This information is of immense significance in view of high cost of weed control measures.
competitiveness against weeds would provide a low-cost and safe tool for an integrated weed management strategy.
When weed control is satisfactory and herbicide costs relatively comparable, yield potential of the cultivar and seed cost, including any technology fee, would be key factors in selecting a weed management system.
This is important for the selection of cost-effective weed control strategies.
The greatest direct cost to the producer occurs during the first year of poor weed control.
Many national schemes for setting priorities for invasive weed management have emphasized the current or future impacts of the weed more than the cost or feasibility of control, perhaps because the latter may be difficult to estimate.
If so, it will be imperative to preserve efficacy of acceptable weed control methods by defending these against weed adaptation.

How cost effective are sports?5 answersSports have shown varying degrees of cost-effectiveness based on different interventions and settings. Studies have highlighted the potential cost-effectiveness of sports interventions in different scenarios. For instance, a study on programmed sports therapy (PST) for people with haemophilia demonstrated a significant gain in quality-adjusted life-years (QALYs) and a potential to reduce healthcare costs, indicating the cost-effectiveness of such interventions. On the other hand, community-based sports interventions have shown that less intensive sports sessions may be more effective and cost-effective in increasing physical activity among inactive individuals, with a cost per QALY of £50,000 for certain interventions. Additionally, the form of management in sports services can impact cost efficiency, with direct municipal management being identified as the most efficient delivery form in some cases.
Is hydroponics cost effective?5 answersHydroponics has the potential to be cost-effective. It offers advantages such as shorter crop growth times, year-round output, low disease and insect attack, and reduced labor-intensive procedures. Low-cost hydroponic systems have been developed for growing coriander, which can increase production per unit area economically. Simplified hydroponics, using locally available materials and a new nutrient formulation, has been shown to be cost-effective for growing tomatoes. A low-cost device for single plant culture hydroponics has been successfully used to grow roses, with significant correlations observed between root and shoot growth parameters. Additionally, the proposal of a self-sustained IoT-enabled hydroponics farm aims to optimize natural resources and increase yield and profits for farmers. Overall, these studies suggest that hydroponics can be a cost-effective method for crop production.

Can the germination of green pepper seeds be affected by the presence of neem oil?
5 answers
The germination of green pepper seeds can indeed be influenced by the presence of neem oil. Research has shown that neem seed oil has the potential to affect the germination process of seeds. Neem oil has been found to exhibit allelopathic effects, impacting the germination percentage, speed index, and root and hypocotyl length of seeds, as observed in experiments conducted with pasture seeds. Additionally, neem seed oil has been shown to inhibit the transmission of potato virus Y to sweet pepper plants, suggesting its interference with virus acquisition and inoculation processes. However, it is important to note that while neem seed oil can reduce pest populations, it may also have deleterious effects on beneficial predators like Eriopis connexa.
