Abstract:
An agronomic study on cowpea growth and yield impacted by PGRs and foliar nutrition was carried out in a field experiment at the College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari, during the 2021 kharif season. The experimental plot's soil had a clayey texture and an alkaline reaction. Eight treatment were tested in this experiment using a Randomized Block Design with three replications. The foliar spray of 2% urea at 35 and 50 DAS significantly influenced all the cowpea growth and yield parameters, including plant height, number of branches/plant, number of nodules/plant, pod length, number of pods/plant, number of seeds/pod, and seed and haulm yield. It was found to be statistically comparable to T4 (foliar spray of Pulse Wonder fertilizer at 5 kg/ha) and T2 (foliar spray of 1% Novel). Treatment T3 (2% Urea Foliar Spray) yielded the highest net return of 46659 ₹/ha. Treatments T4 (42215 ₹/ha) and T2 (40162 ₹/ha) came in second and third, respectively. Treatment T3 produced the greatest BC ratio (2.97), which was followed by treatments T4 (2.71) and T2 (2.64). Based on the results of a year-long experiment, it can be concluded that full doses of RDF (20:40:00 NPK kg/ha) should be used to grow kharif cowpea, along with foliar sprays of 2% urea or 5% Pulse Wonder fertilizer or 1% Novel (Nauroji organic product) at 35 and 50 DAS to increase yield and financial returns.
