The experiment was carried out to “Effect of NAA (foliar spray) and colour poly wrappers on rooting, survival and economics of air-layering of guava (Psidium guajava L.) cv. Gwalior 27” during the season of Kharif 2016-17 at the Horticulture nursery, Department of Horticulture, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, (M.P.). Results revealed that significantly maximum rooting such as number of primary roots per layer (7.46) and secondary roots per layer (9.55), length of primary roots (8.07 cm) and secondary roots (9.04 cm), dry weight of roots per layer (0.209 g), rooting percentage (61.12%) and survival percentage (47.31%) in air layers of guava was recorded with the application of 125 ppm NAA (N4). Black poly wrapper (W2) exhibited significantly maximum number of primary roots per layer (6.57) and secondary roots per layer (9.21), length of primary roots (9.74 cm) and secondary roots (10.02 cm), dry weight of roots per layer (0.168 g), rooting percentage (54.79%) and survival percentage (43.75%) at 60 days after layering. Interaction was also significantly maximum under the treatment combination of N4W2 (NAA @ 125 ppm + Black poly wrapper) over the N1W1 (NAA @ 50 ppm + White poly wrapper). number of primary roots per layer (8.55) and secondary roots per layer (10.85), length of primary roots (10.49 cm) and secondary roots (10.77 cm), dry weight of roots per layer (0.247 g),rooting percentage (65.63%) and survival percentage (50.93%). The maximum net return of Rs 14559.00 and highest cost benefit ratio 1: 3.51 was recorded in treatment N4W2 (NAA @ 125 ppm + Black poly wrapper).
