Dataset for: Organic agriculture trial in the locality of La Soledad, Chugay district, La Libertad - Peru (First season 2022-2023)

An experimental potato trial based on organic agriculture in the 2022-23 season was conducted in a total area of 987 m2 with the support of the "Asociación de Productores Agropecuarios y Semilleristas La Poderosa" of the locality of La Soledad, Chugay district, province of Sánchez Carrión, La Libertad. For this trial, the improved potato variety INIA-325 Poderosa was used with a split-plit plot design considering three factors: crop intercropping (intercropping with faba bean, variety Señorita and no-intercropping), use of a decision support system for fungicide application or “Juego de Ruedas” (Disc and no-disc) and the application of organic amendments (1, 2 and 4 t ha-1 of poultry manure). The combination of these factors generated a total of 12 treatments; and an additional control treatment (conventional practices in the study zone). In adition, 4 replicates were established, with a total of 52 plots of 3x4 m2 each (distance between plant and furrow of 0.3 m and 1 m, respectively). The variables evaluated were: emergence (%), canopy cover (%), chlorophyll content (SPAD units), plant height (cm), fresh tuber yield (t ha-1), cost-benefit ratio and carbon footprint (kg CO2e Total) at different times during the vegetative period of the crop.

本试验为2022-2023季基于有机农业的马铃薯田间试验，试验地块总面积987平方米，由位于拉利伯塔德省桑切斯卡列翁区丘盖伊镇拉索莱达地区的"Asociación de Productores Agropecuarios y Semilleristas La Poderosa"（农牧生产者与种子商联盟La Poderosa）支持开展。本次试验采用改良马铃薯品种INIA-325 Poderosa，采用裂裂区试验设计，设置3个试验因子：其一为作物间作模式，设置与品种为Señorita的蚕豆间作、不间作两个亚处理；其二为杀菌剂施用决策支持系统或"Juego de Ruedas"方案，分为圆盘式与非圆盘式两类亚处理；其三为有机改良剂施用水平，设置每公顷施加1、2、4吨家禽粪便三个亚处理。上述因子组合共产生12个处理组，另设1个对照处理（采用研究区域常规农事操作）。试验设置4次重复，总计52个试验小区，每个小区面积为3×4平方米，株距0.3米，垄沟间距1米。试验测定的指标包括：出苗率（%）、冠层覆盖率（%）、叶绿素含量（SPAD单位）、株高（cm）、块茎鲜产量（吨·公顷⁻¹）、成本效益比，以及作物营养生长期不同时段的总碳足迹（千克CO₂当量）。
