The study followed the influence of irrigation rate on early and total yields of tomatoes (Lycopersicon esculentum Mill.) grown in unconventional system, on different types of substrate. Purpose of the study was to recommend variant with lowest cost for irrigation rate to make an early and total production more efficient. The study was carried out in the greenhouse, using the biological material hybrid Cyndel grown on three types of substrate (perlite, mineral wool, cocopeat). We applied three watering rates and have been carried out on biometrical measurements dynamic plant growth, inflorescence formation. Has been registered early and total production for each variant of substrate and watering rate the highest yields were obtained at V3 (119.43 t/ha) at which was apply watering rate b (6560 m 3 /ha). The results showed differences between variants, both with regard to plant height, and the total production in comparison with the rate of irrigation. When using mineral wool and cocopeat substrates were recorded plant height compared with variants that have used perlite.
Hydroponic systems are highly appreciated today, due to their potential to protect the environment and ensure a high level of food safety. In general, aromatic plants play a very important role in the food, pharmacy, cosmetics, perfumery and aromatherapy industries, all these products being highly appreciated by consumers. Due to their importance, different hydroponic systems are put in place to grow at different levels, these aromatic plants. In the present study, is analyzed the influence of three different hydroponic systems (two vertical and one horizontal) on minerals content and nutritional quality of two varieties of Occimum basilicum and one Mentha piperita variety. In this study are presented dry matter content, ash, micro and macro elements and contaminants content of leaves are presented. The results showed that the vertical system without foil had the best results, followed by the vertical system with foil comparative to the horizontal system that had the lowest content in nutritious principles. The vertical eco-sustainable systems proved to be a promising innovation for growing aromatic plants at the household level and a promising start for the intensive growing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
