“…The LF accounts for the majority of SOM initially lost after cultivation (Cambardella and Elliott, 1993), and with the transition from ST to CT, the proportion of total C that is found in the LF increases (Schwenke et al, 2002). The increased proportion of LF in SOM and reduced soil disturbance may be the reasons that aggregate stability often increases with CT regardless of whether or not there are overall increases in total SOM (Cannell and Hawes, 1994;Hao et al, 2000;Chan et al, 2001;Hernanz et al, 2002).…”

T he soil C sequestration potential of reduced tillage or CT has been extensively studied in other parts of the country, but there has been very little CT research under arid, irrigated agriculture systems, like those in California. California cropping systems are intensively managed and require tillage operations to address furrow irrigation needs. Diverse crop rotations and crops untested for reduced tillage regimes have complicated the development of CT approaches in this highly productive agricultural region. Reducing tillage of agricultural soils may improve agricultural sustainability by reducing fossil fuel consumption, labor needs, equipment maintenance, and soil erosion, and increase soil water conservation and soil C sequestration (Unger et al., 1997; Lal, 2001). Soil C sequestration potential is dependent on a number of factors including climate and parent material. California agricultural soils often have high clay content (loam to loamy clay) because of the depositional environment of the San Joaquin Valley. As a result, these soils may have a greater potential to promote organo-mineral interactions and stabilize C through aggregation; however, irrigation combined with California's warm climate (near-surface soil temperatures often averaging between 25 and 35°C) may enhance decomposer activity and limit the potential for soil C sequestration.

“…Since the worldwide adoption of conservation agriculture, several studies have reported its effect on crop yield, soil physical properties, soil moisture and organic matter (Alvarez and Steinbach, 2009). The effects on grain yield have ranged from an increase, a decrease or no change (Hao et al, 2001). This effect depends on weather conditions and crop sequence used, rainfall during crop establishment and on the interaction between many others parameters (Brennan et al, 2014;Ercoli et al, 2017).…”

Conservation agriculture has been proposed as an alternative to conventional agriculture to mitigate the climate change impact and ensure food security. This study examined the effect of three tillage systems, ((conventional tillage (CT), chisel tillage (ChT) and no tillage (NT)) and two crop-rotation systems ((two year crop rotation (2-yr) and three year crop rotation (3-yr)) on some yield and quality parameters of two winter durum wheat genotypes. The results showed that biological yield (BY) and thousand kernel weight (TKW) were neither significantly affected by tillage, crop rotation nor genotype. Only the genotype significantly affected grain yield (GY). Grain protein content (GPC %) showed higher values than straw protein content (SPC %) and NT negatively affected GPC%. Some significant differences of mineral elements were observed according to tillage system applied and NT showed the lowest values of grain N, straw K, straw Ca and straw Na. Tillage system, croprotation system and genotype had no effect on total phenolic content (TPC) and total flavonoid content (TFC). Highly significant negative correlation (-0,378**) was recorded between GY and grain N, and accordingly GPC%. The two winter durum wheat genotypes demonstrated that with the two crop-rotation systems, yields and most of quality parameters under NT and ChT were similar to those under CT. This study expands our knowledge on durum wheat chemistry variation in relation to agricultural system adopted and provides a basis for selecting the adequate crop

“…Conventional tillage involves more field operations and result in more water loss and soil disturbance than conservation tillage. In contrast, conservation tillage improves the soil's physical properties and water storage (Ozpınar and Çay, 2005), increases infiltration rates (Hao et al, 2000) and reduces erosion (Avcı, 2011). Micucci and Taboada (2006) reported that conservation tillage increased organic matter content in the soil.…”

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.
