Soil Carbon Dioxide Emission as Influenced by Irrigation, Tillage, Cropping System, and Nitrogen Fertilization
Soil and crop management practices can influence CO2 emission from crop and grasslands and therefore on global warming. We examined the effects of two irrigation systems (irrigated vs. non-irrigated) and six management practices [no-till malt barley (Hordeum vulgaris L.) with 67 or 134 kg N ha (NTBFN), notill malt-barley with 0 kg N ha (NTBON), conventional-till malt barley with 67 or 134 kg N ...
متن کاملTotal Dry Matter Production of Potato, Mungbean and T. Aman Rice as Influenced by Nutrient Management of Potato-mungbean-t. Aman Rice Cropping Pattern
A field experiment was conducted at the Regional Wheat Research Centre (RWRC) of the Bangladesh Agricultural Research Institute, Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08 with the objective to find out the optimum nutrient management practice on total dry matter production (above ground part) of each component crop of potatomungbean-t. aman rice cropping pattern. Tw...
متن کاملChanges in Soil Physical Properties and Crop Productivity as Influenced by Different Tillage Depths and Cropping Patterns
A series of field experiments was conducted at BARI central farm to observe the changes in soil densities, moisture retentive properties, and crop productivity as influenced by different tillage depths and cropping patterns. The tillage depth showed significant effect on wheat yield. Grain yield of wheat significantly increased from 2.86 t/ha (minimum tillage depth) to 5.33 t/ha (tillage depth ...
متن کاملNonlinear response of N2O flux to incremental fertilizer addition in a continuous maize (Zea mays L.) cropping system
The relationship between nitrous oxide (N2O) flux and N availability in agricultural ecosystems is usually assumed to be linear, with the same proportion of nitrogen lost as N2O regardless of input level. We conducted a 3-year, high-resolution N fertilizer response study in southwest Michigan USA to test the hypothesis that N2O fluxes increase mainly in response to N additions that exceed crop ...
متن کاملGreenhouse Gas Flux and Crop Productivity after 10 Years of Reduced and No Tillage in a Wheat-Maize Cropping System
Appropriate tillage plays an important role in mitigating the emissions of greenhouse gases (GHG) in regions with higher crop yields, but the emission situations of some reduced tillage systems such as subsoiling, harrow tillage and rotary tillage are not comprehensively studied. The objective of this study was to evaluate the emission characteristics of GHG (CH4 and N2O) under four reduced til...
