Pengaruh Jumlah Nozzle Pada Instalasi Aeroponik Vertikal terhadap Respon Pertumbuhan Tanaman Selada Romaine (Lactuva sativa var. Longifolia)

Abstract

Nozzle is agricultural equipment sed to break the liqid and make it fine particles resembling mist. Romaine lettuce (Lactuva sativa var. longifolia) is one of the varieties lettce that has the characteristics of forming a head like lettuce, its groth is higher, the leaves are more erect, anf the crop is large and dense. This study aims to determine the effect of differences in the number of nozzles on plant growth responses. The parameters studied were water discharge, plant height, leaf length, root length, wet weight, plant dry weight, and plant diameter. The results showed that the difference in the number of nozzle had an effect on plant height, root length and plant diameter.
