Rotary Tillage

Rotary Tillage

 

(rototilling), the loosening and inverting of soil to a depth of 20–25 cm with a rotary plow. The soil is broken into pieces by blades or teeth attached to the disks of a rotating drum; it strikes the housing fenders and is broken into small pieces. The result is an even, well-loosened surface. Rotary tillage is used to dress the slice on drained bogs and marshy lands, to bring peat bogs under cultivation, and to improve sod lands in meadows and pastures, as well as in forestry to prepare soil for forest crops, and in vegetable and flower growing to cultivate the soil in hothouses, hotbeds, plots adjacent to hotbeds, and nurseries. The effectiveness of rotary tillage on old plowed land is under study. Rotary tillage is one of the operations involved in extracting peat by the surface-milling method.

The field experiment involved two passes of rotary tillage (2RT at 20 cm), subsoiling (SS at 40 cm), two passes of rotary + subsoiling (2RTSS at 20 and 40 cm respectively), and zero tillage (ZT).

Naresh et al., 2015a found that the infiltration rate was consistently highest with an overall average of 84.7mm [h.sup.-1] (raised bed), lowest at 50.3 mm [h.sup.-1] in conventional tillage (puddling), and intermediate 55.7; 62.2 mm [ha.sup.-1] in rotary tillage and zero tillage.
On 20th August rotary tillage was carried out to crumble large lumps level the fields and improve soil moisture.
The sowing techniques evaluated were broadcasting (T-1), Rotary Tillage Drill (T-2), Zero Tillage Drill (T-3) and Rabi Drill (T-4).
Rotary tillage drill (T-2) gave maximum net income (Rs.36442 ha-1) with a CBR of 1:12.80 compared with rabi drill (T-3) net income Rs.
By using rotary tillage drill wheat sowing can be done in single pass i.e.
The CT treatment was similar to reduced tillage described in the Introduction but the term 'conservation tillage (CT)' was used to distinguish it from rotary tillage (RT).
Treatments were no-tillage (NT), conservation tillage (CT), rotary tillage (RT), and pasture.
Compared with rotary tillage (RT), plough tillage (PT) significantly increased soil CO2 emission rate, and no tillage (NT) significantly decreased the soil CO2 emission rate throughout the wheat growing season.
The 3 tillage practices were plough tillage (PT), rotary tillage (RT) and no tillage (NT), and the corn straw was applied at 7000 kg hm-2 in dry weight.
