Effect of Nitrogen and Phosphorus Fertilization on the Growth and Yield of Wheat (Triticum aestivum L.)

Abstract

A field trial was carried out as an experiment during the Rabi season of 2022–23 at the farm of R.M.P. (P.G.) College Gurukul–Narsan, Haridwar (U.K.) to identify optimum Nitrogen and phosphorus fertilizers rates. Sand loam soil with a pH of 7.5, electrical conductivity (EC) of 0.26 dSm-1, organic carbon content of 0.60 percent, and available nutrients at levels of 217.0, 19.66, and 196.66 kg ha-1 for nitrogen (N), phosphorus (P), and potassium (K), respectively, was used for the experiment. Uttar Pradesh. "Effect of Nitrogen and Phosphorus Fertilization on the Growth and Yield of Wheat (Triticum aestivum L.)" was the main topic of the study. The common dosage for the experimental design was 40 kg N + 80 kg. P2O5 was administered to every treatment. The experiment was designed using a Randomized Block Design (RBD) with 12 treatments spread across three replications, along with a control group. Based on the results, it was found that the mixture of 40 kg/ha P2O5 and 50 kg/ha (N) significantly improved yield, growth, and other yield parameters. The data for treatment 5 showed the highest values for the following parameters: plant height (97.62 cm),), number of tillers m-2 (375.00), dry matter accumulation (16.53 g /plant), test weight (44.99g, grains /ear (12.93), effective ear head per (m-2) (282.66), and straw yield (47.59 quintals/ha).
