Plough: This is used for tilling the ground, fertilizing crops, getting rid of weeds, scraping the ground, etc. A pair of bulls or other animals are used to pull this tool, which is composed of wood or iron.
Hoe: This straightforward tool is used to clear weeds from the soil and loosen it.
Cultivator: Today, a tractor-driven cultivator is used for ploughing. It saves time and labour.
SOWING
Before sowing, high-quality seeds are chosen. Clean, nutritious, and of a nice variety, good quality seeds are those. If we are given seeds to choose from, we must put all of the seeds in a pail of water and thoroughly agitate them. Few seeds will float in the water, and the majority of the seeds will settle at the bottom of the bucket. Seeds with damage become hollow and lighter as a result. They float on water as a result.
Seed Drill
In modern times, tractors’ hoes are utilized to spread seeds. This device evenly distributes the seeds at the correct depths.

Royal Poinciana: Classification, History, Occurrence, Characteristics, Phytoconstituents, and Economic Importance

Leave a Comment / Botany, Plants /

The Generic name “Delonix” comes from the Greek words “delos” (visible) and “onyx” (claw) about the flower’s prominently clawed petals. The Latin word “regis” (meaning “royal, regal, and magnificent”) is the source of the particular name “regia” (Singh et al., 2014). Nature has long been a vast source of therapeutic compounds dating back to the Stone Age. For both traditional and modern medicine, plants have historically been the most abundant source of raw ingredients. Phytochemicals are largely responsible for plants’ therapeutic efficacy. The flame of the forest or flame tree is a species of almost evergreen tree with broad, open, umbrella-shaped crowns. They are essentially planting metabolites that are produced independently in every area of a plant’s body and that have definite physiological effects on mammals (Hait et al., 2018). It is known by a variety of names in every region and nation, including Chura (Bengali), Radha (Bengali), Royal, Flamboyant, Poinciana (French), Gulmohar, Shima, sunkesula (Hindi), mayirkonrai, Punjabi (Tamil), Flamboyant flame tree, Gold mohur, flame tree, Peacock flower, Gul mohr, and Royal poinciana (English). This tree needs light to flourish, but in the dark, it develops slowly and unevenly. It thrives in areas with both abundant and infrequent rainfall. Only in regions with a long and noticeable dry season are trees deciduous (Sharma and Arora, 2015).

CELL: Discovery, Structure, Functions, Questions, and Answers for Class 8th Science Chapter 8 NCERT/ CBSE

Leave a Comment / Cell and Molecular Biology, General Questions /

Every known living entity has a cell as its fundamental structural and functional element. It is frequently referred to as the foundation of life since it is the tiniest piece of life that may be considered a living entity. There are roughly 10 trillion cells in an adult human. Only under a microscope can one see the majority of plant and animal cells, which range in size from 1 to 100 m. In 1665, Robert Hooke found the cell. All organisms are made up of one or more cells, According to the cell theory, which was first put forth in 1839 by Matthias Jakob Schleiden and Theodor Schwann. It also states that all cells are descended from preexisting cells, that vital functions of an organism take place within cells, and that all cells contain the genetic information required to control cell functions and pass information to the next generation of cells.

Japanese Maple Plant: Classification, Distribution, Characteristics, and Diseases

Leave a Comment / Botany, Plants /

Japanese Maples are known to be susceptible to Verticillium, Fusarium, Botrytis, Pythium, Pseudomonas, and Anthracnose fungal diseases. All deteriorated plant tissue, particularly vascular tissue, impairs normal plant function and frequently causes whole or partial plant death. The bulk growing of seedlings or asexual cuttings is the main cause of fungal illness (Vertrees, 2001).
Numerous types of woody plants are known to be afflicted by the soil-borne disease verticillium. Young twigs will typically wilt and die back, which are ambiguous signs that resemble leaf blight, leaf scorch, and general root disturbance. Because propagation instruments frequently spread verticillium, careful sterilising is crucial. Two fungi known as botrytis and fusarium are known to infect large groups of seedlings and cause “damping off.” Both diseases also target more mature plants.
At or below ground level, Pythium and Pseudomonas damage budding seedlings, entering fresh tissue. The most frequent causes of Pythium and Pseudomonas losses are warm, humid springs and summers, with seedlings developing in alkaline to neutral pH conditions, particularly if the soil is thick or abnormally rich in nitrogen. Anthracnose is a disease that overwinters on dead branches and twigs and infects freshly growing leaves in the spring.

