to study the effect of different weed control methods in tomato, an experiment was conducted as completely randomized block design with three replications at the research farm of university of tehran (karaj) in 2008. the treatments consisted of post emergence (at recommended rate) or pre emergence (reduced rate in combination with mulch) application of metribuzin, rimsulfuron and sulfosulfuron,...

Mulching technology has created a major problem of agricultural plastic pollution. This is because the mulch severely degraded by UV (ultraviolet) irradiation and mechanical properties deteriorate, which makes recycling or manual difficult. study was conducted on m-LLDPE (metallocene linear low-density polyethylene) films. The difference in specimens TD (transverse direction) PD (parallel inves...

Stale seedbeds are used by organic growers to reduce weed populations prior to crop planting. Ryemulches, derived from mechanically killed (rolled and crimped) winter rye cover crops, can serve the same purpose for spring-planted organic crops. Both methods can also be employed by conventional growers who face looming problems with herbicide resistant weeds. The objective of this research was t...

Blowing dust from summer fallow is a major soil loss and air quality concern in winter wheat (Triricum aesrivum L.) production areas of the inland Pacific Northwest (PNW). The objective of our 3-yr onfarm study in a 286-mm precipitation zone in eastern Washington was to determine the effects of tillage mulch depth during fallow on surface soil roughness, residue retention, seed-zone water stora...

This study tested the erosion mitigation effectiveness of agricultural straw and two wood-based mulches for four years on decommissioned forest roads. Plots were installed on the loosely consolidated, bare soil to measure sediment production, mulch cover, and plant regrowth. The experimental design was a repeated measures, randomized block on two soil types common in the northern Rocky Mountain...

A large part of the research carried out with strawberries (Fragaria × ananassa) has been with the aim of gaining higher yields. At the same time postharvest losses are remarkable. Therefore the need for research with the aim of increasing quality is rising. The aim of the present research was to study the influence of mulch (plastic and straw), fertilization and the age of plants (two, three a...

In recent years, North American prairie vegetation has served as a design model for highly attractive, low-cost and low-maintenance plantings in German urban green spaces. Where mixed-planting techniques, gravel mulch toppings and non-selective maintenance techniques such as mowing are used, prairie plantings are considered to be cost-effective alternative design concepts for public green space...
