Abstract:
A field experiment was conducted to determine the effect of different levels of Nitrogen and Phosphorus without and with Rhizobium Inoculaton on Growth and Yield of Blackgram (var. SHEKAR- II) with 9 treatments in the Zaid 2021 with different levels of nitrogen (15 and 25 kg/ha), phosphorus (35 and 45 kg/ha) without and with Rhizobium inoculation (20g/kg of seed), respectively at crop research farm, department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, Uttar Pradesh. The soil of experimental plot was sandy loam in texture, basic in soil reaction (pH 7.7), low in organic carbon (0.48%), available N (278.93 kg/ha), available P (14.1 kg/ha), available K (213.4kg/ha). The experiment was laid out in Randomized Block Design with nine treatments and each treatment replicated thrice. Maximum plant height (52.42 cm), branches/plant (8.80), plant dry weight (12.70 g/plant), pod/plants (40.80), seeds/pod (7.80), seed yield (847 kg/ha), stover yield (3566.33 kg/ha), biological yield (4413.33kg/ha), and test weight (37.21g) were recorded with application of 25kg N/ha + 45kg P/ha + 20kg K/ha + Rhizobium (20g/kg of seed). Higher Gross returns (53361Rs./ha), Net returns (32802.2Rs./ha) and Benefit Cost Ratio (2.59) were also recorded in the same treatment.
