Influence of foliar nutrition of boron, zinc and biofertilizer on economics of cowpea [Vigna unguiculata (L.) Walp] under agroclimatic conditions of Chhattisgarh plains

The present study, titled “Influence of foliar nutrition of Boron, Zinc and Biofertilizer on Economics of Cowpea [Vigna unguiculata (L.) Walp] under agroclimatic conditions of Chhattisgarh plains.” was conducted during the rabi season of 2021-22. The experiment was carried out at the Krishi Vigyan Kendra farm in Raipur, which is situated in the central part of Chhattisgarh, an agro-climatic region known as the Chhattisgarh plains. Raipur lies at latitude 21.25° N and longitude 81.62° E, with an elevation of 289 meters above sea level. The study involved eight treatments: Rhizobium, Rhizobium + Boron at 0.2%, Rhizobium + Boron at 0.5%, Rhizobium + Zinc at 0.2%, Rhizobium + Zinc at 0.5%, Rhizobium + Boron + Zinc at 0.2%, Rhizobium + Boron + zinc at 0.5%, and a control treatment. The experiment was conducted using a Randomized Block Design with three replications. The highest total cost of cultivation (Rs118814/ha) was incurred under T4 {Rhizobium + Boron @ 0.5%}, maximum gross income of Rs 249700/ha was obtained with the Rhizobium + Boron + Zinc @ 0.5% (T8), maximum net return of Rs 131166/ha was obtained with treatment T8 and maximum benefit: cost ratio obtained with T8 (2.10).
