Abstract:
The study aims to determine the growth and development of rice plants (Oryza sativa L.) through several treatments of the highest high water table on soil inseptisol. Research using Complete Randomized Design (CRD) with six treatments namely: (1) A = High of water level 5 cm above the soil surface, (2) B = High of water level parallel to the ground surface, (3) C = High of water level 5 cm below the soil surface, (4) D = High of water level 10 cm below the soil surface, (5) E = High of water level 15 cm below the soil surface, (6) F = High of water level 20 cm below the surface ground. Each treatment was repeated 3 times, so there are 18 experimental units. To find out treatment, test use DNMRT at 5% level. The results showed a high level of ground water level applications -15 cm can increase the rate of plant growth, net assimilation rate, plant dry weight, total number of tillers and the percentage of productive tillers. Highest percentage of productive tillers results obtained in the treatment of high ground water level is 89.33% -15 cm (29 stems).
