Soil- and plant-based fertilizer recommendations hold promise for increasing farmers’ incomes with high-input crops such as cassava. Considering the significance of cassava for the food, nutritional, and economic security of a half billion people globally and the positive response of the crop to fertilizer and manure applications in terms of tuber yield and quality through starch improvement and cyanogenic glucoside reduction, these recommendations were validated and popularized in two districts of Kerala State. Soil and plant samples from nine major cassava-growing districts of Kerala were analyzed for soil reaction, organic carbon, and essential nutrients, which formed the basis for the recommendation. The soil-test-based recommendation [nitrogen (N)–phosphorus (P)–potassium (K)–zinc (Zn) at 82:6.3:68:2 kg ha−1 along with farmyard manure (FYM) at 6.25 t ha−1] resulted in the greatest benefit–cost ratio of 1.75 with improvements in tuber and soil quality Not Available |
