Greenhouse experiment was carried out to study the effects of superabsorbent and water deficit stress on seedling growth of barley (Hordeum vulgare L.) in Urmia University of Iran. Three amounts of superabsorbent polymer (0 (S1), 2 (S2) and 4 g (S3) were mixed with 500 g soil before sowing, and four levels of irrigation regimes (irrigation at 20 (I1), 40 (I2), 60 (I3) and 80% (I3) field capacity) were set as treatments. The root length, root volume, root and shoot dry weight, plant height, leaf le… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
