Maize is reasonably tolerant to soil acidity, but if the soil is very acid, liming will improve the soil and enhance maize yields. Fertilizer micro‐dosing at planting improves the agronomic performance of maize by improving seedling uniformity and vigor, shortening days to maturity and harvest, and higher yields.

CAB International, Wallingford, pp 155–171, He J, Porter C, Wilkens P, Marin F, Hu H, Jones JW (2010) Guidelines for installing and running GLUE program. The main characteristic of both soils is their low organic matter level which was also mentioned by several studies (Sanchez et al. Furthermore, it was noticed that, the observed maize grain yields were highly correlated with estimated values by the model. Moving to early varieties which deliver high quality feed will allow farmers to exploit advances in maize breeding. Fertilizer application does not improve emergence and percent seed germination. Maize Fertilizer Requirements Per Acre. Fertilizer application significantly (p < 0.001) increased maize yield by 1.12 t ha −1 with micro-dosing and by 1.60 t ha −1 with recommended rates over the control. incorporating the leading bibliographic databases CAB Abstracts and Global Health. The lowest values were found on the control field while the highest with 80–30–25, 92–30–40 and 80–15–40 at Dogbo, Allada and Dassa respectively. 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). Data simulated by DSSAT-CERES model were compared with the real data obtained in 2011 and 2012 in the field, in order to determine the suitability of making site specific fertilizer recommendations. N–P–K fertilizer microdosing increased maize yields by 99% in the humid forest zone. (2001). The amount of fertilizer required is best calculated by multiplying the target yield in tons per hectare, by 20-25 Kg. So, the fertilizer dose between 120 and 160 kg ha–1is the optimum recommended dose. This shows the importance of the supply of N and P to improve maize production in this part of Africa. 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 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.

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 ]. 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). 4.

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. Nutr Cycl Agroecosyst 110, 361–373 (2018). These N–P–K fertilizer rates are far from current standard fertilizer recommendations and do not allow a maize crop to satisfy its nutrient requirements.

The net harvested plot area was 7.2 m 2 (5 rows 3 m long).The recommended dose of phosphorous @ 60 kg/ha, potassium @ 40 kg/ha and poultry manure @ 5 t/ha were applied as basal in all experimental plots. 1. Apart from the control plot, maize yields predicted were very good (R2 values more or less close to 100%) compared to the field results. 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).

Furthermore, one can also consider that the DSSAT model has been rational in the economy of N utilisation by suggesting a reduced quantity. This can be explained by the fact that the version 4.5 of DSSAT model is not sensitive to the rates of K during the simulation process. Fertilizer Requirement. Like most websites we use cookies.
