Economic perspective of integrated nitrogen management under teak (Tectona grandis L.F.) - Okra (Abelmoschus esculentus L.) based Silvi-Horticulture System

Aim of present study to assess the profitable agroforestry model and economically best INM treatments under Teak based silvi-horticulture system for Okra. A field experiment was conducted during the year 2019 and 2020 in summer season. Okra (Abelmoschus esculentus L.) cv. GAO- 5 was sown in the inter spaces of 23-years old plantation of Tectona grandis planted at a spacing of 3m x 2m and applied the different integrated nitrogen management (INM) treatments under the teak and in open condition. The trial was framed with eleven treatments under teak plantation and open condition in Randomized Block Design (RBD) consisting of three replications. From the calculation of economics of experiment the result emerged that when only sole okra crop yield considered in economic estimation the highest net realization (?2,17,022 ha⁻¹) was recorded in T,,: 75% RDN through Neem coated urea + 25% RDN through Vermicompost in open field while benefit cost ratio was recorded highest in T₁₀ 100% RDF in open condition (2.61). Whereas, the lower net realization and BCR of okra were registered under teak-okra based silvi-horticulture system as compared to sole crop. However, if we considered the yield of both okra as intercrop with teak the highest net realization and BCR (? 5,05,797 and 6.95, respectively) were recorded in T₅: 75% RDN through Neem coated urea + 25% RDN through Vermicompost under teak-okra based silvi-horticulture system.
