| dc.description.abstract | A field experiment was conducted during Rabi 2006-07 at Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar in clay loam soil classified as a Aquic Hapludoll. The test crop yellow sarson was grown using 3 levels of N (60, 90 and 120 kg ha-1), P (20,40 and 60 kg ha-1) and K (20,40 and 60 kg ha-1) with controls in already created fertility. Three different fertility gradient strips with 24 treatments were randomly distributed in each strip having 3 blocks made of differing in organic manure level (0 t ha-1, 5 t ha-1, 10 t ha-1). Chemical analysis was carried out to estimate organic carbon, available N, P and K in soil. Multiple regression analysis of data was done by selected soil test methods combination for evaluation of soil test methods and to study pattern of yield response to the application of FYM and fertilizer N, P and K at different soil fertility levels. It was found that Organic Carbon, Olsen’s P, Ammonium Acetate K and AB-DTPA methods are equally suitable in soil testing laboratories for determining N, P and K availability to yellow sarson grown on Mollisol of Tarai region of Uttarakhand. The values of the organic carbon, Alkaline KMnO4 N, Olsen’s P and NAmmonium Acetate K in the experimental soil ranged between 0.57-1.54 percent, 119.2 - 228.92 kg ha-1 and 17.8-59.0 kg ha-1, 151.9- 343.1 kg ha-1, respectively. The uptake of N, P and K ranged between 42.0-126.4, 11.0-32.9 and 27.9-101.3 kg ha-1 by yellow sarson, respectively .The grain yield ranged from 10.4- 21.6 q ha-1 in the present investigation. The nutrient requirement for producing one quintal of yellow sarson grain was found to be 5.08 kg of nitrogen, 1.24 kg of phosphorus and 3.96 kg of potassium. Percent contribution of nitrogen, phosphorus and potassium was 33.89, 52.99 and 16.38, respectively from soil. 52.35, 16.41 and 40.66, respectively, from FYM, 30.00, 50.68 and 96.02 respectively from chemical fertilizer and 32.50, 51.50 and 101.95, respectively from conjoint use of chemical fertilizer with FYM. The quality parameters are judged by estimating, oil content ranged from 34.9 - 48.6 % and protein content ranged from 14.7 – 24.2 %. Coefficient of regression (R2) was found highly significant (0.676**) between yield and soil test values, added fertilizers and interaction between soil and fertilizer. These findings can successfully be used in the larger parts of Tarai region of Uttarakhand as effective guide for efficient balanced fertilization of nutrients for yellow sarson. | en_US |
