MEJIA DE TAFUR, María Sara; ESTRADA, Edgar Iván  y  FIGUEROA, Olfer Andrés. Physiological response of coriander to different levels of potassium and nitrogen. Acta Agron. [online]. 2008, vol.57, n.3, pp.195-198. ISSN 0120-2812.

To evaluate the response of coriander cv. Unapal-Precoso at different levels of N and K an experiment was carried out. Plants were sown in pots with 4 kg of river washed sand and irrigated with nutrient solutions (Control: solution of Hougland and Arnon, other treatments: different concentrations of N and K). A complete randomized design with seven treatments and five repetitions was used. Four sampling every nine days until the final harvest were taken. With the high concentration of K greater biomass accumulation and the lowest post-harvest loss of water was observed. The optimum range of N concentration in the nutrient solution was estimated between 3.9-8.7 mM and the critical level of K deficiency was 8.4 mM.

Palabras clave : Coriandrum sativum; nutritive solution; requirements of N and K..
