Abstract
Rice (Oryzae sativa L.) is the staple food crop of over half of the worldâs population and also widely cultivated across the world, making it possibly the most valuable plant on earth. Silicon is essential element it can defense against biotic and abiotic stress in many crops and their diseases. In the present study Silixol @ 0.3%, 0.6%, 0.9% and 1.2% were evaluated against Pyricularia grisea in different period of incubation for the assessment of mycelial growth and Sporulation in Potato Dextrose agar medium. Among five concentrations Silixol @ 0.6% showed inhibition of mycelial growth over control. Silixol @ 0.6% were applied to nine genotypes. Treatments with (T2 irrigated+0.6 Silixol) and (T3 drought+0.6 Silixol) enhanced growth parameters and Morph physiological and Yield Parameters under Drought stress however (T2 irrigated+0.6 Silixol) recorded minimum disease incidence and it can be correlated with weather parameters.
