Res. and Exp. Center of Fac. of Agric. Moshtohor, Benha University, Toukh Directorate, Qalyubia Governorate, Egypt, during two successive summer growing seasons of 2015 and 2016 to study the effect of three water stress, i.e. normal irrigation, skipping the second irrigation (skipping one irrigation during vegetative growth stage) and skipping the fifth irrigation (skipping one irrigation during kernels filling stage) and four nitrogen fertilizer rates, i.e. 0, 50, 100 and 150kg N/fed as well as three potassium fertilizer rates, i.e. 0, 24 and 48 kg K2O/fed on growth, yield and its components as well as some kernels chemical properties of maize (white single cross hybrid 2031 for Misr hytech Seed Int.,). Results of combined analysis of the two seasons showed that kernels filling stage was the most sensitive to water deficit stress and preventing irrigation at this stage (skipping the 5th irrigation) caused marked decrease in mean values of allmost maize yield and its components, while, full irrigation treatment appeared to be the best irrigation treatment sine it enhanced all maize traits under study. Planting maize under water stress by skipping the 2nd irrigation and skipping the 5th irrigation significantly decreased mean values of grain yield/fed (kg) by 25.49 and 41.04 % respectively, compared to mean values of grain yield/fed (kg) of maize under normal irrigation. Planting maize when received 150 kg N/fed caused significant increase in all mean values of maize traits under study such as plant height (cm), ear height (cm), No. of ears/fed, ear diameter (cm), ear length (cm), No. of rows/ear, No. of kernels/row, No. of kernels/ear, ear weight (g), kernels weight/ear (g), kernels shelling (%), 100-kernel weight (g), ear yield/fed (kg), grain yield/fed (kg), stover yield/fed (kg), biological yield/fed (kg), harvest index (%), kernels nitrogen content (%), kernels crude protein (%), nitrogen uptake/fed (kg) and protein yield/fed (kg) Meanwhile, the highest mean values of potassium use efficiency (KUE) which were recorded from growing maize when received 100 kg N/fed. Growing maize under the higher potassium rate (48 kg K2O/fed) was produced the maximum mean values of plant height (cm), No. of ears/fed, ear length (cm), No. of kernels/row, No. of kernels/ear, ear weight (g), kernels weight/ear (g), 100-kernel weight (g), kernels shelling (%), ear yield/fed (kg), grain yield/fed (kg), stover yield/fed (kg), biological yield/fed (kg), harvest index (%), kernels potassium content (%), nitrogen uptake/fed (kg) and protein yield/fed (kg) while, the highest mean values of KUE which were recorded from growing maize when received 24 kg K2O/fed.

A total of 34 sires and 230 dams from MN strain, 32 sires and 194 dams from MT strain were chosen randomly from 250 cockers and 600 pullets to produce purebreds and crossbreds progenies in the first generation.

In the second trap the highly abundance of weevil for the sampling date 11/4/2017 (38 insects). Also, the study showed that the number of females was higher than the males in most cases. The highest population was recorded during 9/10/2017 in the first trap (33individuals), but the date 11/4/2018 showed the highest R. ferrugineus abundance in the second trap (34insects).The current study indicated that there were highly significant differences between the total number of males and the regions, but there was no any effect of seasons separately on this population in the trap 1. Also, the interaction between the regions and study seasons had no any effect on the male's populations. There were no any effects for regions and study seasons on the population of R. ferrugineus inside the trap number 2. In trap 1, there were positive correlations between the effect of females and temperature on the population of the males. Also, the same correlations were observed for effect of males and temperatures on the population of female populations. However, the effect of relative humidity factor on the population of male and females was negative effect in both tested traps. The study indicated that El-Behira region harbored more R. ferrugineus than Alexandria during the two study seasons. The average insects were 4.615 and 3.653 insects in Alexandria and 6.5 and 5.57 in El-Behira, during the two seasons, respectively.}, keywords = {Rhynchophorus ferrugineus,Fluctuation,Red palm weevil}, url = {https://assjm.journals.ekb.eg/article_131636.html}, eprint = {https://assjm.journals.ekb.eg/article_131636_3465e55e47d1bdeaa4096757b4c663be.pdf} } @article { author = {S.

The biology and predatory potential of this coccinellid were studied on the 4th nymphal instar of two aphid species, Aphis craccivora Koch. and Schizaphis graminum (Rondani). By rearing on A. craccivora at 20, 25 and 30°C the incubation periods of C. undecimpunctata eggs were 5.84, 4.32 and 3.62 days, led subsequently, to 80.20%, 94.40% and 64.40% hatching, respectively, opposed to 5.98, 4.60 and 3.42 days with 74.40, 90.40 and 62.00% hatchability when rearing took place on S. graminum. The total larval duration lasted 9.96 days on A. craccivora, being, significantly, shorter than the 10.67 days resulted from rearing on S. graminum. Throughout the whole period of the larval stage feeding on the 4th instar nymphs of A. craccivora and S. graminum, a single larva fed on163.54 or 170.21 nymphs, respectively. C. undecimpunctata female's longevity elapsed 64.04 and 63.19 days, respectively. A single mated female deposited 686.69 eggs when reared on A. craccivora, opposed to 590.57 eggs by feeding on S. graminum. These results concluded that rearing of C. undecimpunctata on A. craccivora proved the best to obtain immature stages of shorter durations, much lower consumption and the highest reproductivety of eggs. }, keywords = {Coccinella undecimpunctata - Biology - Predatory potential,Aphis craccivora,Schizaphis graminum}, url = {https://assjm.journals.ekb.eg/article_131637.html}, eprint = {https://assjm.journals.ekb.eg/article_131637_7af6a03da335935c4e5113410ba0bca8.pdf} } @article { author = {S.

The soil fertility quality index, easier to compute with fewer parameters, can be used as a quick tool to evaluate soil quality and to measure changes occurring after using different management practices. This study suggests that using soil fertility quality index to evaluate agricultural soil fertility quality can provide similar results even when different indicator methods and models have been used in the study area. In this study, SFQI determined to be the most accurate method for evaluation of soil fertility quality, because it took all soil parameters into consideration and gave the most consistent results.
