Harrowing is often used to reduce weed competition, generally using a constant intensity across a whole field. The efficacy of weed harrowing in wheat and barley can be optimized, if site-specific conditions of soil, weed infestation and crop growth stage are taken into account. This study aimed to develop and test an algorithm to automatically adjust the harrowing intensity by varying the tine...

Weed infestation is an essential factor in sugarcane productivity loss. The use of remote sensing data conjunction with Artificial Intelligence (AI) techniques, can lead the cultivation to a new level terms weed control. For this purpose, algorithm based on Convolutional Neural Networks (CNN) was developed detect, quantify, and map weeds areas located state Alagoas, Brazil. Images PlanetScope s...

In rice (Oryza sativa L.) culture the effect of puddling (wet tillage) on puddle quality, weed growth and yield of crop depends upon initial soil manipulations by pre-puddling tillage. However, the role of pre-puddling tillage on these aspects has not been studied adequately. These effects were studied for three years (1994±1996) in a ®eld experiment with a rice±wheat (Triticum aestivum L.) cro...

Weed seeds may maintain their viability when passing through the digestive tract of cattle and can be therefore dispersed by animal movement or the application of manure. Whether different cattle types of the same species can cause differential weed seed fate is largely unknown to us particularly under non-grazed systems similar to Holstein-Friesian dairy farming. We investigated the effect on ...

Differences in soil and habitat conditions, depending on the type of soil on which shrubby species of willow Salix L. are being grown for energy purposes, are reflected in weed infestation species diversity and the distinctiveness of these crops, and require an individual program of control and reduction of the abundance of competitive herbaceous vegetation. Our study aimed at determining soil ...

in order to evaluate the effects of crop cultivars and living mulchon sunflower yield and weed control, a field experiment was carried out as factorial arrangement based on a randomized complete block design with three replications in 2013. treatements were sunflower cultivars (‘azargol’, ‘allstar’, ‘farokh’) and weed control treatments (weed-free, weed-infestation and intercropping of fagopyru...

In field trials planted in the Midlands North and Gingindlovu areas, Melinis minutiflora Beauv. was intercropped in various ways with sugarcane in fields bordered by Cyperus dives C.B. Cl. to determine whether the presence of this grass reduced Eldana saccharina Walker numbers and infestation levels in sugarcane. Results showed E. saccharina populations were decreased by up to 50% and E. saccha...
