Rice production and minimum tillage

Outlook on Agriculture, 1969
The introduction of new high-yielding varieties and an increased usage of fertilizers and pesticides are beginning to have a significant effect on rice production in Asia. Shortage of water, power and time could, however, limit full exploitation of this new technology.

Water Infiltration Under No-tillage, Minimum Tillage and Conventional Tillage Systems on a Sandy Loam Alfisols

2004, Ottawa, Canada August 1 - 4, 2004, 2004
A study was conducted on a tropical Alfisols on the Teaching and Research Farms of University of Ibadan in order to determine the effect of three tillage (no-tillage, minimum and conventional tillage) systems on infiltration of water in the soil. The experiment was a split-plot design with three replications.

Comparative tillage costs for crop rotations utilizing minimum tillage on a farm scale

Soil and Tillage Research, 1998
Minimum tillage systems have been promoted for their soil conservation benefits, however, profitability is a major factor governing the adoption of soil conserving practices. Under conditions of similar crop productivity and input (i.e., fertilizer and pesticide) use, tillage costs become the key determinant of profitability. Two studies were conducted

Minimum Tillage Fallow Systems for Reducing Wind Erosion

Transactions of the ASAE, 1977
ABSTRACT CLIMATE is the greatest single factor that influ-ences wind erosion control. Much of the Great Plains has insufficient precipitation for profitable annual cropping under present dryland cropping prac-tices. Moisture conservation and residue maintenance should always be considered when contemplating a tillage operation.

Vibratory Furrow Opening Tool for Minimum Tillage Planters

Transactions of the ASAE, 1979
ABSTRACT A vibratory furrow opening tool was designed for use with a minimum tillage row crop planter system. System performance was evaluated in field tests where corn was planted in chemically killed sod. The effective-ness of the vibratory tool was compared to a fluted coul-ter opener based upon measurements of energy input, clod size distribution ...

Minimum tillage and residue retention increase soil microbial population size and diversity: Implications for conservation tillage

Science of The Total Environment, 2020
A global meta-analysis was conducted to evaluate the effect of conservation tillage practices on soil microbial population size [based on microbial count and phospholipid fatty acid (PLFA) measurements], diversity (Shannon index), and microbial community structure.

Landownership and the Adoption of Minimum Tillage: Reply

American Journal of Agricultural Economics, 1985
The comment by Heimlich correctly interprets the definition of the dependent variable, minimum tillage, in our analysis. The term minimum tillage did include the union of minimum tillage and residue management. The abbreviation to minimum tillage may have confused some readers. We appreciate the opportunity to clarify the definition.

MINIMUM TILLAGE REQUIREMENTS FOR SUMMERFALLOW IN WESTERN CANADA

Canadian Journal of Soil Science, 1967
Experiments at seven locations in Western Canada between 1956 and 1961 indicated that three or four tillage operations were usually enough for satisfactory weed control on summerfallow, and generally provided highest yields of grain. Two tillage operations were not sufficient.

Research on minimum tillage, no-tillage and mulching systems and its effects in China

Theoretical and Applied Climatology, 1996
Minimum tillage, no-tillage and mulching have been broadly used in modern Chinese agricultural production in the past 20 years. The application area has reached 12.34 million hectares, and a corn, soybean, rape, wheat, peanut and rice have been involved in these tillage systems.

Landownership and the Adoption of Minimum Tillage: Comment

American Journal of Agricultural Economics, 1985
In a recent paper, Lee and Stewart (hereafter LS) estimated adoption of minimum tillage as a function of land tenure, farm size, and erosion hazard. They concluded that full-owner operators and owners of smaller farms have lower adoption rates than do other groups.
