“…Currently, the Government of Tebo and East Tanjung Jabung Regency have synchronized activities with national and provincial programs to increase soybean productivity, harvested area and Farming Index. This was to implement a national program launched by Directorate General of Food Crops and IAARD in the form of assistance by extension workers/researchers and seeds production program [10,11], in which AIAT Jambi was involved as a working unit of IAARD.…”

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).

“…Improvement of maize production through extending crop area has strict obstacles because the convertion of agricultural land to non-agricultural purposes (Maulana et al 2019). The utilization of suboptimal land such as sulfate acid soil tidal swamp areas to increase national maize production in Indonesia is an opportunity since the land is widely available, about 4.3 million hectares of tidal swampy areas can be managed as crop cultivation area (Surahman et al 2018). Pyrite oxidation in the soil layer was the main restriction to developing maize crops on the sulfate acid soil tidal swamp to manage the land.…”

Abstract. Suwarti, Ghulamahdi M, Sopandie D, Trikoesoemaningtyas, Sulistyono E, Azrai M. 2022. Secondary trait and index selection determination for maize genotype selection in acidic tidal swamp environment. Biodiversitas 23: 4169-4179. Determining secondary traits as complementary selection in maize genotypes for abiotic stress environment is compulsory since yield-based selection usually provides biased result. This study aimed to obtain secondary traits for maize selection in an abiotic multi-stresses of Fe, Al, and temporary flooding environments of acid sulfate tidal swamp land using multivariate analysis. A total of 150 (un-repeated) maize inbred lines and five check genotypes in five replicates were arranged in a randomized augmented plot design in three environments to generate 525 single plots. Three types of environments based on irrigation regimes were applied on acid soil tidal swamp land to study the agronomic characteristics of maize genotypes in each environment. Saturated Cultivation Technology (SSC) was considered the optimal environment. Dryland treatment was the condition to let the irrigation only depend on rainwater. Temporary flooding treatment was carried out at five stages of different growth periods. Several steps of analysis were applied in this study by taking variance, and heritability was used as the basis for selections. The characters affected by treatments with medium to high heritability were then analyzed with correlation and pathway analysis. Seven selection indexes, SSI, GMP, YSI, YI, TOL, STI, and MP, that have a high correlation to yield in both optimum and stress environments, were applied simultaneity with the selected trait characters to screen the genotypes utilizing PCA biplot analysis. Venn analysis was used to group the genotypes based on the result of the analysis. Indices of STI, MP, GMP, and traits of rows number per ear and the weight of 6 ears were selected as secondary characters for the maize genotypes selection in Saturated Soil culture with temporary flooding stress. Meanwhile, STI, MP, and ear stand height were the selected characters in the dryland of acid sulfate tidal swamp land. Based on the combination of all secondary character selection, genotypes were grouped into five types of stress tolerance in SSC+TF and DL environments. Eight genotypes were tolerant to both SSC+TF and DL stress, and two genotypes were susceptible to both environments.
