Cotton Growth and Lint Yield As Affected By Interactions Among Nitrogen Fertilization, Irrigation and Seeding Rate

With production input costs ever increasing, it is important for producers to make the most efficient use of all the inputs utilized.  This study addresses how irrigation, seeding rates, and nitrogen fertility affected cotton lint yield and fiber quality production during the 2013-14 growing seasons.  Both irrigation and nitrogen fertility impacted the amount of the lint produced, although a positive irrigation response was only seen in 2013.  Irrigated cotton was also more effective in utilizing the nitrogen fertilization than dryland cotton in 2013.  Cotton producers may be able to use this data to more efficiently utilize their seed, irrigation and nitrogen fertilizer inputs.
