Con el objetivo de determinar la influencia de los niveles crecientes de nitrógeno y potasio een el crecimiento y producción de bulbos de cebolla, fue llevado a cabo un experimento en el Campo Experimental del Instituto de Investigación y Transferencia Agropecuaria, ubicado en el sector Pampas de San Juan, Laredo. Se utilizó para ello semilla certificada de cebolla var. “Roja Arequipeña”. La investigación se instaló en un diseño de Bloques Completos al Azar con arreglo factorial 3x4 con tres repeticiones y doce tratamientos que resultaron de las combinaciones 60, 120, 180 y 240, kg de N ha-1; y 40, 80 y 160 kg de K2O ha-1. Se utilizó, además, como dosis única 80 kg de P2O5.ha-1y como fuentes, nitrato de calcio y sulfato de potasio. Al momento del transplante, se aplicó todo el fosforo junto con 1/3 de N y 1/3 de K. Treinta días después, durante el aporque, se aplicaron ...

Whit the objective to determining the influence of increasing levels of nitrogen and potassium in the growth of onion, was carried an experiment in Pampas de San Juan, Laredo during October 2010 to January 2011. We used certified seed red onion var. "Red Arequipeña". The treatments were the combinations results of 60, 120, 180 and 240 kg N ha-1 and 40, 80 and 160 kg K2O ha-1, used as a single dose, 80 kg P2O5 ha-1. The experiment was designed in randomized complete block with 3x4 factorial arrangements with three replications. The results of this research to conclude that the dose of 120 kg N.ha-1, was obtained a linear response to nitrogen ascendant of 44.9cm in height with 90 days of DDT and 14.2 mm for diameter of the false stem with 60 N.kg-1 to 104 days DDT. There were no responses to potassium in this variable. There were no responses to NxK for the number of leaves. 

With the objective to determine the influence of increasing levels of nitrogen and potassium in the growth and yield of onion bulbs, one experiment was carried in the Experimental Institute for Agricultural Research and Technology located in the area Pampas de San Juan Laredo, The freedom. The installation of the nursery was made on 03.10.2010 and 11.11.2010 the transplant, the assessments were made until 31.01.2011, the day of harvest. The experimental design was randomized complete block with 3x4 factorial arrangement with three replicates and twelve treatments resulting from combinations 60, 120, 180 and 240 kg N ha-1, and 40, 80 and 160 kg K2O has -1, using 80 kg as a single dose of P2O5.ha-1. We used certified seed onion var. "Red Arequipeña." We assessed plant height, number of leaves, diameter of the false stem, polar and equatorial diameter of the bulb, and performance. The resu...
