Potential of upland rice yield based on tillers and leaf area on various organic matter as the observation variables

Abstract

The potential of upland rice production can be described through the parameters of the number of tillers and flag leaf area. This is supported on the optimal number of tillers forming the basis for grain formation, while the flag leaf area is an illustration of the potential assimilation that plants can produce. Provision of organic material in dry land is an alternative to increase the availability of ground water. The aim of this research was to study the relationship between variables, those were number of tillers, flag leaf area and grain production. The experimental method used was a Randomized Block Design (RBD) with 2 factors. Upland rice varieties were be the first factor, namely IPB 9G, IPB 8G, Sigambiri Merah, and Situ Patenggang. The second factor was organic materials: solid decanter, filter mud, oil palm empty fruit bunches, oil palm fibre, and cow manure. The results showed that upland rice had a greater number of tillers and wider leaves would produce higher production per plot. The provision of solid decanter could increase the number of tillers (51.56%), flag leaf area (35%), grain production per plot (55.12%) compared to the treatments without the provision of organic matter.
