in order to evaluate effects of iron, zinc and manganese, and the methods of applying them on yield and yield components of sweet corn (zea mays saccharata), an experiment was performed as factorial based on randomized complete block design with four replications at the research farm of urmia university. experimental factors were micronutrient fertilizers with four levels (control, iron, zinc a...

A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...

Kiwifruit requires a high quantity of nutrients that must be supplied through fertilization to obtain an optimum yield on a sustainable basis. This research was conducted to evaluate different fertilization methods including broadcast application (as control), deep placement of the fertilizer and fertigation, alone or in combination with foliar application and their effects on the yield, leaf m...
