Effect of sowing windows and varieties on growth, yield and oil content of groundnut (Arachis hypogaea L.)during rabi season in Northern Transition Zone of Karnataka

Abstract

A field experiment was conducted on to assess the productivity of groundnut varieties under different sowingwindows during rabi season in Northern Transition Zone of Karnataka” at MARS, Dharwad during2020-21. The experimentwas laid out in strip- plot design with three replications consisting of three sowing windows as vertical factor and fourvarieties as horizontal factor . Groundnut sown on 48th MW recorded significantly higher pod yield (2805 kg ha-1) and at parwith 52nd MW. The pod yield was increased to the tune of 19.51 per cent during 48th MW and 18.19 per cent during 52ndMW over the 42nd MW. The variety Dh-257 recorded significantly higher pod yield (3240 kg ha-1) and was at par withDh-256. The variety Dh-257 and Dh-256 recorded 83.56 and 83.39 per cent increased pod yield respectively, over TMV-2.The variety Dh-257 sown on 48th MW recorded significantly higher pod yield (3442 kg ha-1) and on par with Dh-257 sownon 52nd MW, Dh-256 sown on 48th MW and 52nd MW. The variety Dh-257 sown on 48th MW and 52nd MW recorded126.00 and 125.80 per cent higher pod yield compared to TMV-2 sown on 42nd MW respectively. Groundnut sown on 48thMW recorded significantly higher net returns (`105139 ha-1) and at par with 52nd MW compared to 42nd MW. The varietyDh-257 recorded significantly higher net returns (`131489 ha-1) and at par with Dh-256 compared to K-1574 and TMV-2.The variety Dh-257 sown on 48th MW recorded significantly higher net returns (`143423 ha-1) and on par with Dh-257sown on 52nd MW, Dh-256 sown on 48th MW and 52nd MW
