A factorial combination of four treatments (control (CW), optimal growing season water availability (IW), optimum nutrient availability (FW), and combined optimum water and nutrient availability (FIW)) in four replications were initiated in an 8-yearold Pinus taeda stand growing on a droughty, nutrient-poor, sandy site in Scotland County, NC and maintained for 9 years. Results for the first 4 y...

This study was conducted to evaluate the effect of titanium dioxide and titanium oxide foliar application during two growing stage on growth and forage production of maize during 2012 growing season in the research farm of Islamic Azad University of Varamin-Pishva Branch. The experimental design was randomized complete blocks arranged in factorial with four replications. The factors were includ...

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -...

Winter wheat (Triticum aestivum L.) grows in dry season but summer maize (Zea mays L.) coincides with rainfall in the North China Plain (NCP). Increasing rainfall use efficiency and harmonizing its utilization between the two species is an effective way to mitigate impact on groundwater deriving from wheat irrigation. One to four times water supply (W1, to W4) were employed in wheat, three wate...

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...

in order to study grain yield, yield components and growth indices in wheat, the experiment was carried out with five wheat cultivars at rbcd arrangement with 4 replications at gorgan university of agricultural sciences and natural resources. the cultivars included zagros, tajan, kohdasht, durum and n81-18 line. to measure studied traits (leaf, stem and shoot dried weight and leaf area) fifteen...

Stem segments prepared from pondweed (Potamo geton distinctus A. Benn.) turions (overwintering buds) elongate in anaerobic conditions, whereas there is almost no elongation in air. The anaerobic elongation was accompanied by a decrease in dry weights of stem segments, mainly due to consumption of storage starch in the amyloplasts of stem cells. On the other hand, total contents of amino acids i...

in order to study effect of irrigation with wastewater and foliar application of complete fertilizer on forage yield and seed yield and yield components of foxtail millet (setaria italica). a split plot experiment based on randomized complete block design with three replications was conducted at the agriculture institute of zabol university in year 2009. treatments included three levels of irri...
