A complete randomized block design with five treatments and four replicates was used; doses of 236, 75 and 192 kg ha<sup>-1</sup> were used for N, P and K, respectively, mixed with 0, 70, 140 and 210 kg ha<sup>-1</sup> of zeolite. The emission of N<sub>2</sub>O was estimated with a closed static chamber at 15, 25, 36, 45, 56, 65 and 76 days after sowing the crop. The efficient nutrient use was determined with the agronomic and recovery fertilizer efficiency of N-P-K. N<sub>2</sub>O flow and nutrient use efficiencies by treatment showed highly significant differences (<em>P</em>≤0.01); the highest N<sub>2</sub>O flux was found in the control and the lowest was in T4 (210 kg ha<sup>-1</sup> zeolite, 236 kg ha<sup>-1</sup> nitrogen, 75 kg ha<sup>-1 </sup>phosphorus P<sub>2</sub>O<sub>5</sub> and 192 kg ha<sup>-1</sup> potassium K<sub>2</sub>O) as contrasted with the greater nutrient use efficiency in T4, except for nitrogen. This showed the contribution of zeolite in the reduction of N<sub>2</sub>O emissions and in yield increases.}, number={2}, journal={Revista Colombiana de Ciencias Hortícolas}, author={Martínez-Herrera, Claudia and Puentes-Páramo, Yina Jazbleidi and Menjivar-Flores, Juan Carlos}, year={2018}, month={Jan.}, pages={416–424} }
