Abstract
This study was conducted to determine the effect of different planting distance and fertilizer application in the growth and yield of aromatic rice. three different planting distance: A1 (20 x 20cm), A2 (20 x 25cm) and A3 (25 x 25 cm) and three different fertilizer application: (B1 (120-60-60), B2 ( 10 tons/ha of organic), B3 (60-15-15+ tons/ha of organic) were evaluated, following Factorial in Randomized Complete Block Design (RCBD) with three replications.
Results revealed that there was highly significant difference among fertilizer application on panicle lennth, filled grain per panicle, weight of 1000 grain and grain yield per tons/ha. On the other hand, there wre significant difference among plant spacing on percent head rice recovery, productive tiller. No significant difference was observed on the interaction between plant spacing and fertilizer application.
In this study of Aromatic rice (CL1) applied by 25cm x 25 cm plant spacing and Recommended Rate of Inorganic Fertilizer consistently produced high percentage in weight of 1000 seeds, computed grain per hectare and in milling recovery data show this treatment combination have better result among nine treatment combination. This treatment can be applied (as it is more practical) to improve the yield of CL1 which is promising while awaiting release.
