10 extractive question-and-answer pairs built from Anti-oxidative enzymes in relation to iron toxicity caused by differential soil ironcontent in winter rice (Oryza sativa) of Assam, India | The Indian Journal of Agricultural Sciences, published by epubs.icar.org.in. Source-evidenced topics include anti-oxidative enzymes, iron toxicity, soil iron content, winter rice, oryza sativa, assam, india, peroxidase (pod). 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: 8 factual, 2 list. 2 of the 10 pairs (20.0%) ask explanatory questions; the remaining 8 are factual or table-based questions. 90.00% of rows pass the corpus quality gate.
This dataset contains 10 extractive question-and-answer pairs derived from a study on anti-oxidative enzymes and iron toxicity in winter rice varieties in Assam, India. The research explores the effects of differential soil iron content on rice plants, focusing on enzyme activity and iron fertilization outcomes. It also includes metadata about The Indian Journal of Agricultural Sciences, where the study was published. The dataset highlights specific findings, such as the response of certain rice varieties to iron fertilization and the activities of enzymes like superoxide dismutase (SOD) during grain filling stages.

| What was the rate of iron fertilizer applied to the soil in the pot experiment? | 1 L of 50 ppm FeSO4.7H2O to 6 kg soil | A study was conducted at Assam Agricultural University, Jorhat, Assam to know the effect of differential soil iron content on plant (leaves and grain) iron content together with the activities of some anti-oxidative enzymes, viz. peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) in a few popular rice varieties of Assam. The result of the pot experiment under rain protected condition revealed that application of iron fertilizer to soil (1 L of 50 ppm FeSO4.7H2O to 6 kg soil) of initial soil iron content 159.40 mg/kg before planting led to increase in leaf iron content from 39.16 mg/100 g (control) to 45.36 mg/100 g (treated) at harvesting stage. no iron toxicity symptoms were observed which might be due to higher activities of CAT at maximum tillering stage and SOD at grain filling stage. | 454 | factual | 0.570 | https://epubs.icar.org.in/index.php/IJAgS/article/view/140840 | The result of the pot experiment under rain protected condition revealed that application of iron fertilizer to soil (1 L of 50 ppm FeSO4.7H2O to 6 kg soil) of initial soil iron content 159.40 mg/kg before planting led to increase in leaf iron content from 39.16 mg/100 g (control) to 45.36 mg/100 g (treated) at harvesting stage. | ||||
