Abstract


Evaluation Of Morphological Characters and Production of Mutan Rice by Aplicating N And P
Different Fertilizer. Rice crop is the staple food for more than 1750 million people who inhabit the
countries of Asia and is a strategic political commodity, so that rice production in the country be
measured by the availability of food for Indonesia. Through the technique of irradiation to produce
mutants or mutated plants with properties expected after a series of testing, selection and
certification. This reaserch using Randomized Block Design with 2 factors, nitrogen (250, 300, 350
kg/ha) and phosphate (200, 250, 300 kg/ha). From the data analysis obtained that Nitrogen and
Phosfat fertilized treatment perform the significant effect to the plant height, number of tillers, the
maximum number of tillers, number of productive tillers panicle number, the number of panicle
branches, number of grains per panicle, 1000 grain weight, production per plant and production per
hectare. treatment did not significantly affect the parameter of seed germination,time germination,
he number of empty grains per panicle, the percentage of empty grains per panicle, length of
vegetative stage, length stadia generative, age of flowering , age of harvest and stem diameter.
Keywords : nitrogen, phosphate, mutan, rice
