Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...

Potato Genebank of the Universidad Austral de Chile (UACh) is an important gene bank in Chile. The accessions collected all over the country possess high genetic diversity, present interesting agronomic and cooking traits, and show resistance to biotic and abiotic stress. A particularly interesting subgroup of the gene bank includes the accessions collected in the South of Chile, the Chilota Po...

The field experiments were conducted during two consecutive rabi seasons (October – February) 2019–20 and 2020–21 at ICAR-Central Potato Research Institute Regional Station, Gwalior, Madhya Pradesh, India located in west central plains of India. Highest emergence potato plants was recorded with the planting 40 g whole tubers. Growth attributes viz. plant height (58.6 cm) number compound leaves ...

This study investigated the mechanisms of seed potato management by potato growers of Freydunshahr County in Isfahan province. Survey research method was used in this study. A sample of 250 potato growers (N=725) was selected for data collection. Stratified random sampling method was used. The research instrument was a questionnaire that was validated for face validity by a panel of faculty mem...

The need for clarity regarding the sieving characteristics of potato-soil mixture, as provided by swing separating sieve a potato digger, well derived problems low transportation efficiency, high damage rate and unearthing rate, are main reasons this study. Dynamic tracking technology is proposed to collect motion state potatoes, during process soil separation. Considering conveying speed, indi...

The nutrient and anti nutrient composition of some standardized sweet potato dishes in Kwara state was determined using official methods of analysis. The indigenous sweet potato dishes analysed included pounded sweet potato/yam; sweet potato leaf soup; boiled sweet potato; fried sweet potatoes and sweet potato/ beans pottage. There were significant differences (p < 0.05) for moisture content wh...

A recently synthesized kairomone blend, based on the volatiles produced by potato (Solanum spp.) plants, has been demonstrated to be attractive to both adult and larval stages of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). It was subsequently formulated in a viscous inert carrier for Þeld applications and showed potential for aggregating beetles in t...

This study was performed to investigate the inhibitory effect of green onion produced in Korea on the growth of A. parasiticus, a toxigenic strain. The effect was studied using different concentrations of freeze-dried green onion in solid culture with potato-dextrose agar (PDA) or in liquid culture with yeast-extract sucrose (YES) broth at 25°C for 15 days. The addition of green onion to the me...

Survival and fecundity of Colorado potato beetle adults, Leptinotarsa decemlineata (Say), that had or had not fed previously on non-transgenic potato before exposure to transgenic potato containing the Bacillus thuringiensis subsp. tenebrionis Cry3A toxin (Bt) was investigated. In the laboratory, < 5% of first-generation adults survived after two weeks when restricted to Bt foliage since eclosi...
