dc.description.abstractThe present investigations entitled “Studies on NPK fertigation on growth, yield and quality of pomegranate (Punica granatum L.) cv. Kandhari Kabuli” were conducted during 2011 and 2012 in the Pomegranate Block of Department of Fruit Science, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). The study consisted of three experiments, with variable rates of individual nutrients (N, P and K) and keeping other two constant at recommended dose. In experiment I (effect of variable N and recommended dose of P and K) treatment, T4 (75 % RD of N and RD of P and K) gave significantly higher tree growth characteristics,fruiting characteristics, physico- chemical fruit characteristics , leaf macronutrient and micronutrient over other treatments. Fertilizer use efficiency (FUE) of this treatment was also recorded better as compared to the conventional method of fertilizer application. For experiment-II (effect of variable P and recommended dose of N and K) highest tree growth parameters, highest fruiting characteristics, physico-chemical fruit characteristics, leaf macro and micro nutrient status and FUE was recorded for the treatment, T3 (50% RD of P and RD of N and K). For experiment III (effect of variable K and recommended dose of N and P) highest tree growth characteristics, fruiting characteristics, physicochemical fruit characteristics , leaf macro nutrient and micro nutrient was recorded for the treatment, T5 (100 % RD of NPK). Fertilizer use efficiency (FUE) of this treatment was also recorded better as compared to the conventional method of fertilizer application. With respect to the horizontal movement of available N, P and K in soil it was observed that under fertigation all the individual element concentrated mostly in surface soil layer i.e 0-15 cm layer followed by 15-30 cm layer and minimum under 30-45 cm soil layer. Under conventional method only N was observed to be concentrated in 15-30 cm followed by surface layer and minimum in 30-45 cm soil layer. The lateral movement of available N, P and K showed similar trend w.r.t. individual element and mostly concentrated about 10 cm away from emitter, followed by 20 and 30 cm in decreasing order irrespective of fertilizer application method.en_US
