Abstract : An experiment of integrated nutrient management was conducted on mango cv Himsagar during 2009--2010. The experiments were laid out in randomized block design with five replications and age of the tree is 7 years old with a spacing of 10×10 m. To observed the effect of integrated nutrient management on the yield and quality parameters were subjected to 1000:500:500 g NPK/tree (control) (T1); T1+Zn (0.5%)+B (0.2%)+Mn (1%)+Ca (0.6%) as foliar application twice (August and October) (T2); T2+Organic mulching (10 cm thick of dry leaves) (T3); (iv) T2+Organic mulching (10 cm thick of dry leaves) (T4); 1/2 T1+50 kg FYM+250 g Trichoderma (T5); 1/2 T1+50 kg FYM+250 g Azospirillium (T6); 1/2 T1+Azotobacter (250 g)+250 g Azospirillium (T7); and 1/2 T1+Azotobacter (250 g)+50 kg FYM (T8). Observation on the pooled data of yield and quality revealed that total number of fruits per tree was maximum in T6 and average fruit weight was also maximum in T6 (239.40). Similarly, for quality parameters fruit length and breadth maximum in T2 (6.78) and T3 (5.56) respectively. Peel percentage was highest in T1 (15.24%), stone percentage in T4 (17.66%) but the pulp percentage was highest by T5 (73.45%). Other quality parameters TSS, acidity, reducing sugar and total sugar was highest in T6 (19.16°Brix), T5 (0.21), T7 (4.48) and T6 (15.54) respectively. However, the overall performance of T6 treatment was better in yield and quality parameters which can be recommended for mango plantation in new-alluvial zone of West Bengal in the future.
