to evaluate the effects of phosphorous, iron and zinc fertilizers on quantity and quality of turnip, a field experiment was conducted in 2009. the experiment treatments arranged as split plot factorial based on a completley randomized design with 4 replications in the research farm of the university of tehran (karaj-iran). the main factor including three levels of phosphorous (super phosphate t...

A pot experiment was conducted to examine the effects of.various fertilizers on the dynamics of soil-borne DDTs and their subsequent impacts on DDTs uptake by a test plant. The results show that there was a significantly lower soil residual DDTs concentration in the iron-rich fertilizer-treated soil than in other fertilizer-treated soils. However, all the non-iron-rich fertilizers showed no sig...

to evaluate the effect of nano-iron chelate and also to make a comparison with effect of eddha iron chelate on saffron, an experiment was conducted as factorial based on a randomized complete block design with six treatments and three replications in shahed university, tehran in 2011 and 2012. treatments included iron fertilizer (nano chelate and common chelate) in three levels (zero, 450 and 9...
