Title
Evaluation of phosphorus use efficiency in wheat cultivars
Authors
Abstract
Abstract
In order to assess the efficiency of phosphorus in wheat cultivars in greenhouse pot experiment was conducted Azad University, BOJNURD the 1391-1390 crop year . Phosphorous fertilizer levels (control (no fertilizer) , 50 % and 100 % recommended fertilizer recommendations Cody ) and figures ( homeland , leading , and Pioneer Network ) , a factorial experiment in a completely randomized design with four replications. Varieties in terms of yield, agronomic efficiency of fertilizer utilization efficiency of phosphorus fertilizer and phosphorus fertilizer rates showed no significant difference at 1% level . Results showed that the highest yield of 100 % of the recommended amount of phosphorus in the homeland and the lowest figure of the Persian yield without fertilizer phosphorus control , respectively. Thus the English varieties as efficient varieties are recommended for conditions of phosphorus limitation
