Abstract: Field experiment was conducted at AICRP on Vegetable Crops of OUAT, Bhubaneswar, Odisha during summer, 2018 to study the efficacy of different sources of nutrients on growth and yield of cucumber. The experiment was laid out in RBD replicated thrice having twelve INM modules including absolute control.The results revealed significant variations among different treatments for growth and yield in cucumber. Invariably, integrated application of 50% of RDF + FYM @ 10 t ha-1 + vermicompost @ 2 t ha-1 + biofertilizer recorded not only significantly highest vine length (1313.00 cm), primary branches vine-1 (3.00), fruit length (19.79 cm), fruit girth (15.13 cm), average fruit weight (194.13 g) and fruit vine-1 (11.07) but also fruit yield (214.05 q ha-1) than rest of the treatments. Similarly, the module also showed significantly lowest sex ratio (3.43) and maximum extended period of fruit harvesting (41.00 to 68.00 days). On the other hand, significantly lowest vegetative growth (i.e., vine length of 550.67 cm and primary branches vine-1 of 1.93), delayed in 1st fruit harvest (44.33 days), lowest yield attributing parameters (i.e., fruit length : 12.76 cm, fruit girth : 10.57 cm, average fruit weight : 92.00 g, fruits vine-1 : 4.20) and total fruit yield (53.70 q ha-1) in plots without any fertilizer and biofertilizer. The next better treatment was integrated application of 100% RDF + FYM @ 10 t ha-1 + biofertilizer for growth and yield in cucumber.Thus, it may be concluded that integrated application of 50% RDF + FYM @ 10 tha-1 + Vermicompost @ 2 t ha-1 + biofertilizer not only increases vegetative growth but also fruit yield in cucumber.
