Abstract

A field experiment was conducted during the kuruvai season (June – September) of 2023 at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Cuddalore district, Tamil Nadu, India, to characterize the influence of zinc, iron and silicon on growth dynamics and yield optimization of transplanted rice (Oryza sativa L.). The experiment was laid out in a randomized block design with three replications and ten treatments, combining various forms of zinc, iron, and silicon. The results revealed that growth and yield attributes of rice viz., plant height, leaf area index, dry matter production, productive tillers per square meter, number of grains per panicle, test weight and grain yield (5512 kg/ha) and straw yield (7726 kg/ha) were recorded significantly higher with application of RDF along with soil application of 25 kg of ZnSO4 and FeSO4 with 50 kg diatomaceous earth.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
