Impact of Nutrient Management Technologies on Maize under Irrigated Conditions in Chandauli District, Uttar Pradesh

Abstract

The soil-test crop response (STCR) approach, which is currently gaining prominence for sustainable nutrient management, aims to adjust fertilizers for desired yield based on soil-test values.The STCR-based experiment was conducted for the desired maize production targets in alluvial soil of multiple locations of Persiya village in Naugharh block of Chandauli district, Uttar Pradesh during kharif 2019. It is important to test the developed fertilizer prescription equation to show how well technology is delivered to those who need it. A series of tests were set up in five locations in village Persiya to see how well fertilizer recommendations worked. First, the soils of the chosen area are examined for available N, P, and P. Control (T1), farmer behaviors (T2), the usually recommended fertilizer dosage (T3), and STCR-based fertilizer doses (T4 and T5) are among the treatments for yield targets of 30 and 35 q ha-1. The treatments were incorporated, cultivation procedures were followed on a consistent basis and yield of grains was recorded at harvest. The percentage increase in yield and benefit-cost ratio (B:C) were estimated using data on grain production and fertilizer dosages. The research findings revealed that the percent the accomplishment of the intended yield was within 10% fluctuation in all locations, showing the accuracy of the equations for prescribed integrated fertilizer dosages for maize. The highest percent increase in production was achieved in the yield of 35 q ha-1 (42.03%) followed by 30 q ha-1 (11.03%) beyond the prescribed fertilizer dosage (RDF). STCR 35 q ha-1 had the highest mean grain yield (3695.40 kg ha-1). STCR 35 q ha-1 had the highest benefit-cost ratio (3.76), followed by STCR 30 q ha-1 (3.46). The established maize fertilizer prescription equations may be advised for alluvial in eastern Uttar Pradesh in order to achieve a yield target of 35 q ha-1thereby resulting in greater economic yield. As a result, on tropical soils, an integrated STCR targeted yield method could prove to be the best feasible option for increasing maize productivity.
