Evaluating the Impact of Phosphatic Fertilizers on Soil Nutrients and Morphological Traits of Wheat Varieties Under Field Conditions

This study addressed the challenge of phosphorus deficiency in calcareous soils, which limits crop productivity. A field experiment was conducted to evaluate the effects of phosphatic fertilizers, including DAP, NP, and SSP, applied at dose of 84 kg P ₂ O ₅ ha⁻¹, on soil nutrient dynamics and the morphological traits of three wheat varieties: TD-1, SKD-1, and TJ-83. For the experiment was utilized a randomized complete block design with treatments applied to soil and crops under controlled field conditions. Soil properties such N, P, K, EC, pH, and OM, along with wheat morphological traits, were assessed. The results indicate that DAP fertilizer significantly increased soil N and P levels, while SSP was more effective in enhancing soil K. SSP also increased soil EC, whereas pH decreased with all phosphatic fertilizers compared to the control. Among the wheat varieties, TJ-83 exhibited the highest grain yield (3049 kg ha⁻¹) with NP fertilizer. Notably, DAP improved the seed index and grain nutrient content compared to other treatments, with by 51.33g for TD-1 variety. These findings align with other studies report by the scientist, highlighting the efficacy of phosphatic fertilizers in improving soil fertility and crop traits under challenging soil conditions. This finding contributes to optimizing phosphorus fertilizer use for sustainable wheat production and emphasizes the need for long-term experiments integrating innovative amendments like biochar and nanotechnology to enhance soil health and crop productivity.
