Symptoms of the disease were observed on the leaves during growth and in tubers after harvest and after storage

A novel cropping system for potato was tested for two consecutive years under normal Dutch agronomic conditions. Seedlings from two experimental genotypes of hybrid true potato seeds were produced in a greenhouse nursery and transplanted into the field 5 weeks after sowing to assess tuber yield levels and to study effects of hilling on tuber yield and number, tuber size distribution and tuber greening

Potato has been recognized as a crop of importance in developing countries for ensuring human nutrition and food security. The dwindling natural resources, low fertility of soils, the incidence of pests and diseases, climate change and lack of strategic planning pose major constraints for potato production in these countries. Crop models are efficient tools for assisting research and development efforts

Crop evapotranspiration (ETc) estimation is essential for many studies such as irrigation system design and management, crop yield simulation, and water resource planning and management. Field studies were conducted at MPKV Rahuri, Maharashtra from 2015 - 2016 and 2016 - 2017 (2 years) in clay soils to determine crop evapotranspiration and crop coefficients (Kc) of the potato crop. The experimental

Potato growers suffer losses due to potato soft rot and blackleg caused by pectinolytic bacteria of different species. These bacteria cause yield loss during cultivation and storage, and can be transmitted to the next generations through seed tubers. The prevalence of Pectobacterium atrosepticum has decreased over the last 20 years in Europe in favour of Dickeya solani and P. carotovorum subsp. brasiliense

In the coastal region of the Ganges Delta, rice is the predominant crop during the wet/kharif season and most of the land remains fallow during dry/rabi season due to soil salinity and irrigation water scarcity. Sustainable intensification of coastal saline land needs an improved package of practices which conserves soil moisture, facilitates early crop establishment, ensures profitability and has

Potato (Solanum tuberosum L.) is an important food and cash crop of India. An important constraint in potato cultivation in Deccan Plateau of India is non-availability of quality seed tubers. Many certified cultivars are readily available, but their quality check pertaining to viral infection is neglected. This study was made to determine the infection level of potato viruses in certified seed potatoes

The length of tuber dormancy of potato (Solanum tuberosum L.) is an important property of cultivars, which significantly determines the duration of storage period, the storage conditions, the economy of storage and the earliest time of planting. Potato cultivars can largely differ in the duration of dormancy period. Under temperate climatic conditions, longer dormancy is more advantageous. However

The most important potato viruses in Uganda are Potato virus Y (PVY), Potato leafroll virus (PLRV), Potato virus X (PVX), Potato virus S (PVS), Potato virus A (PVA) and Potato virus M (PVM). Utilization of R genes in breeding for resistance to viruses has not been explored in Uganda due to limited information on the prevalence of R genes in the available genotypes. This study aimed at identifying potato

When frying foods, volume changes appear as shrinkage that can affect their physical properties including density and porosity, which are both important factors for heat and mass transfer. Challenges faced in heat and mass transfer while processing foods are associated with shrinkage. It is thus necessary to analyse and quantify structural changes in foods (such as shrinkage) to better understand the

To evaluate the influence of agro-climatic conditions on glycoalkaloid content, the potato clones were grown for two consecutive

In potato cultivation, the problem of controlling broadleaf weeds could be solved with the production of plants resistant to the broadleaf herbicide bentazone. Plant tissue culture technology and herbicide screening technology were used to select bentazone-resistant potato materials and to analyse the physiological and biochemical characteristics of their resistance. Potato microtubers were used as

Chemical agricultural inputs (e.g. pesticides and fertilizers) pollute the environment and undermine food safety. In fact, agriculture is in a direct relationship with the environment and farmers’ behaviours have extensive positive or negative impacts on it. Therefore, enhancing farmers’ behaviours to go towards organic farming methods represents a promising approach. The present study aimed to explore

This study assessed the feasibility of providing a regular supply of locally produced potatoes during landlocked winter months in Ladakh region. Potato tubers were stored (January–May) in semi-underground stores where conditions were between 0.2–13.6 °C and 87–96% relative humidity. Periodical sample analysis was carried out on sensory attributes and the physicochemical attributes firmness, sprouting

South Africa harbours many small-scale potato growers who produce for home consumption and local markets using variable levels of inputs (seed, nutrients, water). We assessed potato production practices, input resource use and use efficiencies, farm characteristics and yield gaps on smallholder potato farms in the KwaZulu Natal and Mpumalanga Provinces of South Africa through a survey and a crop model

Potato (Solanum tuberosum L.) being a vegetatively propagated crop is infected by a large number of viral diseases, most of which are transferred over generations through planting material (tubers), duly responsible for degeneration of seed stocks over the years. In the recent past, the most important geminivirus infecting potato has been Tomato Leaf Curl New Delhi Virus-Potato (ToLCNDV-Potato) or

An experiment was performed to study the impacts of elevated CO2 concentrations and climatic warming on potato growth during 2016.

