- Effect of magnesium silicate in cv. ‘ICA Cerinza' common bean ( Phaseolus vulgaris L.) under field conditions Elberth Hernando Pinzón-Sandoval Wilmer Alejandro Quintana-Blanco German Eduardo Cely-Reyes Agrociencias Silicon Amendment Beneficial element Leguminous vegetable Nutritional dynamics The bean crop is very important in Colombia, being a generator of income and employment; and furthermore very important within the diet of the population due to its high protein content. Currently, bean production is not sufficient to meet the demand in the country, because of phytosanitary problems, scarce replacement of varieties and inappropriate handling of mineral nutrition of cultivars. Nowadays, the use of products for soils rich in silicon represents an alternative for production increase, because they contribute markedly in nutritional dynamics. So, the purpose of this research was to assess the effect of magnesium silicate on the physiological behavior of ‘ICA Cerinza' bean cultivar under agro-ecological conditions in Tunja (Boyacá, Colombia). For that, a completely random design with four treatments each was used, corresponding to increasing doses of magnesium silicate (0, 300, 600 y 900 kg ha-1) with four replications. The total chlorophyll content, leaf area, leaf thickness, fresh and dry mass, yield components, silicon and phosphorus leaf content were evaluated. Statistical differences between treatments (P≤0.05) were found in all variables tested. The application of increasing doses of magnesium silicate showed a positive effect, being the treatment of 900 kg ha-1 which presented the best results. This indicates that the contribution of silicon as a beneficial element that can submit a favorable response to physiological level in crops which do not use bio-accumulators. However, this response can be linked to agro-ecological conditions, the type of product and also the dose used. 2017 artículo científico 0304-2847 https://www.redalyc.org/articulo.oa?id=179955074006 https://www.redalyc.org/journal/1799/179955074006/ https://www.redalyc.org/journal/1799/179955074006/html/ https://www.redalyc.org/journal/1799/179955074006/179955074006.epub https://www.redalyc.org/journal/1799/179955074006/movil 10.15446/rfna.v70n3.62679 en http://www.redalyc.org/revista.oa?id=1799 Revista Facultad Nacional de Agronomía - Medellín application/pdf Universidad Nacional de Colombia Revista Facultad Nacional de Agronomía - Medellín (Colombia) Num.3 Vol.70
