| Abstract:
A field experiment was carried out in two successive autumn seasons (1996 and 1997) at El Bossily site on the west side of Roistta branch of the River Nile in Egypt to study the response of snap bean (Phaseolus vulgaris L.) var. Giza 3 to inoculation with bio-fertilizers i.e. non-symbiotic Azospirillum lipoferum and soil yeast (Candida sp.), in the presence of decreased doses of chemical fertilizers i.e 50% and 75% of NPK doses compared with 100% of NPK on vegetative growth parameters, pods quality and nodulation status. The results obtained showed that bio-fertilizers significantly enhanced nodules formation, especially in the presence of decreased doses of chemical fertilizers. Vegetative growth parameter i.e. plant height, leaves number, fresh and dry weight per plant were significantly increased by the combination of bio-fertilizers and/or different levels of NPK. Also, bio-fertilizers with various rates of NPK improved pods quality, such as increased crude protein percentage, increased total carbohydrate content and reduced the fiber percentage. It can be concluded that Giza 3 variety showed better vigorous growth plants with higher quality and yield of pods in response to bio-fertilizer applications with the two levels of NPK (50,75%) under sandy soil conditions. | |
