Abstract:

Rice husk ash can be a substitute for inorganic fertilizers or can be used in combination along with inorganic fertilizers, as an amendment to acidic soils, as a carrier for biofertilizers, etc. It can increase the pH in acid soils and there by nutrient availability and can affect the hydro-physical properties. The magnitude of these effects depends on the characteristics of the rice husk ash (RHA) and the soil, the RHA dosage, and the interaction between soil and RHA (Gonçalves and Bergmann, 2007). Rice husk with pH and EC of 8.94 and 1.08 dS m-1 was taken for an experiment with maize under pot culture conditions. The maximum leaf area (45.5cm2) of maize was observed in the treatment with 100% NP+ 25% K + 15 t ha-1 RHA whereas the maximum SPAD chlorophyll value (45.5) was observed in the treatment with 100% NP+75% K +5 t ha-1 RHA. The higher plant height (76.6 cm) was observed in the treatment with 100% NP+50% K +10 t ha-1 RHA and the highest shoot root ratio (5.54) was observed in the treatment with 100% NPK. Substitution of rice husk ash @ 10 t ha-1 along with 50 % of recommended K can enhance maize growth and growth parameters.
