Abstract

This paper measures the impact of a micronutrient training among women farmers with young children on the demand for zinc-enhanced varieties. We conducted a randomized control trial by providing micronutrient training in randomly selected villages in May–June 2017. These farmers were also given information on the biofortification of rice with zinc. One week after the training, we conducted a phone-based bidding for high-zinc rice seeds among trainees and their counterparts in control villages. More than 70% of the treated female farmers participated in the bidding for high-zinc rice seed, but only 23% of the women in the control group participated in the bidding. Female farmers who self-reported that they had input into most or all decisions on the use of income generated from rice bid a higher price than other female farmers. The results suggest the effectiveness of the micronutrient training, at least in a short period immediately after the training.
