background and objectives: soybean (glycine max l.) is the most important oil crop having the largest area under cultivation in the world. every year, water stress causes great damages on crops in the world, particularly in iran with arid and semi-arid climate so application of materials such as zeolite in soil can reduce the adverse effects of water stress. however, the effect of zeolite in in...

Gamma-linoleic acid in the seed oil of evening primrose makes it nutritionally and pharmaceutically valuable. If evening primrose wants to be cultivated as an annual plant, sowing time is important. By the late sowing and depends to time most plants do not produce flower stem and stay in rosette stage until next spring. To solve this problem, the present study was performed. Seedling were trans...
