Abstract:
The field experiment was conducted in a farmer’s field at salangapalayam village, Bhavani block of Erode district to study the effect of integrated nutrient management practices for yield maximization in irrigated transplanted ragi. The experimental plots were laid out in a randomized block design (RBD) with nine treatments and three replications. Among the various treatments implemented in this study, application of 100% RDF (60:30:30 kg of NPK ha^-1) + Soil application of Micronutrient mixture @ 12.5 kg ha^-1 (T₃) excelled over all other treatments and recorded higher values for the growth attributes viz., plant height (93.82 cm), leaf area index (4.43), days to fifty percent flowering (57 DAT), root length (14.70cm), root volume (36.52 cc), and dry matter production (8249.00 kg ha^-1) and yield attributes viz., number of tillers m^-2 (120.33), length of earhead (8.75), number of earheads m^-2 (114.02), number of fingers earhead^-1 (11.21), grain yield (3660 kg ha^-1) and straw yield (5616.72 kg ha^-1). Hence application of 100% RDF (60:30:30 kg of NPK ha^-1) + Soil application of Micronutrient mixture @ 12.5 kg ha^-1 (T₃) was noticed as a viable practice for achieving higher productivity and profitability in irrigated transplanted ragi.
