16 extractive question-and-answer pairs built from Microsoft Word - Details of varieties released, published by agritech.tnau.ac.in. The source is a 2-page publication. Source-evidenced topics include tnau, coimbatore, forage crop varieties, hybrids, cereal fodders, grasses, legume fodders, tree fodders. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. Question types in the export: 10 factual, 6 summary. 6 of the 16 pairs (37.5%) ask explanatory questions; the remaining 10 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains extractive question-and-answer pairs about forage crop varieties released by Tamil Nadu Agricultural University (TNAU) between 1980 and 2014. The data includes details on cereal fodders, grasses, legume fodders, and tree fodders, highlighting their special features such as drought tolerance, high yield, and palatability. Each record cites the source document, allowing verification of the claims. The dataset is based on a 2-page publication from agritech.tnau.ac.in.
