Phosphate solubilization potential of rhizosphere fungi isolated from satoimo taro plant Eka Wisdawati (a*), Tutik Kuswinanti (b), Ade Rosmana (b), Andi Nasruddin (b) a) Department of Production Technology of Plantation Crop, Pangkep State Polytechnic of Agriculture, Pangkep 90655, Indonesia b) Department of Plant Pest and Disease, Faculty of Agriculture, Hasanuddin University, Makassar 90245 Indonesia Abstract Phosphorus is an essential nutrient required by plants for their growth and development. Phosphates bioavailability in nature is approximately 95 until 99% but insoluble, therefore the plant can not simply use them. The alternative to overcome phosphate deficiency is by utilizing phosphate solubilizing fungi. This research is aimed at selecting and characterizing phosphate solubilizing fungi in rhizosphere of saitomo taro (Colocasia esculenta var antiquorum). The test on isolate ability to solubilize phosphate was conducted through qualitative and quantitative. Qualitative was carried out by counting index of phosphate solubilization on solid Pikovskaya while quantitative was through counting concentration of phosphate solubilization through spectrophotometry at wave length 693 nm. The result of qualitative test showed that the highest index of phosphate solubilisation was 1.08 at isolate RTP25 while quantitative demonstrated that isolate RTP16 released highest concentration of phosphate solubilization with the amount 12.78 Ug/l. Isolate RTP 25 (by Trichoderma sp) and Isolate RTP16 (by Aspergillus sp) be potential to be developed as phosphate biofertilizer.

Jayadi, Nirmala Juita, Balqis Nur Aisyah Department of Soil Science, Faculty of Agriculture, Hasanuddin University, Makassar, Indonesia, 90245 *riskynurhikmayani[at]unhas.ac.id Abstract The development of the agricultural sector in North Luwu has an impact on land use change to increase plantation production. Continuous use and clearing of land can threaten the loss of native land vegetation, affecting the C and N cycles, community composition, population and soil microbial activity. Microorganisms are important in the maintenance of soil health and quality. The abundance of soil microorganisms has a major influence on ecosystem function so it can help increase production in the agricultural sector. This shows that data on the abundance and diversity of soil microbial can be a reference in determining soil fertility. However, there is still little data on the abundance of soil microbes in North Luwu. This study aims to determine the abundance of soil microbial, especially on different land use. Soil sampling was carried out randomly on three land use: cocoa monoculture, cocoa agroforestry and secondary forest. The soil samples obtained were then measured for the C:N ratio and total microbes. The results showed that agroforestry cocoa with the highest C:N ratio had 1,8 x 108 CFU/g of total soil microbial, the highest microbial abundance among the three land covers followed by secondary forest and monoculture cocoa with the lowest C:N ratio and lowest microbial abundance 2 x 107 CFU/g. These results indicated that different land use has different microbial abundance which is influenced by soil C:N ratio.

Prof. Dr. Ir. Sumantri Brojonegoro, Gedong Meneng, Rajabasa, Bandar Lampung, Lampung 35141, Indonesia Abstract The length of the green-life period is an important parameter in the export of Cavendish bananas. Conventional methods in determining green-life are still relatively difficult to be standardized because they are subjective. The initial phase shift from green to yellowish-green as the end of green-life is very difficult to detect and quantify with naked eyes. Therefore, we need a standard method that can be used to determine its green-life. The purpose of this study was to test a new method for determining the green-life based on image processing data of Cavendish bananas after receiving postharvest treatments. The data were collected from Cavendish bananas at various maturity levels which had received postharvest treatments of fruit coatings and storage temperatures. The results showed that intensity of red (I-Red) increased, while intensity of green (I-Green) decreased until the end of observation. Green life was ended when I-Red showed a greater value than I-Green. According to the method, Cavendish bananas in cold temperature storage showed a longer green life than room temperature storage with average of 26.33 days and the longest was 35 days. Meanwhile, storage at room temperature showed average green life length of 14.25 days with the longest period was 16 days.

