Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...

one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...

Production of high sunflower yield is important in sunflower breeding programs. With regards to the importance of estimation of general combining ability (GCA) and specific combining ability (SCA), genetic evaluation of sunflower seed yield was carried out in normal and water stress conditions using biplot analysis of 6×6 diallel design. Parental lines and their progenies were investigated usin...

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Extended Abstract Introduction and Objective: The selection of high-yielding genotypes is especially important in sunflower. Therefore, this study was conducted to identify interrelationships between different traits and the selection of the best sunflower hybrids. Material and Methods: In this study, 11 new hybrids along with four cultivars Golsa, Ghasem, Shams, and Farrokh were evaluated in...
