“…Pod number, seed number and grain yield per plant were higher for RT than CT. Some researchers reported that RT gave higher kernel per spike than CT (Hemmat and Eskandari 2004a, b;Ozpinar, 2006). There was no statistically significant difference in grain yield between the two tillage methods for chickpea in this season.…”

To cite this paper: Kayan, N., İ. Kutlu, N.G. Ayter and M.S. Adak, 2017. Effects of different tillage systems and soil residual nitrogen on chickpea yield and yield components in rotation with wheat under dry farming areas. AbstractThe aims of this study were to determine how the tillage system and residual N of soil affected chickpea yield and its trait in rotation with wheat under Central Anatolia Region. In this study, two tillage methods viz. conventional and reduced tillage, three crop rotations; wheat-wheat; wheat-fallow; wheat-chickpea and four N levels of 0, 50, 100, 150 kg ha -1 were evaluated for four years duration (2012)(2013)(2014)(2015). Tillage methods were maintained into main plots, crop rotation into subplots and N levels into sub-sub plots. Only chickpea in continuous rotation with wheat was examined in this study. The results were evaluated according to split plot design with three replicates. Grain yield was higher under conventional tillage (CT) than reduced tillage (RT) in both of the growing seasons. Some important yield components were higher under RT than CT especially in the second growing season. These differences of tillage methods may also be due to climatic conditions. Residual fertilizer N significantly affected chickpea grain yield which increased with 100 and 150 kg N ha -1 levels. Results also indicated that; conventional tillage may be more appropriate for chickpea in rotation with wheat. Chickpea grain yield was also affected when N fertilizer applied to wheat.

“…Esto se hace con el fin de determinar propiedades sensibles a cambios negativos y así poder tomar medidas de manejo para mantener las condiciones del suelo necesarias para que las raíces de las plantas no encuentren limitaciones para absorber y transportar nutrientes y agua a la parte aérea (Amézquita y Londoño 1997;Albanesi et al 2003;Ozpinar 2006;Rondón et al 2006;Su et al 2007;Álvarez y Steinbach 2009;Jin et al 2009;VieiraCavalieri et al 2009). …”

<p>Con el fin de determinar los cambios de algunos indicadores de calidad física en suelos en la zona cerealera fría de Nariño, Colombia, se evaluó el efecto del tiempo de uso en diferentes sistemas y pendientes. Los resultados mostraron que el aumento del tiempo de uso generó cambios negativos en algunos indicadores hídricos y volumétricos. El agua disponible disminuyó de manera proporcional a la profundidad, en un 12 % y un 33 % para suelos cultivados durante 45 y 70 años, respectivamente. El cambio a uso agrícola de rotación trigo-maíz (rt-m) durante 25 y 70 años aumentó el nivel de escorrentía en un 95 % y un 97 % respectivamente en cuanto al testigo, lo que significa que algunas propiedades hídricas del suelo se afectan antes de los 25 años de uso intensivo. Frente al testigo, la densidad aparente del suelo con pastura se incrementó un 27,6 % y la del suelo con uso agrícola se incrementó un 10 %. Para el suelo con uso agrícola (rt-m) no hubo diferencias en densidad aparente ni densidad real, lo que sugiere que, en pocos años de uso, el suelo pierde volumen. Con excepción de la pastura, la porosidad total alcanzó valores agronómicos aceptables, con porcentajes de microporos mayores al 50 % de la porosidad total, lo que puede generar problemas de drenaje, suministro de agua y transporte de nutrientes hacia las plantas.</p>

“…Higher yield is usually attributed to increased water conservation, especially in arid and semiarid regions; whereas lower yield is attributed to greater disease and weed infestations and N immobilization (Lopez-Bellido et al 1996;McMaster et al 2002;Ozpinar 2006). Crop yields immediately after no-till conversion period are often appreciably lower than after ploughing but improve after about three years of no-till as soil structural conditions improve (Six et al 2004;Anken et al 2006).…”

A 2-year conservation agriculture experiment was conducted in Southern Italy on durum wheat continuous cropping. Aim of the research was to assess the durum wheat productivity and grain quality in reduced soil tillage systems, according to conservation agriculture principles. The interactions among experimental treatments and climate revealed a close relationship among grain yield, grain quality and wheat growth conditions. Specifically, conventional tillage (CT, plowing and 2 disc harrowing) showed in the 2-year period higher grain production than reduced tillage treatments, minimum (MT, 1 disc harrowing) and No tillage (NT), especially for good crop water availability (3.29 t ha -1 of grain yield in CT, 2.67 in MT and 2.54 in NT). The amount of rainfall (above the average in both years) and its distribution in the growing seasons (more regular in the first year) strongly influenced wheat-grain quality indices (11.97% of protein content in the first year and 9.82% in the second one). Also, the wheat quality resulted more sensitive to the "Year × Tillage" interaction, with differences among tillages more evident in the second year and favourable to NT and MT. Spectral vegetation indexes (NDVI and TVI) measurements at flowering, have been shown to be useful to support farmers in N-late application for improving grain wheat quality. From this experiment carried out during the conversion period and in wet years, wheat managed with CT resulted in higher grain yield and quality, while only test weight showed a significant "Year × Tillage" interaction. Further indications emerged on the need to supply additional (10-20%) seed amount at sowing and crop nitrogen fertilizer in the first transition years in reduced tillage systems compared to conventional ones.
