Growth features and yields of radish accessions in vertical hydroponic system in the City of Omsk

Abstract

Among green vegetable crops, the radish (Raphanus sativus) holds a special place; it is grown everywhere, both on a commercial scale and on personal subsidiary plots. The issues of obtaining Raphanus sativus products in our region in protected ground at any time of the year are relevant. One way to produce radishes year-round is hydroponics. Vertical hydroponic systems are used to increase yields even in small spaces. The experiments to study of radish accessions were carried out in 2022 and 2023 at the educational, scientific and production laboratory “Sadovodstvo” of the Omsk State Agricultural University. Nine accessions were chosen for the research: Beliy zefir, Krasa Altaya, Zhara, Rozovo-krasniy s belym konchikom, Champion, Espresso, Celesta F1, Cherriet F1, and 18 dney. During the research, phenological observations and biometric measurements of radish accessions were carried out under the conditions of a vertical hydroponic system, and the most productive ones for cultivation in the Omsk Region were identified. It was found that the radish accessions grown in the vertical hydroponic system differed slightly regarding the phenological indices. Good indices in terms of root weight were found in the varieties 18 dney, Zhara, Champion, Espresso, Krasa Altaya, Beliy zefir, and Rozovo-krasniy s belym konchikom.  The yields of radish accessions grown hydroponically ranges from 1.4 kg m² in the standard variety Rozovo-krasniy s belym konchikom to 3 kg m² in the Champion and Celesta accessions. All accessions produced a higher yield than the standard variety did. High yields were also observed in the Zhara, Champion and Cherriet accessions - 2.6 kg m².
