Impact of improved practices on Kinnow fruit quality parameters produced at different ecological zones in climate change scenario

Abstract
Improved-practices like canopy management and plant-protection measures were applied on Kinnow fruit growing in three different districts of Punjab namely Sargodha, Toba Tek Singh (TTS) and Vehari, all of which were varying environmental conditions. Three orchards of uniform age, vigor and planting geometry were selected. Factorial RCBD was used in data analysis. Total 36 branches were tagged on each plant at different canopy positions, for data collection. Pathological fruit drop and pest-disease-damaged fruits were counted to be less produced on plants with application of improved-practices in all the three districts. Pruning was also used in canopy management, which improved plant’s micro-climate in order to reduce the wind-scare and stem-injury damage other than the problem about reduced fruit load being solved as well. As a result, fruit physico-chemical properties, polyphenols, antioxidant and sensory values were improved in all three locations, as compared to prevailing traditional farmers’ practices. Fruit yield quality parameters like A and B grades remained higher in all three districts for improved-practices plants than farmers ones. Among districts, Sargodha Kinnow fruit possessed more quality attributes than TTS and Vehari, which were further increased in plants with improved-practices. Climate change has brought more variability in TTS and Vehari districts, which has more adversely affected their fruit quality.
