Impact of Foliar Application of Plant Bioregulators on Morphological, Floral and Yield Traits in Bottle Gourd [Lagenaria Siceraria (Molina) Standl.] CV. Pusa Naveen

The present investigation entitled “Impact of foliar application of plant bioregulators on morphological, floral and yield traits in bottle gourd was conducted at the Horticultural Research Centre of SVPUA & T, Meerut, U.P. The experiment was laid out in Randomized Block Design with three replications. The field experiment consisted of five concentrations each of GA3 (5, 10, 20, 50 & 75 ppm), Ethrel (50, 75, 100, 150 & 200 ppm), NAA (50, 75, 100, 150 & 200 ppm) and control (Water Spray) were applied at 2 and 4 leaf stages on bottle gourd cv. Pusa Naveen during the years of 2013 and 2014. It was observed that GA3 75 ppm registered the maximum vine length (4.96 m) and Number of primary branches (22.01) in comparison to all other treatments. Whereas, Ethrel 200 ppm improve the female flowering time (44.46 days), narrower the sex ratio (1.30), increase the number of fruits per vine (9.95) and total yield (357.42 q/ha) followed by NAA 200 ppm and GA3 5 ppm.
