It is grown in all tropical regions and plays a key role in the economics of many developing countries. Banana and plantains are grown in about 120 countries. Globally, India leads the world in banana production and accounts to about 33.40% among all other fruit crops. Banana being a gross feeder requires high amount of nutrients for proper growth and production. However, it draws the nutrients from a very limited soil depth because of its shallow root system. The choice and dosage of International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 03 (2018) Journal homepage: http://www.ijcmas.com A field experiment was carried out during 2015-16, in the farmer’s field at Tulsigeri, Bagalkot district with a view to study the influence of post shooting sprays of nitrogen and potassium on quality attributes of banana Cv. Grand Naine. The investigation comprised of eleven treatments, each replicated thrice in RCBD and the treatments consists of post shooting sprays of Urea (1.00%, 1.50% and 2.00%), SOP (1.00%, 1.50% and 2.00%), combination of urea and SOP, sprays as per the package of practice were sprayed thrice after emergence of flag leaf. There was a significant impact of potassium and nitrogen on all characters chosen for this study. The results of experiment revealed that marked improvement in fruit quality of banana cv. Grand Naine under post shooting spray of SOP (2.00%) and urea (1.00%) in three equal splits (T11) as reflected by the maximum values recorded in pulp weight (115.67 g), peel weight (41.30 g), TSS (23.97 0 B) and total sugar (18.35 %). Whereas, highest ascorbic acid (7 mg/100 g) was reported in 2 per cent SOP (T8). Thus, the study clearly indicates that combined post-shoot spray of SOP (2.00%) with 1.00% urea improves the quality of banana cv. Grand Naine.
