Abstract

Sidenuk rice is a superior rice variety produced by BATAN through a radiation mutation technique.             The new varieties that have been produced need to be supported by efforts to optimize production through fertilization technology. The purpose of this study was to determine the effect of organic fertilizer which can increase growth, production and reduce the use of urea fertilizer in lowland rice optimally. The study was conducted using a completely randomized design. Each was repeated 4 times so that the total experimental unit (pot) was 32 rice pots. The treatments include (1) Control (without urea fertilizer),              (2) Control (+) 100% urea, (3) 50% urea, (4) Local microorganisms (MOL), (5) Compost, (6) Biochar , (7) Azolla, (8) Mol + Compost + Biochar + Azola + SP 36 and KCl. The results showed that the highest grain weight was found in the 100% urea treatment, which was 43.97 g plant-1. MKBA treatment    (MOL fertilizer, compost, biochar, azolla) showed values that were not significantly different from 100% urea treatment. Organic fertilizer formula (MOL fertilizer, compost, biochar, azolla) can reduce the use of urea fertilizer by 50%.

Abstract

This study aimed to examine the growth response and yield of Mitani variety soybean plants after treating them with Rhizobium biofertilizer, Phosphate Solvent Microbes, and Azotobacter using gamma-ray irradiation technology. This research was conducted from January to May 2016 and used one-factor Randomized Block Design (RBD) with the several biofertilizer formulas treatments. The treatments level used were K0 = without fertilizer (control); K+ = 100% urea; Rhi = single strain Rhizobium; Rhi+MPF = Rhizobium Inoculant + Phosphate Solvent Microbes; and Rhi+MPF+AZ = Rhizobium + MPF + Azotobacter. Each application of biological fertilizer is mixed with 50% urea fertilizer. The data obtained were analyzed using the F-test (ANOVA) and continued with the Duncan Multiple Range Test (DMRT) at a confidence level α = 0.05. The results showed that the best plant height occurred in soybeans that were given rhizobium fertilizer and pophat solvent microorganisms. Meanwhile, the best average wet and dry weight of soybean plants (p<0.05) occurred in the 100% urea fertilizer treatment. Apart from that, the application of 100% urea fertilizer produces plants with higher water content compared to the biological fertilizer treatment. Another finding from this research is that the number of pods is not directly proportional to the weight of the root nodules. Generaly, it can be concluded that soybean plants respond more to urea fertilization than biological fertilizer.
