Abstract

The experiment was carried out to improve the quality of banana cv. Grand Nain plantlets produced by tissue culture in greenhouse during January to April of 2022 and 2023. Five doses of NPK (20:20:20) viz: 0, 2, 4, 6 and 8 g/plant were applied. The treatments were replicated 3 times in randomized complete design (RCD) and each plot encompassed 4 plants. The results showed that the different rates of NPK affected growth parameters, roots length and number of roots per plant of banana plantlets. The highest values of plant height, plant girth, number of leaves per plant, roots length, root girth and number of roots per plant were obtained with 6 g/plant compared to control for the two seasons. Using of NPK fertilizer at rate of 6 g/plant was the most stable and economically feasible treatment.
