Analysis of monetary input output in Dalbergia sissoo Roxb. based agroforestry system under different pruning and nutrient management

Abstract

A field investigation was carried out at the Agroforestry Research Farm, Department of Forestry, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, in Jabalpur, Madhya Pradesh. The aim of this study was to find out the economical viable treatment during two Rabi season consecutive years of 2022-23 and 2024. An experiment was laid out in a split plot design with three replications of two systems: Pruning level (0, 25, 50 and 75% intensity) and open system (no tree only flower). Seven sub plot treatment 6 IMN (T1 - Green manuring with dhaincha, T2 - Green manuring +Trichoderma, T3 - Enriched vermicompost @ 2th-1(VAM + Trichoderma + Azospirilium), T4 - Vermicompost without enriched@ 2t ha-1, T5 -Green manuring+ Enriched vermicompost @2 t-1, T6 - Green manuring +Vermicompost without enriched @ 2 t ha-1 and T7 control (RDF). Higher net monetary return was recorded under 75% pruning + T5 Green manuring+ Enriched vermicompost @2 t-1 (Rs 221261/ ha) followed by open condition (Rs217720/ha), 50% pruning (Rs 209215/ ha) and 25% pruning (Rs 200932/ha) and lowest in no pruning + Green manuring with dhaincha (Rs 147150/ha).
