Abstract:
A field experiment to study the performance of pre-released finger millet genotypes as influenced by different fertility levels under irrigated condition was conducted during Kharif 2020 at Zonal Agricultural Research Station, Mandya district. The experiment was laid out in split plot design with four fertility levels viz., F0-Absolute control F1- 75 per cent of recommended dose of fertilizers (RDF), F2- 100 per cent RDF and F3- 125 per cent RDF as main plot treatments and three varieties namely, V1- KMR-316, V2 KMR-630 and V3 - KMR-701 as sub plot treatments, with three replications. Among the Finger millet genotypes tested, significantly higher grain yield (4298 kg ha-1) and straw yield (6266 kg ha-1) was recorded with KMR-316 when compared to KMR- 630 (3716 kg ha-1 and 5557 kg ha-1, respectively). Among the fertility levels, application of 125 per cent RDF recorded significantly higher grain yield (4205 kg ha-1), Straw yield (6107 kg ha-1) as compared to Absolute control. However, on par yields were observed with application of 100 per cent of recommended dose of fertilizers. The data on economics indicated that among the different genotypes evaluated higher gross returns (Rs.151660 ha-1), net returns (Rs.104390 ha-1) and B: C ratio (3.20) was obtained with KMR-316 finger millet variety as compared to check variety. Between the different fertility levels tested higher gross returns (Rs. 148278 ha-1), net returns (Rs. 98493 ha-1) were obtained with application of 125 per cent of recommended dose of fertilizers whereas higher B: C ratio (3.20) was obtained with application of 100 per cent of recommended dose of fertilizers. From the present investigation it is clear that, cultivation of KMR - 316 is found to be economically feasible when 100 per cent of RDF is used for its cultivation.
