ABSTRACT
In Tunga Bhadra project irrigation command, India, during summer the study on response of rice genotypes (GGV 0501, RNR 15048 and BPT 5204) to levels of seed rates (25, 30 and 35 kg ha-1) and micronutrients (control, FeSO4 (Soil @ 25 kg ha-1+ foliar @ 0.5% twice at 15 and 30 DAS), ZnSO4 (Soil @ 25 kg ha-1+ foliar @ 0.5% twice at 15 and 30 DAS), FeSO4 + ZnSO4 (each to soil @ 25 kg ha-1 + foliar @ 0.5% at 15 and 30 DAS)) under drill sown conditions revealed significantly higher productive tillers m-2 (411.5), filled grains per panicle (151.5) and lower sterility percentage (3.5) with cv. GGV 0501 sown using medium seed rate of 30 kg ha-1 and supplied with FeSO4 and ZnSO4 both to soil and to the foliage. Similar was the trend in grain (6.27 t ha-1) and straw (8.24 t ha-1) yields. The treatment also recorded higher kernel protein (8.11%) closely followed by the same cultivar and seed rate but supplied with only ZnSO4. The lowest grain yield (3.51 t ha-1) was recorded with cv. RNR 15048 while kernel protein content (6.36%) was observed with cv. BPT 5204 both sown using lower seed rate of 25 kg ha-1 and not supplied with any micronutrient. Consequent upon higher grain yield, cv. GGV 0501 sown using medium seed rate of 30 kg ha-1 and supplied with FeSO4 and ZnSO4 both to soil and to the foliage registered higher gross (` 135745 ha-1) and net (` 81969) returns and B:C (2.52) among all.
