University trials, large strip trials and commercial plantings have clearly demonstrated the high yield potential of the PhytoGen PHY 400 series which includes PHY 440 W, PHY 470 WR, PHY480 WR, PHY 475 WRF and PHY 485 WRF. To address management questions often asked about new varieties by cotton advisors and growers, 7 trials were initiated with Extension Cotton Specialists to determine the effect of 1X and ½X seeding rates as well as four mepiquat chloride (MC) application scenarios on the yield, growth and lint quality of this series (Tables 1 and 2). All experiments were conducted using the same factorial protocol with either PHY 475 WRF (6 trials) or PHY 485 WRF (MO trial). The "as needed" MC applications were applied as determined by the investigator based on plant development throughout the season. In most trials, data was collected to document first fruiting branch, node above white flower (NAWF) (as the crop neared physiological cutout), plant height (at mid to late season), total nodes, lint yield and quality (based on HVI analysis). Locations of the trials as well as the data collected are provided in Table 3. [ABSTRACT FROM AUTHOR] |
