Irrigation generally increased Bermuda-grass hay yields both annually and across cutting intervals.Irrigation linearly increased Bermuda-grass hay yields in five of ten four-week harvests and in two of six eight-week harvests.In 2008,the overall yearly four-week harvest hay yields were significantly linearly correlated with the irrigation treatments.Likewise,the individual four-week harvests were also positively linearly correlated with irrigation treatment for all harvest except the August 2008 harvest.The August harvest was negatively correlated to irrigation treatment.During the growth period for this harvest,no irrigation was applied because of plentiful rainfall.Additionally,the plant nitrogen removed in the hay had a similar negative trend,possibly indicating that 165 mm of rainfall during that harvest interval may have leached available Nitrogen below the root zone.

灌溉一般能提高每年和跨刈割间隔期的百慕达草干草的产量.灌溉在十次四周收割中的五次,以及六次八周收割中的两次中使百慕大草干草产量有线性增加.2008年,整年的的四个星期的收割干草产量都与灌水处理呈现明显的线性相关.同样,所有收割中,各次四个星期的收割也与灌溉处理呈正线性相关关系,只有2008年8月那次收割例外.八月的那次收割与灌溉处理呈负相关关系.在这次收割的生长期间,没有进行灌水,因为雨量充沛.此外,在甘草中植物氮素在干草中的去除也有类似的负面趋势,这可能表明在该收割时间间隔内165毫米的降雨可能已经浸出了根部区以下可获得的氮.
