“…Cuando el valor del IET es igual a la unidad existe indiferencia en la asociación de los cultivos involucrados, mientras que si es mayor a la unidad indica efecto de sinergismo positivo en la asociación, habiendo ventajas en la misma y cuando es menor a la unidad ocurre antagonismo o competencia entre la asociación, por lo que la misma presenta desventajas frente al monocultivo (Teixeira et al 2005).…”

Tártago asociado a cultivos anuales: una opción para la agricultura familiar

RESUMENEl tártago por sus características agroecológicas se adapta a la agricultura familiar. Para evaluar la factibilidad de la asociación de tártago con cultivos anuales se instaló un experimento con diseño en bloques completos al azar, con siete tratamientos y tres repeticiones, en el Distrito de Escobar, Departamento de Paraguarí, entre agosto de 2007 y julio de 2009. Los tratamientos fueron T1: monocultivo de maíz; T2: monocultivo de poroto; T3: monocultivo de algodón; T4: monocultivo de tártago; T5: tártago asociado a maíz; T6: tártago asociado a poroto; T7: tártago asociado a algodón. Fueron analizadas altura del cacho primario, altura de plantas de tártago en el primer año y rendimiento en granos de tártago, maíz, poroto y algodón en rama, en monocultivo y asociados y la eficiencia de las asociaciones mediante el Índice Equivalente de la Tierra (IET) en los dos años. La mayor altura de inserción del cacho primario y altura final de plantas se obtuvieron en la asociación del tártago con maíz (149,0 cm), y de tártago con algodón (215,0 cm), respectivamente, evaluadas en el primer año de experimentación. El rendimiento de tártago en el mismo año en monocultivo y en asociación presentó escasa variación, entre 963 y 1059 kg ha -1 . En el segundo año, se obtuvo menor producción en la asociación de tártago con maíz (898 kg ha -1 ) y con algodón (890 kg ha -1 ) que en monocultivo (1056 kg ha -1 ). El IET obtenido en los dos años indica que asociando el cultivo de tártago con algodón, maíz o poroto se logra un uso más eficiente del suelo. Palabras clave: Ricinus communis L., asociación de cultivos, índice equivalente de la tierra, maíz, poroto, algodón. ABSTRACTCastor bean Ricinus communis L., due to its agroecological features, is suitable for family farming. A randomized complete block test was carried out at the district of Escobar, department of Paraguari, Paraguay, between August 2007 and July 2009, in order to assess the feasibility of intercropping castor bean with annual crops, with seven treatments and three repetitions. The treatments were T1: maize monoculture; T2: bean monoculture; T3: cotton monoculture; T4: castor bean monoculture; T5: Castor bean intercropped with maize; T6: Castor bean intercropped with bean; T7: castor bean intercropped with cotton. The following were measured: Primary bunch height, castor bean plant height in the first year and castor bean, maize, beans and cotton yield, both in monoculture and in association with other crops, as well as the association efficiency measured with the Land Equivalent Ratio (LER) in the two years. The highest peaks of primary branch height and the final height of plants were obtained in castor bean in association with maize (149 cm) and castor bean in association with cotton (215 cm) respectively, assessed in the first year of the study. Castor bean yield in monoculture and intercropped during the same year showed slight variation, ranging between 963 and 1059 kg ha -1. In the second year, lower production was obtained in castor bean intercropped wi...

“…However, the effective advantage of this technique compared to monoculture becomes more evident when the crops involved have different requirements in terms of available resources, whether in quality, quantity, or time of need (Teixeira et al, 2005). Thus, intercropping efficiency is dependent on the complementarity between the crops involved, the available management practices, and the environmental conditions (Lithourgidis et al, 2011).…”

This study was to evaluate the nutrition and the agronomic part of bean intercropped with castor crops submitted to sources and levels of B in the Anápolis-GO, Brazil. The treatments consisted of two sources of B (borax = 11% B and boric acid = 17% B) combined with five levels of B (0.0, 0.5, 1.0, 2.0 and 4.0 kg ha -1 in soil) in bean intercropped with castor, plus monoculture, using 1.0 kg ha -1 B. That leaf levels of B and S in beans, and of B, N, Ca, Mg and Fe in castor were influenced by the sources and levels of B in the intercropping. The bean yield intercropped with castor was not influenced by borated fertilization, neither by the interaction of factors. The highest yield of castor intercropped with beans, 2.040 kg of grains ha -1 , was obtained with the 1.9 kg ha -1 of B, regardless of the source used.

“…However, operational cultivation such as manpower, time of cultivation, irrigation and others are minimized and optimized by the intercropping [2]. Another important advantage is the biological control that occurs when the consortiation diversifies the species grown in the same area [3].…”
