(Universidad de Chile, Facultad de Ciencias Agronómicas, 2003)El extracto expone algunas observaciones al agricultor que recién se inicia en este sistema, y muestra los efectos que éste produce en las propiedades del suelo; posteriormente revisa el tema de rastrojos, incluyendo el ...
-
(Springer, 2019)Crop yields usually respond to crop rotation, but they may interact with tillage system and year (as an integration of variables, mainly in terms of temperature and precipitation). The objective of this study was to evaluate ...
-
(Universidad de Chile, 2012)Las estrategias de manejo del nitrógeno pueden tener un impacto importante en el rendimiento y proteína en grano, como también sobre el medio ambiente, estrategias que pueden ser definidas mediante el uso del SPAD. Este ...
-
(INIA, 2013)The genetic coefficients, representative of a crop, are necessary to use growth models; in many cases the range of the species is known, but there are no specific values for varieties. Durum wheat (Triticum turgidum L. ...
-
(INST INVESTIGACIONES AGROPECUARIAS, 2011)We studied the abundance, species composition, and depth distribution of the weed seed bank under no-tillage (NT) and conventional tillage (CT) at two sites, A and B. Soil samples were taken at three soil depths (0-2, 2-5, ...
-
(ELSEVIER SCIENCE BV, 2013-01)Soil management practices may change the soil properties. The magnitude of the change varies according to the soil property, the climate, and the type and time of implementation of a particular management system. The aim ...

(Universidad de Chile, 2010)En Chile se ha observado problemas de establecimiento y rendimiento de lupino cuando se cultiva después de trigo en condiciones de cero labranza con rastrojos sobre el suelo. Esta inhibición ha sido descrita como efecto ...
-
(Elsevier, 2013-05)La quinua es un pseudocereal andino destacado como un cultivo que tolera la sequía; sin embargo, existen pocos estudios que asocien la intensidad del estrés hídrico con la reducción del rendimiento. El objetivo de este ...

Hydraulic conductivity in a soil cultivated with wheat-rapeseed rotation under two tillage systems (Springer, 2020)To evaluate the effect of tractor transits and tillage system operations on soil pore functioning in a Haploxeroll, soil physical properties were measured on a field located in central Chile. The study site was divided ...

(2015)Este texto promueve el auto aprendizaje y la integración de conocimientos. En este sentido , los estudiantes podrán ir ejercitando, a medida que los contenidos se vayan desarrollando en las clases de las distintas asignaturas ...
-
(2016)Currently phytosterols are added to processed foods, which increase their cost and therefore limits its use. This manuscript aims to identify foods that are a natural source of phytosterols, as well as analyze how the ...
-
(Elsevier, 2016)In the Chilean market there are hybrid varieties of radicchio (Cichorium intybus L) with high yield and homogeneity, where its main limitation is the high cost of the seed. The most important variety is 'Leonardo', which ...
-
(Universidad de Chile, 2011)Dentro de los ecosistemas terrestres, el suelo se considera el mayor reservorio y sumidero de carbono (C) y la respiración de suelo (RS) corresponde a uno de los principales flujos de transferencia de dióxido de carbono ...
-
(ELSEVIER SCIENCE BV, 2008-06)No-tillage systems affect soil properties depending on the soil, climate, and the time since its implementation. In heavy no-tilled soils a surface compacted layer is commonly found. Such layer can affect root growth and ...
-
(Frontiers Media SA, 2017)Yield under water stress (YS) is used as the main criterion in the selection of wheat varieties for dry Mediterranean environments. It has been proposed that selection of genotypes using YS assisted by morphological and ...
