Abstract Noug ( Guizotia abyssinica (L.f) Cass) is an important edible oil-producing crop. Ethiopia the center of origin and diversity for noug thousands accessions are being maintained at Gene Bank in Ethiopian Biodiversity Institute (EBI). The crop grown mainly oil by-product named as noug-cake widely used animal feed. However, production productivity too low compared to other oilseed crops d...

An increase in world population requires growth food production. Wheat is one of the major crops, covering 21% global needs. The supply issue necessitates reliable mathematical methods for predicting wheat yields. Crop yield information necessary agricultural management and strategic planning. Our model was developed based on a three-year field experiment semi-arid climate zone. yields ranged f...

To gain perspective on alfalfa-annual crop rotations in the upper Midwest, USDA-National Agricultural Statistics Service cropland data layers and Soil Survey Geographic Database layers were combined for six states (North Dakota, South Dakota, Nebraska, Minnesota, Iowa, and Wisconsin) and seven years (2006-2012). Soil texture and geographic location both significantly affected the length of the ...

In order to simulate growth and yield of crop in field scale, crop simulation models always require a lot of initial parameters. WebGIS is a powerful tool for obtaining, managing and analyzing spatial data on the Web. With the support of WebGIS, crop models based on web services can be easily run on the web by remote client and provide decision information and measures for crop production. In t...

Exotic germplasm refers to crop varieties unadapted to a breeder’s target environment, and is an important resource for crop improvement. Because genetic diversity within elite cultivars of a crop is limited compared to the variability within the species and its relatives worldwide, genes from exotic germplasm can protect the crop against new biotic and abiotic stresses, and may represent uniqu...

Domestication has resulted in selection upon seed traits found in wild populations, yet crop-wild hybrids retain some aspects of both parental phenotypes. Seed fates of germination, dormancy, and mortality can influence the success of crop allele introgression in crop-wild hybrid zones, especially if crop alleles or crop-imparted seed coverings result in out-of-season germination. We performed ...

This paper proposes a web-based Agro-Information System (AIS) prototype that can support farmers with agricultural-related information about a given food crop. Consistency in the application of this information can help in improving crop yield, in controlling crop pests, in crop diseases treatment, and in enhancing the overall crop productivity. A prototype AIS capable of providing possible pes...
