Turions are frost resistant, vegetative dormant organs produced by aquatic plants. Tissue N, P, K, Ca, and Mg content was estimated in turions of 5 rooting, non-carnivorous plant species of the genera Caldesia, Hydrocharis, and Potamogeton and in 7 rootless carnivorous plant species of the genera Aldrovanda and Utricularia, and compared with concentrations of these nutrients in ambient waters e...
The vascular fusariosis is one of the main obstacles in tomato crop production. Currently, management nutrient solution presented as a control option for fusariosis, such reason different solutions with nitrogen (N), phosphorus (P), potassium (K) and calcium (Ca) modifications; four saladette varieties Bony Best (BB), Manapal (M), Walter (W) FLA were evaluated this research, order to analyze da...
Turfgrass nutrient uptake may be differentially affected by different salts. The objective of this study was to compare nutrient uptake in tall fescue (Festuca arundinacea Schreb.) as affected by carbonate, chloride, and sulfate under iso-osmotic, iso-Na+ strength conditions. 'Tar Heel II' and 'Wolfpack' cultivars were subjected to NaCl, Na2CO3, Na2SO4, CaCl2, NaCl+ CaCl2, Na2CO3+ CaCl2, and Na...
An experiment was conducted in Algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. Serum Ca, Mg and Na levels were significantly high at birth and decreases as the age advanced. The season had a significant effect on the decreased levels of Ca, Mg and K and inversely on the increased levels of N...
The aim of the study was to analyse quality soil in urban allotment gardens context production home-grown vegetables. conducted on six (31 individual plots) Gorzów Wielkopolski, a medium-sized Polish city with an average level industrialisation. following characteristics were analysed: pH, electric conductivity, organic matter, carbon, humus, total nitrogen, C:N ratio, NH4+-N, NO3-N?, P, K, Ca,...
ارزیابی وضعیت تغذیه ای چغندرقند با استفاده از روش dris و مقایسه آن با روشdop در استان آذربایجان غربی
به منظور تعیین اعداد مرجع و شاخص های dris در چغندرقند(beta vulgaris l.) و مقایسه آنها با شاخص های dop، 57 نمونه برگ از مزارع چغندرقند در استان آذربایجان غربی جمع آوری و غلظت های عناصر غذایی n، p، k، ca، mg، fe، zn، mn، cu و b تعیین شدند. مزارع با توجه به مقدار عملکرد به دو گروه مزارع با عملکرد بالا و پایین تقسیم شدند. نرم ها و شاخص های dris محاسبه و دامنه کفایت غلظت عناصر غذایی پرنیاز و کم نیاز...
Nutrient content and accumulation in mini lettuce as a function of fertigation management strategies
ABSTRACT Determining the amount of nutrients accumulated by crops is an important tool for defining order in which are taken up and required. However, vary depending on genetic characteristics cultivars, climatic conditions, fertilization, soil management systems. The aim this study was to evaluate influence irrigation strategies doses nitrogen (N) fertigation content accumulation macro micronu...
Conventional procedures are inadequate for optimizing the concentrations ofnutrients to increase the sugar yield. In this study, an artificial neural network(ANN) was used to optimize the Ca, Mg, N, K and Na content of the storage rootto increase sugar yield (Y) by increasing both sugar content (SC) and root yield(T). Data from three field experiments were used to produce a wide range ofvariati...
