<![CDATA[The increase in onion production on red-yellow podzolic soils is faced with physical and chemical properties that are not good for plant growth so that efforts are needed to improve the land by applying a combination of kirinyu green manure and incubation duration. This study aims to determine the best dose and duration of incubation of kirinyu fertilizer against the growth and yield of onions on red-yellow podsilok soils. The research was carried out on the experimental land of the Faculty of Agriculture. The research time is from April 12 to May 27, 2020. The method used in the study was a Complete Randomized Design (RAL) by giving a combination of doses and incubation time of kirinyu green fertilizer which was repeated 3 times, and consisted of 3 sample plants so that the sample plants were entirely 81 plants. . The treatment in question is k1 (375 g / polybag of kirinyu green manure incubated for 2 weeks); k2 (375 g/polybag of kirinyu green manure incubated for 3 weeks); k3 (375 g/polybag of kirinyu green manure incubated 4 weeks); k4 (750 g/polybag of kirinyu green manure incubated for 2 weeks); k5 (750 g/polybag of kirinyu green manure incubated for 3 weeks); k6 (750 g/polybag of kirinyu green manure incubated for 4 weeks); k7 (1125 g/polybag of kirinyu green manure incubated for 2 weeks); k8 (1125 g/polybag of kirinyu green manure incubated for 3 weeks); k9 (1125 g/polybag of kirinyu green fertilizer incubated for 4 weeks The results showed that the combination of dose and duration of incubation of kirinyu green fertilizer had an unreal influence on all observation variables, namely plant height, number of leaves, number of saplings, root volume, and fresh weight of plants.]]>
