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...

Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen has been found to increase the content of alkaloids in some of the medicinal plants. Objective: The aim of this study was to compare the effects of nitrogen bio-fertilizers, conventional nitrogen fe...

Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...

in order to investigate effects of optimum use of manure and nitrogen fertilizer on yield and yield components of corn single cross 704 (late maturing, non-prolific and dent) in different levels of irrigation water. a field study was conducted in 2005 year in agriculture experiment station of college agriculture, arak university (34o 32′ n, 50o 31′ e; 1759 m above mean sea level). design of exp...

water is the most important factor for agriculture development in iran. accordingly the optimal consumptione of water is very important. using pressurized irrigation system is one of the methods to improve agricultural water management. the objecttives of this research were to compare two irrigation methods of furrow and trickle irrigation systems impacts on quantity and quality characters of s...

The aim of this work was to analyse the influence of soil water content and distribution on fruit quality in 5-year-old ‘Manzanilla de Sevilla’ olive trees in pots subjected to different irrigation treatments for 3 years (2007-2009). The experiment was carried out near Seville, in southwest Spain. Four water treatments were considered: 1) T0, trees were under dry farming conditions except for s...

A 2-year greenhouse study was conducted at Clemson University, Clemson, S.C., in 2003 and 2004 to determine drought responses of six bermudagrass (Cynodon spp.) cultivars at four irrigation intervals. Cultivars selected from the 2002 National Turfgrass Evaluation Program Bermudagrass Trial were ‘SWI-1012’, ‘Arizona Common’, ‘Tift No.3’, ‘Tifsport’, ‘Aussie Green’, and ‘Celebration’. Treatments ...

glasswort(salicornia europaea l.) as an important halophyte plant is capable to accumulate nacl in aboveground part (fully edible) in considerable quantity. to evaluate the effect of irrigation levels and nitrogen fertilizer on the yield of seed and oil, and also harvest index of glasswort, a split plot experiment was conducted based on randomized complete block design with three replications a...

Winter wheat is threatened by drought in the Huang-Huai-Hai Plain of China, thus, effective water-saving irrigation practices are urgently required to maintain its high winter wheat production. This study was conducted from 2012 to 2014 to determine how supplemental irrigation (SI) affected soil moisture, photosynthesis, and dry matter (DM) production of winter wheat by measuring the moisture i...
