Weed control is one of the most labor-intensive tasks for organic vegetable farms, and a realtime crop recognition system is the main challenge to develop the automatic mechanical weeding system. One solution using time-of-flight (TOF) 3D camera and advanced computation technique based on FPGA is proposed to address this problem. It has great advantages and can work reliably in the real harsh w...

Weeds create a great problem for soybean production and to overcome this large number of weedicides are being applied prevalently worldwide. Gradually increasing the use chemical herbicides, not only creating resistance against these chemicals among weeds polluting environment, but also influencing main crop deteriorating produce quality. To focus two-year experiment was laid down during ‘khari...

Abstract Field studies were conducted in 2021 Kibler and Augusta, AR, to determine the effect of winter cover crops cultivar selection on weed suppression sweetpotato [ Ipomoea batatas (L.) Lam.] yield. The split-split-plot evaluated three [cereal rye ( Secale cereale L.) + crimson clover Trifolium incarnatum L.)], [winter wheat Triticum aestivum clover], fallow; weeding (with or without); four...

the environment” (Rice, 1984). Rice plants with an allelopathic effect on weeds can mean lower production To understand the genetic control of allelopathy in rice (Oryza costs because the need for herbicide application and/or sativa L.), quantitative trait loci (QTL) mapping was performed using a population of 142 recombinant inbred lines derived from a cross hand weeding is reduced. Thus, inco...

<span>In precision farming, identifying weeds is an essential first step in planning integrated pest management program cereals. By knowing the species present, we can learn about types of herbicides to use control them, especially non-weeding crops where mechanical methods that are not effective (tillage, hand weeding, and hoeing mowing). Therefore, using deep learning based on convoluti...

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...

The use of plantations to manage extensive tracks of deforested lands in the tropics is a conservation strategy that has recently received considerable attention. Plantation trees can promote seed dispersal by attracting dispersers and creating favorable site conditions, leading to increased germination and establishment of indigenous trees. Subsequently, plantation trees can be harvested for p...

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...
