- ... Models provide a quantitative means to evaluate yield response of forage grasses to applied N and water availability. The objective of this analysis was to estimate model parameters (A, b, c) for bermu. dagrasses and bunchgrasses grown at the same location and during the same time period. The logistic equation was used to relate annual dry matter production to applied N for three bermudagrasses [C ...

- ... Early spring applications of herbicides were evaluated for weed control and phytotoxicity to kleingrass (Panicum coloratum L.) during establishment. In 1986, areas treated with MSMA (monosodium salt of methylarsonic acid) at 2.2 and 4.5 kg ha⁻¹ or chlorsulfuron [ 2-chloro-N-[ [(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] benzenesulfonamide] at 0.018 and 0.035 kg ha⁻¹ reduced weed yield ...
