In order to evaluate the effect of irrigation and use of organic fertilizers and agronomic and physiological traits millet varieties (split-split plot) in a randomized complete block design with three replications Damghan in 2012-2013. Millet cultivars (Bastan and Pishahang) were the main factor, no irrigation stress (stages of BBCH55 and BBCH65 and control) were the sub factor and fertilizer level (no fertilizer, farmyard manure 100% and compost 100%) was the sub-sub factor. The results showed that the greatest amount of soluble sugars was 13.62% under the three factor effect of cultivar, no irrigation and fertilizing in Pishahang cultivars with control fertilizing rate and no irrigation at BBCH55 stage. The highest amount of fiber under the three factor effect was 55.44% in Bastan cultivar with farmyard manure 100% and control. The highest protein percentage was in the interaction between cultivar and no irrigation in Pishahang cultivar and no irrigation at BBCH65 stage. Maximum percentage of ash was 8.1648% in Bastan cultivar. The highest dry matter production was 54.14% in the interaction between cultivar and no irrigation in Pishahang cultivar and no irrigation at control stage. According to the results, we can say that both Bastan and Pishahang cultivars have good forage yield and considering their short growing period, they can be used as second crops for forage production. Moreover, severe stress reduces the forage yield and production efficiency. In addition, adding farmyard manure and compost significantly increases the yield in these forage plants.

In order to determine the effects of nitroxin fertilizer under limited irrigation a split-plot factorial experiment arranged in randomized complete block design was conducted at Damghan in cropping year 2012-2013. The treatments included three irrigation levels {control (full irrigation), irrigation cessation at start of flowering and completion of flowering} in main plots, and application of Nitroxin fertilizer, with () and without (-). and the three forage millet cultivars (Bastan, Pishahang, and Isfahan( in sub plots. Results indicated that the highest forage protein contents belonged to the cultivars Isfahan (24.31%) and Pishahang (24.19%) cultivars, the largest ash content (8.22%) to Bastan, and the highest chlorophyll a contents (1.34 mg/g fresh weight) (Party leaf) to the treatment of interactions between three factors. Moreover, the highest chlorophyll b contents (1.10 mg/g fresh weight) was observed in control treatment (full irrigation) of the Bastan cultivar without fertilizer application, and the highest total chlorophyll contents (2,44 mg/g fresh weight) in control treatment of cultivar Bastan without fertilizer application, and also the highest wet forage (88.43 t/h) is obtained in control treatment and bastan cultivar. The millet plant tolerated high levels of irrigation cessation, and Nitroxin was effective in increasing yield. Considering the very rapid growth of millet, and because of the great demand as a forage, we recommend Bastan cultivar plantation in the damghan region.
