| Abstract | ||
| This study was carried out during summer and nili Plantations in 2014 in Plant Protection Research Institute Station, Qualiobeya Governorate to sheet the light on the effect of different types and rates of fertilizer treatments on the rates of infestation of cucumber plants, cucumis sativus L. by different pests, Tetranychus urticae kach, T. cucurbitacearum (sayed) (eggs and mobile stages), Bemisia tabaci (Gennadius) (eggs, nymphs and pupa), Thrips tabaci (Lindquist) (nymphs and adults) and on the resultant fruit crop yields. Data revealed treatments, mycorrhiza and NPK recorded the highest infestation rate by T. urticae, T. cucurbitacearum and T. tabaci in summer and nili plantations. while (N2+k2o) fertilizer treatment curried out the lowest infestation rates by T. urticae, T. cucurbitacearum and B.tabaci. On the contrary N2 fertilizer recorded the highest infestation with whitefly. Orange mealy bugs, pseudococcus obscures Essing were firstly recorded on cucumber plants throughout nili plantation only by having the highest infestation on the plants treated with N2 fertilizer being significant differences with the other treatments except for mycorrhizal treatment. Both treatments, NPK and microelements recorded insignificant the highest weight in fruit crop yields. While mycorrhizal treatment demonstrated the lowest weight of crop yield. | ||
