Research ArticleOpen accessIn the abstractComparison of Nonlinear Models for Dry Matter Yield of Brachiaria Hybrid cv Cayman in Drought Season by BootstrappingDanny Villegas Rivas, Nora Valbuena Torres, Manuel Milla Pino et al.The dynamics of biomass accumulation at different seasons of the year is of vital importance in the production of a forage species. In this study nonlinear models (logistic and gompertz) to describe growth dynamics of plants based on dry matter yield of Brachiaria hybrid Cayman at different interval between cuts in drought season were used. Results for logistic and gompertz … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 15 Mar 2021 · 6,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Carbon Source Screening Technology for Prevention and Control of Banana Fusarium WiltJin Li, Tingting Duan, Zhong Lin et al.With the spread of banana Fusarium wilt and the aggravation of the damage, it has become the biggest threat to the banana industry. Many studies have shown that bio-organic fertilizer plays an important role in the prevention and control of banana wilt, but most studies focused on biocontrol bacterium screening, not screening carbon sources that could prevent banana wilt, which … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 5 Mar 2020 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling the Evolution of Nitrate Pollution of Groundwater in the Plain of Western Middle CheliffNessrine Belmiloud, Naïma BettaharGroundwater constitute a potential source of drinking water supply and should, consequently, benefit from the necessary protection against the various forms of pollutions, particularly those diffuse of agricultural origin. The plain of Western Middle Cheliff which contains an important resource in groundwater supplying the whole population of the province of Chlef and contributing to the satisfaction of the need for … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 12 Jan 2016 · 7,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Wheat-Chickpea Intercrops as Influenced by Nitrogen and Weed ManagementA. Abdulahi, A. Dabbagh Mohammadi Nassab, S. Nasrolahzadeh et al.Wheat and chickpea are most important crops in dryland farming areas of Iran. Weeds have major impact on chickpea grain yield. This experiment was carried out to increase land use efficiency and weed suppression through intercropping in dryland agricultural research station-Sararood, Kermanshah, Iran during 2008-10. The experimental design layout was factorial split plot based on randomized complete block design with … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 4 Dec 2012 · 8,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Male-Sterility Mouse by Resection of the Tail EpididymisXianju Huang, Xuguang Wang, Xueshan Ma et al.Problem statement: Sterile males are bred with females to produce pseudopregnant recipients for oviduct and uterine transfers. Therefore, to make a sterile male mouse maybe the fist and fundamental procedure for embryo transfer. However, when people produce a sterile male mouse always abandon the sperm of the excellent male mouse. Approach: Here, the authrous present an efficient and simple procedure … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 18 Jul 2012 · 7,767 accessesView PDFCite

Research ArticleOpen accessIn the abstractPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Role of Sulfuric Acid In Production of Multicomponent Fertilizers From Renewable SourcesHelena Górecka, Henryk Górecki, Katarzyna Chojnacka et al.The paper discusses the possibility of using renewable sources: slaughter wastes and wood ashes in the production of NPK fertilizers. The content of macronutrients, micronutrients and toxic elements in these materials was reported.
