Results And Quality Of Various Rice Varieties That Applied Of Fixator Bacteria As A Source Of Nitrogen

Abstract This study aimed to determine the effect of various varieties and packages of fertilization inorganic and biological either singly or interactions of the results and the carbohydrate and protein content of grain. The study was conducted from March to October 2012 at the screen house Faculty of Agriculture University of Hasanuddin. The design used was a randomized block design group RAK two-factor factorial. The first factor is the rice variety consisted of four types namely Pandan Putri varieties Invari Sidenuk Ciliwung and Ciherang. The second factor is five packets fertilization namely 5.0 L Azospirillum sp. dose recommendation of urea 2.5 L Azotobacter sp.12 dose of recommendation of urea 5.0 L Azotobacter sp. 5.0 L Azotobacter sp. And dose recommendation of urea 2.5 L Azospirillum sp. 2.5 L Azotobacter sp .. The results showed that the varieties of Invari Sidenuk gave the highest grain yield per panicle is 71.64 g followed by Ciherang 65.31 g Ciliwung varieties 65.25 g and the last varieties of Pandan Putri amount of 60.99 g. Ciherang varities that given 12 dose of recommendation of urea 5.0 L Azotobacter sp. resulted in the highest of carbohydrate content of 72.59 and the highest grain protein content was obtained from the treatment of Pandan Putri varieties inoculated with 5.0 L Azospirillum sp . It was concluded that the combination of a half dose of recommendation of urea and biological fertilizer Azotobacter sp. increased rice yield and grain carbohydrates and grain protein is given a 5.0 L Azospirillum sp. at the study site.
