Principally, plants grown in soilless culture may be attacked by the same pests and diseases as cultivated traditionally in soil. The most destructive phytopathogens are fungi, such as Phythium, Phytophthora and Fusarium, followed by viruses, bacteria and nematodes. We investigated effect of carbon nanotube filters on disease management of soilless culture. Tomato seedlings transplant in plasti...

abstract in order to provide optimal yield and quality of tomato fruit (lycopersicon esculentum mill. cv. beril), different growing media for soilless culture of tomato plants were studied. seedling of tomato (lycopersicon esculentum mill, cv. beril ) were cultivated in perlite, mixture of perlite with nh4-zeolite and with raw zeolite (z:p ratio 10v:90v) and fed by two nutrient sources: a) comp...

this study was conducted to investigate the effects of irrigation frequency and substrates on some parameters of greenhouse tomato (cv. hamra) during 1381-1382 at research greenhouse of agriculture college, in ferdowsi university of mashhad. the experiment was based on split plots in the form of completely randomized design and in four replications. irrigation frequency in three levels of 12, 8...

The previous chapters present various specific facets of soilless plant production, representing the state of the art and include some perspectives on the direction in which the field is moving. In some cases, gaps in knowledge were pointed out and required future research was suggested. Generally the chapters focus on particular facets of a system whose full complexity was beyond the scope of ...

Although we normally think about soilless culture as a modern practice, growing plants in containers aboveground has been tried at various times throughout the ages. The Egyptians did it almost 4000 years ago. Wall paintings found in the temple of Deir el Bahari (Naville 1913) showed what appears to be the first documented case of container-grown plants (Fig. 1.1). They were used to transfer ma...

The aim of this research was to evaluate butterhead lettuce quality in a soilless culture system. Butterhead lettuce cultivar “Lores” was cultivated, and two experiments were performed. In the first, floating system (FS) and soil culture (SC) were compared in fall (autumn) prduction [2002 2003], while in the second, substrate culture (PC) (plastic gutter filled with perlite) with three differen...

abstract colchicum kotschyi boiss (colchicaceae) is one of the sixteen iranian native colchicum species, containing considerable amount of colchicine. to study the effect of different nutrient levels on corm yield and colchicine content of colchicum kotschyi boiss under open field soilless culture, an experiment was performed in a randomized complete design at the horticultural research station...

one of the main constraints in aloe vera production is poor information about optimum nutrients that are helpful for growth and production. the objective of this study was to optimize nutrient solution for aloe vera cultivation in soilless culture. therefore, to determine the best nutrients the experiment was conducted in a greenhouse during 2011 in the agricultural faculty, university of guila...

Nowadays, most countries especially in arid and dry climate zones had experienced the water scarcity problems. In the agricultural sector, freshwater play a major role to supply water for the plant grows. Thus, the reuse of wastewater as alternative water resources in agricultural is highly recommended. However, wastewater is always contaminated despite after secondary treatment. Along benefici...
