The supply of nitrogen (N) to the carioca bean plant via inoculation with Rhizobium tropici can prevent competition with the weed community by allowing the crop to absorb the nutrient available in the soil. On this basis, this study proposes to examine the period before weed interference (PBI) in the carioca bean plant following inoculation with R. tropici or N topdressing. The experiments were carried out under field conditions during the summer seasons of 2014 and 2015. A randomized-block experimental design with four replicates was adopted, in a 2 × 11 factorial arrangement (common bean plant inoculated or topdressed with N × 11 periods of coexistence with weeds, namely, 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, or 90 days after emergence [DAE]). Nitrogen topdressing increased the crop's tolerance to coexist with weeds from 6 to 14 DAE, compared with inoculation with R. tropici The PBI for the inoculated common bean plant was 24 and 16 DAE in the years 2014 and 2015, respectively. For the N-topdressed plant, the PBI was 30 DAE in both years.

This community service activity is motivated by the large amount of waste from bean plants in Tongkok Village, Lahat Regency which has not been used optimally, especially as liquid fertilizer. Waste from the bean plant is disposed of, burned and not used . This causes a high volume of waste and environmental pollution. Therefore, the pkm stkip pgri lubuklinggau team tried to socialize the use of bean plant waste (phaseolus vulgaris, l) as liquid fertilizer in tongkok village. This PKM has been carried out by involving partners, namely the Tongkok village community and is enthusiastically followed. The output target to be achieved by the PKM team is to increase community values ​​and publications. In its implementation, it uses theoretical and practical methods starting from the preparation stage, providing materials and practices for making liquid fertilizer for bean plant waste

The more population grows, the more the food demand required. In this case, soybean, due to the less production compared to rice. In order to support food self-sufficiency and soybean demands, tropical legumes are cultivated due to its nutritional content which is similar to soybean. The local Indonesian plant, jack bean has adaptive properties to sub-optimal land. It can adapt to various cultivation systems, high productivity, and similarity of nutritional content to soybean. It has quite unique adaptations which can grow its upright stems or grows vines, depends to the environment, and relatively shorter age than another type local bean plants. Jack bean seeds can be further processed into tempeh, powder, bakpia (Indonesian traditional sweet cake which using nuts for the filling), and various cakes as a substitute for soybean, mung bean, and wheat. Therefore, the jack bean plant has a great potential as food self-sufficient Indonesia’s program.

Among the nutrients, nitrogen (N) is the element required in greater quantity by the bean plant. Depending on the cultivar, it has greater or lesser N-fixing capacity. The aim of this work was to evaluate the performance of two common bean cultivars under nitrogen topdressing in corn succession, on yield components and yield. The experiment was carried out in randomized blocks in a 2x5 factorial scheme, the first factor being the common bean cultivars (IPR Campos Gerais and BRS Estilo) and the second factor the nitrogen rates (0, 30, 60, 90 and 120 kg ha- 1), with four repetitions. At harvest, plants were collected in one meter, in the useful area of ​​each subplot to determine: number of plants per meter; number of pods/plant; number of grains/plant; number of grains/pods; mass of a thousand grains and productivity. The cultivars differed regarding the number of pods per plant, grains per plant and yield, but they were equivalent for the number of plants per meter, grains per pod and mass of a thousand grains. Comparing the production component number of pods per plant and grain yield, it is concluded that the cultivar that produced the highest number of pods per plant and showed the highest yield was BRS Estilo. There were differences between the treatments for the two cultivars, only in the yield obtained. The highest yield averages were obtained in treatments with doses above 60 kg ha-1 of N.

Spissistilus festinus (Say) (Hemiptera: Membracidae) was shown to transmit Grapevine red blotch virus (GRBV) in a greenhouse study. Grapevines infected with GRBV exhibit reduced sugar accumulation, altered secondary metabolite production and delayed berry maturation that negatively impacts wine quality and economics. Augmentative biocontrol may be a useful integrated pest management (IPM) tool for suppressing S. festinus populations in vineyards, but minimal research has been conducted on testing potential predators against the different life stages of S. festinus. The susceptibility of S. festinus adults and nymphs (1st through 5th instar) to predation by six commercially available biocontrol agents in petri dish and bell bean plant arenas was determined under greenhouse conditions. No significant mortality of S. festinus nymphs or adults occurred when exposed to Cryptolaemus montrouzieri adults, C. montrouzieri larvae and Sympherobius barberi adults in petri dish or bell bean plant arenas. Significant mortality of 1st and 2nd instar nymphs of S. festinus in the presence of Zelus renardii nymphs was observed in petri dish but not in bell bean arenas. Hippodamia convergens adults and Chrysoperla rufilabris larvae both consumed a significant number of S. festinus nymphs in petri dish and bell bean arenas. No significant predation of S. festinus adults was documented in this experiment. Results of this study aid in identifying predators that may be suitable candidates for additional field testing to determine their potential efficacy as biocontrol agents of S. festinus in a vineyard setting.
