Crop Establishment Methods and Integrated Nutrient Management Improve: Part II. Nutrient Uptake and Use Efficiency and Soil Health in Rice (Oryza sativa L.) Field in the Lower Indo-Gangetic Plain, India

Rice, the predominant food crop in India, is being grown traditionally with improper plant nutrient management mostly under flooded situation. Recent advancement research on science focuses water-saving rice technologies for maximization and water productivity backdrop of a shrinking resource base ensuring environmental agricultural sustainability. Under this situation, an experiment was conducted two consecutive years split-plot design keeping cultivation methodologies, viz., aerobic culture, System Rice Intensification (SRI), conventional culture main plots integrated (INM) treatments sub-plots. The aimed at understanding effects different production systems INM content, uptake, use efficiency. change soil quality parameters also studied to understand impact establishment methods (CEM) options. Significant reduction (p ? 0.05) uptake efficiency observed compared SRI method, although showed highest physiological nitrogen Post-harvest available Fe status significantly lower (mean 10.39 ppm) other technologies; however, Zn higher over Although potassium not affected due methods, phosphorus were influenced remarkably. Soil microbial improved comparison rice. proved be most efficient method enhancement efficiency, enrichment chemical microbiological quality. Irrespective nutrition parameters. study revealed that, alluvial soils Indo-Gangetic Plains Eastern can considered as method. improve if proper adopted.
