Four studies were conducted in Georgia during spring 1999, 2000, 2001, and 2002 to evaluate various management tactics for reducing thrips and thrips-vectored tomato spotted wilt virus (TSWV) in tomato and their interactions relative to fruit yield. Populations of thrips vectors of TSWV, Frankliniella occidentalis (Pergande) and Frankliniella fusca (Hinds), were determined using flower and stic...
Urban stormwater runoff contains a broad range of pollutants that are transported to natural water systems. A practice known as biological retention (bioretention) has been suggested to manage stormwater runoff from small, developed areas. Bioretention facilities consist of porous soil, a topping layer of hardwood mulch, and a variety of different plant species. A detailed study of the characte...
A suitable instrument capable of inserting mulch into soil is needed to improve soil water holding capacity. The goal of this research is to design and manufacture an instrument with a blade and mechanism that can insert rice mulch into the soil. All the parameters in sub-soiling operation were taken into account, and the technique presented can be recommended as a special method of injecting r...
mulches bring several benefits to lettuce cultivation.a study on the lettuce ‘red rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. the experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. results showed that the...
Five selected insecticides were applied to four substrates and evaluated in laboratory studies for repellency and toxicity against the Pharaoh ant, Monomorium pharaonis (L.). We tested both repellent and nonrepellent formulations on outdoor (concrete and mulch) and indoor (ceramic and vinyl) substrates. Repellency was evaluated using a behavioral bioassay in which colonies were given a choice t...
Background: Present study, aimed to assess effect of organic and inorganic crop mulching on physical, physiological biochemical quality fresh cowpea beans.Methods: Cowpea (cv. Kashi Kanchan bush-type) was grown during two consecutive seasons from April 2018 July 2019 under four different treatments. Mulching treatments included no mulch; wheat straw mulch (organic mulch); black silver mulch. Bl...
Sustainable agricultural production is mainly attributed to healthy soils. Calcareous soils, especially in arid and semiarid areas, suffer from low organic matter nutrient availability. Low could degrade soil with reducing the crop productivity. Thus, present study aimed assess integrated effect of mulch irrigation on activity, availability, potentiality corn yield under calcareous conditions. ...
in the country, reducing water resources and increasing water losses in the various methods of surface irrigation, has increased attention, super drip irrigation method, especially drip tape irrigation. one of the techniques are used in cultivation of early sweet corn, the use of plastic mulch. using this technique, the reserve temperature conditions for plant growth and early maturity, resulti...
agricultural sustainability is closely related with the efficient use of natural resources, which are primarily transformed by the action of microorganisms. soil microorganisms are usually used as early indicators of soil quality since they rapidly respond to changes in soil management. a field experiment was carried out aiming to evaluate the effect of siratro (macroptylium atropurpureum), bah...
in order to effect of different mulch materials and optimal chemical, organic and biological fertilizer management on ecological agriculture characteristics in common purslane (portulaca oleracea l.) in khuzestan conditions, a filed experiment was conducted at experimental field of ramin agriculture and natural resources university in ahwaz, south-western of iran, during 2010- 2011 growing seas...
