One of the objectives of conservation agriculture to reduce soil erosion in olive orchards is to protect the soil with cover crops between rows. Andalusian and European administrations have developed regulations to subsidise the establishment of cover crops between rows in olive orchards. Current methods to follow-up the cover crops systems by administrations consist of sampling and on ground v...

Funding Request: No funding is requested. We are not continuing this project because of the current low level of the disease in most commercial orchards and lack of interest in the industry in funding a full program on this disease. However, as the acreage of new plantings increases, particularly those susceptible varieties, bacterial canker can be an important factor in the process of establis...

Apple is a fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the culture. Many of the efforts and costs for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the fungus Venturia inaequalis. The economic impac...

Despite a favorable business model, genomic selection is still not a popular tool for genetic improvement of Nelore cattle in Brazil mainly due to the lack of a costeffective strategy for its application. Different independent Nelore breeding programs have already developed prediction equations for usual and difficult/expensive to measure traits. Unfortunately, some programs are using genomic p...

Genetics significantly influences the immune system, and the genotypic structure of modern fast-growing chickens has been changed, particularly after decades of breeding for higher production. Therefore, this study was designed to help determine if intensive breeding progr...
