the higher levels of essential elements in soil may be caused in optimum yields and crop quality. so it seems to be necessary to examine different levels of nutrients like fe and zn on plants and their productivity. to evaluate effects of iron and zinc application on yield and yield components of pimpinella anisum an experiment was conducted at the research farm of urmia university in 2009. tre...

abstract- to evaluate effects of different soil moisture conditions namely, phosphorus (p) and zinc (zn) application, on extractable zn and fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. the first experiment was performed with the following factors; incubation time at four leve...

this research carried out in the rafsanjan pistachio orchard to investigate the effect of n form, manure, k and fe on yield, nut quality and leaf mineral nutrients concentrations of pistacia vera l. cv. fandoghi grafted on badami-riz zarand rootstock. the experiment was as factorial with four factors including; manure (without manure and 10 kg tree-1 sheep manure), n form (ammonium sulfate and ...
