In this study, plant height and plant dry weight of five wheat varieties (namely Da da 94, K nac 97, Konya 2002, Karahan 99 and Ahmeta a), collected for 20 weeks, were modeled via fitting generalized logistic (GLC), logistic (LC) and Gompertz (GC) growth curves. Growth curve selection was based on residual sum of square (RSS) and mean square error (MSE). Following growth curve selection, growth...

Wheat and high-moisture corn (HMC) were fed singly and in three combinations using dry-rolled wheat (DRW) (ratios of 75:25, 50:50, and 25:75, respectively, Trial 1), or singly and in two combinations using steam-rolled wheat (SRW) (ratios of 67:33 and 33:67, respectively, Trial 2) to finishing beef cattle fed a high-concentrate diet. In situ rate of starch digestion (Trial 3) was measured on gr...

one of the effective tools for identifying land resources and assign them to the best and most profitable forms of land productivity, susceptibility of agro-ecological zoning . in this study agro-ecological zoning of satellite imagery and gis were used. after agro-climatic zoning (based on isorain, isothermal and length of growing period maps) and agro-edaphic zoning (based on soil, slope and l...

Land surface evapotranspiration (LET) from typical river basins in China in the years 1991, 1995 and 1999, was modelled with a quantitative remote sensing method, which is based on a modified version of the Surface Energy Balance System (SEBS) model. LET simulations were conducted on several river basins, and validations demonstrated good agreement with observational data on all basins, except ...

An experiment was carried out to examine the effects of feeding Fusarium toxin-contaminated wheat (8.21 mg deoxynivalenol (DON) and 0.09 mg zearalenone (ZON) per kg dry matter) at different feed intake levels on the biotransformation and carry-over of DON in dairy cows. For this purpose, 14 ruminal and duodenal fistulated dairy cows were fed a diet containing 60% concentrate with a wheat portio...

This study was conducted to investigate the effect of biological treatment withPleurotus floridafungi on chemical composition and rumen dry matter (DM) and organic matter (OM) degradability of wheat and barley straw. Wheat and barley straw were collected from Golestan province of Iran and after pasteurization mixed with fungi spawn (than 5% by weight). After 21 days samples were dried in oven (...

We determine the vegetation type for the CART from a database generated by the U. S. Geological Survey (USGS 1990). Soil types were provided by the Atmospheric Radiation Measurement (ARM) Program from the State Soil Geographic (STATSGO) database and mapped into the USDA classifications described by Clapp and Hornberger (1978). To provide the input parameters of temperature, pressure, humidity, ...

intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

degraded soils in northwest china are mostly nonproductive due to imbalanced nutrient and inadequate water supply. the effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha–1) combined with chemical fertilizers on soil water and water-use efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark loessial soil and over a per...
