Ammonium and nitrate are the major forms of nitrogen (N) present in tropical soils. An experiment was conducted to assess the influence of nitrate and ammonium forms (N03-, NH4+, and mix of N03- + NH4+), and levels (1.5-12.0 mM) of N on the growth and nutrition of cacao (Theobroma cacao L). Growth parameters were significantly influenced by N forms, and nitrogen supplied as NH4+ proved better for the growth of cacao compared with N03- form and mixtures of these two forms. Irrespective of the forms of N, levels of N had no significant effect on plant growth parameters. Nutrient efficiency ratios (NERs)(shoot dry matter produced per unit of nutrient uptake) for macronutrients were sulfur» phosphorus» calcium> magnesium> nitrogen > potassium (S>p> Ca» Mg> N> K) and for micronutrients NERs were in the order of copper» boron» zinc» ironc- manganese (Cu» B> Zn> Fe>Mn). |
