Interactive effect of silicon, chemical fertilizer and cow manure on growth and yield of glutinous rice, RD6 variety planted in a sandy soil

Abstract

The study examined the combined effects of silicon, chemical fertilizer, and cow manure on the development and productivity of the RD6 variety of glutinous rice cultivated on sandy soil. The investigation was conducted in a pot. The experimental design was a randomized complete design with 4 replications of 2 factors: factor 1 was the type of fertilizer used, which included chemical fertilizer, cow manure, and chemical fertilizer combined with cow manure, and factor 2 was the variation in silicon rates. There were 4 different amounts of silicon: 0, 100, 200, and 300 mg/kg. The results showed that using chemical fertilizer coupled with cow manure and applying 200 or 300 mg /kg improved rice growth, yield, and quality. Furthermore, the rate of silicon application increased the overall silicon contents in plants. This finding suggested that adequate fertilizer management might improve rice yields grown on sandy soil.
