“…However, beyond the optimum nitrogen fertilizer application rate, additional nitrogen input demonstrated adverse effects on soils with potential to negatively affect crop productivity in the long-term. The increase in soil nitrogen likely enhanced soil nutrient balance, which probably increased the availability and uptake of other essential nutrients that improved maize yield [6]. Generally, the increased maize yield with increasing nitrogen input supports the hypothesis of this study that higher nitrogen fertilizer rates will enhance maize yield.…”

“…Poor and declining soil fertility is a major challenge for crop production in SSA, with nitrogen (N) and phosphorus (P) as the most limiting elements [4,5]. Nitrogen mediates uptake and utilization of other nutrients and contributes to maize growth and yield [6]. Nitrogen fertilizers are commonly used to improve soil fertility and plant nutrition, but nitrogen inputs can only increase maize yield up to a maximum rate for any particular site based on soil and climatic conditions [7][8][9].…”

Nitrogen (N) fertilizer is commonly used to improve soil fertility and maize production in Cameroon, but high cost and potential environmental effects have necessitated site-specific N fertilization regimes that are adapted to particular soil and crop types. A field experiment was conducted with five N application rates (control–0, 50, 100, 150, and 200 kg N ha−1) to determine optimum rate for best maize yield with limited effect on soil acidification. The soil residual N ranged from 0.18 to 0.36% across N application rates and increased at higher application rates with the highest in 150 and 200 kg N ha−1. Soil C/N ratio ranged from 7.5 to 15.5 across N rates with the highest in control, which decreased at higher N application rates. Soil pH ranged from 4.7 to 5.4 across N rates, with the lowest in 200 kg N ha−1 rate. Maize grain yield and cob length ranged from 7.1 to 10.3 t ha−1 and from 14.5 to 18 cm across N rates, respectively, with the highest in 150 and 200 kg N ha−1. Maize 1000-grain weight ranged from 380 to 560 g across N application rates with the highest in 100, 150, and 200 kg N ha−1. Significant negative correlations occurred between soil pH and maize yield or 1000-grain weight. Maize N use efficiency decreased sharply at higher N application rates, as demonstrated by a strong negative correlation between the N-Partial Factor Productivity and total soil N. Overall, the lower soil pH at higher N application rates highlights the potential for deleterious effects of N fertilizer inputs on arable soils, which may eventually affect crop productivity, thereby suggesting lower N fertilization regimes between 50 and 100 kg N ha−1 as the optimum for maize production on the volcanic soils of Buea.

Intensification of maize/legume production during early rains in the High Rainforest region of South Southern Nigeria is limited by heavy rainfall. Production of late season maize/legume by peasant farmers is gaining prominence though yields are low due to low soil fertility and improper crop arrangement. The objective of this research was to investigate the yield performance of late season maize/soybean intercropping in response to nitrogen fertilization and spatial arrangement of the intercrops. The trial was a split-plot design in randomized complete block with three replications. Treatments consisted of five rates of nitrogen (0,

“…Thereby, N is the motor of plant growth and makes up 1 to 4% of dry matter of the plants (Taiz and Zeiger, 2010). It also mediates the utilization of P, K, and other elements in plants (Onasanya et al, 2009). It is widely accepted that crops grown on soils deficient in N, exhibit very distinctive N deficiency symptoms such as poor growth, chlorosis, necrosis and causes disorder in many physiological/biochemical characteristics of plants (Taiz and Zeiger, 2010).…”

and Uttar Pradesh (Anon., 2018). Recent studies have shown that maize can be successfully grown during Rabi in many parts of the country due to evolution of new genotypes. In India, maize has been widely cultivated as a rainfed crop during kharif season but it is also being successfully grown during Rabi under irrigated conditions with higher productivity due to its timely water availability and higher fertilizer use efficiencies Patel et al., (2006).
