Horticultural crops are used for a variety of purposes, including nourishment and aesthetics. Human nutrition relies heavily on these plants for carbohydrates, proteins, organic acids, vitamins, and minerals. Drought, flood, nutrient inadequacy, heat, light, metal stress, and other abiotic stresses restrict crop plant development and output. A variety of tactics are used to improve abiotic stress tolerance, including the production of genetically modified cultivars by incorporating gene constructions to improve performance under stress. Nanotechnology is a multifaceted field that could be applied in every branch of research comprising medicine, industry and agriculture. Soil and water nanoremediation, plant nanoprotection and plant nanonutrition are some of the agricultural applications. To accomplish sustainable progress in horticultural plants challenged with various environmental challenges, numerous definitive directions have been developed to secure public acceptance and convenient utilization of nanoparticles. Even with the rapid increase in nanoparticle use in several applications, there is still a dearth of information on the actual outcomes of nanoparticle interaction with plants. This review assesses the role of nanomaterials in horticultural crops under abiotic stress, with a focus on recent research. In addition, this review focuses on explaining the broad roles of several nanoparticles in enhancing abiotic stress tolerance in horticulture plants. [ABSTRACT FROM AUTHOR]

In this paper, a comparative study assessing net metering and feed-in tariffs is proposed for grid-connected photovoltaic (PV) systems in the Kuwaiti market. This study measures the impact of the two mechanisms as well as a mechanism combining both approaches in deploying solar energy systems in residential areas. The advantages and disadvantages of each approach are inspected to determine the optimal approach for Kuwaiti market conditions. A feasibility study on installing a roof-mounted PV system in a typical Kuwaiti residential building is utilized to validate the optimum solar electricity mechanism. The proposed study intends to reduce the peak load demand in Kuwait's electric grid as a solution to the shortage of electric production capacity by encouraging investors and house owners to invest in solar energy. PV*Sol premium 2018 (R10) and RETScreen software packages are utilized to perform the assessment and study analysis. [ABSTRACT FROM AUTHOR]
