Field performance of potato minitubers produced in aeroponic culture

Abstract

The aeroponic system is a viable technological alternative for potato minituber production within a potato tuber seed system. The aim of the study was to evaluate the productivity of potato minitubers grown in aeroponic culture and collected in 14 successive periods of the growing season. The minitubers of cvs. Ametyst and Tajfun were tested in an experimental field after a storage period. It was found that cv. Ametyst was characterized by higher yield and number of tubers than cv. Tajfun. Yield of cv. Ametyst averaged 42.6 t/ha, and cv. Tajfun 37.3 t/ha. The number of tubers over 3 cm of cv. Ametyst averaged 644.2 per ha, and cv. Tajfun 437.7 per ha. The yield and number of tubers was dependent on the physiological age of minitubers harvested on successive dates. Comparing the productivity of minitubers grown in aeroponics and in the soil, a significant difference was found in the number of tubers with a transversal diameter over 3 cm. There were more daughter tubers from minitubers grown in soil. They are the result of different-size minitubers used for planting, smaller ones from aeroponics and larger from soil.

Growth, yield and dormancy of aeroponically produced potato minitubers as a function of planting density and harvesting date

“…Our study is the first to our knowledge that evaluates the effect of harvesting dates in aeroponics on the dormancy period of potato minitubers. Rykaczewska (2016) observed that the yield of potato crops formed from minitubers of cv. Ametyst harvested in aeroponics responds in a quadratic form to harvesting dates.…”

“…Minitubers of cv. Ametyst harvested at different dates had different physiological ages and varying tuber yields in the field (Rykaczewska, 2016). Therefore, there may be variation in the dormancy period of minitubers harvested at different dates, which would have implications for crop management.…”

Aerofonik Sistemle Patateste Mini Yumru Üretimi

“…Bu sistem dünyada patates mini yumru üretim alanlarında, optimum gelişme şartlarının sağlanması yanında; toprak yapısının olumsuzluklarından etkilenilmemesi, suyun ekonomik kullanılması, yılın her mevsimi mini yumru üretim imkanı sunması ile popüler hale gelmeye başlamıştır. Son yıllarda uygun teknolojik ve otomasyon sistemlerinin kullanılması ile patates gibi iş gücü ve girdi kullanımı yüksek ürünlerde el emeği ve enerji kullanımında büyük ölçüde tasarruf edilebilmesi, diğer üretim sistemlerine göre ürünün veriminde ve kalitesinde artış görülebilmesi nedeniyle (Rykaczewska, 2016a) (Otazu, 2010). Makro ve mikro elementlerin tipi ve hangi konsantrasyon aralığında verilmesi gerektiği optimize edilmelidir.…”

Growing of Virus-Free Potato Seed Tubers in the Aeroponic Plant

“…Therefore, the number of seed tubers harvested from one potato plant was several times larger, which increased the net reproduction of high-value potato seed tubers (Mateus-Rodriguez et al, 2013; Basiev et al, 2019; Rykaczewska, 2016b). On average, 805 -900 mini-tubers could be picked from the area of 1 m 2 (Abdullateef et al, 2012;Rykaczewska, 2016b). Aeroponics allows researchers to develop fully automatic plant growing systems much more straightforward than substrate cultivation systems (Gabitov et al, 2018;2018b).…”

“…The basic principle of the aeroponic plant growing is atomizing the plant with a mineral-rich nutrient water solution in the closed or semi-closed environment(Martirosyan, 2014;Rykaczewska, 2016b; Wang et al, 2017).…”
