註釋In Ecuador, the main fertilizer for rice cultivation, Urea, may be lost as much as 60% when it is applied with Broadcast technique. Urea Deep Placement (UDP), originally utilized in Asia, has been shown to enable rice farmers to reduce such a loss. This thesis is an ex-ante analysis of the potential for UDP adoption in two major rice producing cantons in the Ecuadorian Coast, Daule and Santa Lucia. A survey was implemented to collect information of rice farmers across 35 villages. A descriptive analysis explored variables that may affect adoption decision. For instance, some farmers obtained negative net incomes, implying the need of more efficient innovations like UDP. In the Double-bounded exploratory analysis was detected that 93.25% of the sample farmers were willing to pay extra for Urea briquette sacks with the introduction economic benefits/costs and with the inclusion of economic and environmental impacts. In analyzing the Intensity of Adoption (IA), potential adopters would dedicate a 49.7% of their total land for UDP production, on average. Finally, the two-limit Tobit model of the technology adoption decision (in terms of the IA) suggests that the smaller a farmer, the higher his probability of UDP adoption. However, the subsidy of Urea fertilizer may be an obstacle for UDP acceptance. Social network was also significant in the model; potential adopters' behaviors may influence a farmer's adoption decision. Other significant variables were small kids in a household, market access, rented land, credit solicitation, agricultural insurance, risk aversion, UDP knowledge and on-farm hours.
