Response green bean plants growth, yield and nutritional status to foliar application of cytokinin under compost amendment

Abstract

The study was carried out during 2018 and 2019 seasons, on green bean (Phaseolusvulgaris L.) plants at private farm- El-Ayat, Giza governorate. The experiments were designed tostudy the effect of various rates of compost (0, 2, 4 and 6 ton fed-1) and different concentrations of cytokinin (0, 50, 100 and 150ppm) on growth, yield parameters and nutritional state of green bean plants. The results indicate that the addition of compost at a rate of 6 ton fed-1along with spraying of cytokinin at a concentration of 150 ppm led to the improvement of the growth and yield characteristics as well as obtaining the highest value of these characteristics compared to other experimental treatments.The same thing with the increase of compost additives and the concentration of cytokinin spray contributed greatly to improving the quality of the green bean crop, especially the content of protein, carbohydrates and fibers.With the same flow, the treatment of green beans with 6 ton fed-1 and spraying them with a higher rate of cytokinin(150 ppm) increased the nitrogen, phosphorous and potassium content of the leaves in both growing seasons.
