The simulated flora was translated into five weed harmfulness indicators (crop yield loss, harvest contamination, harvesting difficulty, field infestation, additional crop disease due to weeds) and five weed-related biodiversity indicators (weed species richness and equitability, weed-based trophic offer for birds, insects and pollinators).
The most interesting performance profile, which minimized all harmfulness indicators (except harvest contamination and harvesting difficulty) and maximized all biodiversity indicators (except species richness), was reached by a single strategy type, consisting of low or no-till systems.
In the short term, they considered the risks of yield losses and/or lower harvest quality plus harvesting difficulties.
Although lentil is a valuable source of protein for humans and its straw is a highly valued animal feed, its production in West Asia and North Africa (WANA) is limited due to harvesting difficulties, including uneven ripening, lodging, growing of pods close to the ground, and shattering of seeds and leaves at maturity.
The price of potatoes was down year on year, according to the survey, despite harvest difficulties caused by the long dry summer, which the agricultural development board has said led to an 8% average price rise in stores.
Planning of this nature avoids such problems as the lack of anchors from previously harvested units affecting current harvest, harvest difficulties when implementing visual management, or avoiding yarding through regenerated areas.
As with any new crop, we have experienced some challenges in our research including difficulty harvesting grain and weed suppression during the establishment year.
Here, child poverty rates are high and many workers who spend long days harvesting produce have difficulty putting food on their tables.
Federer highlighted several important factors to consider, including mixing of forest floor material into the soil during harvesting and the difficulty of distinguishing the boundary of the forest floor from the mineral soil.
There may be difficulty harvesting very curly hair, as the robotic needle cannot always accommodate the curvature of the follicles in these patients.
The Yao have the opposite problem: they have no trouble harvesting the nests but great difficulty finding them, since they tend to be tucked into burrows, hidden inside rotting tree trunks, or hanging, camouflaged, among zebrawood branches.
