No-till farming is not equivalent to conservation tillage or strip tillage. Conservation tillage is a group of practices that reduce the amount of tillage needed. No-till and strip tillage are both forms of conservation tillage. No-till is the practice of never tilling a field. Tilling every other year is called rotational tillage.
Happy Seeder is a proposed solution for stubble management after harvesting of the paddy crops. It is similar to a Zero Till Ferti Seed Drill developed by National Agro Industries. [2] [3] Usually, many farmers in Punjab and Haryana burn stubble, which has a severe socioeconomic and environmental impact on the North Indian regions.
Minimum tillage is a soil conservation system like strip-till with the goal of minimum soil manipulation necessary for a successful crop production.It is a tillage method that does not turn the soil over, in contrast to intensive tillage, which changes the soil structure using ploughs.
[10] No-till – plows, disks, et cetera are not used. Aims for 100% ground cover. Strip-till – Narrow strips are tilled where seeds will be planted, leaving the soil in between the rows untilled. [11] Mulch-till - Soil is covered with mulch to conserve heat and moisture. 100% soil disturbance.
In one study, yields were higher in the strip-tilled area than in the area where no-till was practiced. In a low phosphorus site, yield was 43.5 bushels/acre (2,925.5 kg/hectare) in strip-till compared to 41.5 bu/a (2,791 kg/ha) in a no-till system. [7] Yield is comparable to that of intensive tillage systems — without the cost. [8]
The seed drill employed a series of runners spaced at the same distance as the plowed furrows. These runners, or drills, opened the furrow to a uniform depth before the seed was dropped. Behind the drills were a series of presses, metal discs which cut down the sides of the trench into which the seeds had been planted, covering them over.
