Rice (Oryza sativa L.) is the second most widely consumed crop in the country after wheat. Foliar application is an effective method for enhancing the growth and yield of agricultural plants,. To investigate the effect of foliar application of potassium silicate and seaweed extract on yield, yield components, and the concentration of silicon and potassium in rice, a factorial experiment was conducted in a randomized complete block design (RCBD) with three replications under field conditions. The experimental treatments included foliar application of potassium silicate at three levels (0, 1, and 2 lit ha-1) during the maximum tillering stage and the early panicle initiation stage, as well as foliar application of seaweed extract at three levels (0, 1, and 2 lit ha-1) during the seedling establishment, rooting, and beginning of tillering stages. Based on the results of variance analysis, the effect of treatments on all evaluated traits, except for plant height, panicle length, stem length, and the number of unfilled grains, was significant. The results indicated that the highest paddy yield, with an average of 5,352.98 kg ha-1, the highest total number of grains per panicle, with an average of 112.45, and the highest 1000 grain weight, with an average of 22.65 gr, were observed in the treatment with 2 lit ha-1of potassium silicate and seaweed extract. The lowest values for these traits were recorded in the control treatment. With increasing treatment concentrations, the potassium and silicon content in rice grains increased. The highest levels were obtained from the foliar application of 2 lit ha-1 of potassium silicate and seaweed extract, with an average of 0.533 mg/kg for potassium and 1.30% for silicon. The results indicate that the combined application of potassium silicate and seaweed extract has a more favorable effect on growth parameters. Overall, foliar application of potassium silicate and seaweed extract is recommended to achieve maximum yield and enhance potassium and silicon concentrations in rice plants.
