intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

The relationship between phosphorus (P) uptake and growth rate of chrysanthemum plants grown hydroponically for cut flowers was investigated. In Exp. 1, fresh weight increase of chrysanthemum cv. Seiun plants at flower budding phase administered 0 to 40 ppm in culture solution for 16 days was evaluated. 1. P uptake by the chrysanthemum plants was nearly proportionate to P concentration in the c...

Flower-like AgCl microstructures with enhanced visible light-driven photocatalysis are synthesized by a facile one-pot hydrothermal process for the first time. The evolution process of AgCl from dendritic structures to flower-like octagonal microstructures is investigated quantitatively. Furthermore, the flower-like AgCl microstructures exhibit enhanced ability of visible light-assisted photoca...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

abstract the irrigation water quality is not suitable for crop production in most regions of iran. it is estimated that almost six bcm/year of saline water enter to the rivers, in iran. the saline water can potentially use for growing of tolerant crops with a specific management on the agriculture practice. one of the management methods is the conjunction use of fresh and saline water. in this ...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...

in a field experiment, during three successive years of 2007, 2008 and 2009, the effects of planting pattern and high corm density on agronomic performance of saffron was investigated at the research station of ferdowsi university of mashhad. a complete randomized block design in a factorial arrangement of three replications being employed. treatments consisted of three corm rates of planting (...
