This study was conducted to estimate the yield, and identify quantify primary secondary metabolites in fruit of Malus domestica Borkh. cv. ‘Sampion’ under two agrotechnical factors: floor management (herbicide fallow living mulch) dose nitrogen (50, 80, 110, 140 kg ha−1). Compared herbicide fallow, mulch did not decrease yield. Research showed a rich composition phenolic volatile organic compou...

Agricultural plastics area significant contributor to solid waste disposal problems, particularly in areas with heavy use of plastic-covered greenhouses or mulch films. Fieldburning and landfilling are no longer viable options for disposal in many areas. Reuse and reduced weight of films are two methods to reduce the amount of material requiring disposal. Recycling, incineration, and on-site de...

One of the principal components of the contaminant load in urban stormwater runoff is oil and grease (O&G) pollution, resulting from vehicle emissions. A mulch layer was used as a contaminant trap to remove O&G (dissolved and particulate-associated naphthalene, dissolved toluene, and dissolved motor oil hydrocarbons) from a synthetic runoff during a bench-scale infiltration study. Approximately...

Improving water use efficiency and soil properties are two major factors for sustainable development in desert areas. Therefore, this research aims to study the effectiveness of a biological hydrogel, plant vegetation layer, sand and barley straw with rain harvesting techniques through micro-catchment operation on some soil properties including pH, Nitrogen, Electrical conductivity, Sodium Abso...

abstract to study the effects of four types of mulches including wood chips, municipal compost, sawdust and gravel in three different thicknesses on growth of platanus orientalis during two years, an experiment was conducted in mashhad area with semi-arid climate. the research was conducted as split plot based on a completely randomized block design with four replications. treatments included c...

An experiment was designed to test the effects of metalized UV reflective silver plastic mulch on insect populations on a tomato crop as compared to the standard black plastic mulch. Yellow sticky cards, replaced weekly from June 8 to July 12, were used to collect flying insects, which were counted and classified. The total number of insects, and insects in the Thysanoptera, Homoptera, Aphidida...

Tomato spotted wilt virus (TSWV) is a Tospovirus affecting field tomato crops worldwide. The virus is transmitted by some species of thrips. The most damaging vectors in Italy are Frankliniella occidentalis and Thrips tabaci. Only the first instar larvae can acquire the virus from an infected plant. After acquisition, the virus replicates in the vector, and the viruliferous thrips is capable of...

in the absence of herbicides, cover crops play an important role for weed management in organic than in conventional farming. therefore, in order to evaluate the effects of cover crop management and plant density of buckwheat (fagopyrum esculentum) as cover crop on weed suppression, a field experiment was conducted at the research farm of university of zanjan, during the growing season of 2011....

employment of solarization using the polyethylene mulch can be effective as a non-chemical approach for some control noxious weed management such as purple nutsedge (cyperus rotundus). in order to determine the effect of different levels of polyethylene mulches including one- layer clear polyethylene film, two- layer clear polyethylene film, one- layer black polyethylene film and two- layer bla...
