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
