Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...

Coating of particulate solids by a thin film layer is of interest in many industrial applications such as seed and tablet coating. In seed processing, seeds are commonly coated with a protective coating layer consisting of fertilisers and crop protection products. Rotary drum batch coaters are typically used for this purpose. The coater consists of a cylindrical vessel with a rotating spray dis...

BACKGROUND: Bio-fertilizers are best eco-friendly approach for plant and soil environment. Also, micronutrient element such as iron plays a key role in the formation of chlorophyll and photosynthesis. OBJECTIVES: This study evaluated the effect of growth bacteria and Nano iron fertilizer and ordinary iron fertilizer on some physiological properties of Tritical...
