Abstract: ABSTRACT The present investigation on the effect of nutrient sources on cutting production and rooting in chrysanthemum (Dendranthema grandiflora Tzvelev) was carried out at Experimental Farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2018-2019 under a naturally ventilated polyhouse with the objective to find out the effect of nutrient sources on cutting production and rooting in chrysanthemum cultivars. The experiment was laid out in Randomized Block Design (factorial) with five treatments on three commercial chrysanthemum cultivars replicated thrice. Vermicompost, full doses of P and K and half dose of N were incorporated into the beds one week before planting according to the treatment. The remaining half dose of nitrogen was applied after 30 days of planting. Azotobacter and PSB were applied by dipping the roots of the cutting into a slurry of 200g of the inocula dissolved in one litre of 10% sugar solution at the time of planting whereas VAM (2 g/plant) was applied directly into the planting pit. Besides the application of basal dose of N, P, and K, a single dose (100 ppm) of N and K was also applied through fertigation twice a week. Cow urine was sprayed once in a week @ 5% and jeevamrit (5%) was given at 15 days interval @ 250ml/plant as soil drenching.The results revealed that minimumtime for cutting production (25.67 and25.33 days in 2nd and 4th harvest), maximum number of cuttings/plant/harvest (26.83, 32.83, 36.50 and 52.50 in all four harvests, respectively), total number of cuttings/plant (142.67), yield of cuttings/m2 (670.83, 820.83, 912.50 and 1312.50 in all four harvests, respectively), minimum days for rooting (20.00 and 18.17 days in 3rd and 4th harvest, respectively), maximum number of roots (36.89 and 34.78 in 3rd and 4th harvests, respectively), maximum weight of rooted cuttings (2.04 g in 3rd harvest), maximum percentage of healthy rooted cuttings (98.55 % in 4th harvest) and intense green colour of leaves (YGG 147 A) were recorded with the application 22.5 g/m2 each of NPK + biofertilizers + vermicompost (1 kg/m2) + FYM @ 5 kg/m2 (as basal) along with N & K 100 ppm as fertigation twice a week (T2). The nutritional treatment T3 comprising of cow urine (5%) resulted in maximum fresh weight of cuttings (3.21 and 2.12 g in 2nd and 3rd harvest, respectively) and maximum root length (3.91 cm in 3rd harvest). The cutting yield and rooting response of commercial chrysanthemum cultivars was noted in T2.
