“…Similar results were also reported by Hill (1990) and Mahboubi et al (1993). Some authors have finally suggested that tillage practices can also alter soil physical properties and, consequently, the surface and subsurface hydrology of agricultural fields, especially when a similar tillage system has been practiced for a long period (Buschiazzo et al, 1998;Gómez et al, 1999;Hill, 1990;Özgöz et al, 2007;Tsegaye and Hill, 1998).…”

“…Soil and crop management practices have the potential to provide several benefits to farmers and to the ecosystem, and have been studied by many authors (Blanco-Canqui et al, 2011;Hill, 1990;Osunbitan et al, 2005;Özgöz et al, 2007;Radcliffe et al, 1988;Raper et al, 2000;Sharratt et al, 2006). However, studies on these soil management practices, especially tillage, have yielded conflicting results for soil properties in general and for soil physical properties in particular.…”

A b s t r a c t. Soil and crop management practices can affect the physical properties and have a direct impact on soil sustainability and crop performance. The objective of this study was to investigate how soil physical properties were affected by three years of tillage, cover crop and crop rotation treatments in a corn and soybean field. The study was conducted on a Waldron siltyloam soil at Lincoln University of Missouri. Soil physical properties studied were soil bulk density, volumetric and gravimetric water contents, volumetric air content, total pore space, air-filled and water-filled pore space, gas diffusion coefficient and pore tortuosity factor. Results showed significant interactions (p<0.05) between cover crop and crop rotation for bulk density, gravimetric and total pore space in 2013. In addition, cover crop also significantly interacted (p<0.05) with tillage for bulk density and total pore space. All soil physical properties studied were significantly affected by the depth of sampling (p<0.0001), except for bulk density, the pore tortuosity factor and total pore space in 2012, and gravimetric and volumetric in 2013. Overall, soil physical properties were significantly affected by the treatments, with the effects changing from one year to another. Addition of a cover crop improved soil physical properties better in rotation than in monoculture.

“…Other studies have also shown that when similar tillage system such as conventional plowing, have been practiced for a long period, the practice can alter soil physical properties and subsequently soil hydrological behaviors and agricultural production (Hill, 1990;Buschiazzo et al, 1998;Tsegaye and Hill, 1998;Gomez et al, 1999;Özgöz et al, 2007). Conventional plowing has been practiced for centuries in the Tigray region and it has reported as a factor that aggravates soil and nutrient losses (Habtegebrial et al, 2007;Araya et al, 2011Araya et al, , 2012.…”

“…The increment of production by reduced plowing could be as a result of its effect on soil properties and thereby on an overall hydrological behaviour of the cultivated land soils (Hill, 1990;Aune et al, 2006;Özgöz et al, 2007). Other researchers (e.g., Rachman et al, 2003;Mulumba and Lal, 2008;Jabro et al, 2009) noted that it is essential to select site specific tillage practice that sustains soil properties and favors successful growth of agricultural crops in the short, medium and long-terms.…”

“…But the consequence of such repeated operations causes moist soil to move to the surface which favors loss of water by evaporation, exposing soil to erosion damage [ 5 ]. Many other studies have also noted that when a similar tillage system has been practiced for a long period, the practice can alter soil properties and agricultural production [ 13 – 17 ]. Conventional tillage is reported as a factor that aggravates crop yield reduction [ 3 , 18 , 19 ], but it is still continuing as sole cultivation method in northern Ethiopia.…”

The low average grain yield (0.7 ton ha−1) of tef in Ethiopia is mainly attributed to low soil fertility, and inappropriate tillage and weeds control practices. Despite this, limited scientific information has been documented so far on their interaction effects on tef crop productivity in northern Ethiopia. The objective of this study was to assess the separate and interaction effects of tillage, fertilizer, and weed control practices on tef yield and yield components in the conditions of northern Ethiopia. A two-year study (2008-2009) was conducted using split-split-plot design with three replications. In the main plot, three tillage treatments: conventional tillage (6 times tillage passes) (T1), four times tillage passes (T2), and reduced tillage (single tillage pass at sowing) (T3) were applied. The fertilizer treatments in the subplots were: no fertilizer (F1); 23 kg N ha−1 (F2); 23 kg N ha−1 and 10 kg P ha−1 (F3); 23 kg N ha−1 and 2.5 ton manure ha−1 (F4); and 2.5 ton manure ha−1 (F5). The sub-subplot weed control treatments included farmer weed control practice or hand weeding (W1); 2,4 D at 0.75 kg ha−1 at five-leaf stage; 2,4 D at 0.75 kg ha−1 at six-leaf stage; 2,4 D at 1.5 kg ha−1 at five-leaf stage; and 2,4 D at 1.5 kg ha−1 at six-leaf stage. This study showed that the separate and interaction effects of tillage, fertilizer, and weed control practices significantly affected tef crop yield and yield components in both crop seasons. T2 increased tef yield by >42% over the other tillage and F3 increased yield by >21% over the other fertilizer treatments. Grain yield increased by >23% due to W1. This study thus suggested that promising treatments such as T2, F3, and W1 should be demonstrated at on-farm fields in order to evaluate their performance at farmers' conditions.
