Assessment of productivity, nutrient uptake and economic benefits of rice under different nitrogen management strategies.

ABSTRACT:

Background

Integrating a chemical nitrogen (N) fertilizer with an organic fertilizer and using slow-release mechanism are important N management strategies to increase the N utilization efficiency (NUE) and grain yield of rice. However, the performances of both N management strategies on the productivity, the nutrient absorption and utilization efficiency, and the economic benefits of rice have not yet been comprehensively evaluated.

Methods

A 2-year field experiment was conducted with seven N management strategies without fertilizer (control), 100% conventional N fertilizer (conventional compound fertilizer and urea) (N₁₀₀), 75% conventional N fertilizer with 25% organic-inorganic compound fertilizer (N₇₅+OICF₂₅), 50% conventional N fertiliz
