From: Effect of slow-release nitrogenous fertilizers on dry matter accumulation, grain nutritional quality, water productivity and wheat yield under an arid environment

Figure 3The alternative text for this image may have been generated using AI.

Correlation of various soil nutrients with yield, crop index (%), irrigation water use efficiency (kg ha−1 mm−1) at various N rates and slow release fertilizers. The circle’s areas depict the absolute result of corresponding correlation coefficients tested at *0.01 significance level. Light and dark blue colors depicted the minimum and maximum values. Star (*) and non-star presented significance and non-significance. GY grain yield, TDM total dry matter, Grain N grain nitrogen, Grain P grain phosphorus, Grain K grain potassium, Irrigation WUE irrigation water use efficiency, DMAA dry matter accumulation after anthesis, CDMAA contribution of dry matter accumulation after anthesis to wheat grains.
