Abstract
Crop sorghum enjoyed by the possibility of grains harvested more than once from planting one (this is known as Ratoon) in relation to the grains varieties. The date of harvest of sorghum in the spring is the later planted in the autumn season making conditions favorable for the application of cultivation ratoon. As the plants resulting from ratoon sorghum will change their requirements for nutrients because of branching, most important of those elements nitrogen, among the nutrients needed by plants in large quantities outweigh the rest of the other nutrients, and other elements important element potassium, which need to plant outweigh the need for any of the nutrients other than nitrogen, has its major role in the transport, storage and representation. Therefore, this study aimed to know the performance ratoon sorghum under the influence of nitrogen and potassium fertilizers. Carried out in the fields of research station Abu-Ghraib, Agricultural Research Office, during the spring and autumn seasons for 2012 factorial experience and according to the RCBD design with three replications. Using levels of fertilizer Naatroyjana (160, 200, 240 and 280) kg N.H-1 and levels of fertilizer potassium (0, 120, 160 and 200) kg K.H-1. Results showed that holds grain influenced significantly with increasing nitrogen fertilizer and potassium and interactions. The fertilizers effect in 1000-grain weight, biological yield and harvest index was significantly increased with the addition fertilizers individually, and there are no interaction significant effect on those qualities.
