Abstract

In our country, marginal land occupy for about 50 million hectares or almost one forth of total land. In Sumatra, nearly all marginal land is dominated by podzolik soil which about 10 million hectares. The main problems of this soil are including low pH, high Al content, low cation exchange capacity, and poor of nutrient and organic matter level, therefore the growth and yield of plants can not be optimal. Traditionally, farmers use lime to solve this problem, but this method only influences the chemical aspect but not the biological one. The solution we offer in research is by applying biochar. It is high in carbon, porous and could improve soil fertility. This research aimed to know and evaluate the impact of biochar application on growth and yield of corn. The result showed that biochar gave positive impact on growth and yield of corn. By using biochar the corn height reached 155,67 cm while applying lime could only grew till 56 cm and 20 cm by using no ameliorant or control. Furthermore, the corn seed weight was thrice by biochar than by lime that were 194,5 g compared to 42 g per plant. Meanwhile, the corn plants were failed to produce yield in treatment of chemical fertiliser and control.

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
