Nathalie) Jaime Lozano-Fernández Luz Fanny Orozco-Orozco Luis Felipe Montoya-Munera Agrociencias yield Capsicum annuum Agronomic management open field condition crop relative growth rate Some unappropriated techniques are found in bell pepper agricultural management. Those are: non-balancing nutritional profile among soil contribution, crop requirements and fertilizer efficiency, excessive use of composite sources and the lack of availability of studies on recommendations in different environments where this crop is grown. In order to mitigate the inadequate techniques in the agronomic management of bell pepper, an evaluation of four fertilization treatments under open field and protected conditions with plastic cover was conducted. Nathalie cultivar was grown during 2014-B and 2015-A at "Corporación Colombiana de Investigación Agropecuaria", -CORPOICA research center, located in Llanogrande, township of Rionegro (Antioquia, Colombia). The treatments (T) evaluated were: T1: 250, 75, 180 and 90; T2: 170, 50, 120 and 60; T3, 100, 40, 80 and 40 and T4: 60, 25, 50 and 25 kg.ha-1 of N, P2O5, K2O and MgO, respectively. T2 and T4 correspond to crop requirements established by previous research. In addition, simple sources were used as follows: Urea, DAP, Potassium chloride and Magnesium sulphate, which were arranged in a split-plot design. For the relative crop growth rate (TCR) and yield variables, differences were shown under two evaluated conditions. In open field condition, the highest production and stem diameter were recorded; there were not differences among treatments. T3 is recommended because it showed similar yield to the other three ones. This Treatment allowed reestablishing and maintaining soil fertility levels, with a rational, efficient and low use of fertilizers, without generating contamination and salinity problems. 2018 artículo científico 0120-2812 https://www.redalyc.org/articulo.oa?id=169959093014 https://www.redalyc.org/journal/1699/169959093014/ https://www.redalyc.org/journal/1699/169959093014/html/ https://www.redalyc.org/journal/1699/169959093014/169959093014.epub https://www.redalyc.org/journal/1699/169959093014/movil 10.1S446/acag.v67n1.64739 en http://www.redalyc.org/revista.oa?id=1699 Acta Agronómica application/pdf Universidad Nacional de Colombia Acta Agronómica (Colombia) Num.1 Vol.67 |
