Zimbabwe has slowly adopted Internet of Things for smart agriculture as a way of improving on food security in the country, though there is hesitancy by most farmers citing trust issues as monitoring of crops, animals and farm equipment’s would be done online through connecting several devices and accessing data. Farmers are facing difficulties in trusting that the said technology has the ability to perform as expected in a specific situation or to complete a required task, i.e. if the technology will work consistently and reliably in monitoring the environment, nutrients, temperatures and equipment status. The integrity of the collected data as it will be used for decision making. There is a growing need to determine how trust in the technology influence the adoption of IoT for smart agriculture in Zimbabwe. The mixed methodology was used to gather data from 50 A2 model farmers randomly sampled in Zimbabwe. The findings revealed that McKnight etal. trust in technology model can be used to influence the adoption of IoT through trusting that the technology will be reliable and will operate as expected.Additional constructs such as security and distrust of technology can be used as reference for future research. KEYWORDS Internet of Things, Adoption, Smart Agriculture, Trust, Trust in Technology 1. INTRODUCTION The adoption of Internet of Things for Smart Agriculture in Zimbabwe will see an increase in food production resulting in improved food security and minimizing food imports such as maize, wheat and soya beans as revealed through research by[1]. The introduction of technology in agriculture has boosted food production in some of the developed countries especially in the United States of America (USA) and other developing countries. Although the Zimbabwean farmers are gradually adopting smart agriculture because of its perceived usefulness and perceived ease of use which are the key determinants of IoT use in agriculture. Farmers are facing challenges in trusting IoT farming systems as the technology has failed to perform as expected in a specific situation or to complete a required task. Also farmers need to trust the integrity of the collected data as it will be used for decision making. Five agro-ecological regions in Zimbabwe are classified as natural regions. These regions are categorized according to the amount of rainfall, soil quality, vegetation, climatic conditions among other factors. Zimbabwe’s rainfall pattern ranges from 550 to 900 millimeters across the
