Irrigation water plus rainfall have been monitored, by means of rain gauges with an oil overlay to prevent evaporation, from Could via September in 2001, 2002, and 2003. The amount of water applied to each and every WL is presented as mm per week (Table 1). Reference evapotranspiration (ETo) values for these time periods were obtained in the Utah Climate Center, working with the Hargreaves equation, at a climate monitoring station around 3.two km from the Evans investigation farm (USC00425194) and when compared with water applied at each and every WL (Table 1). The resulting typical % ET replacement more than the 3 growing seasons was 105, 84, 59, 40, and 18 , for WL 1, two, three, four, and 5, respectively (Table 1), assuming one hundred irrigation efficiency. Fertilizer applications of 56 kg N ha-1 of ammonium nitrate were produced before the very first harvest and immediately after Harvests 2 and four every single year.Table 1.

The very first harvest was performed when development in WLs 1 and 2 had been visually estimated to become between the vegetative and elongation stage [26]. At all subsequent harvests, plots had been within the vegetative stage and occurred when plant regrowth reached 25 to 30 cm in height. All plots were harvested around the same day on each of 5 dates in 2001 and 2003 (24 May, 20 June, 18 July, 14 August, and two October in 2001, and 19 May possibly, 17 June, 21 July, 20 August, and 30 September in 2003). In 2002, a late-season frost stopped plant development in early June and also the plots had been harvested at that time resulting in six harvests (13 May possibly, four June, 28 June, 23 July, three September, and 10 October). For purposes of this manuscript the four June and 28 June 2002 harvests had been summed and regarded as Harvest two. Forage samples utilized to estimate % dry matter have been dried at 60 C in a forced-air oven to continual weight, plus the forage mass (Mg ha-1 ) of each plot was determined. 2.two. Statistical and Genetic Analysis Forage mass was analyzed inside WL, each including `harvests’ within the model or.
