Optimal yield and quality of wheat (Triticum aestivum L.) depend to a large extent on the rate of nitrogen (N) fertilizer application, which may often be inadequate. Uptake and utilization of N by wheat plants are influenced by environment and variety, and consequently supplementary N may be needed during the growing season according to variations in these factors. Additional N can be applied at specific stages of plant development (phenology) for maximum effect. However, timing supplemental N application according to growth stage scales may not result in maximum yield as the scales do not provide sufficiently precise indication of spikelet and floret formation, which critically affect the sink capacity of the plant. In this review it is proposed that knowledge of apical development offers a means to identify the initiation and formation of those plant organs that are indicators of specific stages of plant development. Aspects of the general usage of apical development stages in timing N, and how they vary according to growing conditions, are discussed. |
