The crops currently cultivated in Nigeria include mostly yams and cassava and limited amounts of irrigated rice in east Niger (central Nigeria) to Taraba and Crossriver statesalong the border of Cameroon. In the southernmost states, where the seasonreaches a length of ten months, a second maize crop can be produced. Both riceand the secondary late maize (in terms of area and output) have been harvested inJanuary and the maps in this section thus cover their final stages. The mainmaize crop was harvested just before the current reporting period started.According to the CropWatch environmental indices, the current period ischaracterized by an unusual combination of both above average rainfall andradiation resulting in a national biomass accumulation almost 10 percent abovethe average of the recent decade, but below the average of the last five years.Current national NDVI values are close to the seasonal average, recovering frombelow average four months ago. NDVI profiles are usually about averageeverywhere (including in rice growing areas), but above average in largereaches of the south, pointing at favorable conditions of the second maizecrop. Fluctuating conditions occurred mostly in the southern areas around OyoState (west) but are unlikely to have affected crops. Biomass accumulationpoints at unfavorable growth in the eastern rice growing areas, but confirmsthe favorable situation for the second maize crop.
