Effect of Sulfur and some essential oils applied as alone or in combination to control late and early blight diseases of potato plants during two seasons was studied. The findings of laboratory investigations results revealed that Sulfur at 3.0 g/L and Thyme as well as Citral at 6.0 ml/L resulted in a total reduction in the linear growth of A. solani and P. infestans. In field trials, the data indicated the all tested treatments altogether decreased the late and early incidence during two seasons. Highest decrease in the incidence of late and early blight diseases was obtained with the combined treatments between Thyme + Sulfur and Citral + Sulfur, which reduced the late blight ranged between 83.3 and 88.2 %. and early blight between 69.2 and 76.9 %, respectively. As for the potato yield during the two winter planting seasons, the results showed that obtaining the highest increase in potato yield was achieved with the combination between Thyme + Sulfur and Citral + Sulfur, which led to an increase in potato yield ranged between 66.7 and 74.3 %. This treatments also showed an increase in potato yield during the two summer planting seasons, which led to an increase in potato yield ranged between 53.8 and 60.3 %. All previous treatments increased the enzyme activities.The best treatments are combined treatments between Thyme + Sulfur and Citral + Sulfur which increase peroxidase, chitinase and β,1-3- glucanase more than 300, 240 and 203.6 % respectively.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121484527","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}

Cropping system cannot allow for recycling Silicon element by plants. The decrease of bioavailable-Si may have significant impacts on cereal crops. The assumption of the depletion of plant available-Si is still admissible, but new conspicuous have proven that phytoliths are a significant source of Silicon for plant. Plants uptake silicon in silicic acid form. Silicon concentrations vary greatly in plant aboveground parts, ranging from 0.1 to 10.0% SiO2 of dry weight basis or even higher. The difference in Si accumulation attributed to the ability of the roots to take up Si. It is obvious that most of the effects of Si were expressed through Si deposition on the leaves, stems, and hulls. In spite of Si has not been proven to be an essential element for higher plants, it is a beneficial element for the healthy growth and development and even productivity of many crop species, particularly for rice which contains about 10% SiO2 in shoots on a dry weight basis. The beneficial effects of Si are particularly distinct in plants exposed to biotic or abiotic stress. Silicon is effective in controlling various pests and diseases caused by both fungi and bacteria in different plant species. Silicon also exerts alleviative effects on various abiotic stresses including salt stress, metal toxicity, drought stress, radiation damage, nutrient imbalance, high temperature, freezing and so on. Also, Silicon has been widely reported to alleviate the plant water status and water balance, especially under various stress conditions in both monocot and dicot plants Numerous research studies showing that the application of Si enhances the tolerance of some plant species to toxic metals, including manganese Mn, zinc Zn aluminum Al, cadmium Cd and arsenic As. In addition, studies have shown that Si alleviates growth inhibition and oxidative damage.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"21 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131498462","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}

Yassen","doi":"10.36632/mejar/2020.9.3.44","DOIUrl":"https://doi.org/10.36632/mejar/2020.9.3.44","url":null,"abstract":"The importance of fertigation in increasing productivity with efficient and reduced consumption of water and nutrients with practically, no pollution is emphasized. In modern farming systems, fertigation is widely practiced as a cost effective and convenient method for applying soluble fertilizers to crops. Along with efficiency and adequacy, uniformity is an important fertigation performance evaluation criterion. Fertigation uniformity is defined here as a composite parameter consisting of irrigation and fertilizer application uniformity indicators. The use of fertigation, coupled with micro-irrigation, has continued to increase since it was first introduced in horticultural cropping systems. This combination provides a technical solution whereby nutrients and water can be supplied to the crop with high precision in terms of time and space, allowing high nutrient use efficiency. However, the correct estimation of crop nutrient and water needs is fundamental to obtaining precise plant nutrition and high nutrient use efficiency in fertigated cropping systems. Increasing food demand and decreasing water resources have composed a kind of pressure to find new technologies for efficient use of water and fertilizers in agriculture. Such technology can be able to save irrigation water from 30% up to 50%, as compared with surface irrigation, furthermore increasing crop yields and crop quality. Highest benefits of drip irrigation, some soil data such as, infiltration rate, soil texture and soil structure, crop characteristics and water resources properties ,water quality, surface as will as well water, must be considered in system design, management and operation. Fertigation is an agricultural technique and application together with water and fertilizer to soil and/or plants, stimulates yield and fertilizer use efficiency as well; therefore, and under this technique leaching of nutrients is completely prevented. In order to utilize fertigation successfully, the four main factors must be considered: (a) the consumption rate of water and nutrients throughout the growth season that result in optimal yields, (b) response in uptake of different crops to nutrient concentration in the soil, (c) monitoring for total soil water potential, nutrients concentration in soil and percentage of elements in plants as a function of time, (d) root mass and distribution due to irrigation regimes as well as soil types.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133354498","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}
