Potato yield and quality response to subsoil tillage and compaction
Compacted soils have been found in intensively cultivated vegetable crop regions of Central Wisconsin, resulting in the wide scale use of subsoil tillage by growers. The goal of this project was to assess potato (Solanum tuberosum L.) yield and quality response to soil compaction and subsoil tillage. Potato quality factors evaluated were marketable yield, tuber size distribution, internal ...

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 ...

Second generation European corn borer injury and Irish potato physiology, yield, and quality
European corn borer (ECB) [Ostrinia nubilalis (Hübner)] (Lepidoptera: Crambidae) is known to infest Irish potato (Solanum tuberosum L.) but only causes economic damage during the first generation in East Coast potato producing areas. However, in Nebraska, second generation ECB infest potato plants during the bulking period and may reduce yield and/or potato quality. Experiments were conducted in ...

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 ...

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 ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...

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 ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil
Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

4 tips for successful potato establishment this spring
Alistair Neill, a Prime Agriculture potato agronomist based in Norfolk, shares his four essential tips on getting potato crops off to the best start possible, beginning with ensuring good crop establishment.1. Cut back on cultivations Soil compaction can jeopardise potato establishment and yield because it restricts root growth, consequently limiting water and nutrient uptake. Therefore, if it’s ...

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 ...

Latest Potato Field Trials Show Excellent Yield Results
We have seen some excellent results in our 2016 potato field trials. Trials undertaken by growers in Cambridgeshire and Lincolnshire on four varieties: Markies, Maris Piper, Sagitta and Divaa have shown yield increases averaging 20% with the use of multi-nutrient phosphite PK MAXX+. Increases in tuber size, uniformity and yield Treated trial plots outperformed control plots on yield, tuber ...

Field degradation of aminopyralid and clopyralid and microbial community response to application in Alaskan soils
High latitude regions experience unique conditions that affect the degradation rate of agrochemicals in the environment. In this study, data collected from two field sites in Alaska (Palmer and Delta) were used to generate a kinetic model for aminopyralid and clopyralid degradation and to describe the microbial community response to herbicide exposure. Field plots were sprayed with herbicides ...

Principle and Process of Sweet Potato Starch Production
Sweet potato, also known as sweet potato, sweet potato, hawthorn, red glutinous rice, etc., is an excellent raw material for starch processing. The sweet potato starch production process is actually a physical separation process, which separates the cellulose, protein, inorganic salts and other substances in the raw materials from the starch. In the production process, starch is separated from ...
