Effect of Drip Irrigation and Bioregulators on Water use Efficiency and Fruit Yield of Kachri (Cucumis pubescens)

A field experiment was conducted during summer season of 2019 and 2020 at Niche Area Excellence Farm , Bikanerfor consecutive two years to study the effect of drip irrigation and bio-regulators on water use efficiency and fruit yield of kachri (Cucumis pubescens). The treatments consists of three drip irrigation schedules viz .40% 60% and 80% ETc and four levels of bioregulators viz. control (water spray), thiourea (500 ppm), N-acetyl cysteine (20ppm) and TGA (100ppm) foliar spray twice at vegetative and flowering stage. The experiment was conducted in randomized block design and replicated thrice. The study indicated that there was increase in fruit yield with increase in irrigation levels from 40% to 80% ETc. The study further revealed that number of fruit per plant increases continuously from 40% to 80% ETc. The study indicated that fruit yield was maximum in N-acetyl cysteine (20ppm) spray as compare to thiourea (500 ppm) and TGA (100 ppm) spray. The study also indicated that number of fruits per plant, fruit weight and water use efficiency (WUE) were higher in bioregulators spray as compared to water spray (control).
