The main objective of this study was to analyse the shade effect on development, productivity and excellence of grape fruits (Kishmishi seedless). To attain this, three sun (AM sun, PM sun, Full sun) treatments was linked with those plants growing in three shade treatments (50% shade, 80% shade and 100% shade). Different physical, chemical, ecological and quality factors were evaluated under six diverse treatments. Results showed that 50% shade plant stimulated differences in physiological attributes such as enhanced photosynthesis and augmented leaf area index (LAI), resultant in improved performance than conceivable in direct sun light. Accordingly, grape plants grown under 50% shade produced greater quantity (number) of fruits for example 10,350 individual fruits/plant and greater fruit weights (49 and 12 g fresh and dry weight/fruit respectively) with better fruits quality, than those grown in direct sun light or in 80% and 100% shade. Moreover, 50% shade plants had greater biochemical (nutritional, minerals and vitamin contents) and physiological attribute improvement i.e. greater fruit weight and fruit length which would benefit grower to uphold great grapes yields in long term. Fruit quality assessment (FQA) was calculated and evaluation classes indicated that the 50% shade plant score highest grade point (5) and stood in very good class, followed by AM and PM sun with grade point 3.0 and categorized in moderate class. Other three treated plants (Full sun, 80 and 100% shade) score 2.0 and 1.0 grade points and classified into poor and very poor classes, respectively.
