Effect of Levels of Phosphors and Zinc on Vegetative Growth of Wheat plant (Triticum aestivum L.)

Abstract

Plastic pots experiment was performed in greenhouse with Random Complete Block Design(RCBD) with three replications by using wheat plant (Triticum aestivum L.). Increase levels of phosphors fertilizer at a level of (0,150,300kg/ha.) as di-ammonium phosphate and zinc fertilizer at a level of (0,5,10kg/ha.) as zinc sulfate were added. Plant samples(vegetative part) were collected after 46days of germination. Plant height, leaf area, dry weight, concentration of organic materials (chlorophyll, protein and carbohydrate) and concentration of some elements (N,P,K) were determined. Results showed that the application of phosphors fertilizer caused a significant increase in all parameters mentioned above, but zinc sulfate application caused a significant increase in some of them. The interaction between two fertilizers was significant and the highest value of all studied parameters were found at treatment (300kgP/ha.+5kgZn/ha.). Key words : Wheat , Phosphor , Zinc .
