Hydroponic lettuce (Lactuca sativa) & spinach (Spinacia oleracea) cultivation with the effect of nannob[b]ubles (AgroNB) in the greenhouse on crop growth, yield and nutrient uptake

Abstract

In this dissertation experiment we researched the influence of Nano bubbles in green leaf lettuce and spinach using hydroponic floating disks. The experiment took place in a greenhouse and after in a shade house at Perrotis College, American Farm School. The experiment consisted of four main treatments: air pump & two air stones enriched with NB (Spinach & Lettuce); tap water, air pump & two air stones (Spinach & Lettuce); tap water enriched with NB (Spinach & Lettuce); and, tap water (Control) (Spinach & Lettuce).The data analyzed in the end were the measurements of the plant and root weight, plant and root height, SPAD, NDVI, E.C., and pH. The results showed that many significant statistical differences exist between these four treatments.
