Impact on soil fertility status and concentration of nutrient (N, P and K) in grain by adopting nutrient management practices in rice crop (Oryza sativa L.) Under different establishment methods

Abstract

The present investigation was carried out to find the Impact on soil fertility status by adopting nutrient management practices in Rice Crop (Oryza Sativa L.) under different establishment methods. The experiment was conducted in A2 block at N. E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. The treatments consisting three establishment methods in main plots and five nutrient management practices in sub plots (fifteen combination) was laid out in split plot design (SPD) with three replications. The result revealed that, the concentration of nutrient (viz. N, P and K) in grain as well as in straw was affected significantly and was higher with transplanting method. Application of RDF(recommended dose of fertilizer)+5tFYM/ha exhibited statistically higher concentration and uptake, while RDF RDF(recommended dose of fertilizer) alone recorded significantly less concentration and uptake value of all nutrients. The status of available N, P and K in soil remained unaffected due to different establishment methods, however higher values were obtained in transplanting method with application of RDF+5tFYM/ha.