Characteristics of Laceleaf Plant
1. Anthurium belongs to the Araceae family, which has 108 genera and about 3750 monocotyledonous species.
2. Araceae is a family of flowering plants that includes the species Anthurium andraeanum.
3. It is a perennial herbaceous plant that is grown for its showy, heart-shaped inflorescence, which lasts for a very long time.
4. The species is indigenous to Ecuador and Colombia. Several uses for Anthurium andraeanum species are landscaping plants, flowering potted plants, and cut flowers.
5. Slow-growing perennial Anthurium andraeanum needs damp, shaded environments like those found in tropical rainforests.
6. The vase life of an anthurium is between 14 and 28 days. It is a modified leaf (spathe) with several little botanical flowers on a pencil-like protrusion (spadix).
7. The cultivars of Anthurium andraeanum have long held a prestigious place in the world’s floriculture trade.
8. Both sexual and asexual methods can be used to spread Anthurium andraeanum. However, vegetative propagation strategies tried on these plants have not yielded positive results, and tissue culture techniques now appear to be an alternative to boost the output of anthurium, which is typically propagated by seeds.
9. Because of cross-pollination and heterozygous progeny, seed propagation is not preferred. Additionally, it is hindered by the seeds’ poor viability and low germination rate.
10. Anthurium has been successfully micropropagated using a variety of explants. Pierik et al. published the first report on the tissue culture of Anthurium (1974). Both direct shoot regeneration from lamina explants and adventitious shoot production from callus were successful in regenerating Anthurium andraeanum. Nowadays, there are many people doing floriculture all over the world.
11. Both potted plants and cut flowers made from anthurium are offered, but the cut flower market is substantially larger. Among tropical flowers, the trade value of anthurium is second only to that of spray tropical orchids, and the size of the global anthurium import market is believed to be greater than US$ 20 million yearly.
12. Micropropagation is a factor in the trade-in anthuriums’ consistent growth. Due to the relatively costly cost of micropropagation, anthurium flowers are out of the reach of the average person.

Beer is created through the fermentation of starch with the addition of yeast and malted cereal starch, particularly barley, corn, rye, wheat, or a blend of various grains. Hops are typically used to add flavour to the beer. It has an alcohol content of 4–8% and 100 mL of it has between 28 and 73 kcal. Distilling ethanol from the fermentation of grains, fruits, or vegetables produces distilled alcoholic beverages. They are manufactured from fermented cereal and potato mashes, sugarcane juice, molasses, and barley and rye malt. Distilled alcoholic beverages typically contain between 40% and 60% alcohol.

NATURAL RESOURCES
Resources are anything that humans may utilise to fulfil their needs and desires. Natural resources are those that are directly accessible from nature and can be used by humans.
A straightforward definition of a natural resource is “Resources that exist independently of human intervention.”
Natural resources, according to WTR (2010), are “stocks of materials existing in the natural environment that are both scarce and economically usable in production or consumption, either in their raw state or with a minimal amount of processing.”

Oenology is the study of wine and winemaking. Traditionally, A person who produces wine is referred to as a vintner or winemaker. Using a variety of yeasts, crushed grapes can be fermented to create wine, an alcoholic beverage. Apple and berry fruits are sometimes employed in the production of apple wine and elderberry wine. The starch-based ingredients, such as rice and barely, can also be utilised to make beer-like wine. However, grapes are the primary ingredient in wine production all over the world. Some of the world’s largest wine producers include the US, France, Italy, and Spain. The production of wine around the globe is dominated by Italy, which produces approximately 5000 tonnes annually, and France, which produces around 4700 tonnes annually, which ranks second. Wines can be classified as Red, White, Sweet, Sparkling, or Deserting. Typically, the alcohol content of red, white, and sparkling wines ranges from 10 to 14 percent by volume, while that of dessert wines ranges from 15 to 20 percent. Producing still wine (without carbonation) and sparkling wine are the two broad categories into which winemaking can be separated (with carbonation – natural or injected)
