“…The weed species comprised eight types of broadleaf weeds, six types of grasses, and two types of sedges (Table 1). The prevalence of both annual and perennial broadleaf weeds and grasses in this study may be as a result of the high disturbance environment that favors them (Menallad et al, 2001;Daramola et al, 2021). However, there were differences in the level of weed infestation between the two years.…”

Weed interference is a major threat to rice production, leading to high yield reduction and reduced profitability. Therefore, field experiments were conducted to evaluate the effect of the different timings of weed control on the growth and yield of upland rice in the 2015 and 2016 cropping seasons. The treatments consisted of periods when the crop was allowed to be weed-infested for the first 3, 6 and 9 weeks after sowing (WAS) and periods when the weeds were controlled for the first 3, 6 and 9 WAS. Two treatments of weed infestation and weed control until harvest were also included as the checks in a randomized complete block design with three replications. In both years, rice grain yields ranged from 0.6 to 0.8 t ha-1 in plots kept weed-infested until harvest, and from 3.5 to 3.9 t ha-1 in plots kept weed-free until harvest, indicating a 79-83% yield loss with uncontrolled weed growth. Weed infestation for the first 3 WAS did not cause a significant reduction in the growth and yield of rice provided the weeds were removed thereafter. However, the delay in weed control until 9 WAS reduced rice growth and resulted in irrevocable yield reduction. It was only necessary to remove the weeds between 3 and 9 WAS for optimum grain yield, as no significant yield increase was observed in weed control after 9 WAS in both years. This study showed that weed control between 3 and 9 WAS would give the optimum growth and yield of upland rice.

“…Weeds are one of the most important pest that reduces crop productivity. Weeds and crop plants are very similar in their demand for carbon dioxide and nitrogen from the atmosphere, water and minerals from the soil and light from the sun for their growth and development [1]. When weeds compete for these restrictive resources, the growth and development of crops are restricted, and their yield and productivity drastically reduced.…”

“…However, these weed management systems have a number of limitations. Hand weeding is tedious, inefficient, time consuming and associated with high labor demands [1,7,8]. In addition, labor for manual weeding is scarce and often too expensive [1,2,9].…”

“…Therefore, the adoption of integrated weed management (IWM) strategy is more advantageous than relying on one form of weed control. IWM involves the reduction of weed interference through a combination of two or more methods while maintaining acceptable crop yields, environment, social and economic wellbeing [1,19]. However, in literature, information on weed interference and management methods, especially IWM strategy for improved productivity of cucumber is very scattered and not available in the form of a single document.…”

Cucumber Economic Values and Its Cultivation and Breeding

Weed interference is a major problem in cucumber farming, leading to 45–95% yield reduction. Weed control practices employed to avoid such losses are predominantly hand weeding and herbicides application. All the weed control methods used in cucumber farming have their own limitations. Hand weeding is tedious, time consuming and associated with high labor demands. Only few herbicides are registered for weed control in cucumber, and these herbicides does not provide season-long weed control when used alone, neither can they control the entire weed spectrum with diverse physiology, morphology and time of emergence. Therefore, to optimize yield, financial and environmental costs and benefits, integrated weed management approaches are advocated. A good tillage operation, use of competitive cultivars, appropriate plant population and row spacing, application of pre and post emergence herbicides are important in reducing weed density. The combination of these approaches provides effective weed control, and helps in environmental conservation. The world is now moving toward precision weed management techniques which involve remote sensing, modelling and use of robotics to control weeds. These technologies are the future of weed management in crop production and have a substantial role to play in modern cucumber production. Right selection of one or more of these techniques with reference to environmental, socioeconomic, and geographic conditions will provide effective weed control in cucumber. Future research should therefore be focused on delivering information for the implementation of these approaches.
