6 extractive question-and-answer pairs built from Assessment of zinc sources and levels for urea coating to achieve higher productivity and soil fertility in spring maize (Zea mays) | The Indian Journal of Agricultural Sciences, published by epubs.icar.org.in. Source-evidenced topics include zinc sources, urea coating, productivity, soil fertility, spring maize, zea mays, zinc oxide, zinc sulphate. 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: 2 factual, 1 definition, 1 list, 1 relationship, 1 summary. 4 of the 6 pairs (66.7%) ask explanatory questions; the remaining 2 are factual or table-based questions. 100.00% of rows pass the corpus quality gate.
This dataset contains six question-and-answer pairs derived from a study conducted at the ICAR-Indian Institute of Maize Research in Ludhiana, Punjab during 2021 and 2022. The research focused on evaluating the efficacy of zinc oxide and zinc sulphate for urea coating to improve productivity, soil fertility, and enzymatic activities in spring maize (Zea mays). The experiment used a randomized block design with 11 treatments, including varying percentages of zinc applied through ZnO and ZnSO4. Key findings include the identification of optimal zinc levels for enhancing grain yield and soil health.
