Abstract
The experiment was conducted during June to September of 2022 and 2023 in plastic greenhouse. Plantlets of the released banana cultivar Grand Nain were produced in the Plant Tissue Culture Laboratory of Kassala and Gash Research Station, Sudan. The objective of this research was to evaluate the impacts of different frequencies of foliar fertilization on banana plantlet development and growth under greenhouse conditions. The experiment consisted of two factors, three types of foliar fertilizers were (Nobel Fort NPK, Alnoha fertilizer NPK and Growth Foliar NPK), arranged in the main plot and applied frequencies were arranged in the sub-main plot. The treatments were randomly laid out in a split-plot design with three replications. The results showed that the fertilizer frequencies every week recorded the highest values of plant height, plant girth, number of leaves per plant, leaf length, leaf width, root length, root girth and number of roots per plant compared to frequencies every 3 weeks. Spraying foliar fertilization every week improved growth parameters.
