The current Investigation was conducted to assess the effect of three sowing dates (October, November and December) and the foliar application of Fe, Mn and Zn and their combinations on growth, flowering and carthamin content of safflower plant. All plant characteristics were significantly affected by sowing dates and micronutrients application. Better growth and higher carthamin content appeared to be more closely related to earliness of planting as October favored the best results. As sowing date was delayed, significant reductions in all plant growth characteristics were noticed. Fe and/or Mn positively affected plant height, branch number/plant, head number/plant and plant fresh weight. However, plant dry weight and petals dry weight/plant had the highest values in Zn-treated plants. Petals content of carthamin recorded the highest values when plants were sprayed with Fe alone or in combination with both Zn and Mn during either October or November. Accordingly, it is recommended that safflower plant is preferably planted in October; otherwise any delay in sowing date will severely affect its yield and quality. To ensure better growth and higher yield of carthamin, a foliar application of Fe at 300 ppm or its combination with Mn at 200 ppm and Zn at 150 ppm is recommended.

Corn is one of the main cereal crops in the world. Most of agricultural expansion in the world is confined in the desert where shortage of water and unfavorable soil properties and nutrients deficiencies are the most constrains facing any agricultural project proposed for such areas. These soils need a high efficient irrigation and fertilization system for maximizing the production and sustain both the environment and resources available. Using split randomized complete plot design with four replications a field experiment was conducted out to study the effect of soil moisture and form of P fertilizer on uptake of P by corn plant as well as the yield production of corn under the effect of these treatments. Keeping the soil moisture at 125% of field capacity significantly (p0.05) increased the total uptake of P in the 60-days old corn plants from 9.38 to 10.16 kg P fed . 1 Forms of P fertilizers had a little effect on P concentrations in corn plants.Increasing the amount of irrigation water increased the grain and straw yield of corn

Halophytes are plants that can tolerate and grow on soils having high salt concentration. These plants have been suggested to be more effective in phytoextraction of heavy metals from the contaminated soils compared to the conventional crop plants .This give an offer for a greater potential of phytoremediation research on decontamination of heavy metal polluted soils. Screen house experiment was conducted out to study the accumulation of heavy metals by three halophyte species: Atriplex amnicola, A. undulate and A. lentiformis .Significant differences were found between the studied species in heavy metals concentration (Cd, Pb and Ni) and transport from the roots to the shoots. Atriplex lentiformis could be more effective in the phytextraction of Cd from the contaminated soils.
