The Improvement of Red Rice Paddy Growth by Population Arrangement and Organic Fertilizer in Dry Land

Abstract

The requirement of red rice always increases periodically but the availability of its at wetland has been recessive by land use change and rice cultivation in general. Alternative solution is directed to dry land and be the opportunity of red rice paddy area expansion that based on appropriate technology.  In fact, red rice paddy has cultivated on the dry land in scatter plot system and the production is relatively low (1.5-2.5 ton.ha^-1). Scatter plot system causes the high competition between plants and gives directly impact on production. There are many wide areas of dry land in Indonesia and still not productive, so the good cultivation method has to be created through the arrangement of plant population and organic fertilizer as good agricultural practices manifestation. The goal of research is to increase production of red rice with high quality continuously and to improve the potency of dry land and also to increase the capability of dry land as a planting area.  The research is conducted by experiment method by Randomized Completed Bock Design with plant population (scatter plot, 2, 4, 6 seeds per hole) as first factor and dose of manure (10, 3, 5, 7 ton.ha^-1) as the second factor (there are 16 combination treatments). Each of combination treatments is replicated three times. The result shows that combinations of 6 seeds per hole with 3 ton.ha^-1 of manure give the highest amount of productive tiller and dry weight of grain (1.3 gram per clump and it is equal with 3.25 ton.ha^-1).
