A greenhouse experiment was conducted to examlne the effect of organic matter application on nitrogen content ofcorn leaf tissue grown in coastai sandy soil. The experiments were arranged in a complete randomized design using doses of organic matter (5, 10 and 15 tons ha i) treated to corn crops in three differenl doses of N-urea (i15; 135 and 155 N kg ha 1). The experimental results show that Doses of 10 and '15 tons of ha I oforganic matter have an effect on nutrient nitrogen status in coastal sandy soil, organic maiter (X) has a contribution of 99 percent to nitrogen content of corn leaf tissue (y). with the equation Y = 5,610 * 1,107 X - 0,A462X'?
