The present work was done in a private farm at El-Khatatba region during three successiveseasons of 2016/2017 (first ratoon), 2017/2018 (second ratoon) and 2018/2019 (third ratoon) of Ziv bananaplants (Musa cavendishii L.) grown on sandy soil to study NK nutrients requirements (fertigation) on vegetativegrowth, yield fruit quality, NK-efficiency and economic return. Nitrogen and Potassium were applied atdifferent rates and their combinations, Nitrogen (600g, 750 and 900 g actual N/plant/year) and potassium (750,1000 and 1250 g actual K2O/plant/year). They were used 240 unequal doses around the year and were add assolution by fertigation. Results revealed growth parameters of plant i.e. pseudostem height, circumference,number of green leaves and assimilation area at bunch shooting stage significantly increased by increasing therate of NK fertilizer. The rate of 900g actual N and 1250g actual K2 O gave the highest values for the abovecharacters compared with other treatments. Growth cycle of plants tended to decrease as fertilizers was increase.Increase the rate of fertilizers shortened the growth cycle duration of Ziv banana. The highest yield, bunchweight, finger weight and fruit characteristics were achieved from Ziv banana plants fertilized with 900g actualN with 1250g actual K2O/plant/year. NK utilization efficiency was affected with the rate of fertilizers. Thebetter value of NUE (42 &48 & 44.4Kg. fruit/g actual N) was obtained from plants fertilizer with 750 g actualN+1250 g actual K2 O while highest value of KUE was (40.8 & 48 & 45.6) with the rate900 g actual N+750 gactual K2 O under tested seasons. The economic return of Ziv banana plants gradually increase by increasing NKfertilizers. Plants were fertilized with the 900 g. N + 1250g. K2O/plant/year gave the highest income comparedwith other treatment. While the lowest rate of NK fertilizer (600 g N+ 750 g K2O plant/year) gave the cheapincome.
