In 1996 a single field experiment was conducted at Paloma Ranch, west of Gila Bend in Maricopa County, Arizona. Nucoton 33B was dry planted and watered-up on 15 April. Treatments consisted of various rates and times of application of nitrogen (N) and calcium (Ca) from two sources (N-Cal and CAN -17), as well as a standard N source, UAN-32, along with a Ca check, which received no Ca. Treatments1, 2,and 3 each received a total of 280 lbs. N/acre. Treatment 4 received a total of 210 lbs. N/acre while treatment 5 received a total of 301 lbs. N/acre. Treatment 1 was a standard for reference and received only applications of UAN-32. Treatments 2 and 4 each received a total of 72 lbs. of Ca/acre. Treatment 5 is the same as treatment 2 except that it received a total of 79 lbs. Ca/acre that included a 7 lbs. Ca/acre at water up. Treatment 3 received a total of 300 lbs. Ca/acre. No significant differences were found among the various treatments in terms of plant growth, soil water content, ECe values, and sodium absorption ratios. Lint yields were significantly different (P<0.07).
