“…Similar increases in grain yield with increasing plant population have also been reported in soybean (Quayum, 1983;Chiezey et al, 1991;Toungos et al, 2009) and in cowpea (Ndor et al, 2012). The 100-seed weight was not influenced by plant population.…”

Responses of bambara groundnut (Vigna subterranea (L.) Verdc) to 3 levels of fertilizer N (0, 50, and 100 kg N/ha) and seven plant populations (55555, 63492, 74074, 88888, 111111, 148148 and 222222 plants/ha) were studied under field conditions in Nsukka, Nigeria. The experimental design was a randomized complete block and there were three replications. Seed yield progressively increased with increasing plant population, being significantly highest at 222,222 plants/ha. The application of 100 kg N/ha increased the total dry matter per plant compared with no application or with 50 kg N/ha, although seed yield benefits were not readily apparent. Nodulation was not statistically influenced by N treatment although zero or-low N application showed a slight increase in nodulation, suggesting a lack of adequate population of the effective rhizobium in the location. Innoculation of bambara groundnut seeds with effective rhizobium strain before planting becomes necessary for good nodulation and production of the crop under Nsukka agro-ecological conditions.

“…Such conditioning of the soil due to biochar application is expected to also improve soil physical condition, encourage prolific root growth and enhance air, water and gas transport. Furthermore, ameliorative effect of biochar will also enhance microbial population, increase concentrations of active soil organic matter, influence carbon and nitrogen cycling and also stimulate soil enzyme activities which influence crop growth environment (Revell et al 2012;Ndor et al 2015;Yao et al 2017). Recent studies by Mete et al (2015) and Faloye et al (2017) have also observed an increased crop yield when biochar and mineral fertilizers were combined.…”

Purpose Biochar and inorganic fertilizer when co-applied have been reported to increase crop yield and enhance soil fertility. However, studies on this complementary effect on soil properties and rain-fed upland rice performance in Sub-Saharan Africa are still scanty. Methods Field factorial studies conducted over 2 years was set up to investigate the interactions between rice husk biochar and inorganic nitrogen (N) fertilizer on a sandy clay loam Alfisol. A two-factor (4 × 4) in RCBD where rice husk biochar was incorporated at four doses, 0, 3, 6, and 12 t/ha −1 , inorganic N fertilizer (urea) at four rates, 0, 30, 60 and 90 N kg/ha −1 , and their combinations was adopted. Results Results showed that combination of biochar and N fertilizer exerted significant (P > 0.05) interactive effect on rice harvest index, grain and straw yield and N-use efficiency. Interaction between biochar and N fertilizer increased agronomic efficiency by 140% and grain nutrient recovery by 191% over 2 years. Combination of biochar and N fertilizer reduced soil bulk density, increased water holding capacity and soil chemical status such as pH, N, P, K, Corg, Ca, ECEC and base saturation, all within the top 10 cm depth of the soil. Conclusions Overall, the results established that rice husk biochar can be used as a soil conditioner to enhance upland rice yield on an Alfisol. The combined dose of 3-6 t/ha −1 biochar and 30 kg/ha −1 of N fertilizer is thus recommended for upland rice farmers in the study area.

“…Biochar at 20 t/ha incorporated into the top 0.2 m and was evenly and manually mixed with the soil at the experimental site. These low application rates were considered appropriate for improving maize yield in nutrient degraded soils based on the report of previous studies (Major et al 2010;Uzoma et al 2011;Ndor et al 2015).…”

The individual and combined effects of biochar (B) and inorganic fertiliser (F) have all been widely proofed to improve soil fertility and enhance crop growth and yield under irrigation (I) and rain fed conditions. However, the strength of their individual and combined effects on crop productivity has been scarcely reported. In addition, few studies have assessed their individual and co-application effects on economic returns. Therefore, a 2-year field experiment which consisted of factorial combination of irrigation (I) [100% full irrigation (FI), 80% FI and 60% FI], biochar (0 and 20 t/ha) and fertiliser (0 and 300 kg/ha) was conducted. According to the results, irrigation was the dominant factor that influences maize grain yield, followed by inorganic fertiliser and biochar, and they were all significant in their main effects. The strength of interaction effects among, I, F and B on maize grain yield follow the sequence F × I > B × F > B × I. The economic analysis showed that the ternary combination of B, F and I was more economical than the binary combination of B plus I, and F plus I (in that order), when compared with the standalone application of I at maximum production in the field experiment. In addition, combined applications of biochar and fertiliser improved soil nutrients, nutrient uptake in all irrigation treatments, compared to the standalone applications of biochar or fertiliser. Further research is, therefore, recommended for long-term evaluation of the economic viability of integrating biochar with fertiliser under irrigation.
