| Abstract | ||||
| This work was carried out during the two successive summer seasons of 2016 and 2017 in a Private Farm, Dondet Village, Meet Ghamr District, Dakhlia Governorate, Egypt to study the effect of various sources of nitrogen fertilization which equal 60 kg N/fad., on growth, yield and pod quality of snap bean cultivars (Paulista and Bronco) grown in clay soil under flood irrigation. The results showed that, fertilizing Paulista cultivar with 30 kg N as organic nitrogen (ON) + 30 kg N as MN/fad., (ammonium sulphate) + Nr (nitrobein) increased dry weight of leaves, branches and shoot dry weight/ plant, chlorophyll a, b, total (a+b) in leaves tissues, total yield/fad., and average number of pods/ plant as well as total carbohydrates and total protein in green pods in both seasons. Whereas, the interaction between fertilizing of Bronco cultivar with 20 kg N as ON+40 kg N as MN/fad.,+Nr increased average pod weight and total fibers in green pods in both seasons. | ||||
