Milkweed allelopathy in the agroecosystem
Laboratory experiments were conducted to evaluate the allelopathic effects of different concentration (5, 10, 20, 30, 40, 50%) of Calotropis procera(Aiton) W.T. leaf aqueous extractusing different indices for germination, seedling and physical growth of wheat (Triticum aestivum) and black mustard (Brassica nigra). Except for germination speed, results indicated that the extracts have such allelopathic potential which can significantly reduce the ... Read more

Salinity tolerance in 280 genotypes of two-rows  Barley
In order to study salt tolerance of barley (_Hordeum vulgare _L.) genotypes in germination and field growth stages, laboratory and field experiments were carried out at the Agricultural Experimental Research Farm of Faculty of Agriculture, Sohag University, in 2005/2006, 2006/2007 and 2007/2008 seasons. This work aims to screen and evaluate barley genotypes under salinity conditions. Two hundred and eighty genotypes ... Read more

Assessment of Some Important Tree Species for Production under Arid Zones Conditions
This work aimed to investigate seed germination and growth of five tree species under water stress conditions of arid zones. Two separated experiments were carried out to assess their seed germination and water stress tolerance. The first one studied the effect of four seed treatments, including scarification, soaking in water, soaking in ethanol and control with no treatment, on the ... Read more
