Abstract: Response of Graded Level of NPK on morphological growth, flowering and yield quality of Shahi cultivars of litchi (Litchi chinensis Sonn). The NPK was applied through ring basin (RB) applied in two different split doses. Application of NPK significantly affected canopy volume, trunk girth, spread, canopy height, panicle length, yield and number of fruits per tree. Among different graded levels of NPK the applied 100g nitrogen and 100g potassium (T18) per year age of tree with 2/3 dose in April and 1/3 dose in June showed maximum canopy height (4.2m), maximum tree spread (7.75 m) and maximum canopy volume (32.14 m3) while minimum height (3.5m) was observed with the application of 75g nitrogen and 100 g potassium (T6) per year age of tree with 1/2 dose in April and 1/2 dose in June and minimum canopy volume,T13 (90.13 m3) was recorded with the application of 75 g nitrogen and 50 g potassium. Maximum trunk girth (84 cm) was recorded with the application of 100 g nitrogen per year age of tree and 50 g potassium per year age of tree (T7).The maximum panicle length (38.72 cm) was recorded with the application of 50 g nitrogen and 50 g potassium (T1) per year age of tree with 1/2 dose in April and 1/2 dose in June. The treatment consisting of 75:50:100 (T15) i.e.75 g nitrogen and 100 g potassium per year age of tree recorded the maximum yield of 128.00 kg per tree, while minimum fruit yield (51.25 kg per tree) was recorded with 50 g nitrogen and 100 g potassium in (T12). All the treatment showed 50% flowering stage and fruit set between 9th - 16th March and 21st–27th March respectively. Days taken from panicle emergence to fruit set was 50-55 days.
