Root-knot nematodes cause physiological and anatomical disorders in plants. The present study contains the results of an investigation of the effect of Meloidogyne incognita race2 on the growth of roots and aerial organs of tomato under greenhouse conditions. The experiment in a completely randomized design split split plot on two susceptible (Falat Y) and tolerante (Gina VF) tomatoes variety w...

Certain microorganisms in soil have phosphate solubilizing ability. Phosphorus has an important role in plant nutrition and N2 fixation in legumes. The interactive effect of three phosphate solubilizing bacteria (PSB) and Bradyrhizobium japonicum on yield and N, P, K uptake and nodulation of soybean root (Glycin max L. CV. Harcor) was studied under greenhouse conditions. In greenhouse experimen...

Due to low organic matter content in most of the cultivated soils of Iran and occurrence of drought stress in plants because of low precipitation, application of sewage sludge compost has been recommended for increasing soil organic matter content and improving soil fertility, increasing crop tolerance to water deficit and improving crop yield. So, in this study, the effects of soil moisture an...

To evaluate the effect of arbuscular mycorrhizal (AM) fungi (Glomus mosseae and Glomus intraradices) and Mesorhizobium Ciceri bacteria at three soil moisture levels [28% (field capacity, FC), 15% (-5 bar suction) and 9% (-10 bar tension) by weight] on morphological properties of root and aerial parts of chickpea, a greenhouse factorial experiment, arranged as a complete randomized design, was c...

To evaluate the allelopathic potential effects of giradol (Chrozophora tinctoria L.) organs on seed germination and seedling growth characteristics of watermelon (Citrullus lanatus L.), two experiments were carried out separately as a factorial in a complete randomized design with 4 replications; this study was carried out at Research Laboratory of Weed and Research Greenhouse of Faculty of Agr...

The effect of drought stress and mycorrhizal symbiosis on the colonization, root and leaf phosphorous content, root and leaf phosphatase activity, root volume and area as well as shoot dry weight of a variety of hulless barley were evaluated using a completely randomized experimental design (CRD) with 3 replications. Treatments were three levels of drought stress of 30, 60 and 90% field capacit...
