With the aim of reducing the cost and time needed to treat yam tubers with gibberellic acid (GA(3)), this study compared several new methods of application with the established dipping procedure (150 mg kg(−1) for 1 h). Both GA(3)-containing soil paste (25 mg kg(−1)) and gelatinized starch (860 mg k...
