Host nutritional variables were evaluated for their effects on the severity of crown and root rot of tomato caused by Fusarium oxysporum f.sp. radicis-lycopersici. Tomato (Lycopersicon esculentum Mill.) seedlings (cv. Bonnie Best) were grown in a pathogeninfested, soilless rockwool system in the greenhouse and were fertilized with a nutrient solution that was amended with macroand microelements...

Problem statement: Recently a particular attention was paid to the issue of microelement hunger, also termed hidden hunger. The problem was of global significance, since was related with the public health and concerns over 2 billion people. Approach: The study discusses the state of the art in the research on food biofortification as the sustainable solution to cope with micronutrient deficienc...

In 2020 and 2021, a block trial was conducted with two herbicide preparations four foliar feeding products for maize. The studies were carried out maize, hybrid Knezha 509, grown under non-irrigated conditions after wheat predecessor. effect of the combined application Stomp new 330 EK Hemniko 24 SK microelement fertilizers Amalgerol, Vertex high N-34 Foliar extra studied. influence studied tre...

With a large and growing demand in the market, rapeseed (Brassica napus subsp. napus.) is crop with relatively high requirements for macronutrient fertilization. The aim of experiment was to study effect mineral fertilization different doses nitrogen phosphorus on accumulation microelements vegetative organs grains oilseed rape plants.The carried out long-term experimental fields SCDA Livada. T...

nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

INTRODUCTION Selenium is generally recognized as an important antioxidant with numerous biological functions. In spite of intense research during recent years, the role of this microelement needs further elucidation. We therefore decided to use the sodium fluoride (NaF) model of chronic intoxication in rats to determine whether selenium is able to prevent some of the accompanying biochemical ch...

in order to study concentrations of soil micro and heavy metal elements in some saffron planting regions of birjand province, an experiment was performed as factorial layout based on a completely randomized block design with three replications at year 2013. treatments were three field ages (annual, triennial and quinquennial) and five saffron regions including aryan shahr, hosseinabad, khosef, ...

This chapter provides information on some recent developments of fertilizer production and use that improve nutrient efficiency and minimize environmental impact. The nutrients discussed are mainly N, P, and S. Improving N nutrient efficiency includes use of (1) controlled-release coated urea products, (2) slowrelease urea–aldehyde polymer products, (3) urea supergranules for deep placement, (4...
