Development of an autonomous weeding machine requires a vision system capable of detecting and locating the position of the crop. It is important for the vision system to be able to recognize the accurate position of the crop stem to be protected during weeding. Several shape features of corn plants and common weed species in the location were extracted by means of morphological operations. Eff...

The effect of some weed control treatments (Bifonex, Tribenuron-methyl, hand weeding and unweeded check), five wheat cultivars (Sakha 69, Sids 6, Sids 7, Sids 8 and Sids 9) and their interaction on the productivity of wheat plants and associated weeds were examined under the sandy soil conditions. The obtained data indicated that total dry weight/m2 recorded at 60 days from wheat sowing signifi...

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...

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...

In Bangladesh during 2017-2018 was conducted in a farmer's field of the Chattogram hill districts to determine effectiveness different weed control strategies for transplanted chilli. The dry weight weeds, efficiency, index, and yield components like number fruits per plant, fruit length, weight, marketable yield, had been significantly affected by using measures. act treatment chilli fields, h...

I vividly remember the lecturer who attempted to teach me statistics as an undergraduate. The poor man tasked with imparting such vital knowledge alas had no ability to engage a large class of budding biologists. Each lecture he mumbled his way through his notes, writing out long, incomprehensible equations on the board, as paper aeroplanes bounced off his back. Talking to other biologists, it ...
