Abstract

This study aims to obtain soybean varieties that are able to grow well and produce high in biocomposite coastal areas. This study was compiled using Randomized Block Design (RAKL) with single factor consisting of four varieties of soybeans namely Wilis, Grobogan, Detam I and Detam II. The results showed that the varieties of Wilis produce the highest plant height 63,13 cm, the highest percentage of pods per plant is 91,12%, the highest number of seeds per plant is 249,56 pieces, the heaviest seed weight per plant is 30,92 gram, while the Grobogan which produce the heaviest dry weight is 7,92 g, the highest K absorption is 0,22 g and the highest 100 seed weight is 18,00 g. Thus, the varieties of Wilis and Grobogan have higher adaptation rates than the Detam 1 and Detam II varieties, which has the potential to be developed in coastal areas.

Abstract

The purposes of this research are (1) to know the influence of genotype and biological fertilizer to the soil biological properties, and (2) to know the influence of genotype and biological fertilizer to the soybean plants productivity at its ultisols. This experiment was conducted at experimental garden of Bengkulu University. It was arranged in factorial split plot design and consisted of two factor. The first factor was soybean cultivars i.e. Pangrango, Ceneng, and DS1 (Malabar and Kipas Putih variety breeding). The second factor was double inoculation of Rhizobium and VAM i.e. Glomus manihotis + Rhizobium of KLR 5.3 strain, Glomus manihotis + Rhizobium of TER 2.2 strain, Gigaspora margarita + Rhizobium of KLR 5.3 strain, Gigaspora margarita + Rhizobium of TER 2.2 strain, fertilizer NPK at recommended dosage without inoculants respectively. The collected data was analyzed statistically and tested by F test at level of 5% and continued with Duncan Multiple Range test for differences among the treatments. The result of the research showed that (1) the soil that had been planted genotype DS1 soybean has the highest level of C-Organic (2,69%) compare with pangrango or ceneng and biological fertilizer produces higher level of respiration than its control. (2) ceneng’s genotype produce the effective amount of nodules, plant dry weight (3,90 g), and seed weight (5,66 g) is higher than if we compare with pangrango and DSI.Keywords : soybean, biofertilizer technology , Ultisols

Abstract

[EFFECT OF MYCORRHIZAL BIOFERTILIZER AND CHICKEN MANURE ON GROWTH AND YIELD OF COWPEA (Vigna sinensis L.) IN ULTISOL]. This study aims to 1) obtain the interaction of mycorrhizal biofertilizers and chicken manure on cowpea in ultisol and 2) determine the best dose of mycorrhizal biofertilizers for the growth and yield of cowpea plants, also find the best dose of chicken manure on the growth and yield of string beans. The study was conducted in April 2019 at the experimental garden, Integrated Zone of the Faculty of Agriculture, UNIB, Kelurahan Kandang Limun, Muara Bangkahulu District, Bengkulu City. This study used a factorial Randomized Completely Block Design (RCBD) with two factors and three replications. The first factor is the administration of a dose of mycorrhizal biofertilizer, i.e., 0 (without mycorrhizae), 2.5 g/plant, 5 g/plant, and 7.5 g/plant. The second factor is the provision of chicken manure doses of 5 tons/ha, 10 tons/ha, and 15 tons/ha. Each experimental unit consisted of 25 plants with some sample plots of 5 plants. There is an interaction between mycorrhizal fertilizer 5 g / plant with chicken manure 5 tons/ha, which gives the best results on variable weight pod pods equal to 1.55 kg/m2 and pod weight of 15.46 kg/ha. The application of mycorrhizal biological fertilizer at a dose of 5 g/plant has good vegetative growth compared to other mycorrhizal doses. It shows the highest results based on the average number of flowers/plants and the number of pods/plants. Doses of chicken manure up to a dose of 15 tons/ha do not significantly increase growth and yield of cowpea.

Abstract

Soil water availability to the plants is a range of water content between the field capacity and the permanent wilting point (PWP) conditions. The PWP is defined as the lower limit of soil water content that the plant can extract water from the soil as indicated by the symptoms of wilting plants. This is because plant roots are unable to penetrate the soil micropores that contain the water.  The study aims to analyze the effects of arbuscular mycorrhizal fungi (AMF) and compost in enhancing soil water absorption by the plant when the water content is close to the permanent wilting point. Four doses of AMF (0, 5, 10 and 15 g.plant-1) and three doses of coffee pulp-made compost (0, 5 and 10 ton.ha-1) were arranged according to a randomized complete block design with three replicates. Results showed that the application of AMF significantly enabled the plant to improve water uptake when the soil water content was about at the permanent wilting point conditions. The AMF addition of 15 g.plant-1 significantly prolonged the growing period of chili to wither and the plant showed the wilting symptoms at the soil water content of 5 to 7% lower than the no-AMF plants. Improved water uptake under water stress conditions was attributed to increases in the root colonization by AMF.
