Effect of spacing and plant growth regulators on yield and economic of Zaid sesame (Sesamum indicum L.)

Abstract

The field experiment was conducted during Zaid season, 2020 at Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (UP) On sandy loam soil to investigate the Effect of Spacing and Plant Growth Regulators on Yield and Economic of Zaid Sesame (Sesamum indicum L.). The experiment was laid out in Randomized Block Design with nine treatments replicated thrice with the different spacing (30cm x 10cm and 45cm x 10cm) and different levels of NAA (10 ppm & 20 ppm), GA3 (10 ppm & 20 ppm), IAA (10 ppm & 20 ppm) and salicylic acid (10 ppm & 20 ppm) as foliar spray. Study revealed that Spacing 45cm x 10cm + GA3 10 ppm foliar spray at 30 and 45 DAS was recorded significantly higher Seed yield (8.27 q/ha), Stover yield (27.84 q/ha) as compared to all the treatment combinations. The economic analysis clearly indicates that higher B:C ratio (2.10) recorded with treatment of spacing 45cm x 10cm + GA3 10 ppm foliar spray at 30 and 45 DAS as compared to all treatment combinations.
