 ABSTRACT

The field experiment was conducted during kharif season of 2016 on deep black soil at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, India. The study included 36 hybrids (nine early, 24 medium, and three late maturing type) and were laid out using Randomised Complete Block Design replicated twice. The detailed plant phenology and final grain yield were recorded for all the hybrids and statistically analysed for comparison and to record potential yield. Among the three maturity groups of hybrids the maximum days taken for 50 % anthesis was recorded by hybrids DMH-1 (55 DAS), GH-15305 (59 DAS) and DKC-9141 (63 DAS), while days taken to physiological maturity was recorded by the hybrids GH-1316 (109 DAS), GK-3150 (119 DAS) and DKC-9141 (125 DAS) in early, medium, and late maturing hybrids, respectively. The mean grain yield of these maturity groups were 7550, 9342 and 11050 kg ha-1, respectively, thus indicating that late maturing hybrids give the highest yield under potential management condition followed by medium and the lowest by early maturing hybrids.
