Pearl millet, also known as bajra, is a type of grain that is widely grown in arid and semiarid regions of Africa and Asia. It is a staple food in many countries, including India, and is often used to make rotis, chapatis, and other flatbreads. Pearl millet is a good source of nutrients, including protein, fiber, and minerals such as iron and zinc.
Further, it is relatively drought-resistant, making it an important crop in areas with limited access to irrigation. Pearl millet has a nutty flavor and can be used in a variety of dishes, including porridge, bread, and even desserts. It is also sometimes used as feed for livestock. It is a member of the grass family and is closely related to other millet species, such as foxtail millet and proso millet.
Etymology
The word “millet” is derived from the Latin milium, which means “grain.” Pearl millet gets its name from the small, round seeds, which are similar in size and shape to pearls. The plant is also sometimes called “bajra” in India and “bulrush millet” in the United States.
Further, Pennisetum glaucum is the scientific name for pearl millet. The genus name “Pennisetum” is derived from the Latin words “penna,” meaning “feather,” and “seta,” meaning “bristle.” This refers to the feathery appearance of the plant’s inflorescence, or flowering structure. The species name “glaucum” is derived from the Latin word “glaucus,” which means “grayish-blue.” This refers to the color of the plant’s leaves and stems.

Botanical description of pearl millet
The pearl millet plant is an annual grass that grows to a height of 1-2 meters (3-6 feet). It has a robust, upright stem and long, slender leaves that are typically green or bluish-gray in color. The leaves are arranged in a spiral pattern around the stem and are typically 30-50 centimeters (12-20 inches) long and 1-2 centimeters (0.4-0.8 inches) wide. The leaves are attached to the stem by a sheath, which is a tubular structure that encloses the base of the leaf. The sheath is typically open at the top and closed at the bottom, and it serves to protect the base of the leaf and help the plant retain moisture.
The plant produces clusters of small, inconspicuous flowers that are arranged in a terminal inflorescence, or flowering structure. The inflorescence is a spike-like structure that is typically 20-30 centimeters (8-12 inches) long and consists of numerous small flowers arranged in rows along a central axis. The flowers are typically green or yellow in color and are surrounded by small, leaf-like bracts. The bracts are typically green or purple in color and help to protect the flowers.
Each flower consists of a calyx, which is a group of small, green or yellow sepals that enclose the flower bud, and a corolla, which is a group of small, green or yellow petals. The calyx and corolla are attached to a receptacle, which is a structure that supports the flowers and seeds. The receptacle is typically elongated and cylindrical in shape, and it is surrounded by a ring of small, leaf-like bracts.
The flowers are followed by small, round seeds that are similar in size and shape to pearls, hence the name “pearl millet.” The seeds are typically 3-5 millimeters (0.1-0.2 inches) in diameter and are surrounded by a hard, outer coating. The seeds are typically yellow or brown in color and are contained within a seed head, which is a spiky structure that is formed from the dried flowers and bracts.
History of pearl millet
The origins of pearl millet can be traced back to ancient Africa, where it was first domesticated around 4,000 years ago. The plant is native to the Sahel region of Africa, which stretches across the continent from Mauritania in the west to Sudan in the east. It is believed that pearl millet was first domesticated in this region and then spread to other parts of Africa and Asia through human migration and trade.
There is evidence that pearl millet was an important crop in ancient Africa, particularly in the Sahel region. It is mentioned in ancient texts and depicted in ancient art, and it has been found at archaeological sites in Africa and Asia. Pearl millet was an important food source for many ancient civilizations and played a significant role in the culture and economy of these societies.
Over time, pearl millet has undergone significant evolution through the process of domestication and cultivation. It has been selectively bred for various traits, such as increased yield, disease resistance, and improved nutritional content. Today, pearl millet is an important food and feed crop that is widely grown in many parts of the world, particularly in Africa and parts of Asia.
In terms of its biological ancestors, pearl millet is believed to have evolved from wild grasses that were native to the Sahel region of Africa. It is closely related to other millet species, such as foxtail millet and proso millet, as well as other members of the Pennisetum genus, such as napier grass and elephant grass. In many parts of the world, pearl millet is an important cultural and economic commodity, and it plays a significant role in the livelihoods and wellbeing of many people around the world rely on pearl millet as a source of food and income.
