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...

The present study aims to assess the effect of Thiobacillus and sulfur on morphological and biochemical properties of medicinal pumpkinproperties under deficit irrigation based on a split-plot design. For this purpose, water stress was applied as a main factor in three levels (control, no irrigation in flowering stage, no irrigation in fruiting), and Thiobacillus and sulfur fertilizers as sub-p...

Flowering and vegetative growth were assessed in 19 half-sib families of Alnus rubra Bong. planted in a replicated field trial near Olympia, Washington, USA. The trial consisted of three square spacings (0.5, 1.0 and 2.0 m), two irrigation regimes (low and high), and two fertilization treatments (0 and 300 kg P ha(-1)). Male and female flowers were surveyed in all plots for all families at plan...

water resources are limited in most parts of the country, including isfahan,where cotton is cultivated but it’s planting time coincides with the sensitive stage of cereal grain growth. therefore, developing and adopting techniques that could maximize use of the existing resources is needed. to study the effect of basin and furrow irrigation methods on yield and some yield components of cotton  ...

concerning limitation of water resources, determination of the least water that can lead to the maximum yield is of great importance in crop production. in order to evaluate effects of deficit irrigation on grain yield and water use efficiency of some wheat )triticum aestivum) cultivars under different climatic conditions, two similar field experiments were conducted in 2004 in agricultural res...
