How to Increase Potato Tuber Size and Yield
The main challenge for farmers at the end of the tuber initiation phase is to achieve a high number of tubers above 15 mm. Any tubers that do not reach this size shrink and disappear. The main challenge after the tuber initiation phase is to optimise the reserves and obtain a maximum of marketable ...

Effects of silicon and drought stress on tuber yield and leaf biochemical characteristics in potato
Silicon has beneficial effects on many crops, mainly under biotic and abiotic stresses. Silicon can affect biochemical, physiological, and photosynthetic processes and, consequently, alleviates drought stress. However, the effects of Si on potato (Solanum tuberosum L.) plants under drought stress are still unknown. The objective of this study was to evaluate the effect of Si supply on some ...

Rotational and cover crop determinants of soil structural stability and carbon in a potato system
Understanding processes that ameliorate structural degradation in sandy soils is particularly important in intensively managed potato (Solanum tuberosum L.) systems. Seven 2-yr potato rotation systems were evaluated over 3 yr in an irrigated field trial comparing winter management systems bare (B) and cover crops: rye (Secale cereale L.; R), rye-hairy vetch (Vicia villosa Roth; RV) mixture and ...

Advantages of auxin analogues as plant growth and productivity regulators
The possibility of regulating productivity of potato plants by applying the promising analogues of auxin compounds TA-12, TA-59, LN-14, LN-16 has been proved experimentally. The compounds at optimal concentrations (TA-12 1.0, TA-59 0.5, LN-14 and LN-16 1.0 kg/ha) were found to activate the process of tuber formation, increasing the number of tubers and accumulation of assimilates in tubers. TA-12 ...

Effects of low concentrations of herbicides on full-season, field-grown potatoes
Current phytotoxicity plant test protocols for US pesticide registration require testing for effects on seedling emergence and early growth without regard to other important factors, such as plant reproduction. Yield and quality reduction can have significant economic and ecological effects. Therefore, field trials were conducted to determine if potato (Solanum tubersum L.) vegetative growth and ...

One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas
All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. This figure doubles when looking at irrigated cropland, which produces 40 ...

Potato Late Blight, Lelystad, Netherlands - Case Study
Late blight, caused by Phytophthora infestans, is the most important disease in potato production. Under favourable conditions the pathogen can destroy the potato foliage very rapidly and cause tuber blight. To avoid infection of the foliage, fungicides are frequently sprayed onto the crop. In the Netherlands, in some years up to 15 sprays are necessary to prevent the crop from infection by the ...

Detecting plant root diseases & pests
Soil-borne pests and diseases are harder to detect than those on the aerial parts of a plant. Visible symptoms in leaves and stem appear only in the final stages of the attacks. If plants are treated at this point, it may be difficult to avoid plant injury, as plants could already have been severely impacted. Early detection and identification are key to prevent crop loss. There are, however, ...

Seasonal slug pressure warning – crops at greater risk
Crops face a greater risk of slug damage and if left untreated, this can become extremely expensive for farmers, and is estimated to cost the potato industry up to £53 million per year*, as any slug damage reduces saleability and ultimately profitability of a crop. Slugs are most damaging to potatoes during the early stages of tuber bulking, which is starting to happen now. So make sure ...

Italian ryegrass management effects on nitrogen supply to a subsequent potato crop
There is increasing use of Italian ryegrass (Lolium multiflorum Lam.) as a green manure in potato (Solanum tuberosum L.) rotations; however, effects of its management on soil N supply to the subsequent potato crop are unknown. Fertilizer N management and plow-down date for a preceding Italian ryegrass crop, ‘Lemtal’, on soil N supply to a subsequent potato crop, ‘Russet Burbank’, was determined ...
