| Abstract | ||||
| Field experiment was conducted under open field and net-covered greenhouse at El-Qanater Research Station Farm in Qalubiya Governorate to investigate the effect of different types of bio fertilizers, compost and NPK on growth and yield of common bean (Phaseolus vulgaris L.). The population fluctuation of aphid, and white fly, attacking common bean were studied. The obtained results indicated that the maximum air temperature was decreased, but minimum air temperature and the relative humidity % were increased under net-covered greenhouse compared with open field. The growth parameters were increased under net-covered greenhouse compare to open field. NPK content of leaves as well as yield and its components were increased compared with open field conditions. The statistical analysis of the obtained data revealed that there were significant differences in white fly and aphid stages among most of the tested treatments under field conditions and green house. The highest infestation by whitefly and aphids were recorded at NPK treatment, while the lowest were recorded at B.t ½NPK + Nitrobein, under field conditions. The highest reduction percentages of whitefly and aphid populations were recorded in the treatments of B.t, followed by the treatments of half recommended rate of NPK + Nitrobein and half recommended rate NPK + Phosphoren. On the other hand, the lowest reduction percentages were recorded in treatments of one recommended rate of NPK and compost under open field and green house conditions of the first and second seasons. | ||||
