivalent yields of pigeonpea (PEY) and sunflower (SEY), over second fortnight of August. However, higher sunflower seed yield and oil content was recorded in second fortnight of August sowing. Among intercropping systems, sole pigeonpea and sunflower recorded significantly higher seed yield (2254 and 1781 kg ha ) -1 over sole drilled pigeonpea as well as intercropping systems. Transplanted pigeonpea + sunflower (1:2) with RDF for both crops recorded superior pigeonpea grain yield (1936 kg ha ), PEY (2914 kg ha ), SEY (3816 kg ha ), gross returns (Rs. 157680 ha ) and net returns (Rs.
