Chiko is an important tree fruit crop growing under semi-arid conditions. Kherol is mainly used as a rootstock for sapota which has seed germination problem. The shortage of irrigation water is one of the most important factors limiting agricultural production in arid and semi-arid areas. Irrigation with several dilutions of seawater can act as replacement water resource. Extensive studies have...

Some strawberriy cultivars (Fragaria x ananassa Dutch. cv. Aliso, Selva, Gaviota and Camarosa) were grown hydroponically with five NH4:NO3 mM concentration ratios (0/6 (S1), 0.25/6 (S2), 0.5/6 (S3), 1/6 (S4), 2/6 (S5) and constant nitrate concentration in three replicates for two seasons: Summer and Winter, in greenhouses of Agriculture Faculty of Tehran University. The results are reported as ...

Iron (Fe) and zinc (Zn) deficiency has been known as a key factor in limiting crop production in calcareous soils of arid and semi-arid regions. Since the components of organic matter can change Fe and Zn availability, this study was conducted to investigate the effects of humic treatments including humic acid (HA), fulvic acid (FA), vermicompost (Verm), HA+FA and HA+FA+Verm and mycorhiza inocu...

In order to evaluate the effect of different Trichoderma isolates on reducing the effects of drought stress on Polianthes tuberose, two factorial experiments were carried out based on completely randomized design with three replications. The first factor in the first experiment was bi isolate, and in the second experiment was isolate 65 of Trichoderma harzianum, each at three levels (0, 10, 20%...

Extended Abstract Introduction: The germination stage ensures the durability, establishment, and final yield of plants.  The final density of plants per unit area is resulted when the planted seeds germinate fully and with adequate rate. Plants mainly undergo abiotic stresses that are a considerable constraint for agricultural production worldwide. Seed priming is one of the simplest and cheap...
