Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic and inorganic substrates obtained more important for greenhouse owners and researchers. The aim of this study was Effects of culture substra...

Lumber used to construct raised garden beds is often treated with chromated copper arsenate (CCA). This project aimed to determine (i) how far As, Cu, and Cr had diffused away from CCA-treated wood surfaces in raised garden beds under realistic conditions, (ii) the uptake of these elements by crops, and (iii) the effect of CCA solution on soil bacteria. This study showed that As, Cu, and Cr dif...

Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...

The human-health risk posed by gardening near a legacy mine and smelter in an arsenic-endemic region of Arizona was characterized in this study. Residential soils were used in a greenhouse study to grow common vegetables, and local residents, after training, collected soil, water, and vegetables samples from their home gardens. Concentrations of arsenic measured in water, soil, and vegetable sa...

Vine leaves are considered a delicacy food however they only produced as byproduct for short harvest period due to grape cultivation practices and numerous chemical applications. In this work, vine plants were cultivated hydroponically in greenhouse, extend the along with high plant density, maximize fresh yield. Four different substrates tested—Perlite, Perlite-Attapulgite, Perlite-Zeolite, 1....

Amylases are among the most important enzymes and are of great significance in present day industry. Starch degrading bacteria are most important for industries such as food, fermentation, textile and paper. Amylase is a hydrolytic enzyme and in recent years, interest in its microbial production has increased dramatically due to its wide spread use in food, textile, baking and detergent industr...

garden asparagus is thought originally to be native in eastern Europe or western Asia, perhaps in or near the Caucasus, although it is widely naturalised inland and on the coast.” But wild asparagus is becoming increasingly rare. It is found only on the coasts of northern Spain, northwestern France, Belgium, the Netherlands, the UK and Ireland. And some of the known populations comprise as few ...

Soil-borne pathogens are posited to maintain forest diversity. However, their in situ impact and spatial variation are largely unknown. We examined spatial patterns of pathogenic activity in a deciduous forest using a common garden experiment and also in a natural experiment around replicated trees, and we quantified Pythium (a soil-borne pathogen) density around individual Prunus serotina tree...

In order to understand the heavy metals accumulation and transfer in a plant-soil system in sewage sludge applied soils, 15 familiar garden plants (including 7 herbages, 5 shrubs and 3 arbor species) were planted in soil with sewage land application at the experimental site in Shanghai, China. The experiment measured the changes in 7 heavy metals (Zn, Cu, Ni, Cd, Pb, Cr and As) fractions and co...

An apparent physiological disease, Yellow Strapleaf (YSL) of Chrysanthemum morifolium Ram., was described by Jackson and Woltz (1) in 1959. The disease has been observed in Florida plantings during the last 6 years and has been noted in Massachusetts 3. Symptoms include chlorosis of new growth, green netting of leaves, and narrow strapshaped leaves that hook at the distal ends (fig 1A). The con...