Soil provides nutrients as food ingredients needed by plants to support their growth. Productivity and plant growth are strongly influenced by the physical and chemical soil properties. The study aimed to analyze the physical and chemical soil properties of the Grand Forest Park (Tahura) of Nipa-Nipa Kendari for both utilization and protected block areas. The Sampling was carried out at the Kendari Nipa-Nipa Kendari Forest Utilization and Protection Blocks and in four months, namely June to September 2022. Furthermore, analysis of soil properties was carried out at the Laboratory of Silviculture and Tree Physiology, Faculty of Forestry, Hasanuddin University. The soil samples were taken from disturbed soil collected from 27 predetermined measuring plots. Measuring plots were placed by purposive sampling at five distinguished altitude levels. Soil samples were taken at 5 points and three soil depth namely 0-20 cm, 20-40 cm and 40-60 cm, respectively. Correlation Analysis applied Principal Component Analysis (PCA) by using Minitab 18 software. The study revealed that the Nitrogen, Phosphorus, and Potassium in the protected block area was higher than the utilization block area. In general, the soil pH content in each block showed that the deeper soil was the higher pH and the moister of the soil. The high nutrient content in the Protected block area was affected by the condition of the forest which is still maintained, so that the micro and macro nutrient cycles can proceed properly. While, the utilization block area has been converted into plantations which has resulted in an imbalance in the nutrient cycle. The high soil pH was thought to be caused by the leaching of the soil surface by surface run-off and soil erosion, while the high soil moisture is thought to be due to soil sampling carried out after the rainy season.

Assessing True Shallot Seed (TSS) Performance and Farmers^ Perceptions of Its Innovation Attributes Witono Adiyoga Research Center for Behavioral and Circular Economics, National Research and Innovation Agency Jl. Gatot Subroto - Jakarta Abstract True Shallot Seed (TSS) cultivation is a new shallot production technique that does not use vegetative tubers as planting material, but rather seeds. This study aimed to examine the field performance of TSS and assess farmers^ perceptions of TSS innovation attributes. On-farm participatory trials involving eight farmers were conducted in Cirebon and Brebes during June-August 2020. Compared to Trisula and Maserati, Sanren^s performance was the best in both nursery and transplanting stages. Maserati showed the second best performance in seed emergence and yields. Meanwhile, although farmers had rated Trisula high scores for color, pungency, and bulb shape, poorer yields made Trisula the least financially viable than the others. Basically, all farmers responded positively to TSS innovation attributes (relative advantage, compatibility, complexity, trialability, and observability) which indicated high likability to TSS. Farmers perceived TSS to provide higher yields, better tuber quality, and higher profits. In the meantime, farmers also considered TSS cultivation to be more costly and risky to pests and diseases. However, a strong intention to adopt TSS was expected given the overall positive attitude of farmers towards TSS.

Van Gobel No. 270, Bone Bolango, Gorontalo 3)Food Crop Research Center, National Research and Innovation Agency, Bogor Highway Street Km. 46, Cibinong, West Java Abstract Rice is the main food crop for the people of Indonesia whose availability is always sought, one of which is by increasing the cropping index using improved variety of very early maturing rice. An increase in the cropping index causes the land to be cultivated more intensively and can have an impact on decreasing Silica content. Therefore, to support the growth of rice plants, especially on land that is intensively cultivated, it is necessary to add Silica elements. This research aims to study the effect of biosilica on the growth of the vegetative phase of several very early maturing rice varieties. The research was conducted from September to December 2022 in Gorontalo using a Split Plot Design (SPD).The variety (V) as the main plot consisted of three treatment levels, namely the Cakrabuana variety (v1), the Inpari 13 variety (v2), and the Inpari 19 variety (v3). Then, as a subplot, consist of the dose of liquid biosilica (D) which consisted of four treatment levels, namely without biosilica as a control (d1), biosilica 1.5 l/ha (d2), biosilica 3 l/ha (d3) and biosilica 4, 5 l/ha (d4) so that there are 12 treatment combinations with 3 repetitions for each treatment. The results indicated that the use of liquid biosilica in several improved varieties of very early-maturing rice showed a significant interaction of plant growth in the vegetative phase.We can see this in the highest plant height in the v3d3 treatment, the highest number of tillers is v1d2, the smallest flag leaf angle is in the v1d1 treatment but not significantly different from the v3d3, the best number of stomata and stomata density can be found in the v3d4 treatment. In addition, the variety and dose of biosilica 3.0 l/ha have the best effect on the development of blast disease intensity. Keywords: Rice, variety, very early maturing, biosilica.
