Phosphate Fertilizer and Drought Effects on Growth Components and Elements of Forage Millet Varieties

In this research the effects of triple superphosphate fertilizer and drought on millet of forage crops affected by irrigation of in 2011 an experiment was conducted. This experiment was replicated three times based on a randomized complete block design in split split plot was factor of three levels of irrigation (non-stress conditions, interrupted in 65) is factor with three levels of super phosphate Triple fertilizer before planting (nonfertilizer, fertilizer as 100 kg.ha-1, 200 kg.ha-1) and two varieties of forage millet (Bastan- Pishahang). Results showed that potassium and calcium were significantly affected by irrigation which showed the lowest K in non-stress conditions equal in 203.39 PPM and highest calcium under irrigation in 65 steps BBCH equal in 259.33 was visible. Also sodium under the effect of varieties and irrigation showed significant differences from those in the highest number of Bastan variety irrigation at 55 BBCH Equal to 4.75 and 4.58 PPM were obtained. The maximum amount of fiber under irrigation at 65 BBCH Equal to 25.78 percent. The whole elements in millet plants that do not affect irrigation and drought have been shown to have an environmental response, indicating that millet plants adapted to dry conditions and low water is. Investigation indicators expressed in growth and dry matter of millet is a fast growth rate and duration of crop growth is determined by the result due to the large stems and leaves of forage produced.
