EFFECT OF NITROGEN AND PHOSPHORUS LEVELS ON PRODUCTIVITY AND PROFITABILITY OF FODDER MAIZE (ZEA MAYS L.)Mallikarjun, Abhinandan Singh, Phool Singh Hindoriya, Awadhesh Kishore and Jaidev SharmaAbstract A field experiment entitled âEffect of Nitrogen and Phosphorus Levels on productivity and profitability of Fodder Maize (Zea mays L.)â was conducted at the Crop research centre-1, School of Agriculture, ITM University Gwalior (M.P.) during the Kharif season 2022. The experiment was laid out in a Factorial randomized block design with 9 treatment combinations, which includes three Nitrogen Levels (viz., N1-30 kg N/ha, N2-60 kg N/ha and N3-90 kg N/ha), three phosphorous levels (viz., P1-20 kg P2O5/ha, P2-40 kg P2O5/ha and P3-60 kg P2O5/ha) and one absolute control, and each treatment were replicated thrice. The result of the experiment revealed that an increase in the application of Nitrogen and Phosphorous had significantly increased the growth, yield nutrient uptake, quality and economics of fodder maize viz., plant height (cm), No. of leaves per plant, leaf area index, Stem diameter (cm), Leaf stem ratio, green fodder yield, dry matter content, dry fodder yield, nutrient uptake (kg ha-1), quality studies and economics of fodder Maize, the application of 90 kg N/ha and 60 kg P2O5ha-1 were significantly superior over the application of 30 kg N/ha and 20 kg P2O5/ha and application of 60 kg N/ha and 40 kg P2O5 ha-1 were found significant with this treatment. |
