A study was conducted at the University of Nebraska Field Laboratory, Mead in 1969 to investigate agronomic responses of soybean (Glycine max. L. Merrill) to TIBA and 2, 4-D foliarly applied singly and in combinations.

Fifteen treatment consisting of 35 g/ha and 70 g/ha rates of TIBA and 0.25 g/ha, 1.25 g/ha, 2.5 g/ha, 35 g/ha rates of 2, 4-D and control were applied in a randomized complete bloc design.

Plants treated with TIBA alone and in conditions with 2, 4-D were shorter, matured earlier, lodged less and had pods setting lower than untreated plants. 2, 4-D treatments however did not affect plant height, height of lowest pod, and maturity. All the treatments increased branching of plants and decreased seed weight.
