A field experiment was conducted for three consecutive years at NAU, Navsari, during the year 2015-16, 2016-17and 2017-18 to study the effect of foliar spray of potassium silicate on growth and yield of paddy. Seven treatment of potassium silicate as a foliar spray (T1 : control, 0.T2 : 0.5 % potassium silicate at tillering and PI, T3 : 0.5 % potassium silicate at tillering, PI and grain formation stage, T4 : 1.0% potassium silicate at tillering and PI, T5 : 1.0% potassium silicate at tillering, PI and grain formation stage, T6 : 1.5 % potassium silicate at tillering and PI and T7 : 1.5 % potassium silicate at tillering, PI and grain formation stage) were tested in complete randomize design with four replication. The various growth and yield attributes viz., panicle length, panicle weight, number of grain per panicle and weight of grain per panicle, grain and straw yield, as well as gross return, net return and BC ratio were recorded significantly superior over control. under the foliar spray of potassium silicate @ 1.0 percent at tillering, panicle initiation and grain formation stage.
