This study investigated the effect of growing media composition on the growth and
productivity of Oryza sativa var. Inpago 7 cultivated in polybags at Sumedang, West Java,
Indonesia, for 126 days. A randomized block design was applied with nine combinations of
growing media. Each treatment consisted of five polybags and was replicated three times. Plant
height, number of leaves, and tillers were measured at 15, 30, and 45 days after transplanting to
observe the growth parameters. While, for estimation of productivity were recorded the weight
of dry grain harvest (DGH), the weight of dry milled grain (DMG), and the weight of 100 grains (g)
were recorded for each treatment for estimation of productivity. The results showed that the highest
number of panicles (24 panicles per plant), the weight of dry harvested grain (21.74 g per plant),
and weight of dry milled grain (17.83 g per plant) were obtained when cultivated with a growing
medium containing soil, biochar, synthetic fertilizer, urea and sprayed with nano-silica. The
growing media composition did not influence the weight of 100 grains because it is more influenced
by genetic characteristics. An appropriate combination of soil, biochar, synthetic fertilizer, urea,
and sprayed with nano-silica is recommended as a growing media for cultivating O. sativa L. var.
Inpago 7.
