Determination of Attributes in Cotton (Gossypium hirsutum L.) Genotypes in Corn-Soybean Rotation Associated with Acid Amended Soils in the Colombian Eastern Plains

For the last 15 years, Colombia has developed a research process leading to the expansion of its agricultural frontier at the flat well drained savannas of the Eastern Plains, by improving predominantly acid soils with liming to increase base saturation with depth, vertical liming —as its referred l...

Genotypes in Corn-Soybean Rotation Associated with Acid Amended Soils in the Colombian Eastern Plains Determinación de atributos en genotipos de algodón (Gossypium hirsutum L.) en la rotación maíz-soya asociados a suelos ácidos mejorados de la altillanura colombiana Campuzano Duque, Luis Fernando Caicedo Guerrero, Samuel Guevara Agudelo, Judith For the last 15 years, Colombia has developed a research process leading to the expansion of its agricultural frontier at the flat well drained savannas of the Eastern Plains, by improving predominantly acid soils with liming to increase base saturation with depth, vertical liming —as its referred locally—, crop rotation with rice, corn, soybeans, and with the potential to include other crops like cotton in the rotation system. To achieve this, a pioneering research in Colombia was conducted to determine the adaptation of cotton in the acid conditions of the high plains improved sheets. An Agronomic evaluation test was developed using five elite genotypes of cotton in a design of a randomized complete block at four locations in soils with base saturation above 80 %. The results identified a genotype (LC-156), which presented an adaptation to the high plains, associated with an average yield of 2.2 t/ha of cottonseed, 1.5 t/ha of cotton fiber type medium-long, a percentage of fiber extraction above 36.0 %. The comparative advantage of this region for sustainable cotton production is given by the yield of cotton fiber —which ishigher than the national average—, to the 33.2 % reduction in production costs, the quality of long/medium-fiber destined for export and the absence of the pest insect of greatest economic impact in Colombia: the weevil (Anthonomus grandis Boheman). En Colombia, en los últimos 15 años, se ha desarrollado un proceso de investigación para la ampliación de la frontera agrícola focalizado en la altillanura plana, con énfasis en la construcción de capa arable asociado a la saturación de bases, mediante el encalamiento, la labranza vertical y la rotación arroz, maíz y soya, con la posibilidad de otras especies como el algodón que podrían ingresar al modelo. Para ello, se realizó una investigación pionera en Colombia para determinar la adaptación del algodón en las condiciones de las sabanas ácidas mejoradas de la altillanura. Se desarrolló una prueba de evaluación agronómica con cinco genotipos élites de algodón en un diseño de bloques completos al azar en cuatro localidades en suelos con una saturación de bases superior al 80 %. Los resultados permitieron identificar un genotipo (LC-156), que presentó una adaptación a la altillanura, asociado a un rendimiento promedio de 2,2 t/ha de algodón semilla, 1,5 t/ha de algodón tipo fibra media a larga y un porcentaje de extracción de fibra superior al 36,0 %. La ventaja comparativa de esta región para una producción sostenible de algodón está dado por el rendimiento de algodón fibra superior al promedio nacional, reducción del 33,2 % en los costos de producción, calidad de fibra media larga con destino para la exportación y la ausencia del insecto plaga de mayor importancia económica en Colombia, el picudo (Anthonomus grandis Boheman). 2016-01-21 2019-08-09T19:30:06Z 2019-08-09T19:30:06Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistacta.agrosavia.co/index.php/revista/article/view/371 10.21930/rcta.vol16_num2_art:371 http://hdl.handle.net/20.500.12324/35166 spa http://revistacta.agrosavia.co/index.php/revista/article/view/371/336 application/pdf Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Ciencia y Tecnología Agropecuaria; Vol 16 No 2 (2015); 251-263 Ciencia y Tecnología Agropecuaria; Vol. 16 Núm. 2 (2015); 251-263 revista Corpoica Ciência e Tecnologia Agropecuária; v. 16 n. 2 (2015); 251-263 2500-5308 0122-8706 10.21930/rcta.vol16-num2
