Results of the t test for paired sample analysis, showed significant (P < 0.05 and P < 0.001) difference between mean value of observed and simulated maize grain yields in Dogbo and Dassa during both growing seasons (2011 and 2012). Maize grows best on deep, well-drained, fertile soils, and where total seasonal rainfall exceeds 500 mm.

In the cropping season 2012, the N–P–K fertilizer rates studied showed significant effect on both grain and stover yields compared to the control. 103. The way forward is to rerun the model considering different maize cultivars with different growing cycles, combining organic manure with different rates of mineral fertilizer and strategies to improve crop water use efficiency. Cultivation of paddocks which have been in long-term pasture can result in the release of up to 300 kgN/ha from soil organic matter.

This economic strategic analysis for the past 32 years showed that fertilizer rates 80–30–25, 80–15–40 and 80–30–0 respectively for the sites of Dogbo, Allada and Dassa, were the economically superior fertilizer recommendations as they presented the highest return to investment per hectare and the highest efficiency.

Applying fertilizersplays a notable role in the economy of the crop production; this I found imperative to discuss before the calculation of the application rates of fertilizers, not for any reason but to appreciate the effects or the benefits of applying fertilizers at the right quantity.

In general, it was observed from the field data that, maize grain yields are related to the variation of the N rates. The model has slightly underestimated maize grain yields at Dassa (growing season of 2011) and Dogbo (growing season of 2012) while data predicted by the model fit well with that of Allada during the growing season of 2012 (Table 4). Using a product such as SingleTop 27-0-0(12SO 3 ) at a rate of 200kg/ha is ideal, supplying 54kg N/ha and 24kg SO 3 /ha. N–P–K fertilizer microdosing increased maize yields by 99% in the humid forest zone.

Correspondence to 1, it is also observed that at 75% cumulative probability, at Dogbo, the maximum average maize grain yields of 750, 1750, 2300 and 2500 kg ha−1 were obtained when respectively 0–0–0, 46–15–25, 69–30–40 and 80–30–40 fertilizer rates, were applied. Farmers do not generally follow the national fertilizer recommendation rates (for instance, the application of 100 DAP + 100 urea kg ha −1 at planting and jointing, respectively, for maize), due to high fertilizer cost, fertilizer supply shortages and insufficient training in fertilizer use [ 2, 4, 22 ]. In consideration, choice of model-based stochastic approaches combined with economic analyses have been made in the present study. FAO/World Bank. Fertilizer recommendations for maize production in the South Sudan and Sudano-Guinean zones of Benin. The first factor was maize cultivar (Bisi 2 and Pioneer 35). The maize plant heights were significantly greater with the treatments that received a micro-dose of NPK 2:3:2(34) fertilizer in both first and second seasons by 42.2% and 89.5%, respectively. Our results suggest that for intensive maize cultivation the most economically superior N–P–K fertilizer rates are 80–30–25 and 80–15–40 (respectively for Acrisols of Dogbo and Allada in the south) and 80–30–25 (for Ferric and Plintic Luvisols of the Centre). In the case of intensive maize cultivation, N–P–K options 80–30–25 and 80–15–40 (for Acrisols) and 80–30–0 including crop residue management (for Ferric and Plintic Luvisols) were the most economic and efficient fertilizer rates that gave maximum return to investment for farmers. Fertilizer rates 80–30–25, 80–15–40 and 80–30–0 presented the best return to investment per hectare and the best efficiency. The fertilizer dose 80–30–0 generated by the model suggested no application of K at the Dassa site which is not sustainable as it will contribute to K mining in these soils (the quantity of K taken up by the plant is not returned to the soil). This is to ensure that we give you the best experience possible. Microdosing increased N, P, and K use efficiency of maize in rotation vs. sole cropping. Article  Agron Afr 22(1):55–63, Loague K, Green RE (1991) Statistical and graphical methods for evaluating solute transport models: overview and application. Part of Springer Nature. The standard fertilizer recommendation for maize consists of 150 kg ha −1 NPK 14–23–14 and 50 kg ha −1 urea (Dugué 2010). Always keep the maize farm without weeds until it flowers. In general, the observed maize grain and stover yields of the different N–P–K combinations, except for the fertilizer rate 46–15–25 (in 2011), were significantly different compared to the standard fertilizer recommendation (44–15–17.5) at Dogbo (Table 2). Despite that the Dogbo and Allada sites are located in the same soil type, almost twice the amount of P was suggested for the Dogbo site while for Allada site the model suggested an additional application of K. These results reflected land use types which considerably affect fertilizer use efficiency in the farmers’ fields (Saïdou et al. Apply 150: 75: 75 kg N, P2O5 and K2O/ha Other nutrient management practice are same as in the case of Maize varieties. To avoid this long-term unsustainable option the fertilizer rate 80–30–25 (with a net return to investment per hectare of FCFA 309708.7 against 315,749.6 for fertilizer rate 80–30–0) would be economically sound and viable for soil fertility management. What do I use to fertilize my maize: Liquids or granules? These authors also found that nitrogen is the most limiting nutrient for cereal production in the Sub-Saharan Africa’s soils. This N–P–K option should be followed by proper crop residue management and organic manure supply.
