Teosinte was sown at 30, 45 and 60 kg seed/ha in rows 30 cm apart in the summer monsoon season of 1971 and 1972 and was given 0, 30, 60 or 90 kg N/ha and 0 or 20 kg P2O5/ha. Fodder yields showed linear response to N rates up to 90 kg/ha; application of 20 kg P2O5/ha significantly increased fresh weight and DM yields and the optimum sowing rate was 45 kg/ha. Metabolizable energy (ME), CP, crude fat and CF contents were increased and the nutritive ratio was decreased (due to the increase in proteins and reduction in carbohydrate) by increased levels of N, P and by the optimum sowing rate. The interaction of N and P significantly increased ME; at 20 kg P2O5 + 90 kg N/ha, ME was 3342 Mcal/ha greater than with any other treatment.
