tailieunhanh - Soil test crop response studies on cowpea (Vigna unguiculata (L). Walp.) in Mollisol of Uttarakhand, India

A field experiment was conducted during spring 2009-2010 in a Aquic hapludoll at the Norman E. Borlaug Crop Research Centre of the . 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 Oat (Var. Kent). In the second phase, . next season test crop Cowpea (var. Pant lobia-1) was grown by dividing each strip into twentyfour plots having twenty-three fertilizer treatments and one control plot. Response to “select” combinations of “three-levels” of FYM (0, 5 and 10 t/ha), “four-levels” of nitrogen (0, 15, 30 and 45 kg/ha), four levels of phosphorus (0, 30, 60 and 90 kg/ha) and four levels of potassium (0, 30, 60 and 90 kg/ha) at different fertility levels of cowpea was studied. | Soil test crop response studies on cowpea (Vigna unguiculata (L).
