Soil Physical Characteristics and Crop Productivity as Affected by Tillage in Rice-Wheat System
Tillage practices significantly influences soil physical characteristics and crop productivity. The infiltration characteristics, bulk density, porosity, penetration resistance, grain yield of rice and wheat were measured under no-till without residue (NT), roto-tillage (RT), and no-till with residue i.e. happy seeder (HS) in rice-wheat cropping system in sandy loam (SL) and loamy sand (LS) soi...
متن کاملTillage, Mulch and N Fertilizer Affect Emissions of CO2 under the Rain Fed Condition
A two year (2010-2012) study was conducted to assess the effects of different agronomic management practices on the emissions of CO2 from a field of non-irrigated wheat planted on China's Loess Plateau. Management practices included four tillage methods i.e. T1: (chisel plow tillage), T2: (zero-tillage), T3: (rotary tillage) and T4: (mold board plow tillage), 2 mulch levels i.e., M0 (no corn re...

could be optimized using modified NT systems (including ST) and starter fertilizer. In Iowa Mallarino et al. (1999) Utilizing conservation tillage practices and increasing fertilizer N found that ST frequently increased early growth but seluse efficiency for corn (Zea mays L.) are necessary for optimizing dom increased corn grain yields compared with NT. growers’ profits and for minimizing loss...
متن کاملIntegrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system
Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...
متن کاملSoil carbon and nitrogen sequestration as affected by long-term tillage, cropping systems, and nitrogen fertilizer sources
Disposal of poultry litter, a widely available organic manure in the southeastern USA because of a largescale poultry industry, is a major concern because of its contamination in surfaceand groundwater through N leaching and P runoff. Application of poultry litter in no-tilled intensive cropping system could increase soil C and N sequestration compared with the conventional-tilled system with i...
