Soil salinity is a serious problem facing many countries globally, especially those with semi-arid and arid climates. can have negative influences on soil microbial activity as well chemical physical processes, all of which are crucial for health, fertility, productivity. negatively affect physiological, biochemical, genetic attributes cultivated plants well. Plants wide variety responses to stress classified sensitive (e.g., carrot strawberry), moderately (grapevine), tolerant (wheat)...

The dramatic growth of the world’s population is increasing pressure on natural resources, particularly soil systems. At same time, inappropriate agricultural practices are causing widespread degradation. Improved management resources and identification potential capability soils therefore needed to prevent further land degradation, in dryland areas such as Egypt. Here, we present a case study El-Fayoum depression (Northern Egypt) model map suitability for 12 typical Mediterranean crops. Two...

In this paper, we propose a service-oriented reliability model that dynamically calculates the of composite web services with rollback recovery based on real-time reliabilities atomic composition. Our is hybrid both path-based and state-based models. Many models assume failure or error arrival times are exponentially distributed. This inappropriate for as dependent operating state including workload servers where service resides. manuscript, modify our previous (for software Doubly...

In the era of climate change, soil and different compartments agroecosystem suffer from forms water degradation, which an urgent need for management is required. Under arid semi-arid countries, degradation are more severe causing a decline in agricultural productivity, food security. Increasing led to decrease quality, global insecurity, ecosystem health problem, then non-sustainable development. Several human activities have worsened especially under require proper methods management. With...

For this reason optimization available has become a necessity not only point limited resources, but also relative to growing demand for food. Field experiments were conducted at Experimental Farm National Research Center, El-Nubaria, El-Buhaira Governorate, Western Delta, study effect automatic control localized irrigation system(LIS) as modified system on emitter's clogging and maize parameters in new reclaimed...

Abstract This research work was carried out to evaluate drought stress for the differentiation of bread wheat ( Triticum aestivum L.) genotypes in their ability tolerate drought. An experiment on six (‘Sides 1’, ‘Shindwell ‘Gemmiza 9’, ‘Sakha 93’, ‘Saheel 1’ and ‘Masr 2’). A randomized complete block design with three replications along two separate tests under drip sprinkler irrigation systems used this experiment. One treatments applied normal amount water other end-season conditions...

Natural resources are considered the main sources for our life, which include mainly of water, energy and food. Along with explosion global population, these previous under a serious threat that enforce all nations to double productivity fresh clean energy, healthy food by more than 50-70%. These increases not so easy achieve particularly climate change. Several approaches proposed mitigate change Water-Energy-Food (WEF) nexus especially applying nanomaterials (NMs). This review describes...

The aim of current research work is studying the effect two bubbler irrigation discharges (BD) were: a) 8 LPH and b) 12 LPH, different water quantity treatments from evapotranspiration (ET): 100%, 75%, 50% on uniformity coefficient (UC%), emission (EU%) variation (CV%), maize (Zea mays-L., HF-10 Varity) grain Hay yield. experiment design split in randomized complete block with three replicates. So, field for one growing season (2014) was conducted sandy soil at Agricultural Research...

Abstract Manual harvesting of sugarcane requires skilled labourers, as improper leads to a significant loss yield. Therefore, it is necessary move towards designing system capable on smallholdings, with high efficiency. This study aims determine some physico-mechanical properties stalks related harvester by making comprehensive analysis the compressing, bending, and shearing stalks. These were measured at three moisture content levels positions (base, middle, top) stalk varieties (G.T.54-9,...

In the light of crop shortage production, water scarcity and environmental pollution. The utilization biofertilizers as an algae extract modern irrigation systems has become paramount important to reduce chemical fertilizers ensure good distribution for plants. Therefore, two field experiments were conducted in Nubaria district at Agricultural Station National Research Centre, El-Behira Governorate within winter seasons 2015/2016 & 2016/2017 demonstrate influence systems, i.e., drip...
