One factor limiting the achievement of high yields in soybean crop is weed interference. The level interference can vary according to specificities community but also due agronomic characteristics varieties. objective this work was evaluate effects on varieties different relative maturity groups (RMG). A field experiment implemented a randomized complete block design, 3 × 4 factorial scheme, wi...

in order to investigate the effect of chemical herbicides on control of broad leaf weeds of common bean, an experiment was conducted in 2007 at yasouj with 12 treatments in a randomized complete block design with 3 replications. treatments consisted of preplant application of trifluralin herbicide at 960 g ai ha-1; postemergence application of bentazon at 1200 g ai ha-1; imaztapir at 50, 75 and...

One of the wood industry activities in forestry sector is Eucalyptus sp at PT.Riau Mainstay Pulp and Paper Riau Province. The production process used for pulpand has many factors its productivity. them planting with weedcontrol problems, which use herbicide active ingredient glyphosate. glyphosate not effective against all types weeds. Therefore, it necessary to know right combination weed cont...

A key enabling factor for treating individualized weeds in the crops is Automatic Weeding Control device (AWCd) as it being capable of finding and distinguishing field. The non-herbicide approaches used to manage are a component personalized treatment weed crops. In this study, mechanical control techniques investigated an alternative. three specifications—a cutting mechanism, head-surface till...

North American prairie vegetation has been a role model for designing highly attractive plantings for German urban green spaces for the past decade. In combination with gravel mulch top layers on planting sites and non-selective maintenance techniques like mowing or burning, prairie plantings are considered to be cost-effective and low-maintenance. This study was undertaken to assess the impact...
