Abstract

One of the alternatives to fulfil food needs, especially rice in Indonesia, is upland rice. Especially in the development of dry land and the development of cropping patterns on critical lands. Some of the obstacles that will be faced for upland rice cultivation are the risk of water stress, as well as the need for nutrients and soil organic matter. This research aims to see the effect of Application of Various Concentrations of Chitosan and Bacillus subtilis Biofertilisation on the Growth and Production of Upland Rice. The research was arranged based on a 2-factor factorial experiment with a Completely Randomised Block Design (CRBD) pattern, the first factor was Chitosan Application consisting of 3 levels, namely 0 (Control), 0.5, and 1.0 ml.L-1  The second factor is Baccilus subtilis  biofertilisation with 3 levels of 1, 1.5, and 2 ml.L-1. Parameters observed included plant height (cm), number of tillers, flag leaf area (cm2), number of panicles per clump, and number of seeds per clump. Observation results showed that the application of chitosan 1.0 ml.L-1 gave better results on plant height increase with an average of 79.33 cm, flag leaf area (average 31.67 cm2) and Baccilus subtilis 2 ml.L-1), while the application of Baccilus subtilis 1ml.L-1 gave the best results on Yield per clump with an average of
2273.2 per clump.
