Effect of Spacing and Training Method on Growth and Yield of Off-season Ridge Gourd (Luffa acutangula L.) Cultivation Under Insect Proof Net-house Conditions. M.Sc. thesis, College of Agriculture, Agriculture University, Jodhpur.https://krishikosh.egranth.ac.in/handle/1/5810178743An experiment entitled “Effect of spacing and training method on growth and yield of off-season ridge gourd (Luffa acutangula L.) cultivation under insect proof net house conditions” was carried out during Rabi season of 2018-19 at College of Agriculture, Mandor-Jodhpur. The experiment comprised of nine treatment combination of viz. three levels of spacing 45 cm × 45 cm (S1), 45 cm × 60 cm (S2) and 45 cm × 75 cm (S3), with three training methods viz. Single stem (T1), Double stem (T2) and Triple stem (T3), laid out in factorial RBD with three replications. The results revealed that the plants grown in wider (S3) spacing recorded the maximum leaf area (94.72 cm2 ), the minimum internodal length (16.46 cm), earliest first flower appearance (23.74 days), earliest first anthesis (31.36 days), the maximum number of flowers produced per vine (134.88), production of first flower at a lower node (6.18), highest number of fruits produced per vine (62.44), maximum fruit weight (33.22 g), fruit volume (42.54 cc), TSS (2.34 °Brix) and yield per vine (2.07 kg). The maximum yield per plot (19.14 kg) was observed in close spacing (S1). Amongst the training methods single stem training (T1) recorded the maximum vine length (378.13 cm), number of leaves per stem (22.15), number of nodes per stem (22.89), leaf area (94.87 cm2 ), earliest first flower appearance (23.74 days) and first flower anthesis (31.98 days), the minimum internodal length (16.33 cm), production of first flower at lower node (5.96), the maximum fruits length (11.47 cm), fruit diameter (3.41 cm), fruit volume (47.18 cc) and fruit weight (33.81 g), while the highest number of flowers produced per vine (143.54), number of fruits produced per vine (66.88), yield per vine (1.79 kg) and yield per plot (17.86 kg) were recorded in triple stem training (T3). The treatment 45 × 75 cm spacing with triple stem training recorded the maximum numbers of flowers (145.35) and fruits (67.67) produced per vine while the treatment 45 × 45 cm spacing with triple stem training had the highest net returns (Rs. 86,142.0) as well as B:C ratio (2.78).EnglishThesis
