Abstract

Interaction of microbes with human living in the nature are able to seen from their capabilitiesimproving the environmental by composting waste of agriculture to become organic fertilizer. In thecontrary, the epidemic and infectious phatogens are also its contribution. In agriculture sector, the livingof microbes has been explored to keep the soil fertile, and to improve growth and plant production.The symbiosis of Rhizobium bacteria with the specific host plant from legumes is able to run because ofboth side giving a signal, where host plant give an organic molecoles called inducer. From the bacteriaside, also give an organic materials called nod factor. The step of nitrogen fixation mechanism can bedescribed from infection of root legume as the first step, followed by the nitrogen fixation by thebacteroid and synthesis of the nitrogen organic by host plant as the last step. These natural processesinspire finding and development of the ecologically organic fertilizer technology.

Abstract

Pathway analysis is the further test after correlation test. Correlation between characters of plantwill be change in one field condition to other condition field. Correlation between characters on organicor semi-organic farming system still studied limitedly included in our project about organic/semi-organicfarming. Agrisimba is the probiotic microbes, one of technology for decomposing straw rapidly. Thestudy was done on November 2011 – March 2012 in Sawah Kidul Village, Pasawahan – PurwakartaDistrict with “farmer participatory on farm research method”. Inpari 13 was the indicator variety andAgrisimba was the treatment to decomposing straw rapidly in rice field to support organic farmingsystem as this topic study. Correlation analysis showed that plant high and value of pithy grain/tasselhave level of closeness significantly with yield character. On further test analysis showed that plant highwas the highest value of direct influence and 100 grain weight was highest value of indirect influence foryield character.

Abstract

Field experiment was conducted at Antapan village, Baturiti, Tabanan Regency. The experimentaim was to study the optimals of Shisako organic fertilizer dosage for growth and yield of potato. Theexperiment utilized Randomized Complete Design, one factor with six rated of Shisako organic fertilizerdosage treatments. The dosage treatments were: D0 = 0 ton/ha, D1 = 2,5 ton/ha, D2 = 5 ton/ha, D3 =7,5 ton/ha, D4 = 10 ton/ha and D5 = 12,5 ton/ha. The results showed that Shisako organic fertilizerdosage was highly significantly different to plant height, leaf number, leaf area index, tubers number perhill, tuber fresh weight per hill and fresh tubers weight per hectare than control. The optimum of Shisakofertilizer dosage treatment for microtuber Granola of potato cultivars from this research was found at6,08 ton/ha with the maximum wet weight tubers was 5,13 ton/ha.
