WHO recommends that a copper-bearing IUD, when used as an emergency contraceptive method, be inserted within 5 days of unprotected intercourse. This method is particularly appropriate for women who would like to start using a highly effective, long-acting, and reversible contraceptive method.
Effectiveness
When inserted within 120 hours of unprotected intercourse, a copper-bearing IUD is more than 99% effective in preventing pregnancy. This is the most effective form of emergency contraception available. Once inserted, women can continue to use the IUD as an ongoing method of contraception, or may choose to change to another contraceptive method.
Safety
A copper-bearing IUD is a safe form of emergency contraception. It is estimated that there may be less than 2 cases of Pelvic Inflammatory Disease (PID) per 1000 users (3). (FP Global Handbook). The risks of expulsion or perforation are low.

Manure is an organic substance that increases soil fertility. It is prepared from decomposition of animal excreta & plant wastes. It consists of Organic matter and nutrients essential for the plant. It improves the soil structure by increasing its water holding capacity, and also avoids water logging.
Some of the advantages of using manures are:
- Improves soil texture
- Restore soil with all nutrients
- Increases water-retaining capacity of soil
- Non-toxic
- Eco friendly
- Recycled biological product

The appropriate distance between the seeds are important bcz if seeds are not sown at appropriate distance and will be sown very close to each other then they will be a competetion for space,water and light which results in improper growth of crop plants.

The distance between seed is important because if seeds are not sown at proper distance there will be a competition between the plants for consuming sunlight,water and space which leads to the improper growth of plants and also damages the whole crop.

Methanobrevibacter smithii is a single-celled microorganism from the Archaea domain. M. smithii is a methanogen, and a hydrogenotroph that recycles the hydrogen by combining it with carbon dioxide to methane. Methanogenesis or biomethanation is the formation of methane by microbes known as methanogens. Organisms capable of producing methane have been identified only from the domain Archaea, a group phylogenetically distinct from both eukaryotes and bacteria, although many live in close association with anaerobic bacteria.

Outbreeding refers to matings between individuals from different populations, subspecies, or species whereas hybridization is the process of crossing two genetically different individuals to result in a third individual with a different, often preferred, set of traits. Plants of the same species cross easily and produce fertile progeny. Such plants are referred to as cross-pollinated plants.

Inbreeding refers to mating of related individuals. It results in a decline in survival and reproduction (reproductive fitness), known as inbreeding depression, in most species of plants and animals. Outbreeding refers to matings between individuals from different populations, subspecies, or species. Plant hybridization is the process of crossbreeding between genetically dissimilar parents to produce a hybrid. It frequently results in polyploid offspring. In biology, outbreeding depression is when crosses between two genetically distant groups or populations results in a reduction of fitness. The concept is in contrast to inbreeding depression, although the two effects can occur simultaneously.

Inbreeding depression stands for the inability of an organism to reproduce because of reduced fertility strength. The process leads to depreciated productivity. Inbreeding among same group in successive generation leads to the decreased productivity and fertility.
Inbreeding itself don’t provide much variation but it holds some advantage as-
1. Superiority is maintained throughout generation
2. Pure line or pure breeds can be obtained.
