Significant improvements in average plant heights, plant vigour ratings, greenness of foliage and yields were recorded at the lx and similarly at the 1/2x irrigation rates however the additional water in the 2x treatment was outstanding indicating that greater quantities of water was necessary in this very dry year (Fig. 20 - rainfall comparisons between 2005,2004 and 2003) for excellent seed corn inbred production. Inigation improved the growth characteristics to a greater extent in the later maturing seed corn inbred. Tables 8 a & b.
