Abstract:
A field investigation on “Nutrient management through STCR equation in groundnut-potato cropping sequence” was carried out at Post Graduate Institute Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri (M.S.) during the year 2014-15 and 2015-16 to study production potential of groundnut– potato cropping sequence. The experiment was laid out in split plot design with three replications. The main plot comprised of six nutrient management treatments <em>viz., </em>STCR equation 20 q ha<sup>-1</sup> without FYM, STCR equation<em> </em>25 q ha<sup>-1</sup> without FYM, STCR equation 30 q ha<sup>-1</sup> without FYM, STCR equation 35 q ha<sup>-1</sup> without FYM, GRDF and RDF. Sub plot treatments consisted of three fertilizer levels <em>viz., </em>Control (No fertilizer), 75 per cent of RDF and 100 per cent RDF. The soil available nitrogen, phosphorous and potassium in soil after harvest of groundnut crop was not influenced significantly due to the different nutrient management treatments. GRDF recorded maximum available nitrogen (181.4 and 198.7 kg ha<sup>-1</sup>), phosphorous (20.00 and 21.37 kg ha<sup>-1</sup>) and potassium (426.7 and 434.8 kg ha<sup>-1</sup>) after harvest of groundnut crop during both the years, respectively. Mean available nitrogen (172.64 and 187.29 kg ha<sup>-1</sup>), phosphorous (19.21 and 20.79 kg ha<sup>-1</sup>) and potassium (394.4 and 408.3 kg ha<sup>-1</sup>) during 2014 and 2015 after harvest of potato crop during both the years. Application of GRDF recorded maximum available nitrogen (186.3 and 206.8 kg ha<sup>-1</sup>), phosphorous (20.5 and 22.4 kg ha<sup>-1</sup>) and potassium (433.0 and 442.8 kg ha<sup>-1</sup>) after harvest of potato crop during both the years. Application of 100 % RDF registered maximum available nitrogen (178.6 and 192.4 kg ha<sup>-1</sup>), phosphorous (19.9 and 21.3 kg ha<sup>-1</sup>) and potassium (399.6 and 412.6 kg ha<sup>-1</sup>) after harvest of potato crop during both the years.
