|Abstract:||The present investigations were carried out during the year 1996-1997 at the Instructional-cum-Research Orchard of Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, with a view to find out the effect of methods of application as soil and soil + foliar application of nitrogen on growth, yield, fruit quality and leaf nutrient status of pomegranate cv. Mridula. The experiment was laid out in split plot design with 4 main treatments as levels of nitrogen and 2 sub-treatments as methods of application, replicated thrice. Four plants of uniform size were selected as experimental plants in each treatment. The growth of the plants as assessed by absolute growth rate of height and spread was significantly influenced by the nitrogen levels. The nitrogen level 700g per plant had registered the highest absolute growth rate than other treatments. The fruit number and weight of fruits per plant, average fruit weight, volume and diameter of fruit were found to be more from the treatment, 600g nitrogen per plant. However, the rind thickness remained unaffected. The fruit quality in respect of T.S.S, acidity, juice percentage and sugars deteriorated with the highest level of nitrogen. The leaf nutrient status of nitrogen significantly increased with the increased application of nitrogen. Application of nitrogen through soil + foliar was superior than soil application alone in respect of growth and yield characters. Average fruit weight, volume and diametere fruit, weight of 100 grains were higher in plants which had received nitrogen through both ways i.e. soil and foliar. The highest juice percentage, T.S.S and sugar percentage were recorded in soil + foliar application. The results obtained in the present investigation indicated that application of 600g nitrogen per plant through soil and foliar found to be optimum for better growth, for higher fruit production and for better quality fruits. The concentration of N, P, K, Ca and Mg were 2.21%, 0.37%, 1.427%, 1.609% and 0.810% respectively. Therefore, the said dose applied through soil + foliar may be recommended.|
