The significance of building sustainable farms has been highlighted in the search for food security. The traditional farming methods used in Nigeria result in low agricultural yields. Utilizing modern technologies, such as nanotechnology, is crucial right now to address the growing need for food crops. These objectives gave birth to nanotechnology as a frontier for the twenty-first century. Nanoparticles may be helpful in the treatment and monitoring of diseases affecting agricultural crops because they specifically target microorganisms. Crop diseases are fought by nanoparticles, including carbon nanoparticles, silver nanoparticles, and silica nanoparticles. An edible coating containing encoded nanoparticles is one such technique for preserving and storing food. Agricultural fields can be equipped with nano-sensors to track soil fertility and other agro-climatic factors. Nanomaterials are utilized to remediate deficient soils and offer a clever, unique, environmentally responsible, and long-lasting solution. Green nanotechnology may be used to improve the hygiene of food items, leading to a better lifestyle for the general public. An effective substitute for better recycling of agricultural waste might be nanotechnology. These are the ideal raw materials for biochar, renewable energy, and nano-silica. Agriculture also uses barcode technology and nano-based identifying markers. The intentional use of nanomaterials in agricultural endeavours may have unanticipated health effects. Future agricultural issues like food security have a lot of potentials to be solved with the help of nanotechnology applications, particularly in developing countries.

Drought as the most important abiotic stress has deleterious effects on plants. Developing drought tolerant varieties can help produce plants in a sustainable way. This study was conducted to identify drought tolerant and drought sensitive thyme species including Thymus vulgaris, T. vulgaris (origin: Spain), T. carmanicus, T. daenensis and T. kotschyanus and to study the mechanism used by them to cope with drought stress. For this purpose, relative water content, water use efficiency, soil water depilation rate, root:shoot ratio, drought resistance index and a new criterion "FC ceased growth" were used. T. carmanicus and T. daenensis had the lowest and the highest reduction on relative water content, respectively. In terms of water use efficiency and soil water depletion curve, the highest and the lowest values were detected for T. daenensis and T. carmanicus, respectively. The most and the least root:shoot ratios were recorded for T. daenensis and T. vulgaris (origin: Spain), respectively. Analyses by drought resistance index and PCA revealed that T. carmanicus is drought susceptible, T. kotschyanus and T. vulgaris are semi-drought susceptible, and T. daenensis and T. vulgaris (origin: Spain) are semi-drought tolerant species. FC ceased growth analysis showed that T. carmanicus stopped its growth at higher FC, while T. kotschyanus stopped it at lower FC. Therefore, based on this criterion and considering the sustainability of growth under drought condition, T. carmanicus and T. kotschyanus are the least and the most drought tolerant Thymus species.
