To study the effect of nitrogen, salinity and organic matter on growth and root morphology of pistachio (Cv. Badami), a greenhouse experiment was conducted. Treatments consisted of four nitrogen (N) levels (0, 60, 120 and 180 mg kg-1 soil as urea), four salinity levels (0, 800, 1600 and 2400 mg NaCl kg-1 soil) and three organic matter (OM) levels (0, 2 and 4% soil as farmyard manure). Treatment...

Salinity and waterlogging are two important abiotic stresses to plants growth and yield in the world. These two stresses can occur simultaneously and have additive effects on plants, including corn, growth. In a greenhouse experiment, the effects of NaCl salinity and waterlogging and their interactive effect on the growth characteristics of forage corn (Zea mays cv. single cross 704) were studi...
Symbiotic effect of twenty one indigenous Bradyrhizobium yuanmingense strains obtained from nodules of soybean cultivated in India was comparatively evaluated with B. japonicum ASR011 on soybean cv. JS335 for improved nodulation and plant growth performance under greenhouse conditions. Significant variation in symbiotic potential among native B. yuanmingense strains was observed and few of them...
To investigate the effect of cadmium (Cd) on some physiological parameters of safflower genotypes a 3-replicate factorial randomized complete blocks experiment was conducted under hydroponics culture in greenhouse facilities of the Isfahan University of Technology in 2012. Four levels of Cd (control (0), 1.5, 3.0 and 4.5 mg/L) were tested on six safflower genotypes (Arak2811, Kouseh, Nebraska...
Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...
In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...
BACKGROUND AND AIMS Growth of bedding plants, in small peat plugs, relies on nutrients in the irrigation solution. The object of the study was to find a way of modifying the nutrient supply so that good-quality seedlings can be grown rapidly and yet have the high root : shoot ratios essential for efficient transplanting. METHODS A new procedure was devised in which the concentrations of nutri...
The objectives of this work were (1) to screen large collection of bean genotypes for salinity responses and (2) to identify the best traits for screening the bean germplasm in tolerance to salt stress. Sixty-four bean genotypes were subjected to 125 mM NaCl. Plants were grown in hydroponic growing medium in greenhouse. The screening was carried out at early growing stage (25 days old plant). I...
in order to study the morphological characteristics affecting yield of echium amoenum under different nutritional treatments and different plant densities, a factorial experiment based on rcbd design with three replications was conducted at agricultural research station, ferdowsi university of mashhad, iran in 2011-2013 growing seasons. the experimental treatments were all combination of three ...
