The aim of the study was to evaluate effect irrigation depths, via subsurface drip, on technological quality, productivity, and water use efficiency (WUE) sugarcane cultivars. experimental design balanced blocks with 12 two factors: cultivars (CTC 4, IACSP93-3046, RB86-7515, IACSP95-5000 IAC91-1099) depths (dry, deficit supplementary). From estimated evapotranspiration (ETc), equivalent 100% cr...

During the construction of high standard farmland, by introducing new software rainwater harvesting cellar technology, combining big data and intelligence, laying drip irrigation belts other field facilities in field, efficient water-saving was realized according to local conditions, problem supplementary key growth periods agricultural production solved.

The design and operation of supplementary irrigation schemes are dependent upon an accurate estimation of the "total available moisture" in the soil. This has been defined as the amount of water held between the limits of field capacity and wilting point in the effective rooting depth of the crop. Under irrigated conditions the effective rooting depth is that depth of soil from which the crop c...

in the water-limited areas, the great challenge of the agricultural sector is more production from less water that it can be achieved by increasing water productivity. a field study was conducted to compare various cultivars of wheat to water using line source sprinkler irrigation at gorgan research station in 2005-2006. the effect of variable water supply on yield and wue of six wheat cultivar...

Previous studies reported higher antioxidant and mineral micronutrient concentrations in organic compared to conventional wheat flour, but the reasons are poorly understood. Here we report results from a long-term, factorial field experiment designed assess effects of variety choice, supplementary irrigation contrasting fertilization regimes used production on nutritional quality yield spelt gr...
