in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

Introduction Yellow mustard (Sinapis alba L.) is a new multipurpose rotation oilseed crop for Willamette Valley agriculturalists, especially non-irrigated operations. Yellow mustard can also be used to produce condiment mustard, as a green manure crop, and as a biopesticide. Although yellow mustard seed production is relatively new to the Willamette Valley, Oregon’s north-central counties have ...

to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...

In order to study on effect of plant density and nitrogen on yield and yield components of Visia faba (faba bean), the experimental design was implemented by randomized complete block with three replications at 2010- 2011 in Lahijan. The experimental factors were three plant density (25×25 cm, 35×35 cm and 45×45 cm) and four nitrogen fertilizer (0, 20, 40, 60 kg ha-1). In this experiment, featu...

A field experiment and a laboratory experiment were conducted in 2011 to determine the effect of intensity of defoliation on yield of maize (Zea mays). The field experiment included seven defoliation intensities (0, 2, 4, 6, 8, 10 and whole leaves per plant) from top to bottom leaves. Seeds of the field experiment were used for the laboratory experiment. In the laboratory experiment, germinatio...
