“…Rhizobium inoculation on soybean plants has a long been known as one of the biological fertilizers. In soybean plants to produce 1 kg of seeds, plants absorb 70-80 grams of nitrogen from the soil so that if the yield of 1.5 tons/ha it will absorb 105-120 nitrogen from the soil (Purwaningsih et al, 2015). The factors which control the amount of nitrogen fixed include available soil nitrogen, genetic determinants of compatibility in both symbiotic partners and lack of other yield-limiting factors like edaphic factors associated with phosphorus deficiency (Harold et al, 1992).…”

Background: Soybean is one of the major oil seed crops in Bangladesh. Combine application of Rhizobium inoculation and phosphorus fertilizer could be an important factor to get maximum yield and quality of soybean. Objective: To evaluate the effect of Bradyrhizobium inoculum and levels of phosphorus on yield and quality of soybean varieties. Methodology: The experiment evaluated three factors namely, varieties, Bradyrhizobium inoculum and phosphorus levels. The three varieties were: i) Binasoybean-1 ii) Binasoybean-2 and iii) BARI Soybean-6. Bradyrhizobium inoculum levels were: i) control (no inoculum), ii) 50% of recommended dose (RD) (25 g kg-1 seed) iii) 100% of RD (50 g kg-1 seed). The phosphorus levels were: i) control (no phosphorus) ii) 50% of RD (18 kg ha-1), iii) 100% of RD (36 kg ha-1). The experiment was laid out in a randomized complete block design with three replications. Data were recorded on yield, yield contributing characters and quality parameters of seeds. Results: Binasoybean-1 performed superiorly in terms of all the yield and yield contributing characters. Application of 100% of RD of Bradyrhizobium inoculum and application of 100% of RD of phosphorus also showed superior performance. Considering the interaction effect, the findings of the study indicate that Binasoybean-1 responded well to the application of 100% of RD of phosphorus and 100% of RD of Bradyrhizobium and gave maximum seed yield. The highest protein content (39.21%) was found in Binasoybean-2, 50% of RD of phosphorus with no Bradyrhizobium inoculum and the highest oil content was found (19.33%) in Binasoybean-2, no phosphorus and 50% of RD of Bradyrhizobium inoculum. Implication: Binasoybean-1 with the application of 100% of RD of phosphorus and 100% of RD of Bradyrhizobium might be recommended to obtain higher yield soybean in Bangladesh. Conclusion: From this study it may be concluded that recommended dose of phosphorus and Bradyrhizobium is beneficial for a higher yield of Binasoybean-1.

Objective: The purpose of writing this article is to evaluate the management of rice straw waste in the Subak Sembung ecotourism area, Denpasar. This includes assessing the implementation of the LEISA concept and prioritizing ecological concepts Theoretical Framework: Subak Sembung as an ecotourism area should manage waste by prioritizing ecological principles, including implementing the LEISA concept. The implementation of LEISA in the Subak ecotourism area is a characteristic of sustainable agriculture Method: The method used in this research is qualitative research which aims to understand phenomena that occur in society. The sample in this study was 30 farmers who were selected using simple random sampling techniques Results and Discussion: Based on the research results, it was found that rice straw waste in the Subak Sembung ecotourism area has not been managed by Bali Governor Regulation Number 47 of 2019 concerning source-based waste management. The LEISA concept has not been implemented optimally, where only 29% of farmers compost and use compost to reduce the use of inorganic fertilizers. The LEISA concept has not been implemented optimally in Subak Sembung because based on the results, 94% of farmers in Subak Sembung do not know about the LEISA concept. Research Implications: Socialization and training in rice straw waste management for Subak Sembung member farmers need to be carried out more regularly and continuously so that the LEISA concept can be implemented. Originality/Value: Implementation of the LEISA concept through agricultural waste management in the Subak area, which is an ecotourism area, can be an effort to realize sustainable agriculture and tourism simultaneously
