Abstract
Under field production phase, wilt, stalk and tuber rots diseases lead to considerable decline in Jerusalem artichoke (JA) yield and quality, and subsequently reduce storability of tubers. This study aimed to test and prepare suitable formula for increasing yield, quality and storability of JA tubers, through controlling the causative pathogens; Sclerotinia sclerotiorum and Rhizoctonia solani. Among Arbuscular mycorrhizal fungi (AM), Trichoderma species (T) and hydroquinone (HQ), the combined application of AM+HQ, followed by AM+T reduced the disease incidence under greenhouse and field conditions, improved yield and enhanced the tuber quality (dry matter, total carbohydrates and protein). This in turns reasonably increased the storability parameters (decay, weight loss, dry matter and inulin content) during storage of JA tubers. So, such applications may introduce integrated solutions for field and storage problems of JA tubers.
