In order to study effect of phosphorus fertilizer and micronutrients foliar application on yield sorghum, a field experiment was conducted in at 2011 in Research Farm of Payame Noor University of Zahedan, Iran. This experiment was done as split plot Based on randomized complete block design with three replications. Experiment treatments included: micronutrients foliar application containing elements (Fe + Zn + Mn) and control (without micronutrients foliar application) as main plots and four levels of phosphorous fertilizer: 50, 100, 150 and 200 kg/ha as sub plots. The results showed that Effect of micronutrients foliar application was significant on plant height, length of flag leaf, grain yield and biological yield. Phosphorus fertilizer had significant effect on yield and grain weight, so that the highest amount of these factors obtained from 200 kg/ha treatment. These results indicated that application of phosphorus fertilizer with micronutrients foliar application is a useful method for yield increase of sorghum.
