Abstract

Farmers and French fry producers have stated that each year, various factors impact the frying quality of potato tubers. As a result, a trial was designed to study the frying color development of the cultivar Innovator grown under different conditions (location, nitrogen fertilization, and harvest date) and stored at 6.5°C and 7.5°C. The samples were evaluated monthly from December to March. A multiple regression model was created using all the samples from the two trial years, explaining > 85 % of the differences in frying color. Additionally, models for both the years and every sampling month were calculated. These multiple regression models helped measure the impact of the variables and their consistency. The results revealed a significant impact of the climatic water balance in the latter part of June, which explained differences between years and locations. Other factors determining frying color were the harvest date, storage duration, and storage temperature. No effect of the location or the tested nitrogen fertilization rates could be found.

农艺参数和贮藏参数对马铃薯油炸色泽的影响

农民和炸薯条生产商表示，每年都有各种因素影响马铃薯块茎的油炸质量。为此，设计了一项试验，研究了不同条件（地点、施氮量和采收日期）和6.5°C和7.5°C贮藏条件下Innovator品种的油炸色发育。从12月到次年3月，每个月对样本进行评估。使用两个试验年份的所有样本创建了一个多元回归模型，解释了>； 85 %的油炸颜色差异。此外，还计算了年份和每个采样月的模型。这些多元回归模型有助于测量变量的影响及其一致性。结果表明，6月下旬气候水平衡的影响显著，这解释了年份和地点之间的差异。其他决定油炸颜色的因素是收获日期、储存时间和储存温度。试验地点和施氮量对土壤肥力没有影响。

期刊介绍： The European Journal of Agronomy, the official journal of the European Society for Agronomy, publishes original research papers reporting experimental and theoretical contributions to field-based agronomy and crop science. The journal will consider research at the field level for agricultural, horticultural and tree crops, that uses comprehensive and explanatory approaches. The EJA covers the following topics: crop physiology crop production and management including irrigation, fertilization and soil management agroclimatology and modelling plant-soil relationships crop quality and post-harvest physiology farming and cropping systems agroecosystems and the environment crop-weed interactions and management organic farming horticultural crops papers from the European Society for Agronomy bi-annual meetings In determining the suitability of submitted articles for publication, particular scrutiny is placed on the degree of novelty and significance of the research and the extent to which it adds to existing knowledge in agronomy.
