Respuesta fisiológica del cilantro a diferentes niveles de potasio y nitrógeno

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.
