Hydroponics basically is the method of growing plants using mineral nutrient solutions, in water, without soil. Vertical nutrient film technique (NFT) is one of the most used hydroponic technique that has constant flow of nutrient solution. In this study the effects of different support medium on strawberry quality and yield using vertical NFT in glass greenhouse was investigated. NFT-only system was compared to rockwool, coco fiber, perlite and expanded clay as supporting medium for strawberry production. Parameters such as weight of product, amount of product, rate of marketable product, and including physico-chemical properties such as pH, rigidity, color, dry matter amount, EC, vitamin C, sugar content, resistance to certain pathogens were observed among all supporting medium trials. NFT-only system significantly differed from other supporting medium trails by most of the parameters including fruit number per plant, average fruit weight, toughness of the fruit, vitamin C amount, sugar amount and finally soluble solid material amount in water . Revealing the effects of supporting medium on strawberry production shed light on how should NFT must be applied to fruit growing.

The traditional approach of soil mapping is time consuming and requires large amount of investments, especially for large scale areas, whereas the reflectance spectrometry for assessing the spectral behavior of soil has been an alternative [13]. This study aims to predict the moisture level in soil and significant wavelengths pointing the moisture existence with the help of satellite imageries and spectroscopic data. For that purpose. spectral profiles obtained from Advanced Spaceborn Thermal Emission and R...
Investigation of the impact of the nonlinear relations among soil moisture products over data fusion process
Afshar, Mehdi; Bulut, Burak; Yılmaz, Mustafa Tuğrul (2017-04-28)
Soil moisture is one of the terrestrial essential climate variables that has critical role in the water, energy, and carbon cycles. There are different ways available for the retrieval of this essential variable (e.g., remote sensing, hydrological models, insitu measurements, and etc.). However, the time series of these retrievals often contain systematic differences, which need to be removed via different rescaling approaches before these data sets could be used in data fusion type studies. In this study, ...
Investigation of the effects of initial substrate and biomass concentrations and light intensity on photofermentative hydrogen gas production by Response Surface Methodology
Akman, Melih Can; Bayramoğlu, Tuba Hande; Gündüz, Ufuk; EROĞLU, İNCİ (2015-04-27)
Biohydrogen, which can be produced by dark fermentation and photofermentation processes, is a renewable and clean approach for hydrogen production. In this study, it was aimed to determine the operational conditions which satisfy the highest photofermentative hydrogen production rate in batch reactors. To that purpose, the effects of initial substrate concentration, initial volatile suspended solids (VSS) concentration and light intensity on photofermentation process, and their interactive effects were inve...

Seeds of the plant quince are a natural hydrocolloid source whose extract has shown promising results in stabilizing emulsions. The study aims to discover how quince seed extract's interfacial properties (dynamic surface tension and dilatational surface rheology) on an oil–water interface change with varying concentrations (between 0.01% and 1%), pH's (3, 7, and 11), and ionic strengths (0.1, 0.3, 0.5 M NaCl). The lowest concentration that yielded a statistically significant drop in interfacial was found as...
Evaluation of CaCO3 clogging in emitters with magnetized saline waters
ŞAHİN, Üstün; Tunc, Talip; Eroğlu, Seçkin (2012-02-01)
High water application uniformity is essential for an effective irrigation. Clogging of emitters in drip irrigation systems is one of the most important factors decreasing uniformity. In this study, the possible effect of magnetization of water on chemical clogging of dripline emitters was investigated. Separate experiments were conducted with three different saline waters (W-1: 0.314 dS m(-1), W-2: 0.665 dS m(-1), W-3: 0.937 dS m(-1)) having a high pH and a positive Langelier saturation index (LSI). Discha...
