Effect of zinc and silicon nanoparticles on yield, quality and economics of lowland paddy

An investigation to know the effect of nano zinc and silicon on quality yield rice was conducted at AHRS, Bavikere, KSNUAHS, Shivamogga. The experiment consisted 12 treatments replicated thrice laid in completely randomized block design. different treatment combinations seed silicon, foliar spray nanoparticles were compared with conventional sources control. Application both (T6) form as @ 40 ppm each DAT registered significantly higher no. productive tillers (18.72), protein content (11.41 %), starch (75.70 %) grain (6034 kg/ha), straw (6693 kg/ha) economic net returns (98631 Rs ha-1), particles alone showed next best results.
