What is the purpose of tillage?
The aim of the tillage is to produce as good a soil condition or tilth as possible for crop establishment and initial shoot and root development. When soil is brought to such a condition ideal for crop growth, it is called seed-bed and is said to be in good tilth.
What is tillage in agriculture?
Conventional tillage involves primary tillage to break, open and turn the soil followed by secondary tillage to obtain seed bed for sowing or planting. With the introduction of herbicides in intensive farming systems, the concept of tillage has undergone radical change:
What is a tractor used for?
Tractor is used for sowing and the wheels of tractor pulverize the row zone. (ii) Zero Tillage: Zero tillage referred as no tillage in which the crop is planted in unprepared soil by opening a narrow slot, trench or band only of sufficient width and depth to obtund proper seed coverage.
What is minimum tillage?
Minimum tillage refers to growing a crop using only that tillage needed for placing the seed at proper depth and then covering them. Thus minimum tillage aimed that reducing tillage to the minimum necessary for ensuring a good seed-bed, rapid germination, satisfactory stands and favorable growing condition.
What herbicides are used under zero tillage?
Commonly used herbicides under zero tillage are parquet and piquet both. (iii) Conservation Tillage: Conservation tillage is a system of tillage in which organic residues are not inverted into the soil such that they remain on the surface as a protective cover against erosion and evaporation losses of soil moisture.
What is stubble mulch?
If stubbles from the protective cover on surface, it is usually referred as stubble mulch tillage. The residues left on the soil surface interfere with seed-bed preparation and sowing operations. Objective: To conserve soil from erosion along with water (moisture).
What is the purpose of primary tillage?
The operations performed to open up any cultivable land with a view to prepare a seed bed for growing crops is known as primary tillage.
What is combined tillage?
Operations simultaneously utilizing two or more different types of tillage tools or implements to simplify, control or reduce the number of operations over a field are called combined tillage. Tillage is performed by tool, implements or machine.
What is the first operation in crop production?
The first operation in production of crop is tillage. It requires higher amount of labour. It is a mechanical manipulation of soil to provide favourable condition for crop production.
Types of tillage
Tillage includes ploughing the fields, harrowing, cultivating, rolling, leveling the land and hoeing and weeding etc. On the basis of these activities, tillage is divided into two parts.
Primary tillage
All the agricultural activities done before sowing seeds and germination in the field are called Primary tillage, it includes ploughing, rolling, leveling the soil, and adding manure etc.
Objectives of primary tillage
To increase the water holding capacity of the soil and conserve moisture.
Secondary tillage
All the agricultural activities after the sowing of seeds in the field are comes under secondary tillage, it includes mainly weeding and hoeing, earthing up and mixing of fertilizers etc.
Definitions related to tillage
Sowing of a crop, without ploughing in the residues of the previous crop, is called Zero Tillage. This method is suitable where weed control is done by chemical method.

Why do farmers use tillage methods?
There are several reasons for using tillage in agriculture. The main objective is to create grooves in the soil that are deep enough to successfully plant and grow crops. Other major objectives of tillage include aerating the soil, incorporating crop residues, and killing weeds.
How does tillage affect soil quality?
While one of the reasons farmers use tillage is to enhance the available nutrients in the soil, recent studies have shown that the process negatively impacts soil quality.
How does tillage impact global warming?
One major downside of using tillage techniques is that the process contributes to global warming. Usually, carbon dioxide is stored within the soil, but the process of churning it up has the impact of released this usually trapped carbon dioxide into the atmosphere, increasing greenhouse gas emissions.
