“…Studies done so far on soybean in Ethiopia have focused on rhizobial inoculation response, genetic variability of soybean for agronomic traits, and intercropping trials with cereals (Bekere et al 2013 ; Dilnesaw and Getahun 2013 ; Zerihun et al 2014 ; Jaiswal et al 2016 ). Little information currently exists on i) the presence or absence of effective native soybean rhizobia in Ethiopian soils, ii) the response of different soybean genotypes to nodulation and N 2 fixation by indigenous rhizobia in Ethiopia, and iii) the distribution of rhizobia in Ethiopian soils.…”

Achieving food and nutritional security is a major challenge in Ethiopia, especially with increasing human population and low crop productivity. Legumes offer an alternative choice to chemical fertilizers for increasing crop yields. The aim of this study was to assess, under glasshouse conditions, plant growth and symbiotic performance of uninoculated soybean genotypes planted in soils collected from different locations in Ethiopia. The results showed significant differences in plant growth and symbiotic performance among the soybean genotypes planted in different soils. There was a location-specific effect of soil on plant growth and symbiotic N nutrition of soybean. Whole-plant biomass was highest in soil from Amaro, followed by Boricha, Dorebafano, Pawe, and Mambuk. The δ15N values ranged from +0.82‰ for Pawe to +5.11‰ at Dorebafano. However, %Ndfa of soybean was greater in plants grown in Mambuk soil, followed by Pawe with the lowest %Ndfa being in Amaro soil. The amount of N-fixed followed similar pattern as %Ndfa. The significant interaction found between soil type and soybean genotype for plant DM, shoot N concentration, δ15N, %Ndfa, N-fixed and soil N-uptake clearly indicated the effect of soil factors. This study revealed the presence of native rhizobia in Ethiopian soils that are compatible with soybean. The N contribution of the soybean genotypes was variable, and strongly influenced by the soil factors.

Tanaman Jagung dan kedelay termasuk tanaman pangan penting setelah padi dan gandum namun kendala yang dihadapi dalam budidaya tanaman tersebut secara monokultur adalah keterbatasan lahan serta kesuburan tanah. Penelitian ini bertujuan untuk mengkaji sistem pertanaman dan peran residu tanaman jagung dan kedelai serta biocharnya terhadap simpanan C-organik tanah, bobot isi tanah, beberapa sifat kimia tanah dan nisbah kesetraan lahan. Penelitian ini dilaksanakan di kebun sains Sidondo BPTP Sulawesi Tengah dan laboratorium tanah Universitas Tadulako Palu Sulawesi Tengah. Percobaan disusun berdasarkan rancangan acak kelompok faktorial 5x5 pola petak terbagi (Split Plot Design) dengan tiga ulangan. Sebagai petak utama adalah system pertanaman yaitu; (T1) monokultur jagung, (T2) monokultur kedelai, (T3) tumpangsari jagung/kedelai (1:1), (T4) tumpangsari jagung/kedelai (2:1), (T5) dan tumpangsari jagung/kedelai (2:4). Anak Petak yaitu residu dan biochar jagung-kedelai yang diberi label (R1) tanpa residu, (R2) residu jagung, (R3) residu kedelai, (R4) residu jagung+kedelai, (R5) biochar jagung+kedelai. Setiap ulangan (blok) memiliki 25 plot, masing-masing berukuran 3,5 m x 4,5 m. Hasil penelitian menunjukkan simpanan C-organik dan C oraganik tanah tertinggi pada interaksi perakuan tumpangsari 2:4 dengan biochar, Bobot isi tanah terendah pada interaksi perlakuan monokultur kedalai dengan biochar, N Total tertinggi pada interaksi perlakuan tumpangsari 2:4 dengan residu jagung kedelai. P Total pada interaksi perlakuan tumpangsari 2:4 dengan biochar, K total tertinggi pada interaksi perlakuan tumpangsari 1:2 dengan Residu jagung kedelai, nisbah kesetraan lahan tertinggi pada interaksi perlakuan tumpangsari 2:4 dengan residu kedelai.

“…Study by Abebe et al, (2014) reported the variation in genotypes for yield across the year. In addition, environmental variation and even management differences may cause the yield and yield trait variations(Abebe et al, 2014). According to Wiatrak (2012), unfavourable environmental conditions such as high temperature disturb soybean growth, development and yield.…”

The study was conducted using sixteen soybean varieties gained from Pawe Agricultural Research Center. The varieties were tested for yield and yield-related traits at Arbaminch zuria district during the 2017 and 2018 main production periods. The study was conducted by using a randomized complete block design with three replications. Variance analysis for the individual year on yield and yield component showed significant differences (p<0.05) among genotypes except for seeds per pod in the year 2018. During the 2017 cropping season, the highest yield was obtained from Gazale (1948 kgha-1) and Niyala (1922 kgha-1 whereas the lowest grain yield was obtained from AFGAT (956 kgh-1). While in 2018 Nova (1110 kgha-1), Dhedessaa (1050.9kgha-1) and Nyala (988.9 kgha-1) showed better yield than other tested varieties while the lowest grain yield was observed on Korme (504.6 kgh-1). The combined test for analysis of variance showed a significant differences among genotypes for grain yield and components of yeild exculding the number of seeds per pod. The highest plant height was recorded for AFGAT (107.7m) whereas the highest number of pods per plant was obtained from Jalale (61.03) followed by Dhedessaa (60.23). The maximum hundred seed weight was gained from Nyala (15.67g while the highest branch number was obtained from Jalale (4.2) and Gishima (4.1). Nyala and Gazale had the highest grain yield of 1455 kgha-1 and 1445 kgha-1, respectively, while AFGAT (819Kgha-1 had the lowest grain yield. The result obtained from Niyala (1455 kgh-1) and Gazale (1445kgh-1) gave better yields than other tested varieties. Therefore, varieties Nyala and Gazale can be recommended for the study area and areas with similar agro-ecologies for demonstration.
