Effect of pruning and sources of nutrient on growth and yield of rice under D. sissoo

Abstract

This study evaluated the effects of D. sissoo pruning and sources of nutrient, including VAM and fulvic acid, on rice (Oryza sativa L JR-206) growth and yield, during Kharif 2023–2024 at JNKVV, Jabalpur. A strip plot design with five pruning levels (P0-without pruning to P3–75% and Open-without tree) and four nutrient treatments (T0-100% RDF to T3–50% RDF + VAM + soil-applied fulvic acid + 2 foliar sprays) was replicated three times. Maximum rice height (98.4 cm) and panicle length (26.3 cm) occurred under open conditions, while effective tillers (430.4) and panicle weight (7.93 g) were highest under 75% pruning. Grain and straw yields were maximized under 75% pruning and T2 nutrient treatments.
