Impact of intercropping on productivity and economic evaluation of Bhringraj (Eclipta alba) under Psidium guajava based agroforestry system

Abstract

The current research entitled "Impact of Intercropping on Growth and Productivity on BHRINGRAJ (Eclipta alba) Under Psidium guajava Based Agroforestry System at Kanker" was conducted during 2024-25 at Krishi Vigyan Kendra Kanker. The experiment was conducted using a Randomized Block Design (RBD) with eight treatments and three replications. The test plots were established within a mature Psidium guajava plantation. Each plot measured 2 x 3 meters, and plots designated for intercropping (T1-T7) were designed to have an equal number of trees, ensuring consistent shade and resource competition across treatments. The maximum fresh biomass yield was recorded in T8 (100% RDF without tree) with 25.45 t ha-1year-1, which was significantly higher than all other treatments. Among all the treatments, T6 (100% Mahua cake) had the greatest economic return, with a net return of ₹ 1,55,000 ha-1 from Bhringraj only and ₹ 2,75,000 ha-1 when planted along with guava, having a high B:C ratio of 4.50.The enhanced economic performance is contributed by the excellent yield potential of Mahua cake (8.6 t ha-1), low cost of inputs (₹ 60,000 ha-1), and synergy with guava plants, thereby being the most economical organic treatment in the agroforestry system. The maximum gross return (₹ 2,40,000 ha-1) and net return (₹ 1,87,000 ha-1) were obtained by T8 (RDF without tree) because of its highest yield (9.6 t ha-1). No guava returns, however, were accrued under this system.
