Abstract :

To consider the original effect of irrigation limes, potassium fertilizer and determination of their reciprocal effect on phy[1]siology, morphology and physiology traits of Sorghum plant for cultivation plan in the best management and the most experimental in yield the pattern of split plot base on accident a full bloc for agricultural years 90-91,with three repetition at the form of imam Reza agricultural school located at Esferayen city. The research was conducted by four original cares of irrigation (first eastern, rising, irrigation of flowering phase, irrigation at the end of flowering phase ,irrigation to reach physiologic and the four sub ordinate cares obtained from potassium fertilizer (0.20.40.60 kg per Hectare). The average comparisons at fertilizer levels at any level of irrigation related to the Dounkene way indicated that each level on other factor level suggest us that each factor effect can be considers in fixed levels of other factor thus we would exactly esti[1]mate any factor level also in this research we used the third fertilizer level (40 kg per hectare) including each four distinc[1]tive phases for the study of experimental traits. In this study above characteristics were considered in high degrees. One of the well resulted traits was identified as a reciprocal effect related to irrigation at the end of flowering as well applying 40 kg per hectare of potassium fertilizer to obtain the panicool long.
