Biogas plant
The dead body of humans or dead plants gets decomposed in soil in natural way. Decaying procedure is done by bacteria, fungus, virus etc. In decaying procedure gas is produced. This gas is known as biogas. This procedure can be done in air and as well as without air.
Without air condition the gas which is produced through organic elements contains 50-55% methane gas, 30-35% carbon dioxide gas and ample quantity of nitrogen, hydrogen sulphide, oxygen etc. In 1900s in India in the Leprosy museum situated in Matunga, Mumbai the plant is installed which produces biogas from dung. Then the technique for production of gobar gas with dung is developed. Among these two techniques gets famous:
- Floating drum model or K.V.K model
- Deenbandhu model or Fix dome model
These plants produce odorless methane gas which is produced from the blue flame and gives suitable energy which helps in preparing food in half time. After preparing food, other tasks can also be taken from the gas:
- Using as a light at night time
- By using diesel engine will help to save 80-85% of gas. With diesel machine water pumpsets, flour grinding machine etc. can also be run.
- For producing electricity.
- For every work where energy is required for example welding etc.
Seed germination through newspaper method
Newspaper method is very effective for seed germination. By this method seeds germinate within 2-3 days. Later it is beneficial to make the place in the field and water it immediately after sowing. Fold the paper four times and then dip the newspaper in the water. Afterthat place the seeds at some distance on the newspaper and then roll the newspaper and tie it with thread. When root formation starts then sow them in the soil.
After choosing for Desi or advanced varieties, before seed sowing two things must be kept in the mind, first before sowing do inspection of seeds whether they are good or not by doing seed germination and second if the seeds are good then sowing must be done after doing seed treatment.
Germination inspection: It is done in the same way as done in houses for pulse germination. Soak the seeds in water for some hours (this method gets changes according to climate and type of seeds, Chick pea seeds needs to be soaked for 7-8 hours in summer season. In winter season it will take more time for germination. The seeds having thin layer takes less time for germination).Then the seeds are placed on thick cotton cloth and kept in the dark but in airy place. Maintain the moisture level. If the germination percentage is less than 70-90% then change the seeds. If seeds exchange is not possible then increase the number of seeds.
Another easy method for germination inspection is to fold the paper four times and then dip the newspaper in the water. Without using lime, place 50-100 seeds on newspaper at some distances and then fold the newspaper. Then close both the corners of the newspaper with thread loosely. And then again soak the newspaper in water. Drain out the extra water. After removing excess water put the newspaper in polythene bag and hang it internally in the house. After 3-4 days open the newspaper and count the number of seedlings.
The seed inspection procedure should be done before 2-3 weeks of sowing so that if seeds are needed to be changed then they can be changed on time.
