“…Water precipitation fluctuated during soybean growth and was lowest on the first 30 Days After Planting (DAP) (52.07 mm), highest at 61-90 DAP (364.89 mm), and decreased at 91-120 DAP (247.62 mm) (https://climate.nasa.gov/). Annual crops have a water requirement of approximately 70 mm per month and thus require a precipitation level of 120 mm monthly (Fuadi et al 2020). Therefore, water precipitation was excessive during this study.…”

Abstract. Permanasari I, Sulistyaningsih E, Kurniasih B, Indradewa D. 2023. Morphophysiological and yield traits of soybean varieties tolerant of intercropping with maize. Biodiversitas 24: 3872-3880. Not all soybean varieties grow optimally when intercropped with maize. Previously, we identified seven varieties (i.e., "Demas 1", Dena 1", "Dena 2", "Derap 1", "Devon 1", "Devon 2", and "Wilis") and two (i.e., "Dega 1" and "Mahameru") as tolerant and intolerant of intercropping based on selection indices and yield. This research aims to determine the morphophysiological and yield traits of tolerant and intolerant soybean groups intercropped with maize. The study used a randomized complete block design with three blocks as replications, and conducted from October 2019 to February 2020. Results showed that light intensity in the intercropping system had decreased by 19.91% relative to that in the monoculture system at 7 weeks after planting. The tolerant group displayed significant gains in seed weight per plant (143.66%), total biomass (50.04%), harvest index (53.33%), total number of pods and seeds per plant (119.39% and 128.86%), leaf nitrogen uptake and content (20.83% and 6.44%), chlorophyll-a:b ratio (7.20%), and stem diameter (7.65%) than the intolerant group. Correlation analysis revealed that leaf nitrogen content showed the highest correlation and significantly contributed to seed weight per plant in the tolerant and intolerant groups. Seed weight in the tolerant group was mainly affected by morphological (total biomass and harvest index), physiological (leaf nitrogen content), and yield components (number of pods), whereas that in the intolerant group was influenced only by physiological parameters (nitrogen content). Nitrogen content was considered suitable as a selection indicator for determining the seed yield of intercropped soybean varieties. Furthermore, using soybean tolerant groups for intercropping may be a solution to increase soybean production in Indonesia.

Jambi province is included in the soybean belt areas and one of the soybean seed production centres in Sumatra. Fulfilling the soybean production demand of the Jambi region also in surrounding provinces, the seed program is one of the main requirement. This paper aims to provide an overview of the soybean seed production program through innovation technologies and dissemination for Jambi. An action research was carried out from 2016 to 2018 in the Tebo and East Tanjung Jabung regions, involving seven breeding farmers, local governments, research centres and other stakeholders. Activities carried out in the form of demonstrations plot, demonstrations farm, and technical assistance activities. The results showed that more than 100 tons of newly soybean certified seeds (Anjasmoro) were distributed from soybean production areas to other areas in Jambi and to other provinces such as: Riau, West Sumatera, South Sumatera and Aceh). Agronomic data and yield parameters in soybean seed activities from research site were showed minor significant differences compare to farmer practices technologies. Some innovation technologies were introduced i.e. good agricultural practices, and good handling practices for soybean seed farmers. Through this activity, soybean seeds are available throughout the year (2016 up to recent).
