Effect Of Sulphur And Silicon Fertilization On Growth And Yield Of Rice

Field experiment was conducted at Experimental Farm, Annamalai university, Annamalai Nagar,Tamil Nadu, India during 2008-2009 to study the effect of sulphur and silicon fertilization on growth and yield of rice. The treatments comprised four levels of sulphur (0, 15, 30 and 45 kg ha-1) and four levels of silicon (0, 40, 80 and 120 kg ha-1) and were laid out in factorial randomized block design with three replications. Among the different levels of sulphur and silicon, sulphur @ 45kg ha-1 and 120 kg Si ha-1 recorded higher values for growth (plant height, number of tillers plant-1 and dry matter production), yield attributing (number of panicles m-2 and number of grains panicle-1) characters and yield (grain and straw) of rice respectively. With regard to interaction effect, the above said treatment combination proved its superiority over other treatments by registering maximum growth, yield attributes and yield of rice
