Abstract
The investigation entitled “Effect of fertigation on growth, yield and fertilizer use efficiency in hybrid ridge gourd [Luffa acutangula (L.) Roxb.]” under open field condition was carried out at Vegetable Research Block of Division of Vegetable Crops, ICAR– Indian Institute of Horticultural Research, Hessarghatta, Bengaluru, Karnataka during 2018 -2019. The experiment was laid out with RCBD design with eight treatments and replicated thrice. The treatment T3 (Fertigation with water soluble fertilizers @ 150:90:150 kg NPK ha-1) recorded maximum vine length (635.31cm), internodal length (14.52 cm), number of leaves per vine (239.60), leaf area per vine (6263.78 cm2), number of male and female flower per vine (304.93 and 29.73) at 90 days after transplanting. The number of fruits per vine (19.68), average fruit weight (454.03 g), fruit yield per vine (4.03 kg), fruit yield per hectare (53.73 t), fruit girth (18.40 cm), fruit length (49.76 cm) and highest net returns (Rs. 555435.00 per hectare) and benefit cost ratio (2.22) was also highest in the same treatment. From this investigation we could conclude that, water soluble fertilizers at @ 150:90:150 kg NPK ha-1 is ideal for the maximum growth, yield and quality of hybrid Arka Vikram of Ridge gourd.
