“…During the past decade, several initiatives including the use of high yielding varieties, phosphate-based fertilizers, and inoculants have been introduced to farmers in the three northern regions of Ghana to improve the productivity of grain legumes (Ahiabor et al, 2014;Aziz et al, 2016). While these initiatives are being promoted by research and extension and other projects, their economic viability has not been assessed under farmers' field conditions.…”

The dry haulms after harvest and the husk after threshing the pods are an excellent source of livestock feed for ruminants, particularly in the northern Guinea Savanna zone.Cowpea (Vigna unguiculata L. Walp), peanut (Arachis hypogea L.), and soybean (Glycine max L.) are the three most important grain legumes in West Africa, where they form major components of the predominantly cereal-based farming systems. The Food and Agriculture Organization (FAO) estimates for the 2014 world total area under cultivation of these three legumes was 12.6 million, 26.5 million, and 118 million ha for cowpea, peanut, and soybean, respectively. The world total production of these crops for the same period was about 5.6 million, 43.9 million, and 300 million tons annually for cowpea, peanut, and soybean, respectively. While ~85 and ~23% of the total world production of cowpea and peanut is estimated at 4.5 and 6.5 million tons, respectively, for cowpea and peanut occurs in West Africa, only about 0.26% of the world's total soybean production occurs in West Africa (FAO, 2014b). These crops are

“…As an important economic crop, soybean is a main source of edible oil and protein for human around the world due to the high oil (20–25%) and high protein (42–45%) contents in the seeds (Aziz et al, 2016). At the same time, the high capacity of biological nitrogen fixation (BNF) found in leguminous crops, including soybean, makes this a key source of green manure in agro-ecosystems (Kumudini et al, 2008; Chen and Liao, 2017; Yang et al, 2017).…”

Soybean is an important economic and green manure crop that is widely used in intercropping and rotation systems due to its high biological nitrogen fixation (BNF) capacity and the resulting reduction in N fertilization. However, the genetic mechanisms underlying soybean BNF are largely unknown. Here, two soybean parent genotypes contrasting in BNF traits and 168 F9:11 recombinant inbred lines (RILs) were evaluated under four conditions in the field. The parent FC1 always produced more big nodules, yet fewer nodules in total than the parent FC2 in the field. Furthermore, nodulation in FC1 was more responsive to environmental changes than that in FC2. Broad-sense heritability (h2b) for all BNF traits varied from 0.48 to 0.87, which suggests that variation in the observed BNF traits was primarily determined by genotype. Moreover, two new QTLs for BNF traits, qBNF-16 and qBNF-17, were identified in this study. The qBNF-16 locus was detected under all of the four tested conditions, where it explained 15.9–59.0% of phenotypic variation with LOD values of 6.31–32.5. Meanwhile qBNF-17 explained 12.6–18.6% of observed variation with LOD values of 4.93–7.51. Genotype group analysis indicated that the FC1 genotype of qBNF-16 primarily affected nodule size (NS), while the FC2 genotype of qBNF-16 promoted nodule number (NN). On the other hand, the FC1 genotype of qBNF-17 influenced NN and the FC2 genotype of qBNF-17 impacted NS. The results on the whole suggest that these two QTLs might be valuable markers for breeding elite soybean varieties with high BNF capacities.

“…Aziz et al (2016) reported that the use of P2O5 fertilizer at 49 kg ha -1 did not cause significant difference in plant height compared with the plants without any fertilizers. The substitution of compound Phonska with single fertilizer with various doses also did not affect the height and diameter of stem.…”

The efforts to improve the productivity of soybean can be done through technological innovation by the provision of chemical fertilizers and mycorrhizae. This study were aimed to obtain information on the effect of a single fertilizer, which can provide the same or higher level of soybean crops if compared with those compound fertilizers, as well as to find out the effect of mycorrhizae to the improvement of efficiency in the use of inorganic fertilizers. It is expected that the mycorrhizae inoculation can reduce single fertilizer's dose to the level equivalent to the compound fertilizer given by farmers. The study was conducted in Bleberan Village, Playen Subdistrict, Gunung Kidul Regency, Yogyakarta from February to May 2015. It was conducted by using a two-factors factorial design arranged in a randomized block design with three replications. The first factor was inorganic fertilizer (N, P2O5 and K2O), consisting of 5 levels, i.e. without fertilizer (0-0-0 kg ha ). The second factor was mycorrhizal inoculation, consisting of three levels, i.e. without mycorrhizae (0 g), medium dose (2.5 g) and high dose (5 g). Data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. If there was a significant difference, analysis was followed by Duncan Multiple Range Test with a significance level of 5%. The relationship between variables observed was examined by a correlation analysis. The results showed that there was no interaction between inorganic fertilizer and mycorrhizal application. The dose of single fertilizer which was equivalent to the dose of compound fertilizer given to soybean could increase crops by 1.37 t ha -1 compared with plants treated with a compound fertilizer 1.13 t ha - 1. The results of correlation analysis among parameters showed that there were correlations between the grain crops and height (r = 0.506**), stem diameter (r = 0.303*), and the number of pods per plant (r = 0.313*).
