abstract
A field experiment was carried out at College farm, College of Agriculture, Navsari Agricultural University, Campus Bharuch during the kharif 2023 to study the effect of foliar nutrition in cowpea [Vigna unguiculata (L.) Walp.] under rainfed condition. The soil of experimental plot was clayey (Vertisols) with low in available N (240.42 kg/ha), medium in P2O5 (39.58 kg/ha) and high in K2O (338.28 kg/ha). The soil reaction (pH) was slightly alkaline (7.68). The experiment was arranged in a randomized block design (RBD) with nine treatments, which included: T1 (Control), T2 (RDF 20-40-00 NPK kg/ha), T3 (RDF + 2% Panchagavya), T4 (RDF + 2% Cow urine), T5 (RDF + 2% Vermi bed wash), T6 (RDF + 1% Novel), T7 (RDF + 2% Urea), T8 (RDF + 1% 19-19-19) and T9 (RDF + Nano urea 2 ml/lit). Foliar nutrition apllied at branching and flowering stages of cowpea. Result revealed that growth parameters viz. plant height at 60 DAS (71.33 cm) and at harvest (75.38 cm), number of branches/plant at 45 (8.65) and 60 DAS (9.64), dry matter accumulation/plant at 45 DAS (20.80 g) and at harvest (32.24 g), yield attributes viz. number of pods/plant (25.55), number of seeds/pod (17.41) and length of pod (18.24 cm) as well as seed yield (1625 kg/ha) and stover yield (3004 kg/ha), quality parameter including protein yield (354.61 kg/ha) recorded significantly the highest with T6 (RDF + 1% Novel), which was statistically at par with T3 (RDF + 2% Panchagavya) and T8 (RDF + 1% 19-19-19).
