Reaction of rice (Oryza Sativa) cultivars to silica and potassium fertilizer

In study The effects of different amounts of silica and potassium fertilizers on yield rice varieties, a factorial experiment in rice-based design Randomized complete block with three replicates in crop year 2010 the farm was located in Astaneh Ashrafiyeh. It included three levels silica and potassium, and the figure that the first factor in the two level 0 and 375 kg per hectare, the second factor in the three levels of 0, 175 and 350 kg per hectare and the third factor in the two digit level of Hashemi and Ali Kazemi was. Results showed that the fertilizer silica fertile tillers in both cultivars decreased and increased the number of fertile tillers. Increase the number of fertile tillers increased the yield. Fused with fertilizer and grain number per panicle fertilizer potassium, silica and minor increase in consumption of fertilizers increased grain and straw yield and various amounts of silica and potassium, a highly significant difference in both there was a figure. Silica and potassium Chloror fertilizers taking the maxi and min grain yield in the Hashemi with 4647 and 3341 kg per hectare and the max and min grain yield with Ali Kazemi, respectively 4050 and 3110 kg per hectare respectively. Cultivars in all traits were significant differences with each other.
