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

Figure 3

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.
