The existing irrigation system namely drip and sprinkler adds cost to production. So, an alternate low-cost (rain hose irrigation) was compared with other systems. study proposed find out the optimum soil moisture by selecting a proper that supports management, enhanced productivity, high water use efficiency, also involves less on treatment comprises different methods of (drip, sprinkler, rain...

The development of a coupled crop model (Ador-Crop) and solid set sprinkler irrigation model (Ador-Sprinkler) is reported in this work. The crop model incorporates many of the features developed in the well-known CropWat model. Improvements include the use of thermal time and the input of daily ET0. The solid set sprinkler model applies ballistic theory to determine water distribution resulting...

Abstract Background Antioxidants or vitamins are organic compounds that needed in tiny quantities and have stimulatory role on growth productivity of different plants. Two field experiments were conducted two summer seasons to investigate the irrigation systems (spraying dripping) α-tocopherol foliar treatment with concentrations (0, 100 200 mg/L) some indices physiological aspects, yield its c...

Furrow irrigation systems have a greater application capacity, are less costly, and use less energy than sprinkler systems but furrow irrigation produces greater runoff, erosion, and deep percolation losses. Phosphorus (P) and nitrogen (N) losses are associated with runoff sediment, and can be minimized by eliminating irrigationinduced erosion. Excessive leaching of inorganic and organic solute...

Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis. Compared to the conventional system, higher and increasing yields of tomatoes were observed in ...

In croplands, the adoption of certain management practices may increase soil organic carbon (SOC) levels. this study, we evaluated short-term impact crop stover and interaction between irrigation method on SOC change in a continuous maize (Zea mays L.) system Spain. Four years after beginning experiment, total C fractions (particulate matter carbon, POM-C; mineral-associated Min-C) contents, st...

water user cooperatives were formed due to consideration to people's empowerment and participation in water investment and management. the purpose of this study was to investigate the mechanisms of development and strengthening of water user cooperatives in the aras river basin. the study population consisted of the management board members of the water user cooperatives in the aras basin in th...
