regimens using various rates and application times of N and Fe ( Table 1 ). Mowing was performed every 7 d throughout the growing season at actual set heights using a rotary-type mower, and clippings were returned. N fertilization was provided by a granular
orchard area. Worley (1997) observed that pecan yield, quality, and leaf N could be maintained with dry fertilizer applications when the full N rate was concentrated in a limited area, yet no studies have attempted to refine this practice by simply

applications on cucurbit rootstock tissues have not been characterized. The first objective of this experiment was to determine the optimal application rate of commercially available fatty alcohol compounds that would control rootstock regrowth without damaging
