Effect of Foliar Sprays of KNO3 on the Yield and Fruit Quality of Kinnow

Citrus is a huge important fruit crop for its unique flavorful taste and dietary value. High yield and better quality of citrus fruit is directly dependent on the best fertilizer ratios. The present study was aimed to check the effect of liquid KNO3 on growth and yield of citrus, alone and in combination with conventional fertilizers (N: P: K 800: 400: 400 g/plant). The experiment was done according to randomized complete block design (RCBD), with eight treatments and four replications. Data of growth parameters such as number of fruits per plant, Weight of Fruit (g), length of fruit (mm), width of fruit (mm), peel thickness (mm), peel weight (g), Juice weight (g), juice percentage (%), Rag weight (g), TSS and Yield per plant (Kg) to evaluate the effect of different KNO3 doses on plant growth and produce. Data showed that the maximum fruit weight in T3 (155 g) and comparatively higher results of fruit yield per plant were obtained in T5 (42 kg). It was concluded that liquid KNO3 along with the conventional fertilizers played an important role to enhance the fruit quality and yield in the climatic conditions of Sahiwal.
