In this paper, to account for the effect of water stresses in the various growth stages under deficitirrigation, the multiplicative, seasonal and minimal approaches are integrated in the BUDGETmodel. To evaluate the model, the simulated yields for winter wheat (was grown in Sharif Abaddistrict) under various levels of water stress were compared with observed yields. The resultshowed, simulated ...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...

In 1996, an effort began to quantify soil water storage, crop use, and productivity on dryland systems in western Kansas. Research 4-year rotations with wheat grain sorghum was initiated at the Southwest Research-Extension Center near Tribune, KS. Rotations were wheatwheat- sorghum-fallow (WWSF), wheat-sorghum-sorghum-fallow (WSSF), continuous (WW). Soil planting averaged about 9.1 in. followin...

Information on crop yield at scales ranging from the field to global level is imperative for farmers and decision makers. The current data sources monitor yield, such as regional agriculture statistics, are often lacking in spatial temporal resolution. Remotely sensed vegetation indices (VIs) NDVI able assess using empirical modelling strategies. Empirical NDVI-based models were evaluated by co...

to identify important attributes/factors that contribute to grain and biological yields of wheat, 9912 sets of diverse data from field studies were extracted, and supervised attribute-weighting models were employed. results showed that when biological yield was the output, grain yield, nitrogen applied, rainfall, irrigation regime, and organic content were the most important factors/attributes,...

Crop diversification and integration of livestock into cropping systems may improve the economic and environmental sustainability of agricultural systems. However, few studies have examined the integration of these practices in the semiarid areas of the Northern Great Plains (NGP). A 3-yr experiment was conducted near Bozeman, MT, to compare the effects of crop rotation diversity and weed manag...

BACKGROUND The recent development of improved enzymes and pentose-using yeast for cellulosic ethanol processes calls for new attention to the lignocellulose pretreatment step. This study assessed the influence of pretreatment pH, temperature, and time, and their interactions on the enzymatic glucose and xylose yields from mildly pretreated wheat straw in multivariate experimental designs of aci...
