The majority of our population depends on agriculture for their livelihood.For sustained livelihood,one should undertake mixed farming,intercropping and integrated farming practices,for example,combine agriculture with livestock/poultry/fisheries etc.
Different crops require different climatic conditions, temperature and photoperiods for their growth and completion of their life cycle.
There are some crops which are grown in rainy season called the kharif season from the month of June to October and some of the crops are grown in the winter season called the rabi season from November to April.
Paddy, soyabean,pigeon pea etc are kharif crops.
Whereas wheat, gram,peas, mustard, etc are rabi crops.
We can divide farming into three stages.
- First is the choice of seeds for planting.
- The second is the nurturing of the crop plants.
- The third is the protection of the growing and harvested crops from loss.
The major groups of activities for improving crop yields can be classified as
- Crop variety improvement
- Crop production improvement
- Crop protection management
This approach depends on finding a crop variety that can give a good yield.
One way of incorporating desirable characters into crop varieties is by hybridization.
Another way of improving the crop is by introducing a gene that would provide the desired characteristic. This results in genetically modified crops.
Some of the factors for which variety improvement is done are
- Higher yield.
- Improved quality
- Biotic and abiotic resistance
- Change in maturity duration
- Wider adaptability
- Desirable agronomic characteristics
- The idea that we can improve the inherited characterstics of crop species is fundamental.very few of the plants we use are unmodified wild plants.most of them have been modified to make them easier to grow and harvest,and to increase the quality and quantity of the desired product.
- We will see many examples of crop improvement this semister.Here are some basic methods used
Production practices can be at different levels. They include 'no cost' production,'low cost' production and 'high cost' production practices.
Nutrient management:Nutrients are supplied to plants by air, water and soil. There are sixteen nutrients which are essential for plants. Amongst these six are required in large quatities and are therefore called macronutrients. The other seven are used in small quantities and are therefore called micro-nutrients.
Manure:It is useful in protecting our environment from excessive use of fertilizers. Using biological waste material is also a way of recycling farm waste. Fertilizers:It supplies nitrogen,phosphorous and potassium.They are used to ensure good vegetative growth,giving rise to healthy plants.Fertilizers are a factor in the higher yields of high-cost farming. Irrigation:Many measures are used to bring more and more agricultural land under irrigation. These include well,canals,rivers and tanks. Cropping patterns:The growing of different crops on a piece of land in a pre-planned succession is known as crop rotation. Depending upon the duration, crop rotation is done for different crop combinations.
Removal of weeds from cultivated fields during the early stages of crop growth is essential for a good harvest.
Weed control methods also include mechanical removal. Preventive methods such as proper seed bed preparation, timely sowing of crops, intercropping etc also help in weed control.
Preventive and control measures are used before grains are stored for future use. They include cleaning of the produce before storage, proper drying in the sunlight, and then in the shade, and fumigation using chemicals that can kill pests.
It is a scientific management of animal livestock. It includes various aspects such as feeding, breeding and disease control.
It is done for two purposes- milk and draught labour for agricultural work such as tilling, irrigation and carting.
Milk production females are called milch animals, while the ones used for farm labour are called draught animals.
The food requirements of diary animals are of two types:
- Maintenance requirement, which is the food requirement.
- Milk producing requirements which is the type of food required during lactation.
Poultry farming is undertaken to raise domestic fowl for egg production and chicken meat.
Poultry fowl suffer from a number of diseases caused by virus, bacteria, fungi, parasites, as well as from nutritional deficiencies.
Fishing can be done both by capture and culture of fish in marine and freshwater ecosystem.
As marine fish stocks get further depleted, the demand for more fish can only be met by such culture fisheries, a practice called mariculture.
All the food in the pond without competing with each other, is eaten by these fishes. This increases the fish yield from the pond.
Bee-keeping needs low investments, farmers use it as an additional income generating activity. In addition to honey,the beehives are a source of wax which is used in various medicinal preparations.
The value or quality of honey depends upon the pasturage or the flower available to the bees for nectar and pollen collection.
