EFFECTS OF PHOSPHATE FERTILIZER AND DROUGHT STRESS ON PHYSIOLOGICAL TRAITS IN FORAGE MILLET VARIETIES

ABSTRACT: in this research the Effects of phosphate fertilizer and drought stress on forage millet of field in 2011 experiment was conducted. This experiment was replicated three times based on a randomized complete block design in split plot was the main factor of three levels of irrigation (non-stress conditions, interrupted in 55 and 65 BBCH) is a minor factor with three levels of super phosphate Triple fertilizer before planting (without fertilizer, fertilizer 100 kgha-1 and 200 kgha-1), two varieties of forage millet (Bastan and Pishahang). Results showed that Comparison showed that most proteins in the vanguard of the 13.9 percent were observed. The highest dry matter production under irrigation in the 55 BBCH Equal to 73.44 percent, and also most carbohydrates in ancient varieties and irrigation at 55 BBCH Respectively 23.71percent. Comparison of the minimum amount of fiber in the vanguard and irrigation at 55 BBCH Respectively 21.83 and 20.11 percent respectively, the maximum amount of fiber under irrigation at 65 BBCH is. Excessive consumption of phosphorus in excess of its critical level in soil in addition to imposing additional costs on production and environmental aspects of adverse effects similar to but less severe drought stress on plant growth found.
