| dc.description.abstract | A field experiment was conducted during the year 2016-17 in an Aquic Hapludoll at D7 block of Norman E. Borlaug Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar under AICRP on soil test crop response correlation to develop fertilizer adjustment equation for computing nutrient doses for target yield of finger millet on the basis of initial soil fertility. Response of finger millet to selected combination of three levels of FYM (0, 5 and 10 t ha-1), four levels of nitrogen (0, 20, 40 and 60 kg ha-1), four levels of phosphorus (0, 10, 20 and 30 kg P2O5 ha-1) and four levels of potassium (0, 10, 20 and 30 kg K2O ha-1) of finger millet at different fertility levels was studied. Chemical analysis was carried out to estimate organic carbon, available nitrogen, phosphorus and potassium in soil. Nutrient requirement to produce one quintal of finger millet grain was found to be 1.78 kg, 0.40 kg, and 2.37 kg of N, P and K, respectively. Percent contribution of N, P and K was 28.05, 69.82 and 44.59 from soil and 21.84, 4.56 and 56.84 from FYM, 73.76, 74.30 and 81.86 from chemical fertilizer and 80.79, 82.10 and 83.82 from combined use of chemical fertilizer with FYM. Fertilizer adjustment equations were developed with and without FYM with the help of basic data. Coefficient of determination (R2) was found highly significant (0.896**) between fruit yield, soil test values, added fertilizers and interaction between soil and fertilizer. Suitability of soil test methods was also evaluated by R2 value of multiple regression equation and concluded that organic carbon or alkaline KMnO4 , Olsen’s and Normal neutral NH4OAC methods are suitable for the determination of available nitrogen, phosphorus and potassium , respectively for finger millet crop grown on Mollisol of Uttarakhand. Findings could be used as guide for efficient fertilizer management for finger millet grown in Mollisol of Uttarakhand, which provides not only balanced nutrition to crop but also may fetch good profitability. | en_US |
