Title
Effect of silicon fertilizer application on dry matter remobilization and grain yield of native and improved rice genotypes
Authors
Abstract
In order to investigate the effect of silicon fertilizer application on dry matter remobilization and grain yield
of rice genotypes, a field experiment was carried out at Rice Research Station, College of Agriculture,
University of Guilan in 2013 in a Split plot lay out in a randomized complete block design with three
replications and six rice genotypes. The treatments consisted of zero, 100 and 200 kg.ha-1 silicon and three
native rice genotypes Hashemi, Ali Kazemi and Sang Jo, and three promising lines 831, 841 and 416,
respectively. Sampling for dry matter remobilization was conducted in two phases, anthesis and maturity.
Results showed that the highest rate of remobilization of the Ali Kazemi (520 g.m-2) and the lowest amount
for 841(87 g.m-2) indicating a greater contribution of remobilization. Maximum and minimum remobilization
efficiency was also related to Ali kazemi and 841(48% and 28%, respectively). According to the results of
this experiment it seems that silicon fertilizer may enhance remobilization and grain yield in improved rice
varieties due to the increase in total dry matter, while the native varieties with no silicon fertilizer, had the
highest rate of remobilization.
