Abstract:
A field experiment was conducted during Rabi 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P.). The soil of experimental plot was sandy loam in texture, nearly slightly acidic in soil reaction (pH 7.3), low in organic carbon (0.186%), available N (88.35%), available P (13.7 kg/ha), available K (235.2 kg/ha).The experiment was consisted of 9 treatments each replicated three times. The experiment was laid out in Randomized Block Design. The result showed significant increase in plant height (68.09 cm), number of nodules/plant (34.89), dry weight (15.97 g), crop growth rate (17.35 g/m²/plant) with application of 40 kg P/ha which was sown on November 16 and whereas maximum relative growth rate (0.058g/g/day) was recorded in T₅(30 kg/ha P +26^th November 2020) respectively. Number of pods/plant (29.80), number of seeds/pod (1.67), Seed index (15.20 g), Seed yield (2183.33 kg/ha), Stover yield (4266.67 kg/ha), Harvest index (38.25%) significantly increased with application of 40 kg P/ha which was sown on November 16. Gross return (Rs.72099.9/ha), net return (Rs.52602.14/ha) and B:C ratio (2.69) were found significantly highest with application of 40 kg/ha P + 16^th November 2020.
