Abstract

Introduction: rice is the main staple food for more than half of the global population. According to reports, Iran has achieved 20th place in the global ranking for rice production (FAO, 2011). rice plant require large amounts of mineral nutrients including Nitrogen for their growth, development and grain production (Ma, 2004). Managing rice crop’ s Nitrogen nutrition is difficult because lowland rice crop culture leads to Nitrogen losses through ammonia volatilization, nitrification, denitrification, leaching, and runoff, which decreases the availability of Nitrogen for rice plants. The density that results a maximum yield depends on temperature, solar radiation, moisture, soil fertility and other factors. Use of optimum planting density per unit area ensures plants to grow properly both in the upper ground and underground parts of the plant through better utilization of solar radiation and nutrients (Bozorgi et al., 2011)...
