Abstract

Soil acidity has detrimental effects on growth of turmeric. High aluminum (Al) and iron (Fe) concentrations represent a reduction in growth and yield of crops like turmeric in acidic soils. Field experiments were conducted on turmeric (Curcuma longa L.) crop variety T-12 on silty clay loam soil with eleven treatments. The results revealed that FYM application @ 20 t ha–1 both as soil incorporation and mulch significantly reduced exchangeable acidity from 0.27 c mol kg-1 in control to values 0.17 and 0.18 c mol kg-1, respectively. Application of 10 t, 15 t and 20 t FYM/ha significantly decreased exchangeable, extractable, amorphous, crystalline and total Al in comparison to 100 % NPKS. The extent of reduction was highest in 100% NPKS + 20t FYM ha–1 as soil incorporation and decrease in exchangeable, extractable, amorphous, crystalline and total Al was 18, 21, 12, 9 and 0.9% over 100% NPKS alone. Similarly, the highest reduction in all these forms of Fe viz. exchangeable, extractable, amorphous, crystalline and total iron was recorded in 100% NPKS + 20 t FYM/ha as soil incorporation over control and the decrease was 27, 23, 8, 3 and 0.4% respectively.
