Abstract:
A field experiment was carried out to evaluate the performance of pre-released finger millet genotypes at different fertility levels under irrigated condition. This experiment was conducted during kharif 2022 at Zonal Agricultural Research Station, Mandya district. The experiment was laid out in split plot design with four fertility levels as main plot treatments 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 and four varieties as sub plot treatments viz., V₁- PR-1731, V₂- GPU-67, V₃- VL-376 and V₄- PR-202 replicated thrice. Among the different fertilizers levels, application of 125 per cent RDF recorded significantly higher grain and straw yield (3005 and 6173 kg ha^-1, respectively) as compared to absolute control Among the finger millet genotypes tested, PR-1731 variety recorded significantly higher grain and straw yield, respectively as compared to other check varieties. Among the finger millet genotypes tested, PR-1731 variety recorded significantly higher nutrient uptake of N, P and K by grain and straw as compared to other check varieties. The data on economics indicated that among the different genotypes evaluated higher gross returns (Rs.60509 ha^-1), net returns (Rs.17380 ha^-1) and B: C ratio (1.37) was obtained with PR-1731 variety as compared to other check varieties. Between the different fertility levels tested higher gross returns (Rs. 70370 ha^-1), net returns (Rs. 23860 ha^-1) and B: C ratio of 1.51 was obtained with application of 125 per cent of recommended dose of fertilizers. From the present investigation it was clear that, the finger millet variety PR-1731 has responded to application of 125 per cent of RDF.