Genetics of pearl millet
Genetically, pearl millet is a diploid species, which means that it has two copies of each chromosome in its cells. The basic chromosome number for pearl millet is 2n = 14, which means that it has 7 pairs of chromosomes. However, there is also evidence of higher ploidy levels in some pearl millet varieties, with some studies reporting the presence of triploid (3n = 30) and tetraploid (4n = 40) individuals.
Like all living organisms, pearl millet has a genome, which is the complete set of genetic material present in its cells. The genome of pearl millet is relatively large, with an estimated size of about 730 million base pairs.
Studies of the genomic ancestry of pearl millet have revealed that it is a hybrid species, resulting from the crossing of two ancestral grass species. This hybridization event is thought to have occurred around 4000 years ago in Africa, and has contributed to the adaptability and diversity of pearl millet.
Pearl millet is known to have a high level of genetic diversity, which is thought to be due to its wide range of adaptation to different environments and its long history of cultivation. This genetic diversity has been exploited by plant breeders to develop improved varieties of pearl millet with desirable traits such as higher yield, improved disease resistance, and better nutritional content.
Genomic studies of pearl millet have provided valuable insights into the genetic basis of important agronomic traits, such as grain yield and drought tolerance. These studies have also helped to identify genes and genetic pathways that are involved in the development and function of various plant organs and processes, including photosynthesis, stress responses, and plant-microbe interactions.
Cultivation and production technology of pearl millet
Pearl millet (Pennisetum glaucum) is highly adaptable and able to tolerate extreme environmental conditions, making it an important crop for food security in many parts of the world. Cultivation of pearl millet typically involves the following steps:
Selection of seed and soil
Pearl millet seeds should be chosen based on their germination rate, vigor, and resistance to pests and diseases. The soil should be well-drained and have a pH of 6.0-7.5. Pearl millet can be grown in a wide range of soil types, but it performs best in sandy loam or loamy soils with good fertility. In order to optimize the growth and yield of pearl millet, it is important to select a variety that is well-suited to the local climate and soil conditions.
Preparation of the field
The field should be plowed and harrowed to create a smooth, uniform seedbed. It may also be necessary to apply fertilizers and lime to adjust the soil pH and nutrient levels. The recommended rate of fertilization for pearl millet is 50-100 pounds per acre of nitrogen, 20-40 pounds per acre of phosphorus, and 40-80 pounds per acre of potassium. These nutrients can be applied in the form of organic matter, such as compost or animal manure, or in the form of chemical fertilizers.
Planting
Pearl millet seeds are typically sown using a drill or seed planter, at a depth of about 1-2 inches. The recommended seed rate is 5-10 pounds per acre, depending on the seed size and the desired plant population. Pearl millet can be sown at different times of the year, depending on the climate and the desired harvest date. In cooler climates, it is usually sown in the spring, while in warmer climates it can be sown in the fall or winter. The timing of planting should be chosen to take advantage of optimal weather conditions for germination and growth.
Irrigation
Pearl millet plants require regular watering to support their growth and development. Irrigation should be applied as needed to keep the soil evenly moist, but not waterlogged. In areas with limited water resources, pearl millet can be grown using rainwater or irrigation from sources such as wells, streams, or ponds. The amount of irrigation water required will depend on factors such as the climate, soil type, and stage of plant growth. In general, pearl millet requires about 20-30 inches of water per growing season.
Weeding
Pearl millet plants can be sensitive to competition from weeds, so it is important to keep the field free of weeds through cultivation or herbicide application. Weeds can be controlled through mechanical means, such as hoeing or plowing, or through the use of herbicides.
Harvesting
Pearl millet plants are usually ready for harvest about 3-4 months after planting, depending on the variety and the growing conditions. The plants are typically harvested using a combine harvester, which cuts the plants and separates the grains from the stalks. The harvested grains are then cleaned, dried, and stored for use as food or feed. The yield of pearl millet can vary widely, but it is typically in the range of 1-3 tons per acre.
