Abstract In most southern provinces of Iran, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce wheat yield, dramatically. To investigate the effect of sodium chloride on two wheat (Triticum aestivum L.) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a randomized complet...

abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...

Rice (Oryza sativa) is the primary food source for more than one-half of the world's population. Because rice cultivation is dependent on water availability, drought during flowering severely affects grain yield. Here, we show that the function of a drought-inducible receptor-like cytoplasmic kinase, named GROWTH UNDER DROUGHT KINASE (GUDK), is required for grain yield under drought and well-wa...

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

sericulture has played a very important role in the socio-economic empowerment of rural and semi-urban population. the eco-friendly nature of the industry, in addition to its employment generation potential, low investments and frequent returns, has rendered the industry as one of the most suitable land based economic activity, particularly in the context of global movement against environmenta...
