Abstract

Utilization of farm wastes in order to realize the concept of integrated farming is a sustainable agriculture community service program in cooperation with two partners, namely : ( 1 ) quail - catfish Breeders 'Agribird', and ( 2 ) dairy farms and agricultural businesses " Andini Mulyo ". This service activities conducted through outreach / awareness, mentoring and manufacture of demonstration plots. Preparation of demonstration plots to make an example of earthworm cultivation ( vermikultur ) and the making of silage. Testing vermicompost and organic fertilizer from cow dung to plant corn and kale using plots measuring 50 x 9 meters, divided into 3 blocks, each 3 x 50 meters. Outcome in the form of products include : Biomass earthworm number 5 Kg / month ; Vermicompost 50 Kg ; Silage, 300 Kg once manufacture ; and quality organic fertilizer from cow dung, 600 kg / process. Outcome in the form of a test product to the plant : the use of manure, vermicompost fertilizer in Litosol very real increase maize crop which includes fresh weight of corn stover, corn stover dry weight and dry weight of seed corn ; the use of manure and fertilizer plants in the ground grumosol not significantly different with kale stover fresh weight, while the use of vermicompost highly significant increase stover fresh weight of spinach.

Abstract

Rice production in Indonesia can not cover the national needs. The low productivity caused by the decline in soil fertility. One way to increase the phosphorus content in the soil is to provide natural phosphate fertilizer and Azolla inoculum. This study was conducted to determine the proper dose of Azolla inoculum and rock phosphate to increase the availability of phosphate and increase the yield of rice plants on land Alfisol. This study uses the two-factor factorial CRD comparative treatment of manure and fertilizer N, P, K. Analysis of the observed data using analysis of variance at 5% level and if there is a significant difference effect followed by DMRT 5% level to compare between treatments. The results showed that treatment of Azolla inoculum and phosphate can increase the availability of phosphate in the Alfisol soil and can increase rice yield. On the parameters available P showed the highest results in the treatment of Azolla 2.5 tons / ha without natural phosphate and Azolla 5 tons / ha of natural phosphate 350 kg / ha which is 10.81 ppm. In addition, administration of Azolla inoculum and phosphate levels give rise to CEC, organic matter, total N in the soil and soil pH.
