Abstract

An experiment on Ridge gourd (Luffa acutangula L.) Effect of Biofertilizer on growth and yield attributes of Ridge gourd (Luffa acutangula L.) under zone-7 of Karnataka. The experiment was carried out at Diploma (Agri) College Agricultural and Horticultural Research Station, Kathalagere, Davangere. In kharif season during the year 2022 with three replicated randomized block designs. With seven treatments in 6.5 x 5.5 m plot size twelve plant populations was maintained in each plot with normal spacing given 1.5 x 1.5 m row and plant to plant respectively. The results of the experiment revealed Treatment T5 (75% NPK + FYM +VC 1250 Kg/ha+ biofertilizer (Pseudomonous flourscence @ 2.50 kg/ha and Trichoderma viridae @ 750 g/ha) was shows better results recorded more number of primary branches/shoots (5.45 no) vine length (482.75 cm) Leaves /plant (66.83 Nos) earliest opening of first female flower shows in in DAS (40.58) highest fruit length/diameter also (45.08 /8.26 cm and fruit Yield recorded in (1.45 kg), 15.06 kg) & (4635.89 kg) plant,/plot and hector respectively.
