Aporte de nitrógeno proveniente de pollinaza al cultivo de brócoli (Brassica oleracea L.)
The nitrogen (N) contribution from chicken manure to broccoli crop (Brassica oleracea L.) was evaluate using the 15N isotopic technique. Six treatments combining chemical fertilizer (N-phosphonitrate) and organic fertilizer (N-chicken manure) at a total rate of 300 kg N ha-1 were established: 1) 0 +...

Torres Nava, Daniel Sandoval Castro, Engelberto Peña-Cabriales, Juan José Vera-Núñez, José Antonio Absorción de 15N fertilizante orgánico sinergismo 15N-uptake organic fertilizer synergetic The nitrogen (N) contribution from chicken manure to broccoli crop (Brassica oleracea L.) was evaluate using the 15N isotopic technique. Six treatments combining chemical fertilizer (N-phosphonitrate) and organic fertilizer (N-chicken manure) at a total rate of 300 kg N ha-1 were established: 1) 0 + 300; 2) 100 + 200; 3) 150 + 150; 4) 200 + 100; 5) 300 kg N-phosphonitrate ha−1 + 0 kg N-chicken manure ha-1; and 6) an unfertilized N control. Five replicates per treatment were established under a statistical design of random blocks. The highest yield of broccoli (heads) corresponded to treatments 200 kg N-phosphonitrate ha-1 + 100 kg N-chicken manure ha-1 and 300 kg N-phosphonitrate ha-1 yielding 16 and 17 Mg ha-1, respectively. The highest value of total N-uptake (347 kg N ha-1) was observed in treatment corresponding to 150 kg N-phosphonitrate ha−1 + 150 kg N-chicken manure ha−1. The 15N data indicate low values of N-fertilizer uptake (3.2-4.1%) when manure was applied. The N-phosphonitrate alone treatment showed a higher value of N-fertilizer (28.7-48.0%) than treatment 200 kg N-phosphonitrate ha−1 + 100 kg N-chicken manure ha−1 (4.5-5.1%). The N uptake by plants from manure was 29.5% average. The combination of chemical and organic fertilizers resulted in a higher total N-uptake. The constant application of manure to soil under broccoli production in Puebla region resulted in a significant contribution of soil N to the broccoli crop. Se evaluó a través de la técnica isotópica de 15N el aporte de nitrógeno (N) proveniente de la pollinaza durante el desarrollo del cultivo de brócoli (Brassica oleracea L.). Se establecieron seis tratamientos a una dosis de 300 kg N ha-1producto de la combinación de fertilizante químico (N-fosfonitrato) y fertilizante orgánico (N-pollinaza): 1) 0 + 300; 2) 100 + 200; 3) 150 + 150; 4) 200 + 100; 5) 300 kg N-fosfonitrato ha−1 + 0 kg N-pollinaza ha−1; y 6) testigo sin fertilización N, en un diseño de bloques al azar con cinco repeticiones. Los resultados mostraron el mayor rendimiento en los tratamientos 200 kg N-fosfonitrato ha-1 + 100 kg N-pollinaza ha-1 y 300 kg N-fosfonitrato ÂÂÂÂÂ ha-1 (16 y 17 Mg ha-1, respectivamente). El mayor rendimiento de N total (347 kg N ha-1) ocurrió a 150 kg N-pollinaza. Los datos de 15N indican una baja asimilación de N-fertilizante, destacando los tratamientos donde se aplicó pollinaza con los valores menores (3,2-4,1%) en comparación con el tratamiento a base de N-fosfonitrato (28,7-48,0%). La absorción de N-pollinaza fue aproximadamente 29,5%. Los datos sugieren un efecto sinérgico entre el fertilizante químico y orgánico, ya que se observó una alta contribución del N del suelo dadas las constantes aplicaciones de pollinaza al sistema de producción en Tepeaca, Puebla.

contribution of nitrogen from chicken manure to broccoli crop (brassica oleracea l.) |
| description |
The nitrogen (N) contribution from chicken manure to broccoli crop (Brassica oleracea L.) was evaluate using the 15N isotopic technique. Six treatments combining chemical fertilizer (N-phosphonitrate) and organic fertilizer (N-chicken manure) at a total rate of 300 kg N ha-1 were established: 1) 0 + 300; 2) 100 + 200; 3) 150 + 150; 4) 200 + 100; 5) 300 kg N-phosphonitrate ha−1 + 0 kg N-chicken manure ha-1; and 6) an unfertilized N control. Five replicates per treatment were established under a statistical design of random blocks. The highest yield of broccoli (heads) corresponded to treatments 200 kg N-phosphonitrate ha-1 + 100 kg N-chicken manure ha-1 and 300 kg N-phosphonitrate ha-1 yielding 16 and 17 Mg ha-1, respectively. The highest value of total N-uptake (347 kg N ha-1) was observed in treatment corresponding to 150 kg N-phosphonitrate ha−1 + 150 kg N-chicken manure ha−1. The 15N data indicate low values of N-fertilizer uptake (3.2-4.1%) when manure was applied. The N-phosphonitrate alone treatment showed a higher value of N-fertilizer (28.7-48.0%) than treatment 200 kg N-phosphonitrate ha−1 + 100 kg N-chicken manure ha−1 (4.5-5.1%). The N uptake by plants from manure was 29.5% average. The combination of chemical and organic fertilizers resulted in a higher total N-uptake. The constant application of manure to soil under broccoli production in Puebla region resulted in a significant contribution of soil N to the broccoli crop. |
