Effect of Different Organic and Inorganic Fertility Sources on Protein Content in Pearl Millet Crop Grown in Sandy Soils

A field experiment carried out at the S.K.N. College of Agriculture, Jobner, Agronomy farm. The six treatments include four levels of liquid organic manures (control, panchgavya, vermiwash, and cow urine), which are given to the main and sub plots, respectively, and are replicated three times in the Split Plot Design. The integrated nitrogen management treatments include control, 100% RDN, 75% RDN + 25% N through FYM, 50% RDN + 50% N through FYM, 25% RDN + 75% N through FYM, and 100% N through FYM. As a test crop, the pearl millet variety "RHB 223" was used. The findings showed that integrated nitrogen management improved the performance of the pearl millet crop before having a residual effect on the mustard variety Giriraj (DRMR IJ-31). In addition to improved soil health in terms of physical and chemical properties, coordinated nitrogen management significantly raised soil organic carbon and improved crop routine. The application of 25% RDN + 75% N through FYM to pearl millet and 50% RDN + 50% N through FYM to mustard crop, among other treatments, had a residual effect that improved crop performance and quality content while also enhancing the physico-chemical properties of the soil. These methods demonstrate a viable approach to enhancing soil nutrient availability on a sustainable basis.
