Abstract
A field trial was conducted during the two successive seasonsof 2007 and 2008 in the Experimental Farm at Demo (a newlyreclaimed soil), Faculty of Agriculture, Fayoum University toinvestigate the influence of phosphate fertilizer at the rates of 0,100,200 and 300 kg/fed as (calcium superphosphate, 15.5 % P2O5 )before planting during soil preparation, and /or some micronutrientscombined fertilizer of Pholaz D, ( 2.8 % Fe ,2.8% Zn and 9.2 % Mn )as foliar spray with three concentration 0, 0.1 and 0.3 % ,alone or incombination with each other on improving growth, seed or oil yields,and some chemical constituents of sunflower plants (Helianthusannuus L.) under a newly reclaimed soil. The obtained data showedsignificant positive influences of all phosphate and micronutrientstreatment used in this study were observed on growth, yields of seedsor their oil contents and some chemical constituents in both testedseasons. In comparison with the control, treated plants withphosphate and micronutrients at all studied rates significantlyincreased vegetative growth traits (i.e., plant height, number ofleaves/plant, total leaf area/plant and dry weight of leaves/plant),seed yield /fed and its components (i.e. head diameter, head dryweight, seeds weight /plant, 100 seed weight ), in addition to somenutrients( i.e., N, P, K, Fe, Mn, Zn) and chemical constituents (i.e.,total carbohydrates, crude protein and seed oils). The maximumincreases in the studied plant parameters were resulted from usingphosphate fertilizer at the rate of 300 kg/fed and combined fertilizerof micronutrients at the rate of 0.3% alone or together.In view of these results, it could be concluded that treatedsunflower plants with phosphate at the rate of 300 kg/fed and theused combined fertilizer of micronutrients at the rate of 0.3% aloneor together producing on economic yield for each of seed and its oilcontent.
