Effect of spacing and foliar spray of novel (banana pseudostem-based organic liquid nutrients) on cowpea (Vigna unguiculata) production under mango-based agroforestry system

The study was undertaken to check economic possibility of cowpea [Vigna unguiculata (L.) Walp.] under mango-based agroforestry system with various spacings and foliar sprays of novel (banana pseudostem - based organic liquid nutrients) during 2021-22 at ASPEE College of Horticulture, Navsari Agricultural University, Navsari, Gujarat, India. The trial was framed with eight treatment combinations of two factors which contain two levels of spacings and four foliar sprays of fertilizers (after initiation of flowering and 15 days after first spray) under mango orchard and open growing condition in a randomized block design with factorial concept consisting of three replications. Under mango-based agroforestry system and in open condition, highest net realization (₹ 1,57,437/ha and ₹ 1,89,259/ha, respectively) and BCR (2.58 and 1.98, respectively) were obtained in S2F4 [45 cm × 45 cm spacing and novel plus (banana pseudostem - based organic liquid nutrients + botanical pesticides) sprayed at 1 %].
