Because of limiting water resources and increasing demand for food, it is necessary to investigate the effect of irrigation systems on water productivity. This research was conducted to evaluate yield and yield characteristics of two potato varieties under sprinkler and trickle irrigation systems. The treatments were two irrigation systems (sprinkler and trickle irrigation) and two potato varie...

in order to evaluate of yield and yield components of chickpea genotypes, path analysis set to facilitate the selection of high yielding varieties in limited irrigation. research was canducted in 2010-2011 growing season at the agricultural research station, ferdowsi university of mashhad, by using seven drought tolerante genotypes (recommended from a previous research) in a randomized complete...

In order to evaluate the effect of deficit irrigation and different types of potassium fertilizers on improving the photosynthetic pigments content and chlorophyll florescence parameters in rice (cv. Tarom Hashemi), two field experiments were conducted in the Rice Research Institute (Amol) and model farm located in Savadkouh in a split plot based randomized complete block design with three repl...

Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...

     Nowadays, the root characteristics as one of secondary traits along with grain yield are used to response evaluation of rice genotypes under deficit irrigation. Thus, to evaluate the root traits of 40 irrigated rice genotypes to water limited condition a pot experiment was performed in 2014 at Rice Research Institute (Rasht), Iran. Irrigation treatment was applied in two levels include con...
