Background: The productivity of soybean in Assosa Zone particularly in Assosa and Bambassi districts is very low due to poor soil fertility management practices which resulted in severe soil acidity and low N-fixing inoculant in the soil. Hence, this experiment was conducted to evaluate the influence of biofertilizer and inorganic fertilizers on nodulation, growth and yield of soybean [Glycine max (L.) Merrill]. Methods: During the period 2019-2020 factorial combinations of four levels of biofertilizer inoculants [without inoculant (B1), SB12 inoculant (B2), MAR1495 inoculant (B3) and SB12 plus MAR1495 inoculants (B4); and four inorganic fertilizer types NP (F1), NPS (F2), NPB (F3) and NPSB (F4) at their recommended rates for soybean] were laid out in a randomized complete block design (RCBD) with three replications in Assosa and Bambassi districts, Assosa Zone, Western Ethiopia. Number of effective nodules per plant, leaf area index and grain yield were collected following the standard procedures and were analyzed using SAS software version 9.1.3 and significant mean differences were separated using Duncan’s multiple range test (DMRT) at 5% significance level. Result: Number of effective nodules per plant, leaf area index and grain yield were highly significantly (P less than 0.01) affected by the interactions of biofertilizer and inorganic fertilizers at both locations and years. Thus, the maximum grain yield (2621.67 kg) was obtained from (SB12+MAR1495) + NPSB at Assosa and the maximum grain yield (2460.20 kg) was obtained from SB12+NPS at Bambassi. Hence, (SB12+MAR1495) + NPSB and SB12+NPS are recommended for higher soybean grain yield for Assosa and Bambassi districts and similar agro-ecologies, respectively.

Glycine Max L

An experiment was conducted at saline agro-ecosystem of Burir Char Union, Barguna District during January to June 2018, with a view to find out  the fertilizer management for maximizing soybean (Glycine max L.) production in saline agro-ecosystem was laid out in randomized complete block design consisted of three varieties of soybean and four levels of fertilizer doses with three replications. Three varieties of soybean viz. BARI Soybean-5, BARI Soybean-6 and Binasoybean-3 and  four fertilizer levels viz. T1 = 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer); T2 = 30-40-60-12-2.0-1.0 kgha-1 N-P-K-S-Zn-B (Fertilizer recommendation guide, 2012); T3 = 40-20-15-0-0-0 kgha-1 N-P-K-S-Zn-B (Farmers practices); T4 = Control native fertility were considered  which placed in a factorial randomized block design. The variety had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, seed yield (t ha-1), stover yield (t ha-1). BARI Soybean-6 performed better than the other two varieties. The fertilizer doses had significant influence on plant height, branches plant-1, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, 100-seed weight, seed yield (t ha-1), stover yield (t ha-1). Fertilizer doses 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B (Soil test based fertilizer) gave the maximum yield. The interaction between variety and fertilizer doses V2T1 (BARI Soybean-6 and 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B) produced the maximum yield SO, the variety BARI Soybean-6  with  fertilizer dose 25-30-45-10-1.0-1.0 kgha-1 N-P-K-S-Zn-B could be suitable combination for higher yield of soybean in saline agro ecosystem of Barguna.
