“…Tomato and its products are rich in nutrients which are essential for human health (Adigun, Daramola, Adeyemi, Olorunmaiye, & Osipitan, ). Regular tomato consumption was found correlated with lowering the risks of some cancer types (Franceschi et al, ; Gerster, ; Javanmardi & Kubota, ; Weisburger, ) and heart diseases (Lavelli, Peri, & Rizzolo, ; Pandey, Shekelle, Selwyn, Tangney, & StamLer, ).…”

In this paper, comparative study on fresh and frozen tomatoes of organic and conventionally cultivated crops was performed. Fruits of tomato cv. Rio Grande© were used and stored at 18°C for 12 months. Quality parameters of ascorbic acid, lycopene, β‐carotene, glucose, fructose and proteins, pH, color, acidity, water‐soluble solids, and elements and azoxystrobine were measured. The results showed that amount of ascorbic acid and β‐carotene were similar in organic and conventional fresh tomatoes, but lycopene was found higher in conventional ones. Na and Mg were higher in conventional samples, but P, K, Ca, and Cu were higher in organic tomatoes. Organic samples were pesticide free, however, conventional fresh and 3 month stored tomatoes contained pesticides. Nitrite was not detected in any sample. These results show that organic products are healthier. Organic fresh tomatoes got the highest scores in sensory analyses. Practical applications Tomato is one of the most consumed fruits in the world. A comparative study was performed between organic and conventionally cultivated tomato fruits, in terms of some physicochemical and secondary metabolites for measure their quality properties and also investigated of effects on storage period both of the types of tomatoes. The results showed that serious reductions were observed after 12 month of storage at −18ºC in fruit quality criteria and antioxidant compounds, as well as nutritional parameters. Therefore, it can be recommended that conventional and organic tomatoes should not be stored longer than 9 months. Nutritive products with high yield and quality can be obtained through the optimization of controllable conditions. Further researches are needed about the effect of cultural practices such as irrigation and fertilization on the quality and nutritional value of fruit, both in organic and conventional growing systems.

“…Weed density (m -2 ), weed dry weight (g m -2 ), crop vigour score, canopy height (cm), number of leaves and branches per plant, leaf area index, number of pods and seeds per plant, pod and seed weight per plant (g), 100-seed weight (g) and seed yield (kg) were the parameters used to evaluate the performance of the treatments in both years. Crop vigour score was taken by visual observation based on the scale 0-10, where 0 represented plots with crops completely killed and 10 represented plots with the most vigorous growing and healthy crop (Adigun et al, 2018). Soybean dry weight was determined from five plants by destructive sampling within the net plot.…”

The effect of the period of weed interference on the growth and yield of soybean (Glycine max L. Merrill)

et al. 2020

Field trials were conducted to evaluate the effect of different periods of weed interference on weed infestation, growth and yield of soybean in 2016-2017 cropping seasons. In both years, soybean grain yields ranged from 888- 1148 kg ha -1 in plots where weeds were allowed to grow until harvest to 2103- 2389 kg ha -1 in plots where weeds were controlled until harvest, indicating a 52- 58% yield loss with uncontrolled weed growth. Weed interference until 3 weeks after sowing (WAS) had no detrimental effect on soybean growth and yield provided the weeds were subsequently removed. However, further delay in weed removal until 6 WAS or longer depressed soybean growth and resulted in irrevocable yield reduction, with the number of pods per plant being the most affected yield component. For optimum growth and yield, it was only necessary to keep the crop weed-free between 3 and 6 WAS.

Synergy between crop competition, agronomic practices and herbicides for effective weed control in plant production

Interaction of herbicide application with the manipulation of certain agronomic practices for crop competition, including sowing date and seeding rate, row and plant spacing, and application of fertilizers have the potential to reduce the abundance of agricultural weeds and optimize herbicide use. Sowing date and herbicide application play a significant role in determining growth, development and seed yield of many crops, as well as reducing weed density and weed biomass. Narrow row spacing can improve weed control because weeds are smaller and more easily controlled with herbicides than they are in wide row spacing. Furthermore, the more rapid crop canopy development of narrow row spacing reduces problems with late emerging weeds and may allow POST EM herbicides to be applied earlier in the season, therefore improving effectiveness and allowing reduced rates to control small weeds. Finally, adequate fertilization increases the vigour and competitiveness of the crop. By altering the time and method of fertilizing with herbicide application, competitive advantage can be shifted in favour of the crop.
