Abstract: Field studies, over a two-year period, were conducted to determine the effect of TIBA (triiodobenzoic acid) on the balance between vegetative and reproductive development of soybeans. The soybean varieties Clark (or Clark 63) and Wayne were grown under nonirrigated and irrigated conditions in 20-inch rows.
Four rates of TIBA were applied at three stages of growth to determine the rate of TIBA and the stage of plant growth at which it should be applied to obtain maximum yields. An additional study was conducted with three rates of nitrogen fertilizer applied to obtain maximum yields. An additional study was conducted with three rates of nitrogen fertilizer applied by three methods of application to determine if nitrogen could further increase grain yields above the effect of TIBA.
