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 ...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
abstract in order to investigate the effects of nitrogen fertilizer levels on the yield and quality of potato, (solanum tuberosum l.) a field experiment was conducted based on randomized complete blocks design with 3 replications in the research field of the college of agriculture, ferdowsi university of mashhad. nitrogen topdress fertilizer was applied in two levels of 100 and 150 kgn.ha-1 and...
The aim of this study was to examine factors affecting adoption of mini-tuber seed potato. Survey research design was used in this study. A sample of 100 potato growers who were informed about mini-tuber was selected and divided into adopter and non-adopter groups. Questionnaire was used as the instrument for data collection and was validated by a panel of experts. A pilot study was conducted f...
Abstract In Bangladesh, the third largest producer of potatoes in Asia, late blight, caused by Phytophthora infestans , is major constraint to production. Nevertheless, there a lack published information on pathogen population. A collection 69 isolates obtained from samples infected potato foliage collected 2018–2019 varied significantly their aggressiveness detached leaflets and tuber slices c...
given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

Sci., 46: 1-11. Plant pathogenic species Pseudomonas corrugata and P. marginalis were detected and determined in collapsed tomato plants in rockwool slab hydroponic culture in southern Moravia, Czech Republic...
Coping with water shortages without compromising tuber yield is a majorchallenge for potato (Solanum tuberosum L.) production in northern China. In thisstudy, we used three potato cultivars with different sensitivities to drought toevaluate the effect of long-term drought stress on morphological and physiologicalcharacteristics under field conditions during three growing seasons (2009-2011).Our...
