Effect of soil and foliar application of zinc on growth, yield attributes and yield of rice (Oryza sativa L.)

Abstract
The experiment was performed in Randomized block design with 4 replications by taking 6 treatments viz., foliar application of zinc @ 250 ml ha-1, 500 ml ha-1, 750 ml ha-1, combination of basal application of zinc sulphate @ 10 kg ha-1 + foliar application of zinc @ 750 ml ha-1 or alone basal application of zinc sulphate @ 10 kg ha-1 and Untreated control. Maximum growth parameters viz., number of leaves plant-1, number of tillers plant-1, dry matter accumulation, leaf area index and yield attributes viz., number of effective tillers m-2, filled grains panicle-1, panicle weight, panicle length, number of filled grain per panicle, grain yield and straw yield was noted with foliar application of zinc @ 750 ml ha-1 which was comparable with foliar application of zinc @ 500 or 250 ml ha-1 or combination of basal application of zinc sulphate @ 10 kg ha-1 + foliar application of zinc @ 750 ml ha-1 and alone basal application.
