Response of Summer Forage Cowpea (Vigna unguiculata L.) to Spacing and Seed Rate

A field experiment on “Response of summer forage cowpea (Vigna unguiculata L.) to spacing and seed rate” was carried out during summer 2022 on loamy sand soil of Agronomy Instructional Farm, C. P. College of Agriculture, SardarkrushinagarDantiwada Agricultural University, Sardarkrushinagar. The experiment was laid out in split plot design with four replications. The result revealed that significantly the highest plant height was recorded under the line sowing at 30 cm. Higher numbers of branches per plant and leaf area per plant were observed under the line sowing at 45 cm. Cowpea sown at narrow row line sowing at 30 cm produced significantly the highest green forage and dry forage yield. The maximum net realization and benefit cost ratio were recoded under the line sowing at 30 cm. Seed rate of 50 kg/ha recorded significantly higher plant population and plant height. Higher number of branches per plant and leaf area per plant were recorded with seed rate of 30 kg/ha. Higher green forage and dry forage yield were recorded under seed rate of 50 kg/ha. The maximum net realization was accured with the seed rate of 50 kg/ha. The maximum benefit cost ratio was accured with the seed rate of 40 kg/ha.
