peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...

abstract leaving crop residues on the soil surface may significantly affect the behavior and activity of herbicides. to probe this effect, a factorial experiment in a randomized complete block design with three replications was conducted using two factors including different rates of wheat surface residue (0, 1250, 2500 and 3750 kg ha-1 ) and different rates of trifluralin (%48 ec) herbicide (7...

Title of Thesis: EVALUATING THE IMPACTS OF CROTOLARIA JUNCEA, SUNN HEMP, ON ARTHROPOD POPULATIONS AND PLANT GROWTH AND DEVELOPMENT IN A ZUCCHINI INTER-CROPPED AGROECOSYSTEM Jermaine L. Hinds, Master of Science, 2012 Thesis directed By: Professor Cerruti Hooks Department of Entomology Recently, studies have shown that crop diversification strategies can be effective and sustainable means of supp...

Field plots in Tifton loamy sand were treated with various soil pesticides in 1973 and 1974 and either left exposed or covered with biodegradable flint mulch. Test crops were cantaloup, slicing and pickling cucumber, squash, and sweet corn. Overhead sprinkler irrigation was used in 1973, and trickle irrigation under the film mulch was used on sweet corn in 1974. Soil was assayed for nematodes, ...

Aliphatic aromatic copolyester films, poly(butylene adipate-co-terephthalate) or PBAT, are susceptible to photodegradation, leading to main chain scission and crosslinking. The presence of crosslinked structures not only decreased the mechanical properties of the film due to embrittlement, but also hindered the biodegradation process by limiting access of water and microorganisms to the polymer...

Habitat manipulation in agroecosystems can influence predator–prey interactions. In this study, we collected foliar predators from field potato plots with different mulch treatments and assayed them for DNA of the target prey, Leptinotarsa decemlineata (Say), using species-specific primers. Concurrently, L. decemlineata larval abundance and plant damage were recorded from the same plots. Predat...

Husoak Village, Hubikiak District Jayawijaya is one of the regions in Papua province where plants including chili. The cultivation system are extensively and using traditional method depending on soil nutrients. aim research to see how utilizing a mix organic fertilizer mulch affects growth development chili plants. This was conducted based randomized block design consisting 4 treatments. namel...

To compare the soil water balance, yield and water use efficiency (WUE) of spring maize under different mulching types in the Loess Plateau, a 7-year field experiment was conducted in the Changwu region of the Loess Plateau. Three treatments were used in this experiment: straw mulch (SM), plastic film mulch (PM) and conventional covering without mulch (CK). Results show that the soil water chan...

The technology of freezing saline water irrigation (FSWI) with plastic mulching has been regarded as an effective way to reclaim the highly saline soil in coastal plains, which enabled the growth of crops in heavy saline soil that was not suitable for any crop growth before. However, after long-term treatment with FSWI, the microenvironment of the soil has been found to be affected by the growt...

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...
