Effects of different nutrient solutions on growth and flower quality of gerbera (Gerbera jamesonii) grown in hydroponic close system

The nutrient solution is the decisive factor for the growth and development of hydroponic plants. This study was conducted to determine the effect of five nutrient solutions, namely, Hoagland, Knop, Hydro Umat F, BKFAST, and Bio-Life, on the growth and development of gerbera (Gerbera jamesonii) in the hydroponic system. The results show that Hydro Umat F is the most suitable solution for planting gerbera in terms of plant height, number of leaves, leaf size, and root volume. In addition, the flower yield of the gerbera plants nourished on Hydro Umat F is also the highest, with 8.7 flowers per plant after five months in the hydroponic system. The flowers have a diameter of 9.8 cm and natural durability of 19.67 days. Meanwhile, gerbera plants stop growing after 15 days in the Bio-Life solution and 30 days in the Knop solution.

Effects of Nutrient Composition and Lettuce Cultivar on Crop Production in Hydroponic Culture

A greenhouse research study was conducted at Eastern New Mexico University, Portales, NM, USA, in 2019 to examine the effects of different nutrient solutions on the growth and weight of two lettuce cultivars grown in a floating hydroponic system. Two lettuce cultivars, Buttercrunch and Black Seeded Simpson, were subjected to one of four different nutrient concentrations of N, K and Ca at 150, 100, and 150 ppm (N1), 210, 235, and 200 ppm (N2), 250, 300 and 250 ppm (N3), and 300, 350, and 350 ppm (N4), respectively. The Buttercrunch cultivar and N3 treatment proved significantly more productive than the other cultivar/treatment combinations. The greatest fresh weights were recorded in the N3 nutrient solution, 115.33 and 93.17 g/plant for Buttercrunch and Black Seeded Simpson, respectively. Buttercrunch had the greatest fresh weight, leaf number, and leaf and root length in all nutrient solutions. The nitrogen content of the solutions showed a significant positive relationship with chlorophyll content for both cultivars. It is expected that the development of a cheap and easy-to-use hydroponic system will help growers produce high-quality organic vegetables including lettuce.

Effects of Different Nutrient Solutions on the Acclimatisation of in vitro Caladium Plantlets using a Simplified Hydroponic System

An efficient acclimatisation protocol is critical to improve the survival rate and promote growth of in vitro plantlets. Herein, tissue-cultured plantlets of ‘Red Flash’ caladium (Caladium × hortulanum Birdsey) were treated with deionised water and three nutrient solutions including Japanese garden formula (JG), South China Agriculture University formula B for leafy vegetables (SCAU-B) and Hoagland solution in a simplified hydroponic system under indoor environmental conditions. The results showed that all the plantlets survived after 30 days of hydroponic culture, and the three nutrient solutions showed significant positive effects on the plant growth and the content of chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, soluble sugar and soluble protein compared to the deionised water treatment. No significant difference was recorded for the other growth parameters except the average leaf number per plantlet among the nutrient solution treatments. For the analysed physiological parameters, the plantlets treated by SCAU-B contained significantly higher content than those of the Hoagland treatment except the protein content. No significant difference was found between the JG and the SCAU-B treatment except the carotenoid content, and between the JG and the Hoagland treatment except the protein content. The plantlets acclimatised in the nutrient solutions also had a good performance when transferred to plastic pots. These results implied that water alone was not capable of maintaining healthy growth of in vitro caladium plantlets, and hydroponics approach using the three nutrient solutions could be a feasible method for acclimatisation of the plantlets.

