A study was conducted at Post Harvest Research Centre, Ayub Agricultural Research Institute, Faisalabad, Pakistan during the year 2009. The objective was to evaluate the effect of pre-harvest orchard management practices like nutrient application, pruning, spraying and number of irrigations on Kinnow fruit quality and yield. For this purpose, various lots of good looking, healthy, clean and fresh fruits were taken from major citrus growing area in Sargodha district i.e. Sillanwali, Sargodha and Bhalwal tehsils. The farmers were selected for this survey according to their orchard holdings upto 4.05 hectares. The results indicated that fruit diameter, fruit weight and peel thickness ranged from 64.33 to 71.58mm, 112.82 to 170.80g and 3.31 to 4.58mm, respectively in three tehsils of Sargodha district. The other physicochemical quality parameters like TSS, acidity and pH obtained from three tehsils of Sargodha district ranged from 10.57 to 12.66 Brix, 1.01 to 1.21 percent and 3.85 to 4.30, respectively. These parameters showed that Kinnow from Sillanwali and Sargodha tehsils was superior to that of Bhalwal owing to better pre-harvest management practices of their orchards. Improved fertilization (organic and inorganic), irrigation and pruning are main pre-harvest management practices that need special attention of the farmers to improve quality of Kinnow mandarin. In a nutshell, pre-harvest management of orchards is directly linked with quality and yield of Kinnow fruit.
