Abstract

Synechococcus sp. is a species photosynthetic bacterium that has symbiotic mutualism with plant.  Research on this field is not many. Foliar application of this bacterium may increase the growth and yield characteristics.  The aim of this research was to determine the effect of Synechococcus sp. application and NPK fertilizer on soybean growth and yield.  The research was conducted in Pusat Inkubator Agribisnis (PIA) Jember University on February until May 2004.  Split plot design was used with 2 factors, Synechococcus sp. as sub plot (B0: without bacteria and B1: with bacteria application) and NPK fertilizers as main plot (P0: 0 g/plant; P1: 0.347 g/plant; and P2: 0.875 g/plant) with three replications. The result showed that the interaction between Synechococcus sp. and NPK fertilizers treatments was not significant.  The  bacteria applications significantly increasing plants growth (42.9%), leaf area index (294.6%), number of productive stem per plant (141.3%), number of productive nodes per plant (40.3%), pods weight per plant (175.2%), number of pods per plant (152.8%), grain weight per plant (80.5%), dry weight (209.8%), and 100 grains weight per plant (3.4%).  The fertilizers significantly affected only on plants growth (44.6%) and number of pods per plant (29.4 %).    Key words:  Glycine, Synechococcus sp., NPK

Abstract

This pot experiment was to evaluate the influences of cotyledons detachment at seedling stage on the efficiency of labelled N-urea uptake and proportion of N-fixation by soybean cv. Wilis grown under saturated soil culture. Based on the result of preliminary experiment, cotyledons detachment was held at 7 days after sowing (das). The cotyledons detachment significantly reduced N-urea uptake efficiency and N-fixed proportion. The N-urea uptake efficiency at 21 days, R4, R5, R6, and R8 stages by cotyledons-detached plant were 30.5 %, 24.6 %, 23.7 %, 24.0 %, and 22.45 of the total N assimilated. Those of the cotyledons undetached-plant (control plant), the value were 31.6 %, 24.05, 24.7 %, 2.7 %, and 23.6 % respectively. At R8 stage, the cotyledons-detached plant has the amount of N-fixed proportion of 54.2 and N-soil of 23.4 %, whereas those of the control one had the amount of 49.7 and 26.7 % respectively. N-urea uptake, N-fixed, and N-soil uptake by the cotyledons- detached plant were lower than that of the control one (i.e. 69, 80, and 645 of the control respectively). The cotyledons detachment also result in inferior vegetative and productive growth of the plant in terms of decreased root dry weight (21.1 %), leave dry weight (18.8 %), plant dry weight (26.7 %), pot dry weight (23.8 %), grain number/pot (32.8 %), and grain dry weight (26.9 %). It seems that the lower growth and yield of the cotyledons-detached soybean paint were caused by the lower total N-uptake due to cotyledons detachment.

Abstract

Identification of Indonesia sugarcane varieties tolerant to waterlogging has not been done extensively. Information on varieties tolerant to waterlogging is required for seedling establishment in waterlogged areas. The purpose of this research was to identify the sugarcane varieties responses to several duration levels of waterlogging at seedling stage. The planting materials used were collection of Sugar Factory Semboro including VMC 76-16, BL, PS 862, PS 864, and PS 881. This research was arranged in randomized complete block design (RCBD) with two factors and three replications. The first factor was 5 varieties; the second factor was waterlogging treatment with four levels, i.e. without waterlogging, 2, 4, and 6 weeks of waterlogging in the bucket. The results showed different level of tolerance to water logging among the varities. PS 881 and VMC 76-16 varieties were the most tolerant to waterlogging supported by its ability to maintain plant height, root volume, root and shoot dry weight after been waterlogged for 6 weeks. These varieties were also able to establish aerenchyme tissue and increased the stomatal density. PS 862 was the least tolerant variety to waterlogging. Keywords: aerenchyme, morphology, stomatal density, waterlogging, water stress

Abstract

Hoya carnosa (L.) R. Br. propagation is conventionally less efficient, and the amount produced is low. This study aims to determine the influence of hormone type and concentration on changes in cell structure and the phase of somatic embryogenesis of the Hoya plant in vitro. The study was conducted in two stages, namely the first stage of callus induction with a combination of BAP (0.4 mg/l, 0.5 mg/l, 0.6 mg/l) and 2,4-D (5 mg/l, 6 mg/l, 7 mg/l) and the second stage of somatic embryogenesis with a combination of BAP hormones (0.5 mg/l, 1.0 mg/l, 1.5 mg/l) and IBA (0.25 mg/l, 0.5 mg/l, and 0.75 mg/l). The data were analyzed using ANOVA and further analyzed by using DMRT. Based on the results, the combination of BAP 0.4 mg/l and 2,4-D 7 mg/l hormones showed the best growth with the parameters of the appearance of callus at 23 days, callus weight 2.92 g, and embryogenic calluses formed with crumb texture and greenish-yellow color. The combination of BAP 1 mg/l and IBA 0.75 mg/l resulted in the frequency of budding emergence of 23.3 days and the number of tendrils 20.7. This treatment was able to produce 5 roots and 2 shoots.

Abstract

The majority of residents in Suling Wetan Village work as farmers and rely heavily on self-produced seeds due to the village’s remote location. One high-potential crop for marginal lands in the area is patchouli (Pogostemon cablin), a plant valued for its essential oil. However, the propagation of patchouli remains a significant challenge for local farmers due to limited knowledge and skills. This community engagement program aimed to enhance farmers’ capacities in patchouli propagation through a combination of awareness campaigns, technical workshops, hands-on training, direct field mentoring, and participatory monitoring and evaluation. Evaluation was conducted through direct observation and participant surveys. The results showed that 96% of participants gained a clear understanding of patchouli propagation techniques, and all participants acknowledged the importance of the program and expressed hope for its continuation. The activity successfully contributed to increasing farmers’ independence in sustainable patchouli seedling production.
