Abstract

This study aims to determine the characteristics of soil pores and therelationship of pore characteristics with soil permeability. Soil samples were collected from Punagaya Village, Bangkala District, Jeneponto Regency, South Sulawesi. Soil samples were taken from 20 observation points representing two types of land use ie cultivated land and fallow field at a depth of 0-60 cm. Soil analysis (pH, organic material, C-organic, cation exchange capacity, bulk density and soil texture), Pore characteristics(porosity, pore distribution and pore stability), and permeability. Analysis of soil properties and pore characteristics was descriptive, while the relationship between pore characteristics and permeability was analyzed by single or multiple regression and correlation analysis. The results showed that the permeability of soil vertisol 0.29 cm/h (slow) and the average value of soil pore characteristics of vertisol as follows: porosity ranged 56.49%, fast drainage pore 4.35%, water pore available 17.8% And 32.5% micro pores, and 36.46% pore stability. Based on the regression and correlation test, it is known that Porosity and porosity and pore stability index have the greatest influence on permeability.

Abstract

The purpose of this study was to examine the effect of the growth of green bean local varieties of Sabu at different spacing and liquid fertilizer and to determine the relationship between sunlight interception and plant growth.The experimental design used was a factorial randomized block design with two factors, namely spacing is Plant spacing 40 cm x 20 cm , 40 cm x 25 cm , 40 cm x 30 cm and Type of Liquid Organic Fertilizer namely: NPK plus fertilizer, Nasa POC,Green Tonic Liquid Fertilizer, and POC ABG. The results showed that the difference in spacing and the type of liquid fertilizer affected the number of productive branches and the percentage of sunlight interception at the age of 5 week after planting (WAP) but did not influence other growth components. Spacing affects plant height at the age of 3 and 4 WAP and the percentage of light interception.  Key Words: interception, plant growth, spacing, and liquid fertilizer

Abstract

The purpose of this study was to obtain the best concentration and interval of application of POC ABG to increase the yield of local varieties of mung bean Sabu.RBD with two factors was used in this study namely, factor 1(concentration): 2, 4, 6, and 8 ml LOF/liter of water; factor 2 (interval): 7 and 14 days once. Data were analyzed using ANOVA and further test using DMRT 5%.The results showed that there was no effect of POC ABG treatment on the number of seeds/pods and the weight of 100 seeds. POC ABG concentrations of 2 and 4 ml/liter of water and application intervals of 7 days gave the highest seed yields per plot (240.73 grams and 238.84 grams) and 240.66 grams. The interaction of treatment 4 ml/liter of water and application interval of 7 days gave the number of pods planted (15.22) and the highest seed yield (9.63 grams). Key Words:  Concentration, interval, ABG, mung beans local var Sabu

Abstract

This study aims to study the types of minerals and chemical properties of Vertisol soil that develop from limestone rocks in Jeneponto Regency, South Sulawesi. Taking soil samples is carried out at four different depths, namely: 0-15 cm, 15-30 cm, 30-45 cm,  and 45-60 cm. Observation parameters for soil mineral types are primary minerals and secondary minerals, while soil chemical properties observed are pH, C-organic, cation exchange capacity (CEC). The results showed that the dominant primary mineral species were calcite and quartz, the dominant secondary mineral species was montmorillonite. Soil chemistry for soil pH ranges from 6.58-6.85, C-organic ranges from 2.23-2.81% or moderate status, and CEC ranges from 19.98 to 22.76 cmol (+) / kg or moderate status.
