Among the major nutrients, the requirement of K for cassava is high to the tune of 140-160 kg ha-1. In search of a cheaper source to substitute this costly nutrient, an investigation was carried out in the red loam soils (Rhodic Haplustox) of Kerala to study the effect of different levels of substitution of sodium chloride (NaCl) for muriate of potash on various aspects viz., yield and yield components. growth characters, soil chemical properties, quality of tubers, dry matter production, nutrient uptake and finally on the economics of its use. This paper deals mainly the effect of partial, full and no substitution of Na for K on dry matter production, total plant uptake of nutrients, quality of cassava tubers viz., starch and cyanogenic glucosides and soil chemical properties. Both partial (50% substitution of Na for K) and full substitution (100% with Na substitution) produced the same effect on leaf, stem, tuber and total plant dry matter yield and hence on total plant nutrient uptake. But 100% K (no substitution with Na) produced significantly higher dry matter yield and nutrient uptake. The nutritional status of the soil showed a marked variation inpH, P and K whereas organic carbon, available N, secondary and micronutrient statuswas not modified much due to different levels of substitution.No favourable improvement in quality traits viz.,reduction in cyanogenic glucosides or enhancement in starch content was seen due to partial as well as full substitution. However, 100% K could lower the cyanogenic glucosides and improve the starch percentage of cassava tubers. Not Available |
