Abstract
ABSTRACT Then a field experiment in two consecutive seasons on a farm in the Division lead to study the effectiveness of the added phosphorus spraying on the leaves and compare them added to the ground on the vegetative growth of wheat plants under conditions of Algeria, where you use three factors for phosphorus P0 - Ps - Pr (without adding phosphorus - affixed to the ground - added spray), respectively. and massage at 50 parts / million P2O5 on the image of super phosphate, and then added in two 3 / 2 amount by the Agriculture mixing with the soil and 3 / 1 the remainder after 15 days of agriculture, was also used phosphorus spraying on the leaves concentration of 1% of the sodium phosphate mono NaHPO4 three periods after 30 - 35 - 40 days of agriculture, and selected two types of soil differ in physical and chemical characteristics, results showed the following: Increased the dry weight of shoot significantly by adding phosphorus to any of the methods for the treatment of comparison, regardless of the type of soil The addition of phosphorus in any of the methods to increase the number of leaves and the back in both two soil in the two phases of growth. The addition of phosphorus to the ground to the significant increase in total dry weight of roots and surpassed the values of dry weight of both shoots and roots in the soil of the first region than those in the soil of Talha. - The mutual influence between the two variables is statistically significantIncreased the total content of phosphorus in shoot dry any of the methods although the added Ground surpassed Added spraying on the leaves, but the same trend was observed for the dry weight of roots.
