It is well known that the production of green feed is very important for the cultivation of farm animals. Green food actually plays a major role in feeding dairy animals. This type of feed provides essential nutrients for milk production as well as the health of dairy animals. Recently, more and more questions arise to the ecology of feed, the soils on which they grow. In Russia, the flagship of scientific research in this matter is the V. R. all-Russian Williams feed production research Institute (WFRI). Forage production, as a scientific discipline, is focused on the study of forage agro ecosystems. The article describes the new results of the Institute in the cultivation of environmentally friendly forage crops and seed propagation, production of field feed and pasture management. Results of research of ecological technologies for preservation and use of forages, technologies of grain-fodder production and utilization are resulted.
The using laser ablation of massive selenium targets, aqueous colloids of selenium nanoparticles were obtained. The resulting nanoparticles are monodisperse in size and mass. The paper presents the optical properties of nanoparticles, morphology and composition. It has been shown that selenium nanoparticles do not significantly affect the development of plants under reference conditions, but effectively level the effects of hyperthermia. The most effective concentration of selenium nanoparticles in the soil is a concentration of 10 μg / kg.
Researching the special and infraspecial structure in causative agent populations of the most dangerous diseases root rots of cereals in various regions of the Russjan Federation has been carried out. The defeat of cereals root rots old in Russia causes in the a complex patogenic. More often meet Fusarium culmorum (W.G.Sm.) Sacc., F. oxysporum (Schlecht.) Snyd.et Hans., F. heterosporum Nees., F. sporotrichiella nom.nov. Bilai F. gibbosum App.et Wr.emend Bilai., F. avenaceum (Fr.) Sacc. and Bipolaris sorokiniana (Sacc.) Shoem., Alternaria spp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
