ABSTRACT

A Field experiment was conducted at Indian Institute of Rice Research (IIRR), Hyderabad during kharif 2014 and kharif 2015 to study the influence of silicon solubilizers on growth and yield of eight rice genotypes. The treatments comprised of control (T0), silixol @ 0.2% (T1) and Imidazole @0.05% (T2) and sprayed at tillering stage. The experiment was laid out in split plot design, replicated thrice. Growth and physiological traits viz., plant height, tiller number, leaf area and dry matter accumulation measured at different intervals and grain yield significantly increased under silicon solubilizer treatments compared to control.

KEY WORDS: Rice, silicon, solubilizer, genotypes, yield
