Heliyon, Journal Year: 2024, Volume and Issue: 10(6), P. e28291 - e28291

Published: March 1, 2024

Plastics are becoming common environmental pollutants. Plants behave as access routes for plastics in the trophic chain since they can adsorb particles through their roots or on surfaces. In this review, various methods sample preparation and analytical plastic isolation identification from vegetables, fruits, seedlings were discussed. The effects that have them also addressed. All of studies offer convincing proof micro nano already exist fruits easily enter into a variety effects. Since most been conducted under strictly controlled conditions using standard plastics, more tests environmentally realistic required to ensure literature applicable. Also, vegetables need be tested identify number currently there that, when consumed, could harm human health.

Soilless systems have become increasingly popular as effective solutions for regions with infertile soil, low water availability, limited space, and environmental pollution. There is information on the role of soilless culture in production medicinal plants. While some research has examined growth rates yields, there not enough data how these affect nutrient uptake, physiological properties, use efficiency (WUE) This investigated alternative techniques cultivating watercress (Nasturtium officinale). The study was conducted using a completely randomized design five replications assessed impact different cultivation (hydroponic, aquaponic, soil) watercress. results showed that had significant effects morphological, content (P < 0.01). When grown hydroponics aquaponics, exhibited 58.2 54.3 % increase height, 104.7 59.2 root length, 20.1 72.9 leaves, 44.3 11.4 lateral branches, 58.5 35.3 leaf area, 46.8 81 yield, respectively, than soil-based system. system promoted higher levels chlorophyll b, while amounts carotenoids, protein, proline, relative aquaponics demonstrated highest N, P, Mg, S, Na, soil displayed Ca, Fe, Zn concentrations. amount Fe can be attributed to organic matter, which plays chelating micronutrients enhancing their accessibility plant absorption.

Abstract Greenhouse farming is essential in increasing domestic crop production countries with limited resources and a harsh climate like Qatar. Smart greenhouse development even more important to overcome these limitations achieve high levels of food security. While the main aim greenhouses offer an appropriate environment for high-yield while protecting crops from adverse conditions, smart provide precise regulation control microclimate variables by utilizing latest techniques, advanced metering communication infrastructures, management systems thus providing optimal development. However, due information technology, are undergoing big transformation. In fact, new generation has gone simple constructions sophisticated factories that drive agricultural at minimum possible cost. The objective this paper present comprehensive understanding framework actual Qatar, so as be able support transition sustainable precision agriculture. Qatar’s market dynamic sector, it expected mark double-digit growth 2025. Thus, study may effective supporting decision policy makers, professionals, end-users introducing technologies taking advantage monitoring artificial intelligence, infrastructure agriculture sector adopting greenhouses, consequently enhancing Food-Energy-Water Nexus resilience Furthermore, analysis situation Qatar provided examining its potential regarding existing drivers barriers.
