Abstract: The present investigation was conducted with the objective to know the effect of different pruning intensity and nutrition on flowering and fruiting chareacters viz., time of panicle emergence, number of panicles, panicle length, number of flowers per panicle, panicles per branch, fruits set per panicle, sex ratio, fruit set and fruit drop. The experiments were conducted in Randomized Block Design with seven treatments i.e. T1=5 cm pruning+FYM@ 20 kg per plant, T2=5 cm pruning+ Vermicompost @ 10kg per plant, T3=5 cm pruning+ ZnSO4 @ 1.0% + Borax @ 0.4%, T4=10 cm pruning+ FYM@ 20kg+ Zinc Sulphate@ 1.0% per plant, T5=10 cm pruning+ Vermicompost @10kg+ Borax @0.4% per plant, T6=10 cm pruning+PSB 250g+ MgSO4 @0.5% per plant, T7=15 cm pruning+FYM @20kg+ Zinc Sulphate @1.0% per plant, T8=15 cm pruning+ Vermicompost @10kg+ Borax@0.4% per plant, T9=15 cm pruning+ PSB 250g+ MgSO4 @0.5% per plant, T10= Control (no pruning+ water spray). The present investigation revealed that all flowering and fruiting characters influenced significantly due various pruning intensity, organic and inorganic nutrient treatments during both the years except fruit set and fruit drop per cent. The highest panicles emerges, number of flowers per panicle, panicle length, number of panicles per branch and fruits set per panicle were recorded with the treatment T8.
