SOIL TEST CROP RESPONSE CONCENTRATES ON COWPEA (VIGNA UNGUICULATA (L). WALP.) IN MOLLISOL OF UTTARAKHAND, INDIA

A field dissect was coordinated during spring 2009-2010 of each an Aquic hapludoll at the Norman E. Borlaug Crop Research Center of the G.B. Pant University of Agriculture and Technology, Pantnagar (290 N scope and 79 0 29' E longitude), as indicated by particular program of All India Coordinated Research Project on the earth test crop response relationship. The preliminary was coordinated in "two-phases". In the primary stage soil productivity tendency was made by detaching the test field into "three strips" and applying assessed doses of excrements in them (Strip I no fertilizer), Strip II (100, 100 and 100 kg/ha N, P2O5 and K2O/ha) independently, and strip III (200, 200 and 200 kg N, P2O5 and K2O) exclusively and creating of vapor crop Oat (Var. Kent). In the ensuing stage, for instance next season test crop Cowpea (var. Pant lobia-1) was created by secluding each strip into twenty-four plots having twenty-three fertilizer meds and one control plot. Response to "select" mixes of "three-levels" of FYM (0, 5 and 10 t/ha), "four-levels" of nitrogen (0, 15, 30 and 45 kg/ha), four degrees of phosphorus (0, 30, 60 and 90 kg/ha) and four degrees of potassium (0, 30, 60 and 90 kg/ha) at different readiness levels of cowpea was thought of. The estimations of the common carbon, Alkaline KMnO4 extractable N, Olsen's P and unprejudiced standard Ammonium Acetate extractable K in the test field went between 0.72-1.16 percent, 112.30-200.60 kg/ha, 13.00-24.24 kg/ha and 101.90-245.30 kg/ha, exclusively. In the current assessment indisputably, the straw yield ran from 13.07-24.94 q/ha and full-scale grain yield went from 9.00-18.20 q/ha. The enhancement needs for making of one quintal of cowpea grain was 5.71 kg of nitrogen, 0.90 kg of phosphorus and 3.72 kg of potassium. Percent duty of nitrogen, phosphorus and potassium was 62.00, 59.00 and 32.00 from soil, however from various sources as FYM was 7.00, 29.00, 10.00; engineered fertilizer 30.00, 14.00 and 30.00 and conjoint usage of substance excrement with FYM 30.00, 17.00 and 27.00 to the extent NPK exclusively. With the help of these data excrement proposition at different yield targets and soil test worth can be resolved. Coefficient of quadratic different backslide (R2) was found incredibly basic (0.898**) between grain yield, soil test regards, included fertilizers and FYM. Normal carbon, solvent KMnO4-N, Olsen's-P and AB DTPA and Ammonium acidic corrosive deduction K and AB DTPA K methods for available N, P and K separately were at standard for the cowpea created in Mollisol of Uttarakhand
