Using a novel randomized phase-out research method, we \nprovide experimental tests of the effects of program phase-out in the context of a largescale \nagricultural input subsidy and extension program operated by the NGO BRAC to \nincrease the use of improved seed varieties and basic farming practices among women \nsmallholders in Uganda. We find that while supply of improved seeds through local, BRAC \ntrained women declined, demand does not diminish, and farmers shift purchases from \nBRAC to market sources, indicating a persistent learning effect. We also find no evidence \nof declines in the practice of improved and less costly cultivation techniques taught by the \nprogram. These results have implications for both efficient program design and for models \nof technology adoption.
