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...

The influence of coloured-plastic mulching on physical and biochemical characteristics tomato fruits were investigated. During the study, crop was grown in an open field under five mulching, one organic mulch a no-mulch treatment. Harvested analysed for various physico-chemical post-harvest quality parameters. Results evidenced that sphericity tomatoe non-significantly (P<0.05) affected by h...

This study aimed to quantify forage yield, economic performance, biological efficiency and competitive ability in cactus intercropped with millet, compared their monocrops, both without mulch, under irrigation. The experiment was conducted over two years semi-arid of Brazil. experimental design randomised blocks four replications six treatments: monocropped mulch; millet mulch mulch. individual...

The choice of variety for agricultural systems with multiple crops may differ from the one used in sole crop because of the changes in environmental conditions brought about by interspecific plant competition. Information about varietal performance under living mulch conditions as well as the suitability of the results of the official variety testing, conducted under conventional cropping condi...
