SEEDERS: PRINCIPLES AND CHARACTERISTICS

Definition, characteristics and factors to be assessed for the work of the different machines designed for mechanized sowing. Here, the principles and basic characteristics of the machines dedicated to planting crops are outlined.

SEEDER BENEFITS

The seeders are responsible for placing the correct amount of seeds in the soil and for that reason they become a determining tool in the farming. This agricultural machinery is an extension for producers to carry out their work more efficiently, with effective agricultural practices that contribute to profitability and reduce risks.
In order for it to offer these benefits, it is important that it is kept clean, calibrated and at a good speed to avoid problems when dropping the seeds. This is very important because the success of the culture also depends on the implantation conditions.
In general, seeders are machines with bars and tubes through which the seeds are distributed, at the same time that they open the furrows to place them in the ground. However, these machines can help to place the fertilizer, even simultaneously, with a combination of seeder-fertilizer adding to the soil the nitrogen that the crops need.

INTRODUCTION

The seeder can be defined as a machine that allows regular sowing, either over the entire surface or in equidistant lines and at a uniform depth, of all the grains used in crops. After sowing the seeds must survive from their own reserves until, after germination, the cotyledons emerge outside and the roots digs into the ground and as a seedling, it can carry out photosynthesis. Not all sown grains survive, and that is why the amount of seed used must be greater than the number of plants desired. The factors that affect the selection of the quantity of seed are the species and even the variety to be sown, the germination potential of the seed (measured in the laboratory), the soil and its fertility, the cultivation method and the collection method. It is also necessary to consider the possible formation of scabs, as well as their resistance, not forgetting factors such as diseases, pests and adverse environmental conditions. Perhaps because sowing is one of the cultivation tasks that is better done mechanically than manually, that is why the development of large-crop seeders has led to increasingly sophisticated machines appearing in the market.

The essential parts of a seeder or planter are:

• Frame.
• Hopper.
• Distribution bodies
• Buried parts.
• Complementary bodies.
• Regulatory mechanisms.

Characteristics affecting the frame:

• Great variability of distances between lines.
• Solidity.
• Convenient and quick coupling of the tractor.

Characteristics that affect the distribution:

• The amount of grain sown in each crop line must be identical.
• Scrupulous respect for the desired sowing density.
• Wide margin of regulation of the planting density.
• Versatility regarding the different species and varieties of seeds.
• Integrity of the grain, taking it to the furrow without breaks or deterioration that affects its germination power.
• Variations in ground speed and slopes should not alter the quality of work.
• Precision in the distribution in the case of looking for a monograin seeding.
• Possibility of operation with very little amount of seed.
• Easy cleaning.

Features affecting the hopper:

• Ease of access for filling.
• Possibility of completely emptying it to avoid seed mixtures.
• Ability to view and control the content level.
• Presence of agitators.
• Presence of spacers.

Characteristics that affect buried parts:

• Adaptability to different types of soils.
• Uniformity in the depth
• Opening and closing the sowing furrow
• Abrasion resistance

Characteristics that affect the whole machine:

• Existence of markers
• Good manoeuvrability
• Ease of transport
• Simplicity of mechanisms
• Solidity
• High work capacity.
• Competitive price
• To achieve this in the sowing it is important to place the grain in favorable conditions for its germination, for this, a good preparation of the soil is essential, which can only be done with a number of tasks carried out in time and rationally.
• Generally, it can be said that the soil is optimally prepared for sowing when 40% of the particles have a smaller diameter than the sown grains.

ZERO-TILLAGE SEED DRILLS

Traditional sowing technologies require soil tillage. However, newer conservation agriculture techniques recommend that the use of machines not be carried out and reduced. With this, the soil is kept more fertile and machinery is replaced less frequently, representing less expense for the producer.
No-tillage drills should be lightweight and commensurate with the depth of planting required for good seed coverage. It is also important that they can move between variations in the surface of the earth and that they can move between the residues of the organic cover without blocking.
Another recommendation of conservation agriculture is crop rotation, a technique that has been used successfully in regions such as Pakistan, where, with multicultural no-till seeders, they managed to sow 2.2 million hectares of rice and wheat in the period of 2016- 2017.
According to the International Maize and Wheat Improvement Center (CIMMYT), direct sowing of rice in unploughed and non-flooded fields improved plant density and saved 25% of the water used in this crop.

This success story shows that the seed, the soil and the seeder are the most important trilogy for the farmer. Hence, it is extremely important to choose the most suitable for the conditions of each terrain.
