to study the effects of scale and tillage management on variability of soil properties in adjacent lands of different tillage type, soil sampling was performed linearly along contour line from the middle position of slope with 5 m intervals. in overall, 45 soil samples were collected from a field with conventional up-down tillage and 40 samples from an adjacent filed with contour tillage. soil ...

The effect of different tillage systems on the size distribution of aggregates and organic carbon distribution and storage in different size aggregates in a Hydragric Anthrosol were studied in a long-term experiment in Chongqing, China. The experiment included three tillage treatments: conventional tillage with rotation of rice and winter fallow (CT-r) system, no-till and ridge culture with rot...

ABSTRACT- Field experiments were conducted to determine the relationship between plant leaf area as the dependent variable with leaves number, leaf dry weight, and total vegetative components dry weight and plant height as the independent variables. Treatments were two tillage systems (conventional and no-tillage) as main plots, and seven sowing dates (11 May, 18 May, 25 May, 1...

The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

Adoption of sustainable tillage can protect soils from biological degradation and maintain soil quality, as compared with conventional management. This paper presents findings from a long-term tillage experiment carried out in Endocalcari-Endohypogleyic Cambisols on a sandy loam soil in Lithuania. The tillage systems were: conventional (CT), moderate (MT), and no tillage (NT). Tillage intensity...

in order to evaluate the effects of convention and conservation (no-tillage and reduced tillage) tillage methods on wheat and chickpea yield and yield components and soil physical properties under rainfed conditions in kermanshah (n: 34°19', e: 47°17'), some experiments were performed in sararood dryland agricultural research station during three cropping seasons (2011-2014). in the f...

Subsoil compaction can result in unfavourable soil physical conditions and hinder the root growth of maize. The effects of deep tillage and conventional tillage on soil physical properties and root growth of maize were studied during 2010–2011 at two sites (loam at Hebi and clay at Luohe) in central China. The results showed that soil penetration resistance, bulk density, water content and root...

Rice receives a large amount of water during land preparation and the growing period, causing poor crop water productivity and lower net benefits. In wheat, excessive tillage operations delay its sowing, resulting in low yields and net returns. Dry seeding of rice and zero tillage in wheat can be expected to reduce water inputs and tillage costs compared with the conventional system of rice-whe...
