Abstract

Experiment was carried out at Nattapatti village, Madurai district to evaluate the effects of silicon (Si) fertilization on green gram plants for reducing damage of Empoasca kerri. Treatments comprised two types of Si sources such as silicic acid @ 0.1 and 0.2% and potassium silicate @ 0.5 and 1.0% with gibberellic acid @ 50 and 100 ppm (foliar spraying). The population density of E. kerri was observed weekly during the growth season. The treatment with potassium silicate 1.0% @ 10 DAS & 20 DAS with gibberellic acid 100 ppm @ 30 DAS and 40 DAS significantly decreased the population of E. kerri.
