Abstract:
The present investigation was under taken to study “Effect of GA₃ and NAA on plant growth and yield of Cherry Tomato (Lycopersicon esculentum var. cerasiforme) under polyhouse condition”. Variety -Pusa Cherry tomato-1. The experiment was laid out in Randomized block design with 12 treatments and each replicated thrice. The treatments consist plant growth regulators GA₃ and NAA. Among these 12 treatments, the growth attributes like plant height, total number of leaves per plant, number of flowers /cluster are maximum, yield attributes like, average fruit weight, fruit yield are maximum and The maximum plant height (175.15) was recorded in the treatment T₆ (GA₃ 75 ppm) and minimum plant height (149.14) was observed in case of T₁ (control). The maximum fruit yield per plant (6.94 kg) was recorded in the treatment T₆ (GA₃75 ppm) and minimum fruit yield per plant (1.35 kg) was observed in case of T₁ (control).The maximum fruit diameter (5.52) was recorded in the treatment T₆ (GA₃75 ppm) and minimum fruit diameter (1.06) was observed in case of T₁ (control).
