In Singapore, where less than 1% of land is allocated for food farms, the nation imports over 90% of its food requirements. In response, Singapore aims to locally produce 30% of its nutritional needs by 2030 to bolster food security. Key to achieving this is the use of technology to enable farms to optimize output efficiently.
A newly published review explores the adaptation of aeroponic systems for cultivating various leafy vegetables in tropical climates, focusing on root-zone temperature manipulation and heat priming to conserve energy. The document highlights the dual benefits of indoor and greenhouse cultivation, which not only improve productivity but also enhance the nutritional value of crops.
Moreover, the review delves into achieving higher yields and nutritional quality through deficit irrigation in a cost-effective manner. The popularity of vertical farming is also addressed, showcasing its ability to increase land utilization. A commercially viable, LED-integrated aeroponic system is presented as a solution for vertically growing vegetables. Additionally, the paper examines the effects of LED spectral quality, quantity, and duration on vegetable production, emphasizing the importance of these factors in optimizing crop growth.
