In crop production, it is essential to know the soil characteristics, water requirement, and crop suitability in order to have favorable plant growth and yield. This study was conducted to determine the growth and yield performance of aromatic rice grown in different soil textures and water levels. The experiment was laid out in a 2 x 3 split-plot, Completely Randomized Design (CRD) with three replications. Four containers per treatment (21.5cm and a height of 23cm pail size) were used, each filled with 10 kg soil under saturated conditions. The different soil textures (S1- Clay Loam, S2- Clay) were designated as the main plots, and various water levels (W1- 1.5cm, W2- 3.0cm, W3- 5.0 cm) were considered as the subplots. The results revealed that rice grown in clay loam soil (S1) were taller, had broader 1 leaf area index, produced flower early, and have more number of tillers hill- (21.11). Likewise, longer panicle length (21.79cm), highest percent filled grains (82%), and 1 1 total grain yield (55g hill- ) equivalent to 6.11 t ha- were obtained from plants grown in clay loam soil. Plants grown in 3.0cm water levels produced more productive 1 tillers hill- (21.83), the highest number of filled grains (138), and highest grain yield 1 1 at 54.35g hill- or equivalent to 5.99 t ha- .
