Title : EFFECT OF BIO-FERTILIZERS AND SILICON PRODUCTS IN INDUCING DEFENSE IN RICE AGAINST WHITE BACKED PLANTHOPPER

Abstract :

The field experiment was conducted during kharif, 2016 and kharif, 2017 to examine the effect of organic and inorganic products of silicon and bio fertilizers in inducing resistance against white backed plant hopper (WBPH) on rice. It was observed that silicon taken by rice plants in various treatments declined the population of WBPH as compared to control treatment. The treatment RHA+PF+KSB (T8) was the most effective treatment in reducing infestation followed by CaSiO3+PF+KSB (T5) and CaSiO3+KSB (T4), respectively. Silicon content was observed to be more in T5 followed by T8 and T4 treatments. The grain yield was highest in T5 (4475.83 kg/ha) followed by T8 (4173.33 kg/ha) and T4 (4103.17 kg/ha). The treatment T5 contained highest percentage of Si i.e., 7.71 % and 6.89 % at vegetative stage and reproductive stage, respectively. WBPH incidence at both the stages was significantly and negatively correlated to Si content (r= -0.714 and -0.770, respectively).
