In the article are presented investigation results, which shows effectiveness of urea with urease inhibitor – nBPT in potato growing agroecosystems. The advantages new fertilizer yield increase, and quality improvement. Urea lead to formation bigger tuber size what is one most important characteristic for marketable potato. Fertilizer was tested experimental fields real farm conditions.

Bio-ethanol is one of the energy sources that can be produced by renewable sources. Waste potato mash was chosen as a renewable carbon source for ethanol fermentation because it is relatively inexpensive compared with other feedstock considered as food sources. However, a pretreatment process is needed: specifically, liquefaction and saccharification processes are needed to convert starch of po...

in order to study of yield and qualitative characteristics of potato (aola variety), an experiment was conducted in mashhad conditions under irrigation regims and different levels of potassium fertilizer. this experiment was based on randomized copmpletely block with split plot design with three replications in khorasan razavi agricultural and natural resource research center in 2010. three lev...

The effects of Bacillus thuringiensis subsp. tenebrionis applications and early harvest of potatoes on reducing the size of overwintering Colorado potato beetle, Leptinotarsa decemlineata (Say), populations in eastern North Carolina were investigated over 3 yr. In large-plot (0.04 ha) experiments, potato beetle densities and defoliation levels in plots that were either treated with B. thuringie...

ess as: A hnology Abstract This paper gives an overview of the wireless sensor network, studies its application in precision farming, and its importance for improving the agriculture in Egypt. An example for using wireless sensor network in cultivating the potato crop in Egypt is given, and it is shown that the cost of the system with respect to the yearly benefit from exporting potato crop aft...

Using Affigel Blue and oxamate-agarose affinity chromatography, lactate dehydrogenase (LDH) was purified 2000-fold from hypoxically induced barley roots. Molecular weights of the native and sodium dodecyl sulfate-denatured LDH protein were 157 and 40 kilodaltons, respectively, indicating a tetramer. Purified barley LDH was very similar in size and kinetic properties to potato LDH. However, thei...

The aim of this work was to research a bioprocess for bioethanol production from raw sweet potato by Saccharomyces cerevisiae at laboratory, pilot and industrial scales. The fermentation mode, inoculum size and pressure from different gases were determined in laboratory. The maximum ethanol concentration, average ethanol productivity rate and yield of ethanol after fermentation in laboratory sc...

Pectinolytic Pectobacterium spp. and Dickeya spp. are necrotrophic bacterial pathogens of many important crops, including potato, worldwide. This study reports on the isolation and characterization of broad host lytic bacteriophages able to infect the dominant Pectobacterium spp. and Dickeya spp. affecting potato in Europe viz. Pectobacterium carotovorum subsp. carotovorum (Pcc), P. wasabiae (P...

Cultivating resistant varieties of potato is the most effective and environmentally safe method of protecting against pests and diseases that affect potato crops. Therefore, potato breeding is focused on developing more resistant varieties so that the use of plant health products can be reduced during the cultivation cycle. Resistance to late blight, viruses and nematodes is the most important ...
