Fertilization commonly increases biomass production in loblolly pine ( Pinus taeda L.). However, the sequence of short-term physiological adjustments allowing for the establishment of leaf area and enhanced growth is not well understood. The effects of fertilization on photosynthetic parameters, root respiration, and growth for over 200 d following the application of diammonium phosphate were i...

a randomized complete block design with three replications was performed in rice research institute of iran, rasht in 2008, to find the effect of supplement foliar application of nitrogen and potassium on ’daylam‘ hybrid rice grain yield, its components and grain protein percentage. foliar application of 20 kg nitrogen (5 percent n) and 15 kg potassium (3 percent k2o) in different pre-anthesis ...

This study was conducted in Abu-Khaseb –basra Province season 2010 to the effect of foliar fertilization by iron that spray chelated two concentrations (20 and 40 ppm) addition control treatment

Zinc deficiency is not only the cause of low productivity of crops, but it also results in low zinc content in seeds, which leads to poor dietary zinc intake. To study the effect of zinc foliar application on improving plant yield and seed zinc content for human consumption, chickpea plants were raised in refined sand culture with deficient (0.2 μM) and sufficient (1μM) supply of zinc under gla...

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on nutritional physiological parameters grain yield common bean. The experimental design was randomized block, in 2 x 5 factorial scheme. first factor site application fertilization. second doses: 0, 1, 2, 3, 4 kg ha-1 (6 replicates). following were evaluated: leaf nitrogen contents, relative chloro...

Foliar fertilization makes it possible to quickly supply plants with deficient nutrients, in case of both their deficiency the soil and hindered uptake. Crops are characterized by varying nutrient requirements for micronutrients, as well sensitivity deficiency. The paper presents practical aspects foliar feeding micronutrients using fertilizers, general classification characteristics. basic cro...
