Abstract:

A field experiment was conducted during spring 2014-2015 at the Norman E. Borlaug Crop Research Centre of the G.B. Pant University of Agriculture and Technology, Pantnagar (290 N latitude and 79 0 29’ E longitude), as per technical programme of All India Coordinated Research Project on the soil test crop response correlation. The experiment was conducted in “two-phases”. In the first phase soil fertility gradient was developed by dividing the experimental field into “three strips” and applying graded doses of fertilizers in them (Strip I no fertilizer), Strip II (100, 100 and 100 kg/ha N, P2O5 and K2O/ha) respectively, and strip III (200, 200 and 200 kg N, P2O5 and K2O) respectively and growing of exhaust crop sorghum (var. Pant Chari-7). In the second phase, i.e. next season test crop Urd (var. Pant Urd-7) was grown. Response to “select” combinations of “three-levels” of FYM (0, 5 and 10 t/ha), “four-levels” of nitrogen (0, 10, 20 and 30 kg/ha), four levels of phosphorus (0, 20, 40 and 60 kg/ha) and four levels of potassium (0, 30, 60 and 90 kg/ha) at different fertility levels of Urd bean was studied. The values of the organic carbon, Alkaline KMnO4 extractable N, Olsen’s P and Neutral normal ammonium acetate extractable K in the experimental field ranged between 0.22-0.75 per cent, 112-178 kg/ha, 12.20-20.02 kg/ha and 100.2-178.85 kg/ha, respectively. In the present investigation the total straw yield ranged from 64.93-233.76 q/ha and total grain yield ranged from 17.26-181.72q/ha. The nutrient requirement for production of one quintal of Urd bean grain was found to be 3.18 kg of nitrogen, 0.63 kg of phosphorus and 2.54 kg of potassium. The percent contribution of nitrogen, phosphorus and potassium was 38.15, 72.61 and 36.51, from soil, whereas from other sources as FYM was 78.34, 17.05, 38.21; chemical fertilizer 169.81, 17.19 and 94.98 and conjoint use of chemical fertilizer with FYM 187.65, 15.88 and 96.08 concerning NPK respectively. With the help of these data fertilizer recommendations at different yield targets and soil test value can be calculated. Findings from present study can successfully be utilized for the larger parts of Tarai region of Uttarakhand as an effective guide for efficient and balanced fertilizer recommendations.
