"The use of crop models is motivated by the prediction of crop production under climate\r\nchange and for the evaluation of climate risk adaptation strategies. Therefore, in the present\r\nstudy the performance of DSSAT 4.6 was evaluated in a cropping system involving integrated\r\nsoil fertility management options that are being promoted as ways of adapting agricultural\r\nsystems to improve both crop yield and carbon sequestration on highly degraded soils\r\nencountered throughout middle Côte d’Ivoire. Experimental data encompassed two seasons\r\nin the Guinea savanna zone. Residues from the preceding vegetation were left to dry on plots\r\nlike mulch on an experimental design that comprised the following treatments: (i) herbaceous\r\nsavanna-maize, (ii)10 year-old of the shrub Chromolaena odorata fallow-maize (iii) 1 or 2\r\nyear-old Lalab pupureus stand-rotation, (iv) the legume L. pupureus -maize rotation; (v) continuous\r\nmaize crop fertilized with urea; (vi) continuous maize crop fertilized with triple superphosphate;\r\n(vii) continuous maize crop, fertilized with both urea and triple superphosphate\r\n(TSP); (viii) continuous maize cultivation. The model’s sensitivity analysis was run to figure\r\nout how uncertainty of stable organic carbon (SOM3) can generate variation in the prediction\r\nof soil organic carbon (SOC) dynamics during the monitoring period of two years, within\r\nthe first soil layer and to estimate the most suitable value. The observed variations were of\r\n0.05 % in total SOC within the short-term and acceptable dynamics of changes were obtained\r\nfor 0.80% of SOM3. The DSSAT model was calibrated using data from the 2007-2008\r\nseason and validated against independent data sets of yield of 2008-2009 to 2011-2012\r\ncropping seasons. After the default values for SOM3 used in the model was substituted by the\r\nestimated one from sensitivity analysis, the model predicted average maize yields of 1 454\r\nkg ha-1 across the sites versus an observed average value of 1 736 kg ha-1, R2 of 0.72\r\nand RMSE of 597 kg ha-1. The impact of fallow residues and cropping sequence on maize\r\nyield was simulated and compared to conventional fertilizer and control data using historical\r\nclimate scenarios over 12 years. Improving soil fertility through conservation agriculture cannot\r\nmaintain grain yield in the same way as conventional urea inputs, although there is better\r\nyield stability against high climate variability according to our results."^^ .
