The dataset contains 113 observations collected across four growing seasons (2020\\u20132023) from a replicated field experiment evaluating two irrigation configurations (1 vs. 2 drip tubes per row) and two harvest timings (EARLY and LATE). The experimental design followed a blocked structure with up to seven field blocks per year, enabling assessment of treatment effects across spatial replications and seasons. Each observation corresponds to a plot-level measurement and includes agronomic, pathological, and phytochemical variables. Agronomic metrics include fresh yield (kg/plant), dry yield (kg/plant), dry matter (%), cone color (1\\u201310 scale), and hop storage index (HSI). Brewing-relevant quality parameters include alpha acids (%), beta acids (%), and total oil content (mL/100 g). Plant health variables include incidence or severity ratings for hop-associated pathogens and viroids (Hop stunt viroid (HSVd), Apple mosaic virus (ApMV), American hop latent virus (AHLV), Hop latent viroid (HLV), and Hop mosaic virus (HMV)), recorded as plot-level measures. These data enable examination of potential interactions between irrigation regime, harvest timing, and pathogen pressure. A major component of the dataset consists of detailed volatile and terpene profiles (mg/kg), quantified for individual compounds commonly associated with hop aroma and brewing quality. Measured compounds include monoterpenes (e.g., \\u03b1-pinene, \\u03b2-pinene, myrcene, limonene), oxygenated monoterpenes (e.g., linalool, geraniol, nerol, terpinen-4-ol), esters (e.g., methyl geranate, geranyl acetate, geranyl isobutyrate), and sesquiterpenes and their oxides (e.g., \\u03b1-humulene, \\u03b2-caryophyllene, caryophyllene oxide, humulene epoxides I and II).</p>\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"downloadURL\": \"https://ndownloader.figshare.com/files/62453290\", \"format\": \"csv\", \"mediaType\": \"text/csv\", \"title\": \"Dataset.csv\"}], \"identifier\": \"10.15482/USDA.ADC/31403319.v1\", \"keyword\": [\"Humulus lupulus L.\", \"cone yield\", \"irrigation configuration\", \"virus incidence\"], \"license\": \"https://creativecommons.org/publicdomain/zero/1.0/\", \"modified\": \"2026-03-16\", \"programCode\": [\"005:040\"], \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Agricultural Research Service\"}, \"spatial\": \"{\\\"type\\\": \\\"Polygon\\\", \\\"coordinates\\\": [[[-120.63170251840982, 46.33611423598717], [-120.37421529279567, 46.33611423598717], [-120.37421529279567, 46.40544569533773], [-120.63170251840982, 46.40544569533773], [-120.63170251840982, 46.33611423598717]]]}\", \"temporal\": \"2019-04-01/2023-12-31\", \"title\": \"Data from: Stability of Hop Yield and Quality Factors in Response to Delivery of Irrigation and Harvest Timing\"}","source_transform":null,"status":"success"}
