in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...

The analysis of soil water partitioning in seasonally dry climates necessarily requires careful consideration of the periodic climatic forcing at the intra-annual timescale in addition to daily scale variabilities. Here, we introduce three new extensions to a stochastic soil moisture model which yields seasonal evolution of soil moisture and relevant hydrological fluxes. These approximations al...

the high yield depends on high dry matter production per unit area. azotobacter bio-fertilizer experiment to investigate the effect on the index, total dry matter accumulation and pishtaz and chamran wheat cultivars in 2005 was conducted in the faculty of agriculture, lorestan university. experiment, a split-plot randomized complete blocks design with four replicates were tested. treatments con...

background & aim: saffron is one of the expensive spices known since antiquity for its color, flavor and medicinal properties. saffron is the dried stigma of crocus sativus plant. the three basic components of the stigma on which the qualitative characteristics of saffron depend are crocin (color), picrocrocin (taste), and safranal (aroma). the quality of saffron is a function of climatic c...

Evaporation is a key parameter in the regional atmospheric water cycle. Precipitation recycling is defined as the contribution of water that evaporates from a region to precipitation within the same region. We apply a dynamic precipitation recycling model, which includes a dynamic moisture storage term, to calculate the warm season variability of the precipitation recycling over central Europe ...

introduction: vermicompost is one of the important bio-fertilizer which is the product of the process of composting different organic wastes such as manures and crop residues using different earthworms. vermicomposts, especially those are derived from animal wastes,contain the large amounts of nutrients compaired with the composts prepared from crop residues. vermicomposts contain plant availab...

Background: A substantial percentage of dog owners add water to dry dog food to increase its palatability. The recent association of Salmonella contamination of dry pet foods with salmonellosis cases in both dogs and their owners has generated a need to determine the ability of Salmonella to grow in eight commercial brands of rehydrated dry dog food. Results: Eight brands of commercial dry dog ...

Feeding shelled corn as the primary supplement in cracked dry form or ground high moisture form to grazing cows was studied in an experiment using 32 cows in late lactation. Each of the two forms of corn accounted for 74.7% of the concentrate supplement, which was fed at 9 kg/d (DM). The experiment was 13 wk, during which cows grazed permanent native pasture containing mostly grasses and some c...

The aim of the experiment was to determine the effect of different dry matter content and addition of silage inoculant on the ruminal protein degradability. Alfalfa herbage was collected from two cuts and the fresh matter was sampled two times during each cut (with different dry matter content). During the preparation of experimental micro-silages, the chopped forage was treated with a microbia...
