【 摘 要 】

In order to evaluate yield andsome of physiological indices of potatocultivars in relation to different kinds ofmanures, strip plot layout within arandomized complete block design withthree replications was used. Three levels offertilizer were included manure (t/ha) (20,40 and 60 t/ha), biologic fertilizer (ml/ha)(0, 100 and 200 ml/ha), and chemicalfertilizer (kg/ha) (175, 350, and 525 kg/ha).Cultivars were Marfona, Maradona andRamus. Marfona had obtained the maximumplant height, total dry matter, LAI, tuberyield, dry matter of tuber, the number oftuber and tuber weight. Application of60 t/ha manure fertilizer together withMarfona produced the highest yield. In thisexperiment, fertilizer showed significanteffects on potato cultivars yield andphysiological indices. Marfona and Ramushad obtained the highest and the lowest totaldry matter, respectively. The maximum LAIwas related to application of 60 t/ha manurefertilizer, and the minimum one wasobtained for application of 40 t/ha manurefertilizer. In cultivar treatments, the highestLAI was obtained for Marfona, followed byMaradona and Ramus. The maximum andthe minimum crop growth rate (CGR) wasrelated to chemical and biological fertilizer,respectively. The maximum CGR wasrelated to Marfona, than those of othercultivars. There were not any significantdifferences among different fertilizers in netassimilation ratio (NAR), fertilizer levelsand various cultivars. Thus, it can vesuggested that in order to increasing yield,total dry matter, crop growth rate and otherphysiological indices should be applied60 t/ha manure fertilizer with Marfonacultivar in Fereydan region of Esfahan, Iran.
