Abstract:
The present experiment is “Effect of Plant Growth Regulators on Growth and Yield of Bottle Gourd (Lagenaria Siceraria var. Kashi ganga) Under Prayagraj Agro climatic conditions” was carried out during February, 2021to June, 2021 on Research field, Department of Horticulture, SHUATS, Prayagraj. The experiment was laid by randomized block design (RBD), with thirteen treatments T₀ control,T₁GA₃(20ppm) at 2 leaf stage,T₂GA₃(40 ppm) at 2 leaf stage.T₃GA₃ (20ppm) at 4leaf stage, T₄ GA₃ (20 ppm) at 4 leaf stage, T₅ NAA (80 ppm) at 2 leaf stage, T₆ NAA(100 ppm) at 2 leaf stage, T₇ NAA (80 ppm) at 4 leaf stage, T8 NAA (100 ppm) at 4leaf stage, T₉ Ethrel (100 ppm) at 2 leaf stage, T₁₀ Ethrel (150 ppm) at 2 leaf stage. T₁₁ Ethrel (100 ppm) at 4 leaf stage, T₁₂ Ethrel (150 ppm) at 4 leaf stage. The experiment was observation to be recorded Vine length (m), Number of branches per plant, Days to appearance of first male flower, Days to appearance of first female flower, Days to first picking, Fruit length (cm), Fruit weight (gm), Fruit diameter (cm), Number of fruit per plant, Fruit yield per plant(kg), Yield tones ha^-1. Among the respective treatment T₄was found superior over other treatments. The result of the experiment revealed that application of plant growth regulators (GA₃,NAA,Ethrel) had significant effect on vegetative as well as reproductive attributes. Treatment consisted of T4 GA₃ (20 ppm) at 4 leaf stage through recorded best performances with respect to almost all the characters viz., growth, flowering and yield followed by T8 NAA (100 ppm) at 4 leaf stage. It is concluded from the investigation that the treatment T4 GA₃ (20 ppm) At 4 leaf stage through was found suitable growth and yield for bottle gourd.
