Journal Title: International Research Journal of Applied and Basic Sciences - Year 2016, Vol 10, Issue 5
Abstract
This factorial experiment within a randomized complete block design with 4 replications was conducted to examine the effect of foliar application of Iron, zinc, and selenium on nutrient uptake and yield of alfalfa under rainfed conditions in Aligoudarz, Iran. The treatments of the experiment included the iron at 3 levels: the control (non-use of iron), iron sulfate at the concentration of 3/1000, and completely liquid iron 5%; zinc at 3 levels: the control (non-use of zinc), zinc sulfate at the concentration of 3/1000, and completely liquid zinc 5%; and selenium at 2 levels: the control (non-use of selenium) and sodium selenite at the concentration of 20 g/ha. The results of data variance analysis showed that the effect of foliar spray of iron, zinc, and selenium was significant on all properties at significance level of 1%. Maximum yield of alfalfa was 3506.2 kg/ha obtaining from the treatment with iron sulfate at a concentration of 3/1000 + zinc sulfate at a concentration of 3/1000 + 20 g of selenium per hectare, which showed an increase of 34% as that in the control treatment. Moreover, results showed that the foliar spray considerably increased the uptake of iron, zinc, and selenium in plants.
