Effect of plant growth regulators and thiourea on growth and yield of bottle gourd [Legenaria siceraria (mol.) standl] cv. Pusa Naveen

Abstract

The effect of plant growth regulators and thiourea on growth and yield of bottle gourd an experiment was conducted during kharif Season 2016 at the instructional farm mjrp college of agriculture and research Jaipur (raj.).The experiment consisting 13 treatment (NAA 150,200 and 250 ppm. CCC 100,200 and 300 ppm. Thiourea 200, 500 and 700 ppm and control were replicated three time in a randomized block design keeping plot size of 6mx3m. The seed sowing was done on 11 july 2016 in the furrow spaced at 2.5m apart maintaining a plant to plant distance of 0.75m. The application of plant growth regulators and thiourea singnificant effect the vegetative as well as reproductive attribute of the crop.The exogenous application of NAA 250 ppm (T3) recorded maximum vine length (6.70 m), nodes per vine (23.15) and leaf area (264.50 cm2).The CCC 300 ppm (T9) treatment produced maximum primary (20.95) and secondary branches (9.36) per vine but minimum vine length (4.33),nodes per vine (18.05) and leaf area (218.36 cm2) were observed in this treatment The maximum net return (Rs.204440 per hectare) and b:c ratio (2.76) were recorded under ethrel 400 ppm.
