Abstract: Enhancement of productivity of potato plants grown on poor-P soil such as Inceptisols due to application of arbuscular mycorrhizal fungi (AMF) has been acknowledged. However, whether this AMF improved the quality of potato tubers is still need further investigation. This study was conducted to evaluate the effectiveness of AMF in enhancing potato quality and determine whether the addition of compost and biochar to soil can support the productivity of this biofertilizer in enhancing the nutrient content in the tubers of potato plant. Screen house experiment was set up in factorial design with treatments were organic matter types (compost and compost plus biochar), and application of arbuscular mycorrhiza (without and with AMF consisted of Glomus sp. and Gigaspora sp.). Results of experiment showed that there was no interaction effect between organic matter and AMF on quality of potato tubers, however, the in idual treatment especially AMF increased the content of protein and lipid of potato tubers. Biochar that added to soil with compost was also increased the lipid content of potato tubers. This finding showed that AMF application in potato production grown in poor P-soil was not only increased the yield of potato, but also increased the quality of potato tubers.

Abstract: Arbuscular mycorrhiza fungi (AMF) has been known can increase the productivity of many crops including potatoes. Growing medium is also vital for the growth of potatoes, especially in medium-high land. Good combination of AMF and growing medium is expected to improve the physical and biological soil properties and increase growth and seed production. An experiment aimed to evaluate the effect of AMF and different media composition on growth and yield of potato seeds G2 cultivars Medians in medium land has carried out at Jatinangor, Indonesia. The experiment used randomized block design with treatments: growing medium (soil + compost (2: 1), soil + compost + cocopeat (2:1:1), and soil + compost + charcoal husk (2: 1: 1) and AMF (without and with AMF). Results showed that there was interaction effect between AMF and composition of growing medium on percentage of stolon formed into tuber and weight of potato tubers per plant. Treatment of medium soil + compost + cocopeat (2:1:1) and the addition of AMF increased the percentage stolon formed into tubers as high as 84%, and potato tuber weight to 328 g plant. Growing medium consisted of soil + compost + cocopeat (2:1:1) increased plant height, plant dry weight, shoot root ratio, and number of potato tubers. This finding showed that AMF application combined with proper growing medium increased the the production of potato seeds.

Abstract: Purpose : The indigenous phosphate solubilizing stored in peat soil as a carier is still a prospect as an ingredient of biological fertilizer, so it still needs to review how the indigenus phosphate solubilizing area of Tanjungsari, Sumedang worthy to be used as an ingredient Biological fertilizer.Research Method : The experiment was conducted at the Faculty of Agriculture Univeritas Winaya Mukti with the land type Andisol and the altitude of 850 m asL, carried out in March to June 2019. Environmental design using random draft group combination repeated 3 times with treatment consists of 13 treatments that are a type of phosphate solubilizing combined with a dose of peat soil carier. The data was analyzed further with Duncan’s test at 5%. Findings : Results showed that the Tanjungsari’s indigenus phosphate solubilizing with peat soil effect on the Phosphate is available on the soil, Phosphate total domain, potato shoot root ratio, number of the cropping bulbs, the weight of the tuber per plant and the weight per tuber, but has no effect on pH Soil, bacterial population, cation exchange capacity soils and absorption Phosphate in plants.Limitations : This research is done at medium place height where not the optimum altitude for potato.Value : Phosphate solubilizing bacteria indigenous from Tanjungsari Sumedang with carrier materials peat soil has the potential to be used organic fertilizer.
