effect of irrigation with wastewater and foliar application of complete fertilizer on forage yield and yield components of foxtail millet (setaria italica)

in order to study effect of irrigation with wastewater and foliar application of complete fertilizer on forage yield and seed yield and yield components of foxtail millet (setaria italica). a split plot experiment based on randomized complete block design with three replications was conducted at the agriculture institute of zabol university in year 2009. treatments included three levels of irrigation: irrigation with well water at all stages of grows (control), irrigation with wastewater and tap water alternately, irrigation with wastewater for all growing stages, as the main plot and sprayed with three levels of complete fertilizer (natba-lib): non spraying (control), sprayed with 600 and 1200 gram of complete fertilizer in each hectare, as were the subplots. results showed that irrigation with wastewater and complete fertilizer sprayed had significant effect on all traits except leaf to stem ratio. furthermore, among the irrigation treatments, irrigation with wastewater in total growing period, and wastewater and tap water alternately lead to significant increase in grain yield, forage yield and yield components. among the sprayed treatments, sprayed with 1200 gram of complete fertilizer had highest forage yield and grain.
