Extensionist agents as one of the important spearheads in advancing agriculture in Indonesia. By counseling will provide information, knowledge, and skills to farmers in trying to farm. One of the factors in improving the knowledge and skills of farmers is to provide effective and efficient extension learning method. This study aims 1) Analyze the Method of agricultural Extension in Maros Baru Sub-district Maros Regency 2) Analyze the influence of Agricultural Extensionist Method in improving Farmers Knowledge and Skills in Maros Baru sub-district. This research was conducted for approximately 3 months, starting from May to July 2018, with the research location is in District Maros Baru. The sample in this study is the existing farmers in the District Maros Baru, with the sampling system by proportional sampling. The method of data analysis are: 1) Qualitative Descriptive Analysis and 2) Test t. The result of the research shows that: A) The Agriculture extension which is categorized as very high is Demplot, Anjangsana, Training and Field School, While the Method of learning extension that as high category is Temu wicara and comparative study. B) The overall agriculture extension Methode is influential in increasing the knowledge and skills of farmers.

This study aimed to obtain the composition of biochar as a soil enhancer and mycorrhizal dose, which affected the nutrient uptake of cayenne plants. This experimental research was based on a separate plot design (RPT) with a basic randomized block design (RCBD). The main plot experiment was vesicular-arbuscular mycorrhiza or VAM (m) with three levels: mycorrhiza 10 g/plant (m1), mycorrhiza 15 g/plant (m2), and mycorrhiza 20 g/plant (m3). The subplot is biochar composition as soil enhancer (b) with three types: biochar husk 50%+25% soil+25% sand (b1), 50% sand+25% soil+25% biochar wood (b2), and wood charcoal biochar 50%+soil 25%+biochar charcoal husk 25% (b3). Each level of the VAM doses factor is combined with biochar. These nine treatment combinations and the levels were repeated thrice, accounting for 27 experimental units. The results showed that the parameters of phosphorus uptake, potassium uptake, and fresh root weight had a positive and significant relationship to the percentage of mycorrhizal infections. The combination treatment of mycorrhiza 20 g/plant and the composition of 50% husk biochar+25% soil+25% sand, 15 g mycorrhizal dose treatment with 50% wood biochar+25% soil+25% biochar rice husk and 20 g/plant are the best treatment as a planting medium.

The study aimed to classify soybean genotypes that are tolerant, moderate and sensitive to drought and acidity. The results are expected to give a contribution in the development of Soyban on dry land and acid soil.  Increasing of genetic diversity was carried out through mutation induction by gamma ray in soybean seeds. The experiment was conducted in green house by using the method in the form of a two-factor factorial design laid out in the draft group. The first factor was the variety (V) which consisted of three kinds, namely soybean Menyapa varieties (v1), Orba (v2), and Tanggamus (v3). The second factor was the dose of gamma-ray irradiation (D) consisted of 4 doses of 0 Gy (d0), 25 Gy (d1), 50 Gy (d2), and 75 Gy (d3) at concentrations of PEG and Al which showed that the level of diversity the biggest concentration of 30 previous trials of PEG+10 ppm Al. The volume of nutrient solution (Hoagland's) maintained in accordance with the initial volume by adding distilled water, and the solution was maintained at pH 4 using NaOH and HCl 1N. The results showed that the grouping was based on drought tolerant and acidity as follows: genotypes tolerant were varieties Menyapa 50 Gy gamma irradiation, variety of Orba 25 Gy of gamma irradiation, gamma irradiation variety Tanggamus 0 Gy, 25 Gy, 50 Gy of gamma iradiation. Moderate genotype were varieties Menyapa 75 Gy of gamma irradiation, variety Orba 50 Gy, 75 Gy of gamma irradiation, variety Tanggamus 75 Gy of gamma irradiation; genotype susceptible were variety Menyapa 0 Gy, 25 Gy of gamma irradiation; variety Orba without gamma irradiation of 0 Gy.
