Summary
The interrelations between nitrogen and water supply on the growth and yield of wheat (Triticum aestivum L.) were studied with particular attention to water use and grain yield in relation to the time of application of nitrogen to the plants. Nitrogen was applied at seeding or deferred until the double ridge-stage of development. Effects of both soil-applied and foliar-applied nitrogen were investigated under deficient or adequate water supply. The supply of water to the crop controlled the level of yield obtained and the response of the crop to applied N was markedly greater in drought-free conditions. Application of N resulted in increases in both crop leaf area duration and water use. Greater responses to N were obtained when the fertilizer was applied to the soil, rather than as a foliar spray.
