Abstract

Root nodulation is a crucial process for legumes, including edamame (Glycine max (L.) Merr.), as it enablesbiological nitrogen fixation, enhancing nitrogen availability for plant growth. The implementation of Rhizobium inoculumhas been demonstrated to reduce the necessity for synthetic fertilizers, thereby enhancing the health and yield of the plantsin question. Furthermore, optimal plant population management ensures adequate access to light, water, and nutrients,maximizing productivity. The combination of Rhizobium inoculation and population management represents a crucialstrategy for enhancing the productivity and sustainability of legume crops, such as edamame. This study examines theimpact of Rhizobium inoculation and plant population management on the nodulation and productivity of edamame. Theresearch was conducted using a randomized block design, with two factors: the application of Rhizobium (Bradyrhizobiumjaponicum) at two levels (without inoculation and with inoculation) and plant spacing (20 x 15 cm and 20 x 30 cm). Eachtreatment was replicated five times. The observed parameters included number of root nodulations, plant height, leaf area,leaf greenness, number of filled and empty pods, weight of filled and empty pods, wet weight, and 100 seed weight. Thedata were subjected to analysis of variance, followed by Duncan's Multiple Range Test. The findings indicated thatRhizobium inoculation markedly enhanced root nodulation, with the 20 x 15 cm spacing in conjunction with inoculationyielding the highest total nodulation, number and wight filled pods, wet weight, and 100 seed weight.

Abstract

Spenochela zeylanica is the most prevalent weed of paddy rice in Indonesia, and therefore its presencenecessitates control in order to reduce the potential for yield losses. The use of chemical herbicides as a control method isprevalent, but their environmental impact and potential for inducing weed resistance are significant drawbacks. It istherefore necessary to identify control methods that are environmentally friendly and capable of overcoming weedresistance. The leaves of Chromolaena odorata have allelopathic properties that could be harnessed for use as abioherbicide. The objective of this study is to evaluate the efficacy of C. odorata leaf extractions using diverse organicsolvents as a bioherbicide for the management of S. zeylanica. This study used a randomized group design (RBD) with 11treatments and 3 replications, including: T0: no treatment; 96% ethanol extraction: T1(5%), T2(10%), T3(15%); ethylacetate extraction: T4(5%), T5(10%), T6(15%); aquadest extraction: T7(5%), T8(10%), T9(15%); T10: 2,4-D herbicide(648 g a.i./ha). The findings indicated that the extraction of C. odorata using various organic solvents exhibited promise asa bioherbicide, displaying the capacity to poison weeds up to 100% (T2, T3, T6, T8, T9) and effectively suppressing theheight, root development, and chlorophyll content of S. zeylanica.
