Abstract Potato has been recognized as a crop of importance in developing countries for ensuring human nutrition and food security. The dwindling natural resources, low fertility of soils, the incidence of pests and diseases, climate change and lack of strategic planning pose major constraints for potato production in these countries. Crop models are efficient tools for assisting research and development efforts towards achieving maximum production potential in these areas as it predicts the phenology and yield of crop taking into consideration the factors affecting growth and development. A wellvalidated model can be used for quantification of adaptation domains, optimization and efficient utilization of resources, forecasting of pest and diseases, mitigating climate changes, yield gap analysis, a pre-harvest judgment of production and accordingly market surveillance and formulation of monitory policies. The multifaceted application of simulation models presents futuristic opportunities for developing decision supporting systems and agro-advisory services for scheduling best management practices for attaining sustained potato production. This review summarizes comprehensive information on the crop models being used along with their applications in the different aspects of potato production system towards a precision as well as smart agriculture.

Potato Research
Introduction Potato, the third most important food crop in the world after rice and wheat, has become the main source of food and income in developing countries (Raymundo et al. 2017). It has a potential role in improving human health due to the presence of several phytonutrients, vitamins, minerals, proteins, carbohydrates and dietary fibres (Mishra et al. 2020), and therefore can be considered an important food crop for ensuring nutritional security of world populations. The recent trends in potato production and consumption revealed that its consumption has been declining in Europe and North America whereas it has been constantly increasing within the developing world, where it has a crucial role in food security (FAOSTAT 2018; Wijesinha-Bettoni and Mouillé 2019). Additionally, the advantages of being able to produce more dry matter in a short duration and its feasibility to be included in different cropping systems mean potato cultivation is gaining momentum in food grain-based cropping systems. The factors such as
