Replication data for agronomic traits on reference set for fodder quality in Sorghum under drought

Data on agronomic traits for 142 entries from the trial conducted using Alpha Lattice design, with two replications under drought stress (irrigation withheld) and two under controlled (well irrigated) conditions in vertisols. The following data were recorded in field, days to fifty percent flowering, plant height, fresh biomass, dry biomass, and grain weight. The fodder quality assessment was performed in collaboration with ILRI-INDIA with the details mentioned below. The biomass was dried, chopped, and ground (to allow the powder to pass through 1mm sieve). Later the biomass was scanned in Near-Infrared Spectroscopy (NIRS) calibrated against conventional wet laboratory analyses and following parameters were recorded, nitrogen on dry matter basis (NDM-%), acid and neutral detergent fiber (ADF and NDF-%) acid detergent lignin (ADL-%), metabolizable energy (ME- MJ/kg DM) and in vitro organic matter digestibility (IVOMD). The NIRS instrument used was a FOSS Forage Analyzer 5000 (FOSS XDS RCA, Win ISI IV, Denmark) with software package Win ISI II. Experiment location on Google Map

本数据集涵盖142份试验材料的农艺性状数据，该试验采用Alpha格子设计（Alpha Lattice design），在变性土（vertisols）地块开展，设置干旱胁迫（停止灌溉）与正常灌溉（对照）两种处理，每种处理均设置2次重复。田间调查记录的性状包括：50%开花天数、株高、鲜生物量、干生物量及籽粒重量。本研究与国际家畜研究所印度中心（ILRI-INDIA）合作完成饲料品质分析，具体流程如下：将生物量样品进行干燥、切碎与研磨（使粉末可通过1mm孔径筛），随后采用近红外光谱技术（Near-Infrared Spectroscopy, NIRS）进行扫描，该光谱模型基于常规湿实验室分析进行校准，最终测得以下参数：干物质基含氮量（NDM-%）、酸性洗涤纤维与中性洗涤纤维（ADF、NDF-%）、酸性洗涤木质素（ADL-%）、代谢能（ME- MJ/kg DM）以及体外有机物消化率（IVOMD）。所用近红外光谱仪为FOSS饲料分析仪5000（FOSS XDS RCA, Win ISI IV, Denmark），配套软件为Win ISI II。试验地点信息可通过谷歌地图查询。
