Res. Station, Agric. Res. Center, Beni–Suief Governorate, Egypt, to evaluate of some five garlic genotypes, namely Egyptian (Balady) and Sids-50 (soft neck garlic white), Sids-40, Eggaseed-1 and Eggeseed-2 (hard neck garlic purple) on some vegetative growth, bulb characteristics and productivity as well as Allicin content in cloves during fresh and cured yield . The results showed the uppermost plant height, maximum leaves number per plant and longest leaf, highest total plant fresh weight/ plant, bulb diameter, both fresh and cured yield / fed. were obtained by Sids-50 genotype in both seasons. Meanwhile, Eggaseed-2 cultivar gave the largest leaf width and bulbing ratio. However, Balday cultivar recorded the highest number of cloves/ bulb in both seasons. The relative increases in cured yield due to Sids -50 genotype were about (6.15 and 22.58 %) over Baldy cultivar , (30.18 and 31.03 %) over Sids-40, (15.0 and 24.59 %) over Eggaseed-1 and ( 68.29 and 80.95 % ) over Eggaseed-1 in the 1st and 2nd seasons, respectively. The maximum concentrations of Allicin content in fresh and cured cloves of garlic were recorded with the two cultivars Eggaseed-2 and Sids-40, while the minimum concentrations were recorded with Sids- 50 genotype and Baldy cultivar in both growing seasons. Conclusively: It could be concluded that the highest garlic growth, yield and its components can be achieved from Sids-50 garlic cultivar followed by cv. Balady, and Eggaseed-1 (purple).

The data revealed that addition of oat flour slightly increase in pH value but these values were decreased with the addition of fruits. Also the lower in protein contents cause lower in fat while the higher in fat, fiber and carbohydrate contents were higher than control. Mineral analyses of Si, Mn, and Fe contents were great difference between all treatments as they ranged between (28.7136.51) for Si, (4.61-5.26) for Mn, (3.51-4.11) for Fe and (3.31-3.61) ppm for Zn. Concerning the control, the values obtained were (14.71), (0.91), (0.71), (3.61) for Si, Mn, Fe and Zn respectively.

There for we conducted this study in five villages in Sharkia governorate, Egypt during 2017. The obtained results revealed that the remarkable differences in residue levels between sites depending on the agricultural intensity were found. We found different pesticides in all observation sites. We found many samples under any detectable contamination and the few positive samples only with low concentrations of pesticides. Thiamethoxam at El-Nakhas and Ezbet Issa and imidacloprid at Plant protection Institute, Belbeis and El-Mahmodia record a higher PHQ more than 1000 corresponds to consuming more than 1% of the median lethal dose (LD50) per day and therefore represent the toxicity of substances to honey. Conclusively, from these results it could be concluded that risks by ingestion of contaminated pollen and honey are of some concern for systemic insecticides, particularly imidacloprid and thiamethoxam, chlorpyrifos and the mixtures of cyhalothrin and ergosterol inhibiting fungicides. However, residues of neonicotinoid insecticides pose the highest risk by contact exposure of bees with contaminated pollen.","PeriodicalId":184675,"journal":{"name":"Journal of Productivity and Development","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129407945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
