CAB Direct Whilst maize requires Sulphur in modest amounts, it can be beneficial. The maize grain and the stover yields simulated by DSSAT model fit well with data observed in the field during the two growing seasons (2011 and 2012) for all of the experimental sites. 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 ].

The consequence of this high C/N ratio is a low level of total N which seems to be with P the most limiting nutrients. It is a measure of the spread of a probability distribution. 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. ) the Gini coefficient of distributions A and B. F is half the value of Gini’s mean difference. But considering the Gini coefficient, the net return to investment per hectare calculated for N–P–K fertilizer dose 80–30–25 is sound as far as K application is concerned. In: Payne WA, Keeney DR, Rao SC (eds) Sustainability of agricultural systems in transition. The first factor was maize cultivar (Bisi 2 and Pioneer 35). During this growing season, no significant differences were noticed among the N–P–K fertilizer rates but all the treatments had significantly increased yields by a factor of 1.5–2 respectively compared to control (0–0–0). CAB Direct provides In general, it was observed from the field data that, maize grain yields are related to the variation of the N rates.

Developments in maize breeding offer significant advantages from both nutritional and environmental perspectives, allowing farmers to increase production from forage and the return on their investment in maize. 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. Apply the fertilizer when the soil is moist. Maize is reasonably tolerant to soil acidity, but if the soil is very acid, liming will improve the soil and enhance maize yields.

However, From Fig. It is observed that after 160 kg ha–1N application, the marginal yield becomes negative i.e. 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).

The results revealed that HO-3 produced the highest yield components and a significant (p < 0.05) yield (8,276.69 kg ha-1), representing an increase of (50 %) over the control.

The lack of difference in maize grain yields found between fertilizer rates 80–30–40, 80–15–40, 80–30–25 and 80–30–0 suggested that whatever the rate of P and K, the simulated net returns per hectare were similar when N rate does not vary. 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).
