Effect of Spacing and Banana Pseudo stem-Based Nutrients on Cowpea Yield under Agroforestry

The present investigation was carried out to check the effect of various spacings and foliar sprays of Novel (banana pseudo stem based organic liquid nutrients) on growth and yield of cowpea (Vigna ungiculata L.) under mango-based agroforestry system during 2021 and 2022 at Navsari Agricultural University, Navsari, India. The trial was framed with eight treatment combinations of two factors viz., two levels of spacing and four levels of foliar spray of banana pseudo stem based organic liquid nutrients under mango orchard and open condition. The closer spacing (S1: 30 cm x 30 cm) recorded significantly maximum plant height of cowpea at harvest. However, the highest f collar diameter, number of branches per plant, number of clusters per plant, yield per plant, plot and hectare were observed with spacing 45 cm x 45 cm as compared to 30 cm x 30 cm under mango-based agroforestry system as well as in open condition. Among various foliar application of novel fertilizers, Novel plus containing banana pseudo stem based organic liquid nutrients + botanical pesticides @ 1 % recorded significantly maximum cowpea growth parameters (plant height, collar diameter and number of branches per plant) as well as yield parameters (number of clusters per plant, and yield per hectare).
