Effect of Pgrs on Vegetative Propagation of Lemon (Citrus Limon Burm.) Cv. Pant Lemon-1, Under Western U.p. Conditions

Abstract

Lemon (Citrus limon Burm.), the most important fruit crop of the citrus family, has chief importance in fresh consumption and processed food products. It has been grown very well in Uttar Pradesh, especially in western UP. In view, keeping the above point, the present investigation entitled “Effect of PGRs on Vegetative Propagation of Lemon (Citrus limon Burm.) cv. Pant lemon-1, under Western U.P. Conditions” was conducted during 2021-2022 at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). The experiment consisted of sixteen treatments and laid out in Randomized Block Design (RBD) with three replications. Each replication consisted of ten cuttings and total of 30 cuttings in each treatment. The whole experiment contained total of 480 cuttings. The treatment combinations were: T0 (Control), T1 (1000 ppm IBA), T2 (2000 ppm IBA), T3 (3000 ppm IBA), T4 (500 ppm NAA), T5 (750 ppm NAA), T6 (1000 ppm NAA), T7 (1000 ppm IBA + 500 ppm NAA), T8 (1000 ppm IBA + 750 ppm NAA), T9 (1000 ppm IBA + 1000 ppm NAA), T10 (2000 ppm IBA + 500 ppm NAA), T11 (2000 ppm IBA + 750 ppm NAA), T12 (2000 ppm IBA + 1000 ppm NAA), T13 (3000 ppm IBA + 500 ppm NAA), T14 (3000 ppm IBA + 750 ppm NAA) and T15 (3000 ppm IBA + 1000 ppm NAA). Overall, the treatment combination T12 (2000 ppm IBA + 1000 ppm NAA) gave significant results on days taken to bud sprout (8.53), sprouting (83.33%), plant height (15.55cm), number of shoots per cutting at 30, 60 and 90 DAP (2.98, 3.88 and 4.88 respectively), number of leaves per cutting (14.28), shoot diameter (3.41mm), number of roots per cutting (20.69), length of longest root (21.39cm), diameter of roots (0.77mm), fresh weight of roots (3.24g), dry weight of roots (0.71g), rooting (76.66%) and survival (83.33%) of lemon (Citrus limon Burm.) cv. Pant lemon-1 as compared to control under western UP conditions.
