Effect of organic and inorganic fertilizers on growth and yield of sesame (Sesamum indicum) under Indian rosewood (Dalbergia sissoo) based agroforestry in Chhattisgarh plain

Abstract

A field experiment was carried out during the Kharif season of 2025 at the Crop Research Farm, Department of Silviculture and Agroforestry, College of Agriculture, IGKV, Raipur, India. The study aimed to evaluate the “Effect of Organic and Inorganic Fertilizers on the Growth and Yield of Sesame (Sesamum indicum) under Indian Rosewood (Dalbergia sissoo) Based Agroforestry in the Chhattisgarh Plain.” using the variety Vibhuti 999 Super. The experiment was laid out in a randomized block design with nine treatments (T1-T9). Among the treatments, T5 (75% inorganic + 25% organic fertilizer) consistently recorded the highest values for growth parameters, including plant height, number of leaves, number of branches, and collar diameter, at all growth stages. Similarly, the highest yield attributes and productivity—such as number of capsules per plant, capsule length, seeds per capsule, seed test weight, seed yield (kg ha⁻¹), stover yield (kg ha⁻¹), harvest index (%), oil content (%), and oil yield (kg ha⁻¹)—were also observed under treatment T5 (75% inorganic + 25% organic fertilizer).
