This study was carried out during the two successive seasons (2018 and 2019) on the first and second ratoon of healthy uniform banana cv. Williams (Musa spp.) Plants grown in sandy soil under drip irrigation system in a private orchard located at El-Tahadi region, Cairo Alexandria desert road, Behaira governorate, Egypt. The investigation aimed to study the effect of different slow release potassium fertilizer (SRKF) (50% K2O) rates (100%, 75% and 50%) were added as soil application during mid March, mid June and mid September while, potassium sulphate dose used in control treatment was added at monthly internals as soil application from mid March until mid October on vegetative growth, productivity, total yield income and net return/feddan of banana plants. The obtained results showed that, all treatments had a significant effect on enhancing the vegetative growth parameters, i. e. number of green leaves/plant, plant total assimilation area (m2/plant), leaf total chlorophyll content (SPAD) and leaf macro element content (N, P and K) (%) and leaf micro element content (Fe, Zn and Mn) (ppm) also, improving the productivity properties, i. e. yield (ton/feddan), bunch weight (kg), number of hands/bunch, hand weight (kg), number of fingers/hand, finger weight (g), finger length (cm), finger circumference (cm), finger pulp weight (g), finger pulp/peel (ratio), TSS (%), TSS/TA (ratio), total sugars (%), in addition, the total yield income (1000 LE) and net return/feddan (1000 LE) in both seasons, respectively. Moreover, all treatments had no significant effect on plant pseudostem height (cm), pseudostem circumferences (cm) and leaf area (m2) of plant in both seasons, respectively and bunch length (cm) in the first season. Treatment of (100% slow release potassium) gave the highest values of physical and chemical properties of banana plants cv. Williams in both seasons. Compared to, control treatment (100% potassium sulphate) and treatment of (50% slow release potassium) gave the lowest values under the same conditions of this study in both seasons, respectively.
