A simple, accurate, and highly sensitive analytical method was developed for determining the paclobutrazol residue in potato and soil, the dynamics dissipation in soil. Extraction was carried out by low temperature partitioning and analyzed by ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). For a favor extraction yield, the parameters such as temperature and ...

introduction: frying phenomena occur during the immersion of the product in oil at a temperature of 150–200 ºc, where a simultaneous heat and mass transfer take place. this is the most popular thermal processes of potato cooking. this fast drying is critical to improve the mechanical and structural properties of the final product. these conditions lead to high heat transfer rates, rapid cooking...

Plant-mediated competition among insect herbivores occurs when one species induces changes in plant chemistry, nutrition, or morphology that render plants resistant to attack by others. We explored plant-mediated interspecific interactions between the potato leafhopper (Empoasca fabae) and the Colorado potato beetle (Leptinotarsa decemlineata), two important pests on potatoes. Leafhoppers colon...

Cultivating resistant varieties of potato is the most effective and environmentally safe method of protecting against pests and diseases that affect potato crops. Therefore, potato breeding is focused on developing more resistant varieties so that the use of plant health products can be reduced during the cultivation cycle. Resistance to late blight, viruses and nematodes is the most important ...

Bangbayang Village, Gekbrong District, Cianjur is an area with the main agricultural commodities being rice and purple sweet potato. This program aimed to increase knowledge ability of PKK group in Village processing potato into chips cakes. The method used this activity were analysis condition, training on food production packaging labels, as well evaluation attitudes. Based activities carried...

The effects of two mineral and two organic acids, four organic solvents (methanol, ethanol, 2-propano and acetone) and three inorganic metal salts in combination with temperature regimes 0 and 22C on the yield and resolubility of potato tuber proteins were studied. Using acids, the yield of precipitated protein ranged from 22.3% (citric acid, 0C) to 54.5% (acetic acid, 22C) of total protein; ho...
