Abstract:
The present experiment was conducted during 2018-19 and 2019-20 with three maize varieties (V₁: African Tall, V₂: J-1006; V₃: P-3396), varietal residual effects on oats cv. Kent and four nutrient management practices (N₀: Control; N₁: 100% RDF; N₂: 75% RDF + PGPR + Panchagavya spray; N₃: 50% RDF + 25% FYM + PGPR + Panchagavya spray) using split plot design. Results showed that different varieties could not show significant variations on fodder quality traits (Neutral detergent insoluble crude protein-NDICP, acid detergent insoluble crude protein-ADICP, acid insoluble ash, cellulose, hemi-cellulose and cell content). However, nutrient management practices showed significant variations on these parameters of maize. Integrated application of organic and inorganic nutrient sources (N₂: 75% RDF + PGPR + Panchagavya spray) showed significant lower NDICP, ADICP, acid insoluble ash, organic matter, cellulose and hemi-cellulose; and higher cell content as compared to control. Residual effect of fodder maize varieties could not show significant variations on quality traits of fodder oats. Among the nutrient management, the application of 75% RDF + PGPR + Panchagavya spray produced significantly lower NDICP and ADICP; and higher digestible energy (DE), total digestible nutrients (TDN), net energy for lactation (NEl) and relative feed quality (RFQ). System productivity was also not affected by main plot treatments; while, application of N₂ practice to both maize and oats significantly enhanced the dry matter, crude protein, ether extract and total ash yields compared with control and 100% RDF. Overall, it can be concluded that application of 75% RDF + PGPR + Panchagavya spray (N₂) is viable option to produce higher system productivity with better quality.
