Effect of Potassium and Nitrogen on the Growth and Chemical Composition of Wheat Grown in Some Rajasthan Soils

The effect of potassium and nitrogen was studied on the growth and chemical composition of wheat grown on eight representative Rajasthan soils. In general, the percentage crop response was higher due to nitrogen than to potassium and potassium-nitrogen interaction was not significant in most of the soils. Chemical composition of the plant showed that absorption of nitrogen increased with its application but was suppressed by Potassium. Potassium uptake increased with the addition of potash and more so in combination with nitrogen.
