introduction in dry areas, water is the limiting factor in improving agricultural production. saving the annual precipitation in the soil is very effective in dryland farming. the amount of rainfall that infiltrates the soil depends on the amount of soil permeability and runoff. the surface remains will be able to better permeable prevent runoff and raindrops and reduce erosion. in addition, ev...

The objective of this series of studies was to investigate the use of compost and mulch materials in erosion control and stabilization projects. The first phase of the study primarily looked at the impacts of surface blankets of twelve different compost and mulch materials on total solids (TS) loss and water quality and found that mulch blankets produced runoff with the lowest TS and nutrient c...

Polyethylene mulch with a reflective silver stripe and a yellow summer squash, Cucurbita pepo L., trap crop were tested alone and in combination as tactics to reduce densities of Bemisia argentifolii Bellows & Perring eggs and nymphs, and incidence of bean golden mosaic geminivirus on snap bean, Phaseolus vulgaris L. Egg densities were consistently higher on squash than on bean, but egg densiti...

In Southeast Asia, expansion of oil-palm agriculture, in combination with other industries (logging, fiber, and mega-dams), is transforming significant portions of the landscape threatening biodiversity, key ecosystem services, and human cultural diversity. While transformative answers to these multifaceted environmental issues seem daunting, the conservation biology literature provides a road ...

In this study, we have designed, fabricated, and characterized a miniaturized optical fiber-coupled terahertz (THz) endoscope system. The endoscopic system utilized a photoconductive generator and detector driven by a mode-locked Ti:sapphire laser. In reflection mode, the endoscope showed a high signal-to-noise ratio and a wide frequency spectrum similar to the conventional THz time-domain spec...

the trial randomized complete block design with four replications in summer 1394 in a farm located in the share ray to study the effects of different methods of weed control on the yield and quality of forage maize varieties (sc.704) was performed. the experiment consisted of black plastic mulch, black plastic mulch silver, vetch cover crop with a density of 100 per cent, with 50 per cent vetch...

This thesis investigates the mechanisms underpinning pleasant touch, describes a pathway from peripheral nerve endings in the skin to the insular cortex, and relates these findings to the subjective hedonic experience of touch. In Paper I, the relationship between primary afferent encoding and perception of pleasantness was investigated by combining microneurography recordings from human mechan...

A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...
