Abstract
A field experiment was conducted during Kharif season 2019 to know the effect of different fertility levels on growth and yield attributing characters of cowpea (Vigna unguiculata L. Walp var. Kashi Kanchan). Data revealed that higher growth and yield parameters were recorded under the treatment (T2) 150% RDF i.e. plant height (97.26 cm), branches number (7.5), leaves number (30.67), pod number per cluster (3.6), pod number per plant (14.43), pod length (22.7cm), yield of pod per plot (3.18 kg), pod yield in (q/ha) (66.41 q/ha). The nutrient application of NP0K (T5) was most effective for higher pericarp weight (3.08g). The restricted nitrogenous fertilizer application was most appreciated for nodule count at the time of harvesting of the crop 18.8 nodules/plant. Higher protein content in 150% RDF T2 (28.3%). B:C ratio is an important parameter to understand the economics of any treatment among the treatments evaluated, application of 50% RDF (T3) was most impressive with higher B:C ratio (5.58) followed by 100% RDF (T1) with (5.52).
