The field experiment was carried on “Effect of plant growth regulators and micronutrients on growth and yield of ridge gourd (Luffa acutangula.L.)”cv.PKM-1 was carried out at the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar, Tamil Nadu during 2017-2018. Application of Ethrel. Triacontanol, 24 epi brassino steroid as foliar spray in 10 treatment combination in RBD with three replications. The biometric observations on growth attributes viz., plant height, number of branches plant-1, number of leaves plant-1, number of flowers plant-1, number male flowers vine-1, number female flowers vine-1 number of fruits plant-1, fruit set percentage, yield attributes viz., fruit weight, yield per hectare. All the treatments significantly influenced the biometric characters of ridge gourd and the results revealed that the treatment combination of 24 epi brassino steroid 2 ppm + ethrel 250 ppm + micronutrient 2% as foliar spray was found to be the best with ridge gourd fruit yield of 20.94 t ha-1 . From the experiment, it was concluded that the plant growth regulators and micronutrients viz., 24 epi brassino steroid 2 ppm + ethrel 250 ppm + micronutrient 2% were identified as the best to increase yield for ridge gourd.