Fifty-two phytoplasma symptomatic potato plants were

The field efficacy of liquid formulations of Pseudomonas fluorescens, Purpureocillium lilacinum and Trichoderma viride was investigated against natural populations of potato cyst nematodes (PCNs) Globodera rostochiensis and Globodera pallida. Two field experiments were conducted using these biocontrol agents applied as seed treatment (ST) at 1 L t−1 of seed and soil drenching (SD) at 5 L ha−1. Their

Potato (Solanum tuberosum L.) is considered a drought-sensitive crop species, although cultivar-dependent differences in tolerance have been described. The extent of drought-induced tuber yield decreases is considered the main criterion for potato tolerance to drought. In this study, eighteen closely related potato cultivars were subjected to drought stress, and among them, two groups with contrasting

The use of a cold storage plant for reducing perishable food losses is insufficient in developing and underdeveloped countries because of required infrastructure and investments. For this reason, many producers continue to store foods with traditional methods, which can lead to considerable food loss. At this point, the relationship between the financial loss due to perishable foods and the costs of

The nitrite and nitrate in foodstuff and their associated harmful effects are of great concern for human health. More than 80% of human nitrate intake is attributed to the consumption of vegetables and fruits, and for this reason, more attention should be paid to the consumption of such foodstuffs and reduction of nitrate intake. Therefore, this study aimed to determine the variation of nitrate and

Recently, a hybrid breeding system was developed for diploid potato. We compared performance of diploid hybrids with commercially available tetraploid cultivars. Therefore, seedling tubers were produced from true hybrid seeds in field conditions. In the subsequent year, diploid hybrids grown from seedling tubers showed a yield potential comparable with commercial tetraploid cultivars: the highest yielding

Protection of the environment is one of the most important issues of politics in many countries. The food industry generates large amounts of waste, which can be further managed using biotechnological processes. The potato industry is one of the branches which generates a huge amount of waste that is burdensome for the environment. In the production process of potato starch, chips and alcohol, the

Potato (Solanum tuberosum L.) is considered to be one of the most prominent nongrain food crops throughout the world that can be regarded as most affordable and most accessible food to provide numerous health benefits. Potential role in improving human health is attributed to presence of wide range of phytonutrients in potatoes viz., polyphenols, anthocyanins, carotenoids, ascorbic acid and proteins

Fresh-cut potatoes are a good option for consumers who want a healthy diet but have limited time to prepare meals. However, the polyphenol oxidase enzyme released during cutting of potatoes reacts with phenolic compounds, causing browning. Cold storage can slow down this reaction to some extent, but it cannot prevent it. Enzymatic browning lowers polyphenol content and reduces consumer appreciation

The demand for processing potatoes has been increasing in Japan since the 1970s due to changes in eating habits from fresh potatoes to processed products. However, domestic supply of potatoes has not changed for the past five decades and the country is not self-sufficient in potato production. Understanding potato crop and soil-environmental yield limiting factors at growers’ management level is important

Potato starch was subjected to heat moisture treatment (HMT) in which the temperature and moisture content were varied. Two different levels of moisture content (30 and 35%) and temperature (100 and 120 °C) were selected. The crystallinity of the starches decreased after HMT, as confirmed by both X-ray diffraction (XRD) and Fourier Transform Infra-Red (FT-IR) analysis, and the XRD pattern of native

Potato common scab caused by bacterial pathogen Streptomyces scabies (Thaxt.) Waksman & Henrici is one of the most important diseases of potato (Solanum tuberosum L.) worldwide. Currently, the most effective and desirable method to control common scab is through the use of resistant cultivars. In order to decipher the genetic control of resistance to common scab disease in Canadian potato germplasm

Much of the nitrogen in crop fertiliser is degraded before acquisition. Technologies that stabilise urea-nitrogen minimise this. Degradation also specifically reduces the amount of ureic amine that many fertilisers initially contain, which is important because this nitrogen form has unique beneficial effects on plants. To investigate mechanisms whereby urea stabilisation increases potato tuber yield

Long-term storage of tubers in refrigerated and non-refrigerated storage induces sprouting and other degradative quality changes, thus making them unacceptable for consumption. There are already known effects of packaging materials on storability of fresh produce while optimization of package with respect to temperature for shelf life enhancement of tubers is still needed in the case of deficient storage

Developing cultivars that use nitrogen more efficiently is a sustainable strategy for reducing nitrogen use in crop production. To assess the genetic diversity for nitrogen use efficiency (NUE) and related traits in potato, a total of 97 (88 for the Western-European market and 9 Ethiopian) cultivars were evaluated at two nitrogen levels (40 kg/ha and 120 kg/ha) for 24 quantitative traits in Debre-Tabor

Potato tubermoth (PTM) Phthorimaea operculella (Lep.: Gelechiidae) is one of the pest species affecting Solanaceae worldwide. It can cause up to 80% of losses in potato open air crops as well as damage up to 100% of tubers during storage. Blattisocius (= Typhlodromus) mali (Acari: Blattisociidae), a predatory mite, was studied as a potential biological control agent of PTM. A prey acceptance bioassay

Potato is one the of world’s most important crops. It is grown primarily for human consumption but is also used to feed cattle and to produce alcohol and starch. In modern industry, potatoes are a major source of starch. Unpredictable growing conditions strongly influence the cultivation of starch potatoes. One of the best methods for dealing with unpredictable stresses, including those caused by climate

Green-sprouting potato seed tubers in light and elevated temperatures are vital for production in short-season climates. Using light-emitting diodes (LEDs) to inhibit sprout elongation during pre-sprouting may represent an energy-efficient alternative to traditional indoor light sources. Sprout growth inhibition and some photomorphogenic responses were therefore examined in potato cultivars exposed

RNA silencing is an important antiviral mechanism in plants. Small interfering RNAs (siRNA) or short hairpin RNAs (shRNA) are key stimulators for RNA silencing by acting as executors of viral restriction. Here, we have utilized RNAi technology to suppress potato virus X (PVX) in a transgenic potato cultivar. A stable shRNA of 107 bp directed against a conserved region in the coat protein (CP) gene
