Abstract
The objective of this study was to analyse the effects of drought stress and silica application on black rice (Oryza sativa L.) growth and yield. The first factor was drought stress (P0 = control, P1 = drought stress during tillering stage (25-40 days after planting/ DAP), P2 = drought stress during flowering stage (50-65 DAP), P3 = drought stress during seed formation (65-80 DAP)). The second factor was the application of silica fertiliser (S0 = without silica, S1 = with silica). The data obtained were analysed by analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) 5%. The observed variables showed that drought stress had a significant effect on plant height, total number of shoots, number of productive shoots, number of grains per panicle, weight of grains and weight of grains per panicle. Silica application increased plant height, total number of shoots, number of productive shoots, weight of grains, and weight of grains per panicle.
