Abstract: Abstract In this paper, economic feasibility of two vegetable crops (i.e., cucumber and tomato) cultivated in a naturally ventilated greenhouse, and the net present worth, cost-benefit ratio, payback period, and internal rate of return for these crops on year-round cultivation are presented. The cost-benefit ratio demonstrated that growing cucumbers and tomatoes can be economically viable in this climatic region. The present experimental study was conducted in the composite climatic condition of Udaipur (24°35′N, 73°42′E), India. The study area is defined as arid and semi-arid region of Indian climatic conditions. Droughts are a recurring phenomenon in arid and semi-arid regions creating a situation that affects not only agricultural productivity but also people’s health. In particular, the western part of the state is a desert, and its socioeconomic status influences nutrient purchasing power. A poor diet can lead to a vitamin and mineral deficiency. The state of Rajasthan has good agricultural potential; interventions using protected cultivation practices can increase the production and productivity of vegetable crops. However, the current adoption rate of such practices in the state remains very slow, even after a promotional scheme offered by the state government. The government and policymakers should consider offering demonstrations of practices at a larger level. Farmers of the state are marginal and economically poor, requiring more financial assistance. Low cost technologies would be suitable for these farmers.
