Strip-Tillage Production Systems for Tobacco
Conservation tillage production systems for flue-cured tobacco (Nicotiana tabacum L.) have been studied for many years. Inadequate chemical weed control and lack of acceptable pesticide and fertilizer application resulted in consistently lower yields and inferior cured leaf quality. The development …

NO-TILLAGE RENOVATION OF ALFALFA STANDS
<p>The effects of herbicides, timing, and rates on the introduction of alfalfa (Medicago sativa L.) into six stands of alfalfa at varying stages of decline were investigated.</p><p>Alfalfa was seeded on several dates from 25 April through 28 May 1979 with a Tye Pasture Pleaser('R) no-till seeder. …

Conservation tillage methods for cabbage production
… were to assess the applicability of conservation tillage systems for cabbage production. Four tillage systems (conventional tillage, CT; no-tillage, NT; and two types of strip tillage—Ro-till, RT, and chisel plow, CP) and three planting dates (early, mid and late) were compared in 1985 and 1986. …

Conservation tillage machinery for broccoli production
… and reap the other benefits of conservation tillage, a strip tillage machine named FOR2 was designed, developed and tested. FOR2 prepares the seedbed and places the seed in one pass through the field. This thesis reports the qualitative and quantitative evaluation of FOR2 based on result from …

The potential of reduced tillage in Flanders
… decline in SOM and N losses. Conservation tillage (CsT) agriculture was first introduced on a large scale on fields with mainly cereals, soybean and sunflower in the USA, Latin America and Australia as a very effective measure to reduce erosion and store water into the soil (Arshad, 1999; …

Residue, tillage, and nitrogen effects on soils
… practices of nitrogen fertilizer application and tillage, this practice could lower soil organic carbon (SOC), as well as increase erodible sediments and soil compaction. A study was initiated in the 2006 growing season that included combinations of three levels of residue removal (none, partial, …

Corn residue, tillage, and row spacing effects on soybean
… belt, and soybean seed is often planted without tillage into standing corn residue or, if tilled, into a considerable amount of corn residue left on or near the surface. The increase in corn residue with increasing corn yields raises the question about whether corn residue interacts with tillage …

No-tillage squash production on agricultural soil and minesoil
No-tillage establishment into a killed surface mulch on agricultural soil increased marketable acorn squash (Curcurbita pepo L. 'Table Ace’) yield by 29% as compared to a conventional tillage practice. These yield differences are attributed to increased plant population and possible improved water …

Zero tillage for cereal production on forage sods in Manitoba
The effects of zero, minimum and conventional tillage on soil water content, soil compaction and crop growth on a fine-textured soil previously sown to perennial forages was studied over a two year period. The effect of glyphosate, 2,4-D and dicamba, alone or in combination was evaluated for the …

Analysis of Herbicide Incorporation by Tillage Tools Using Image Processing
The effect of tool speed, sweep spacing, and sweep size on the incorporation of herbicides by a field cultivator was studied. A system was developed to quickly and accurately record the distribution of fluorescent dye, which represented the herbicide, after incorporation into the soil. The system …

Effect of tillage on rainfall infiltration and surface depressional storage
Research to evaluate the effects of tillage on rainfall infiltration and surface depressional storage was conducted. A method that generates infiltration, surface depressional storage, detention storage and hydraulic conductivity from data obtained from small field plots receiving simulated …

Effect of tillage system and nitrogen rate on tomato yield
Experiments to evaluate the effects of tillage systems and nitrogen fertilizer rates on fresh market 'Pik Red' tomato (Lycopersicon esculentum Mill.) production were carried out at Blacksburg, Virginia (1981 and 1982) and at Carrasco and Jackson, Uruguay (1981-2). Two tillage systems were used: (a) …

Influence of tillage and mulch on the early growth of corn
… in both 1979 and 1980 to study the effect of tillage and mulch treatments on the early growth of corn plants. The objectives of this research were: (1) to separate and measure the effects of tillage and mulch on early growth of corn, (2) to determine whether observed differences in corn growth …

Tillage and cover cropping effects on soil properties and crop production
… each split in the N_S direction into levels of tillage (NT, no-till vs. Till, chisel till) and further split into sub-subplot treatments of CC rotations (R) arranged in the W-E direction across tillage treatments. Crop yields, CC stand counts in late fall, and spring biomass samples were taken …
