sand culture experiment conducted in sweet potato with five levels each of phosphorus and potassium to induce deficiency symptoms revealed the typical P deficiency symptom as purple and yellow discolouration of leaf lamina followed by leaf abcission in almost all the leaves except in the newly emerged leaves. These symptoms started appearing when P concentration in the leaf tissue was 0.04-0.07 percent. Fishbone symptom was the typical of K deficiency and tuber formation was restricted and these symptoms appeared at a leaf concentration of 0.63 percent. Not Available |