The effect of different nutrient solutions on quality of cut tulips forced hydroponically

Tulips is one of the most popular plant species grown for cut flowers. Cut tulips are available on the market all year round, due to the development of forcing techniques of which the hydroponic method has recently been gaining popularity. The objective of the work was to evaluate the effect of different nutrient solutions on the cut flowers’ quality of two tulip cultivars – ‘Strong Gold’ and ‘Renegade’ forced on three dates, in February and March 2017. Three types of nutrient solutions were used (with calcium nitrate plus Universol Orange; with calcium nitrate alone; with calcium nitrate plus calcium chloride) while water was a control treatment. The length of stems and flower buds (cm) as well as the stem mass (g) were evaluated. When forced by the hydroponic method both cultivars gave a high commercial yield ranging from 93.5 to 100% and from 98.5 to 100% for ‘Strong Gold’ and ‘Renegade’, respectively. Visual evaluation showed that - regardless of the forcing date - both tulip cultivars forced in water (control) had leaves less coloured compared to those forced in the tested solutions. The tulips of both cultivars forced in water produced flower buds and stems of length and mass not inferior to or greater than those forced in the nutrient solutions, regardless of the forcing date. Stems of tulips variety ‘Renegade’ forced in water, as well as in the nutrient solution composed of calcium nitrate plus calcium chloride, were heavier than in tulips forced in the other nutrient combinations. As for the forcing dates, in the case of ‘Strong Gold’ the longer flower stems with longer flower buds and partly bigger mass were obtained on the last forcing in March 2017. In the case of ‘Renegade’, the above parameters were not related to a forcing date. As the extra supplementation with calcium and other nutrient compounds little affected tulip quality the studies of its effect on keeping qualities of cut flowers should be done before any recommendations concerning nutrient dosage increase are directed to the growers.

Farklı Besin Solüsyonlarının Yüzen Su Kültüründe Rokanın Verim ve Kalite Özelliklerine Etkileri

Teknelerde, havalandırmalı besin solüsyonu üzerine yerleştirilen köpük viyollerde yürütülen bu çalışmada, farklı besin solüsyonlarının rokada bitki gelişimi, verim ve kalite özellikleri üzerine etkisinin belirlenmesi amaçlanmıştır. Bengi F1 roka tohumları torf ortamına ekilmiştir. Her bir viyol gözüne (17 cc) 1 tohum gelecek şekilde (957 bitki/m2) ekim yapılmıştır. Çimlenme sonrası tohumlar adaptasyon serasına alınmış, çıkışlar tamamlandıktan sonra fideler su kültürüne aktarılmıştır. Bitkilerin beslenmesinde “tam doz” (komple besin solüsyonu: mg/L: N 150, P 50, K 150, Ca 150, Mg 50, Fe 5,0, Mn 0,50, Zn 0,05, B 0,50, Cu 0,03, Mo 0,02), “yarım doz” (makro elementleri %50 azaltılmış) besin solüsyonu ve “su” uygulaması kullanılmıştır. Ardışık 2 dönemde yapılan yetiştiricilikte her dönemde 3‘er hasat yapılmış, ilk hasattan alınan yapraklarda kalite analizleri gerçekleştirilmiştir. Sonuçlar iki dönem ortalaması şeklinde sunulmuştur. Elde edilen sonuçlar, bitki gelişimi, verim ve kalite özelliklerinin besin solüsyonu konsantrasyonuna bağlı olarak değiştiğini göstermiştir. Besin solüsyonu konsantrasyonu azaldıkça bitki gelişim ve verim değerlerinin azaldığı; renk ve toplam klorofil miktarlarının değişmediği, nitrat içeriğinin azalırken vitamin C içeriğinin arttığı saptanmıştır. Yaprak N, P, K ve Fe element içerikleri yarım doz uygulaması ile azalmış; Ca ve Mg‘da değişiklik olmamıştır. Ancak ölçülen birçok parametrede tam doz ve yarım doz uygulamaları arasında istatistiksel bir farklılığın olmadığı görülmüştür. Su uygulaması bitki gelişimi ve verim için gübreli uygulamalara göre yeterli bulunmamıştır. Araştırma sonucunda, rokanın yüzen su kültüründe yetiştirilebileceği, besin elementleri %50 azaltılmış yarım doz uygulamasının verimde önemli bir azalma meydana getirmeden gerek nitrat içeriğini azaltıp, vitamin C içeriğini arttırması ve gerekse daha az gübre kullanımına olanak vermesi nedeni ile tercih edilebileceği sonucuna varılmıştır.

