Effect of Spraying Nano-Silicon in some Growth and Yield Traits For Two Oats Cultivars

Abstract

Abstract A field experiment was conducted in the winter of 2021-2022 in the Babel Governorate-Al-Shomali district, which is 68 km southeast of the city of Hilla, to examine the effect of spraying nano-silicone on some characteristics of vegetative growth and yield of two cultivars of oats. A two-factor experiment with three replicates was carried out using a randomized complete block design (RCBD). Both Shefaa and Carlop oats were used in the first factor, and in the second factor, nano-silicon was sprayed at 0, 1, and 2 ml L-1. The results showed that the Carlop cultivar significantly excelled and recorded the highest averages in plant height and flag leaf area when treated with nano-silicone sprays, as well as in the characteristics of growth, yield, and its components. When compared to the control treatment (spraying only distilled water), the cultivar Shifa produced higher averages of cuttings per square meter, panicles per square meter, and grains per hectare than its counterpart. Nano-silicone spraying at 2 ml L-1 resulted in considerably higher plant height, flag leaf area, chlorophyll content, number of tillers, number of panicles per m2, biological yield, and grains production (7.294 tons ha-1) compared to the other treatments. Because of the high averages obtained in most of the attributes investigated, it is clear that the interaction between the Shifa cultivar and sprays of nano silicon had a substantial effect.
