| Abstract/Contents: | "Tifgreen bermudagrass grown under different nutrient treatments in a greenhouse and artificially frozen in a growth chamber showed that nutrient level has some effect on winter hardiness. The nutrient treatment levels did not seem to vary the temperature range required for killing the grass over the range of 1 to 3 C. Within this range, the P/K ratio in the tissue appeared to influence cold hardiness. A high P/K ratio increased winterkill whereas low ratios showed little damage. Tissue N levels showed little effect on winterkill but seemed to influence uptake of P and K. N, P, and K were applied at the rate of 1.47 kg/100m2 per month through December 1967 to Tifgreen bermudagrass under field conditions at College Station, Texas. With a low temperature of -8 C there was no winterkill of grass from any treatment. Plots receiving late applications of N remained green longer in the fall and were the first to recover in the spring. Under greenhouse conditions as well as in the field the tissue content of P and K tended to increase as the N level increased. Chemical analysis of grass samples collected from the various treatments showed a direct relationship between tissue content of N-K and N-P." |
