Effects of Integrated Nutrient Management on Rice (Oryza sativa L) Yield and Yield Attributes, Nutrient Uptake and Some Physico-Chemical Properties of Soil: A Review

Abebe Worku Wolie, Merkuz Abera Admassu


Rice (Oryza sativa L.) is one of the most important stable food crops in the world.  Exploiting the production potential of high yielding rice varieties through agronomic management is one of the alternatives to feed the ever growing population. For this, fertilizers from different sources have contributed substantially to the spectacular increase in rice yield and to improve soil properties. The objective of this paper is to comprehensively review the literatures and recommend the best proportion different source of fertilizers for sustainable rice production and soil properties improvement. Different original research articles published elsewhere in the world were reviewed to compile the information. Rice yield and yield contributing traits significantly increased with the use of compost, vermin compost sasbania, green manure and FYM in combination with chemical fertilizer than individual sources in most of the findings. Higher total nutrient uptake by rice crop was also recorded under integrated nutrient source. Moreover integrated application of inorganic and organic fertilizers helped in increasing the availability of nutrients and improves major physical and chemical characteristics of the soil. In conclusion, application of 50 % fertilizers from organic sources and 50 % from inorganic sources is the best combination and reported by many scientists for rice yield and soil properties improvement.
