Uptake Nitrogen as Affected by Various Combinations of Nitrogen and Phosphorus

Growth and nitrogen content of sunflower as affected by the rate and form of nitrogen

Yield and chemical composition of 'Piarom' Date-Palm Phoenix dactylifera as affected by nitrogen and phosphorus levels

Extraordinary importance of Date-Palm, Phoenix dactylifera especially ‘Piarom’ variety and also undeniable effect of nitrogen and phosphorus on yield and quality of this product, caused this research to be accomplished. The research was performed during two years on 72 (4*3*3*2=72 trees) fruitful, 12 years old trees in Hormozgan province. Treatments were consisted of four levels of nitrogen (0,...

Yield and nitrogen uptake of soybeans and safflower plants grown on alkaline soil as affected by iron chelate, CCC and nitrogen

Coral Uptake of Inorganic Phosphorus and Nitrogen Negatively Affected by Simultaneous Changes in Temperature and pH

The effects of ocean acidification and elevated seawater temperature on coral calcification and photosynthesis have been extensively investigated over the last two decades, whereas they are still unknown on nutrient uptake, despite their importance for coral energetics. We therefore studied the separate and combined impacts of increases in temperature and pCO(2) on phosphate, ammonium, and nitr...

N uptake and yield of wheat as influenced by integrated use of organic and mineral nitrogen

The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil in Nuclear Institute for Food and Agriculture, Tarnab, Peshawar Pakistan during 2005-07. Combined dose of N provided from all sources was applied @120 kg ha-1. There were 17 ...
