Abstract

The studies on STCR-IPNS for desired yield targets were conducted on Greengram crop at farmer field during 2022-2023 climate on an Alfisol of Tamil Nadu to verify the fertilizer prescription models over the available technology and to analyze the economics of the adoption of these models to enhance the productivity and profitability of the crop greengram. The treatments include control, blanket recommendation (100% RDF), blanket recommendation (NPK+FYM @ 12.5t ha-1), soil test crop response (STCR) based fertilizer dose for a yield target of 0.8, 1.0 and 1.2 t ha-1, STCR-IPNS based fertilizer dose for an yield target of 0.8, 1.0 and 1.2 t ha-1and farmer’s practice. The N, P and K fertilizer for different targets was calculated based on the initial soil test values of the respective locations. The cultivation practices were carried out periodically and the grain yield was recorded at harvest. Using the data on grain yield and fertilizer doses applied, parameters viz., per cent achievement, and response ratio (RR) were computed. The results revealed that the targeted yield has been achieved within +/-10 per cent variation proving the validity of the equations.
