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 abstractTHE EFFECT OF AGRICULTURAL EXTENSION SERVICE ON THE TECHNICAL EFFICIENCY OF TEFF (ERAGROSTISTEF) PRODUCERS IN ETHIOPIAAsres Elias, Makoto Nohmi, Kumi Yasunobu et al.Teff (Eragrostistef) is a major staple food crop in Ethiopia, but smallholder teff production is characterized by persistently low average yield. A major government effort aimed at raising the productivity and competitiveness of smallholder agriculture in Ethiopia involved reforming and implementing agricultural extension service known as Participatory Demonstration and Training Extension System (PADETES). Therefore, this study investigates the effect of … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 21 Dec 2013 · 9,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Genetic Diversity among Sugarcane Cultivars (Saccharum officinarum L.) using Simple Sequence Repeats MarkersAshutosh Pandey, Rupesh K. Mishra, Shashank Mishra et al.Problem statement: Increasing sugar productivity is the main concern of sugarcane (Saccharum officinarum L.) breeding programs. The complexity and size of the sugarcane genome is a major limitation in its genetic improvement. Characterization of sugarcane provides essential information of genetic diversity for breeders utilize for crop improvement. Approach and Results: The objective of this study was to evaluate the microsatellite … …OnLine Journal of Biological Sciences, Vol. 11, Issue 4 · 27 Jan 2012 · 7,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Compaction and Oil Palm (Elaeis guineensis) Yield in a Clay Textured SoilZuraidah Yahya, Aminuddin Husin, Jamal Talib et al.Problem Statement: The impacts of soil compaction on crop yields have been studied extensively by soil scientists due to declining soil productivity associated with mechanisation. However, a relationship between machine-induced soil compaction and oil palm (Elaeis guineensis) yield is unclear. Therefore, the objectives of this study were to determine the effects of mechanization on soil physical properties and the influence … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIsolation and Culture of Oocytes from Dairy Cows' Ovaries for Productivity in the Southeastern Region of KazakhstanDauren Maratovich Bekenov, Batyrkhan Azimkhanovich Buralkhiev, Yusupzhan Artykovich Yuldashbayev et al.This research work aims to study methods for isolating and culturing follicular oocytes from Holstein cows in vitro. The proven complex of technologies for embryo transplantation on an industrial scale will provide a 3-5-fold acceleration of reproduction of highly productive cows. As a result of scientific research, biotechnological methods of accelerated reproduction of dairy cattle have been substantiated and introduced … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 14 Oct 2024 · 4,298 accessesView PDFCite
