Direct and residual effects of organics and in combination with inorganic fertilizers applied to acid soils were studied in okra-rice system. Among the treatments vermicompost and poultry manure improved soil pH and exhibited liming effect whereas inorganic fertilizer decreased soil pH. Inorganic fertilizer contributed to 78% of net return in okra but the residual effect was observed in inorganic and vermicompost combination. Soil available nitrogen and potassium had increased at 100% recommended dose, compensated crop uptake at 75% but depletion was observed at 50%. Uptake of nitrogen was higher for okra from inorganic fertilizer but higher phosphorus and potassium uptake from vermicompost was observed for rice. Organics showed better correlation between soil pH and Zn uptake by okra and significant residual effect on rice. But it reduced the solubility of Fe and its uptake by okra and indicated a negative correlation between pH and DTPA extractable Fe2+. Not Available |
