Abstract

A pot experiment was conducted to determine survival, growth and yield responses of several rice cultivars under different depths of deposited volcanicejecta.

Significant varietal differences were obtained on agronomic characters and yield components, such as plant height, days to flowering, root biomass, root to shoot ratio, harvest index, 100-grain weight, number of productive tillers per plant, number of unproductive tillers per plant, spikelet fertility and grain yield. Grain yield was highly correlated with harvest index, spikelet fertility and 100-grain weight. Harvest index was high correlated with spikelet fertility and negatively correlated with number of productive tillers.

Significant effect of volcanic ejecta were obtained on plant height, number of productive tillers per plant, 100-grain weight, grain yield, spikelet fertility, root biomass, root to shoot ration and harvest index. Number of productive tillers and harvest index were found to be negatively correlated to depth of volcanic ejecta. Root to shoot ratio was positively correlated to depth of volcanic ejecta. Highest 100-grain weight, number of productive tillers, grain yield, plant height number of days to flowering, root biomass, root to shoot ratio and harvest index were obtained from four inches volcanic ejecta plus six inches paddy soil.

The varieties which can be recommended under different depths of volcanic ejecta were Sinandomeng, Borong, Pinili, Nagdami, Bengawan, Puro-puro and Binangan.
