Abstract
In outdoor pot trials near Nacogdoches, Texas in 1988, pearl millet was given 0, 1.15, 3.38 or 7.77 g P/m² with or without water stress conditions. Whole plant DM at final harvest, 84 d after emergence (DAE) increased from about 145 g/pot without P to 626 g with 7.77 g P without water stress and from 64 g without P to 220 g with 7.77 g P with water stress. There was a highly significant water treatment × P rate interaction in terms of plant DM at harvests 28-84 DAE. Grain DM at 84 DAE increased with increasing P rate but was negligible without P without water stress and with <3.38 g P under water stress conditions. Maximum whole plant production rates occurred between 42 and 58 DAE without water stress, increased from 5.0 g/d without P to 18.5 g with 7.77 g P, and between 28 and 42 DAE in water stressed plants, increasing from 1.3 g without P to 8.5 g with 7.77 g P. Growth rates of panicles and grain increased with increasing P rate and were greater without than with water stress. There were no clear effects of P rate or water stress on NAR or RGR.