The effect of different nutrient solutions on some growth indices of greenhouse cucumber in soilless culture

Today, greenhouse cultivation of vegetables, especially cucumber in soilless culture has been developed in different parts of the world. Soilless culture creates the possibility that farmers in a shorter time with less effort produce more yield. This research was done in the greenhouses center in Islamic Azad University of Khorasgan with three kinds of nutrient solutions and so completely randomized block design with three replication and five bushes per every replication was done. The media was composition of perlite and cocopite (v/v = 50%). Plant height, stem diameter, intensity of leaf colour, leaf area index, stiffness of fruit tissue, yield of fruits, dry matter weight were measured in every treatments. Comparison of means of cucumber fruit yield showed that there are no significant difference between solutions No 3, 2 and 1 in 5% level. The results showed that No 3 nutrient solution had most effect on the intensity of leaf colour, stem diameter, plant height and leaf area index as compared with other nutrient solutions during the growth season. No 2 nutrient solution had most effect on the weight of plant dry matter, weight of fruit dry matter and stiffness of fruit tissue. The height means of cucumber plants in treatments had no significant difference at 5% level. The comparison of stem diameter means showed that No 3 and 2 nutrient solution had significant difference at 5% level with No 2 solution but it had not any significant difference with No 1 nutrient solution at 5% level. The weight means of dry matter of fruit and green colour intensity of leaves had no significant difference between No 3 and 1 nutrition solutions but this nutrition solutions had significant difference with No 2 solution at 5% level. The comparision of leaf area index means showed that all of nutrient solutions had no significant difference at 5% level. The results showed that stiffness of fruit tissue in No 3 and 1 nutrient solutions had not any significant differences but between No 3 and 2 nutrient solutions had significant difference in 5% level. The means of dry matter weight of plant in No 3, 2 and 1 nutrient solutions had no significant difference in 5% level.

Produção hidropônica da cultura da alface com soluções nutritivas e vazões distintas

The experiment was conducted in protected environment, within a research unit in irrigated agriculture of the State University of Maringa, state of Parana. The purpose was to study the effect of different nutrient solutions applied on two outflows in the hidroponic production of lettuce (Lactuca sativa). The experimental design was entirely randomized, in factorial scheme 3x2 and with 3 replications. The treatments consisted of three nutrients solutions combined with two outflows of application in the canals of cultivation. In order to evaluate the effect of the treatments on crop growing, data were submitted to a variance analysis (Test F), and the results were evaluated through Tukey (5%) average test. The analysis of the results allowed to conclude that the interaction between the factors solution and the outflows was not significant and treatment S1 (CE = 1.2 dS m-1) showed higher fresh biomass, larger diameter of the stem and lower dry biomass of root

ドリテノプシスの生育とイオン吸収量に及ぼす培養液のイオン組成の影響

ミズゴケでドリテノプシスを栽培した場合の生育とイオン吸収に及ぼす培養液のイオン組成の影響について系統変量法を用いて検討した.葉中のクロロフィル含量は培養液中のイオン組成の影響を受けNO-3濃度の高い処理区で高くなった.生体重は培養液のイオン組成の影響を受け,K+の増加は茎葉部の生長を促進し,Ca2+の増加は茎葉の生長を阻害した.陰イオン組成は生体重に大きな影響を与えなかった.花序の生育も培養池のイオン組成によって異なった.陽イオン中のNH+4の増加によって満開日は早まった.陰イオンでは,SO2-4の増加は花序重を減少させた.ドリテノプシスのミズゴケ栽培における施肥組成の好適範囲は培養液濃度をΣMn±=8.5meq・liter-1とした場合,NH+4 16.6%～21.8%. K+ 38.3%～45.6%, Ca2+ 19.2%～24.9%, Mg2+ 17.0%, NO-3 64.8%～70.9%, H2PO4 10.7～13.7%, SO2-4 17.8%～22.3%となった.
