This study was conducted to determine whether increasing urea fertilization ratios at the initial flowering stage or fertilization once at the budding or the initial flowering stage could improve seed cotton yield, plant 15N recovery, and decrease fertilizerN loss (FNL).
Actually, we do have some 3-dissection formulas to find how [[summation].sup.[infinity].sub.n=0] [c.sub.15] (15n + 9) [q.sup.n] and [[summation].sup.[infinity].sub.n=0] [c.sub.15] (15n + 14) [q.sup.n] modulo-3 look like.
