The present studies were conducted to ascertain the effect of different combinations of N, P and K fertilizers on the yield and quality of Perlette grapes. The yield and quality characteristics varied with the different combinations of N, P and K. The mean pooled data indicates that the maximum number of bunches/vine (2.28) were obtained in N1P1K1 combination. The mean bunch weight was however, significantly higher (497.2 g) in a fertilizer combination N1P2K2 followed by combination N1P1K2 (469.3). The higher yield /vine (10.3 kg) was obtained in N1P2K2 combination. The quality parameters viz., TSS, acidity and TSS/Acid ratio also varied with change in fertilizer dose. The significantly higher TSS (19.1%) was obtained in the bunches harvested from the vines given 75 g N, 50 g P and 150 g K. The TSS/Acid ratio was significantly higher (37.3). Thus the fertilizer combination N1P1K2 (75g N, 50 g P and 150 g K)/ year age of vines should be recommended in vine yards to obtain higher yield and better quality fruits.
