Effect of Bone Meal and Intercropping on Productivity and Quality of Sesame (Sesamum indicum L.)

Abstract— A field experiment was conducted in Kharif season of 2024–2025 at the Agricultural Research Farm, Department of Agronomy, Himalayan University, Jollang, Itanagar, Arunachal Pradesh. The soil of experimental plot was sandy loam and loamy sandy in texture with pH ranges from 4 to 6. The experiment was laid out in a Randomized Block Design (RBD) with seven treatments each replicated thrice three. The treatments which are T1: Control, T2:Bone meal at 70 kg/ha.+ intercropping (2:1), T3: Bone meal at 70 kg/ha. +intercropping (2:2), T4: Bone meal at 70 kg/ha.+ Intercropping (2:1), T5: Bone meal at 70 kg/ha. + intercropping (2:2), T6: Bone meal at 70 kg/ha.+ intercropping (2:1), T7: Bone meal at 70 kg/ha.+ Intercropping (2:2). The results showed maximum productivity of were recorded significantly higher in the treatment T7 which is Bone meal at 70 kg/ha.+Intercropping (2:2), number of capsule/plant (.33.67), capsule length (3.5cm) , seeds/capsule (78), test weight (3.2g), economic yield (0.3 t/ha), biological yield (2 t/ha), but in harvest index T1: Control has shown maximum result i.e., (19.19) and maximum quality of oil content in sesame (6.35%) and in protein content (35.06%) were recorded in the treatment T7 as compared to all the other treatments.
