Effect of Nutrients Composition on The Growth Parameters Two Lettuce Varieties in Hydroponic Culture With Solid Growing Media

The research aims to determine the effect of consumer behavior on purchasing decisions for hydroponic vegetables at Puccan Hydroponics. results analysis show that there are 4 factors considered, namely Product, Price, Place, and Promotion Purchase Decision using multiple linear regression analysis. population is vegetable consumers Hydroponics with a total sample 30 respondents. sampling techni...

The garden plant portulaca (Portulaca oleracea cv.) efficiently removes bisphenol A (BPA), an endocrine-disrupting chemical, from a hydroponic solution, but the molecular mechanisms underlying BPA metabolism by portulaca remain unclear. In this study, BPA metabolites converted by portulaca were analyzed by liquid chromatography coupled with tandem mass spectrometry. We observed the hydroxylatio...

Vigorous plant growth without sunlight is routinely achieved in commercial hydroponic lettuce and tomato production using electric lamps. This same technology can be used to maintain live turf grass in closed athletic stadiums. It can also be used to supplement natural sunlight in retractable roof stadiums. The challenge is to determine the optimal combination of genetic characteristics and env...

In this case study we present the design of a functional prototype of an intelligent hydroponic greenhouse that allows to grow fruits, like tomato, at any time of the year, manipulating specific variables such as temperature and humidity of the microclimate inside the greenhouse. The objectives of the present case study are to analyze the parts that compose the prototype as it is the structure ...

NADP(H)-dependent glutamate dehydrogenases (GDH) in lower organisms have stronger ammonium affinity than those in higher plants. Here we report that transgenic rice overexpressing the EcGDH from Eurotium cheralieri exhibited significantly enhanced aminating activities. Hydroponic and field tests showed that nitrogen assimilation efficiency and grain yields were markedly increased in these trans...

In the studies of nutritional absorption and metal toxicity in the root, it is important to grow plants without technical damage. We established a simple hydroponic culture system for Arabidopsis thaliana to obtain a healthy plant having a well-developed root system with many lateral roots. The phytotoxic effects of Cr, Cu, and Al ions were examined by FDA-PI staining using this culture system....

Inoculation of Phaseolus vulgaris with Azospirillum brasilense Cd promoted root hair formation in seedling roots and significantly increased total and upper nodule numbers at different concentrations of Rhizobium inoculum. In experiments carried out in a hydroponic system, A. brasilense caused an increase in the secretion of nod gene-inducing flavonoids, as was observed by nod gene induction as...
