Influence of Weather on Groundnut Genotypes under Extended Sowing Window during Kharif Season

Abstract

A field experiment was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during the year 2018. The experiment was laid out in split plot design consist of four sowing window as main plots i.e., June 1st fortnight, June 2nd fortnight, July 1st fortnight and July 2nd fortnight and four groundnut genotypes as sub plots i.e., GPBD-4, G2-52, Dh-245 and JL-1085 with three replications. The groundnut crop sown during first fortnight of June recorded significantly higher pod yield (3,551 kg ha-1) and haulm yield (4,477 kg ha-1) compared to second fortnight of July and was at par with first fortnight of July and second fortnight of June. Among groundnut genotypes, G2-52 recorded significantly higher pod yield (3,364 kg ha-1) and haulm yield (4,239 kg ha-1) over JL-1085 and was on far with Dh-245 and GPBD-4. The groundnut genotype, G2-52 sown during first fortnight of June recorded higher pod yield (3,841 kg ha-1) and haulm yield (4,840 kg ha-1) compared to JL-1085 sown during second fortnight of July.
