Abstract

Rice cultivation activities can produce organic waste such as straw and husks which can be processed into solid organic fertilizer and liquid smoke. In addition to agricultural waste, organic material from livestock waste can also be used as organic fertilizer, one of which is cow urine which can be processed into cow biourine. This research aimed to determine the effect of organic fertilizer from straw, husk and cow biourine on the growth and production of rice. The research used factorial randomized block design (RAKF) with 2 factors. The first factor is solid organic fertilizer which consists of treatment without solid organic fertilizer, straw ash, and rice husk biochar. The second factor is liquid organic fertilizer which consists of treatment without liquid fertilizer, cow biourine, and husk liquid smoke. The observed parameters were plant height, number of tillers, leaf chlorophyll content, number of panicles, weight of 1000 seeds, and weight of grain per hectare. The results showed that there was an interaction between solid organic fertilizer (rice husk biochar and straw ash) and liquid organic fertilizer (husk liquid smoke and cow biourine) in increasing plant height, number of tillers, number of panicles, and yields. Separate treatment of solid organic fertilizer and liquid organic fertilizer affected the leaf chlorophyll content of rice plants. The application of rice husk biochar and cow biourine fertilizer resulted in the highest plant height, number of tillers, and number of panicles. In rice yields, the highest yields were found in rice husk biochar combined with cow biourine and husk biochar combined with husk liquid smoke.

Abstract

Tomato is the top priority in the development of horticultural crops. The obstacle which mostly encountered is Ralstonia solanacearum pathogen attack. Bacteriophage can cause bacterial lysis after they they develop themselves inside the bacteria. The specific of the bacteriophage can provide result quickly, accurately, and efficiently so that it can be used as an alternative to control bacterial wilt disease R. solanacearum environmentally friendly. This study aims to find out the effectiveness of bacteriophage to control the bacterial wilt disease R. solanacearum. The testing method are plaque assay, bacteriophage infections test in various dilutions, bacteriophage infection test in a liquid medium, and transmission electron microscopy test. In the greenhouse scale testing using a Completely Randomized Design (CRD) with 6 treatments and 4 replications. Quantitative data were analyzed using analysis of variance 5% error level and followed by least significant different test level of 5%. The results showed that bacteriophages can infect R. solanacearum. Bacteriophage can infect bacteria R. solanacearum indicated by the appearance of plaques in NA media, the declining value of absorbance spectophotometer, and can lyse bacterial cells from dilutions 10-1 to 10-9. The morphology of bacteriophages that infect R. solanacearum have hexagonal head structure and it have which is with a size of 200 nm. In the greenhouse scale showed that the symptoms of R. solanacearum appear at 29 days after inoculation. Application of bacteriophages can control R. solanacearum with lower percentage than the control treatment.
