SOIL TEST BASED FERTILIZATION RECOMMENDATIONS OF ECONOMICS AND NUTRIENT COMPOSITION OF MUSTARD ON INCEPTISOL
Journal of Experimental Biology and Agricultural Sciences
During the winter (Rabi) season of 2019-20, the experiment was conducted in a farmer's field in the village of Loharapur, Varanasi, to investigate the impact of nutrient management technologies in alluvial soil with farmyard manure and various levels of inorganic fertilizers under mustard (Brassica juncea L.). Based on the STCR target yield idea, the use of plant nutrients has achieved mustard (18.0 q ha-1) and (22.0 q ha-1) outputs (soil test crop response technology). The test results
... d that the target yields were reached within + 5% of site modifications, confirming the validity of the formulae used to prescribe integrated mortar fertilizer dosages. For RDF, the highest production increases of 22 q ha-1 (37, 60%), followed by 18 q ha-1 were recorded (12.05 percent). The maximum cost-effectiveness and profit rate of 22.00 q ha-1 was the result. Organic carbon content is positive and significantly connected to the activity of the enzyme. As a consequence, the combination of NPK and FYM has been more successful in improving the productivity of rice aimed at 18 q ha-1, 22 q ha-1, and soil nutritional status than a single application of FYM or chemical fertilizer. Significant net benefits of mustard at the site (Rs 55,190.00 and Rs 38,583.00) in the treatment of plant nutrient levels in the soil test; (STCR treatment). Though fertilization enhanced mustard production above control, it was reported that using NPK and FYM together was more successful than using them alone in increasing mustard productivity.
