Influence of soil and leaf nutrients on quality of kinnow mandarin grown in aridisol of Punjab, India
Keywords:
Aridisol, Kinnow orchards, Micronutrients, PunjabAbstract
The present study was conducted to determine the relationship between soil and foliar nutrient status with fruit quality of Kinnow orchards in aridisol of Punjab. All Kinnow orchards soils were found alkaline to saline in nature with pH value ranging from 8.4 to 9.5 and deficient of macronutrients while sufficient in most of micronutrients. Foliar analysis suggested that percent samples of different locations were nearly sufficient in Mn, Cu, Fe and Zn and deficient of K and N. Soil properties viz; pH, EC and CaCO showed an adverse relationship with 3 available major and micro-nutrients. Correlation studies suggested that soil properties showed a significant and negative relationships with soil and foliar N, Pand K, while non-significant but negative with Mn, Cu, Fe and Zn. The results show pronounced effect of the soil and leaf nutrient conditions on physico-chemical quality characteristics of 'Kinnow' mandarin fruit besides other un-foreseen factors at different locations.
