Sen2-Agri is a software system that was developed to facilitate the use of multi-temporal satellite data for crop classification with random forest (RF) classifier in an operational setting. It automatically ingests and processes Sentinel-2 LandSat 8 images. Our goal provide practitioners recommendations best sample size composition. The study area located Yaqui Valley Mexico. Using polygons mo...

sugar beet is one of the major products in qazvin plain that allocated most of planting areas to itself after wheat, barley and corn. in recent years, restriction on water resources decreased sugar beet planting area in this plain. therefore, in this study, the effects of increase in sugar beet planting area on planting pattern, grower's gross profit, and inputs utilization under water sho...

Three 2.4-ha wheat (Triticum aestivum L.) fields were used to test the effects of maturity at harvest (boot vs. dough) and preservation method (hay vs. silage) on forage yield, chemical composition, and animal performance when fed in mixed diets. Forages were incorporated into 4 diets in a 2 x 2 factorial arrangement of treatments with hominy feed, soybean hulls, and cottonseed meal as the prim...

Arthropods are mobile, and often move beyond the classical bounds of ecological field studies. We have done landscape analyses to explore the influence of the surrounding landscape on spiders in winter wheat fields and on their potential to control cereal aphids. The densities of many spider species were enhanced by high percentages of non-crop habitats at scales ranging from 95 m to 3 km radiu...

The antioxidative activities of durum wheat flour and its components on linoleic acid were examined at 50 degrees C and 12% relative humidity. The progress of the oxidation was monitored by the pressure change due to the oxygen consumption during the oxidation. The antioxidative capacities were assessed by the length of the induction period for the oxidation. Durum wheat flour and its methanol ...

Bread wheat (Triticum aestivum) is a hexaploid species with A, B, and D ancestral genomes. Most bread wheat genes are present in the genome as triplicated homoeologous genes (homoeologs) derived from the ancestral species. Here, we report that both genetic and epigenetic alterations have occurred in the homoeologs of a wheat class E MADS box gene. Two class E genes are identified in wheat, whea...
