The effects of applications of plant growth regulators and additional fertilizer on dry matter production of green panic (Panicum maximum Jacq. var. trichoglume Eyles), cv. Petrie were investigated for the first growth during 26 days after application and the aftermath without any applications during 42 days. The application of GA3 (90 mL/m2 of 200 ppm solution) and of PP-333 (90 mL/m2 of 860 ppm solution) suppressed dry matter production of green panic by inhibiting tiller production in the former and tiller elongation in the latter. Dry matter production under aftermath in GA3-plot was enhanced due to the growth of many tillers from the tiller buds, the growth of which had been suppressed by GA3 application. The inhibition of tiller elongation by PP-333 application increased the number of tillers with apex in stubble at cutting. These tillers produced many daughter tillers after cutting, contributing to the enhancement of dry matter production under aftermath. The application of additional fertilizer (10 g/m2 each of N, P2O5 and K2O) enhanced dry matter production under direct effect by stimulating tiller growth. However, the stubble had no advantageous characteristics for tiller production, so dry matter production was not enhanced under aftermath. The above results gained in green panic may be applicable to the control of seasonal changes in dry matter production of forage grasses.
