Abstract:
An investigation was undertaken at Student Farm, CCS Haryana Agricultural University Hisar, Haryana (spring 2020) in split plot design to compute yield, quality, economics, N, P and K uptake by grain and straw of maize (Zea mays L.). There were two single cross hybrid (SCH) of maize and two irrigation source (IS) in main plots while four levels of organic manure (M) in subplots, each replicated thrice. Grain yield, protein content in grain, N, P and K uptake by grain and straw were recorded significantly higher by HQPM-1. Similarly, treated sewage water recorded significantly higher values of protein content in grain, N, P and K uptake by grain and straw, grain yield of maize. Interaction of SCH and I on grain yield were significant. HQPM-1 with treated sewage water recorded highest grain yield. Among organic manures, 100% RDN through vermicompost achieved higher quality content, yield, N, P and K uptake by grain and straw of maize. The interaction of SCH and M was found significant and HQPM-1 with 100% VC resulted highest grain yield. Overall, our results suggests that treated sewage water can be a potential replace to conventional water sources and 100% RDN through vermicompost can enhance the quality, yield, nutrient uptake in maize. However, higher economics was recorded under 100% RDN through FYM.
