awardness about structure of production technology and its characteristics is a usefull tool for planning in agricultural sector. in this regard, this study aims to determine some effective parameters of structure of production technology in rain fed barley production. before estimating these parameters, we examine the aggregation consistency condition for barley fields using the mean scaling t...

in order to investigate the effective factors on the reduction of rain-fed wheat yield, an experiment in 45 fields was conducted in the township of bandar-gaz in 2012. in this research, all information such as crop management operations, seedbed preparation, cultivar, site preparation, seed sowing, weed combating, planting and harvesting issues, time of toxicant spraying, used seed rate were co...

The interaction of maternal photoperiod history and four diets were tested by measuring body growth, reproductive development, and pelage development in 9-week-old juvenile meadow voles. Meadow vole dams were housed in long daylengths (LD; 14 h light/day), short daylengths for 2 weeks (SD; 10 h light/day), or short daylengths for 26 weeks (PR; photorefractory) prior to mating. Immediately follo...

To test the hypothesis that inclusion of whole cereals in the diet of broiler chickens reduces the severity of a coccidial infection, the effects were investigated, in birds infected with Eimeria acervulina, of feeding a complete pelleted control food, the control food diluted with whole wheat (400 g/kg), or a diet in which ground wheat in the pellets was substituted with whole wheat (400 g/kg)...

Wheat based products are consumed as staple food in most the of Asians countries, hence different wheat cultivars purposely developed to meet diverse ecological conditions. These carry difference their rheometry nutrition and gluten microstructure that affect overall product quality. In present investigation ten varieties were selected from two common zones i.e. rain fed irrigated. general, non...

Rainfed farming is a dominant agricultural system in Tigray, Ethiopia. However, rainfall characterized by short duration, intense and erratic subjected to late-onset early cessation, suggesting pressing need for Supplemental Irrigation (SI) fill the crop water demand. Understanding effects of SI during late-onset, or both, along with their underlying causes, critical knowledge gap globally. Alt...

Abstract Identifying the future threats to crop yields from climate change is vital underpin continuous production increases needed for global food security. In present study, vulnerability of European wheat yield heat and drought stresses around flowering under was assessed by estimating 95-percentiles two indices at rain-fed conditions: stress index (HSI95) (DSI95). These represent relative l...

Drought is one of the most devastating climate extremes in terms its spatial extent and intensity. Rainfed areas are extremely vulnerable to drought, but effective monitoring may lessen impact such events. This study developed a composite drought index (CDI) for assessing seasonal droughts rainfed Potwar Plateau Pakistan, using remotely sensed observed meteorological datasets. We identified fou...

Twelve crossbred steers (351 +/- 24 kg initial BW) were used to determine effects of high-Se wheat on visceral tissue mass, intestinal cell growth, and intestinal cellularity and vascularity. Steers were allotted randomly by BW to one of two treatments consisting of 75% concentrate diets that supplied 1) adequate Se concentration (7 to 12 microg x kg x BW(-1) x d(-1)) or 2) high-Se concentratio...
