ALOE VERA is an evergreen perennial plant that was believed to have originated from the Arabian Peninsula some 6000 years ago. Generally, this plant grows in the wild where the climatic conditions are tropical in nature. This plant is stemless and attains a height in the range of 60 to 100 cm. The leaves of this plant are either grayish-green or green with thick flesh inside. The leaves are serrated with small white teeth. The fleshy substance inside the leaves has a bad odor and is bitter to taste. The flowers of the plant are yellow in color and are not used for medicinal purposes. This plant is Succulent in nature that is, it has the ability to close the stomata to avoid loss of water through evaporation, thereby surviving drought conditions. It originated as an ornamental plant but now its cultivation is in demand due to its unending list of medicinal properties. Though this plant originated in the Arabian Peninsula it first gained popularity in the United States. ALOE VERA has been used in various forms like gel, juice, creams, raw, etc. ALOE VERA is ready to use medicine that can be cultivated in the kitchen garden. The life of an Aloe plant is considered to be 12 years. The chemical constituents of the ALOE VERA plant are either obtained from the gel or the latex leaf lining. The gel has polysaccharides, vitamins (A, C, E), amino acids, plant sterols, salicylic acid, magnesium, zinc, calcium, glucose, and cholesterol. Whereas the latex leaf lining has anthraquinone glycosides (aloin, Aloe-emodin, and barbaloin). The gel of ALOE VERA has 99% water and a pH of 4.5. There are many compounds present in ALOE VERA, which account for different properties of the plant.
This plant is known to have 240 different species and hybrids of which only a few are recognized to have medicinal properties and are cultivated. National Botanical Plant Genetic Resource, ICAR, Delhi has released the plant varieties with high aloin content (20.7- 22.8%)
The Central Institute of Medicinal and Aromatic Plants, Lucknow released the AL-1 species which is used for commercial cultivation. These species are estimated to have four harvests.
The other commercial cultivated varieties are Aloe barbednsis, Aloe chinensis, Aloe perfoliata, Aloe vulgaris, Aloe indica, Aloe littoralis, and Aloe Abyssinia.
This plant is highly adaptable to various climatic conditions but should be protected from frost and shade. March – June is the best time for the cultivation of the crop as it needs bright sunlight. The ideal temperature range for ALOE VERA farming is 25 – 40˚C. The lower annual rainfall required for ALOE VERA farming is 50 to 300 mm. The soil that best suits the plant is dry sandy soil. But the species is expected to grow well on loamy, light, coastal sandy, and black cotton soils. The plant can resist high pH, sodium, and potassium values in the soil, but the ideal pH level ranges from 7 to 8.5.
ALOE VERA plants produce offshoots at the base close to the soil level and these can be used for propagation. These offshoots are put in a mixture of sand, charcoal, and potting soil. A young ALOE VERA plant can also be used for propagation purposes. The area where leaves grow actively is chosen and is carefully removed. The leaf is then dipped in the rooting hormone and left at room temperature for 2 to 3 days such that the end dries up and forms call us. This leaf is now ready to be planted in a pot with a well-prepared potting mixture. The plant is lightly watered and kept under indirect light. It takes several weeks for the plant to start rooting.
Aloe Vera Farming Project Report – Land Preparation And Sowing For Aloe Vera Farming:
The roots of this plant do not penetrate deep into the soil; therefore soil distribution should not be too deep. The soil can be given 1 – 2 ploughings and levelling can be done. Cow dung manure @ 25 tonnes/ha is added to the soil during the land preparation. Ridges and furrows are made with a minimum distance of 45 cm. 15-18 cm of the plant rhizome cutting size planted such that only two-thirds of the portion is below the ground. The plant to plant and row to row spacing is 60 x 60 cm. One hectare of land approximately requires 15,000 rhizomes for plantation.
This plant doesn’t require much water. The farming of ALOE VERA can be done in both rainfed and irrigation conditions. 4 to 6 irrigation cycles are required annually for proper growth and yield of the plant. First irrigation is done soon after planting and light irrigation is done after harvesting the leaves. The plant is not tolerant of waterlogging.
This plant is mainly cultivated as an organic crop because it finds its use in medicines and health care. Farm Yard Manure (FYM) @ 12 tonnes/ha is used as a fertilizer to the crop. During the planting when pits are prepared vermicompost @ 2.5 tonnes/ha and wood ash can be used. Sometimes ammonium nitrate is used as an additional supplement for producing higher yields. The manual weed control mechanism is preferred.
Initially, infected leaves should be removed and destroyed. Termites can be controlled by giving the plant light irrigations. Mealybug causes the leaf to turn yellow and wither off, this can be controlled by the application of methyl parathion @ 10 ml or quinalphos @ 20 ml mixed in 10 liters of water. Black and brown spots on the leaves can be controlled by avoiding low temperatures and moisture. Defoliation, dieback, twig cankers, blotches, anthracnose, and shoot blight can all be controlled by spraying 70% of neem oil.
Aloe Vera Farming Project Report – Harvesting In Aloe Vera Farming:
The commercial yield is obtained in the second or fifth year of planting. Leaves that have a large base and are healthy are harvested by cutting them at an angle close to the base of the plant. The plant can be harvested a minimum of four times a year. The harvesting is either done in the morning or in the evening.
The yellow colorless juice that oozes out of the cut leaf is drained into vessels that are concentrated by evaporation or by frequent boiling. Hepatic or livery Aloe is an amorphous, opaque waxy substance obtained by either sun drying or concentrating Aloe juice over the fire. The pulp within the Aloe is scraped out, stirred in a blender to form a homogenous mixture which is strained, filtered, and precipitated by adding acetone to it slowly while stirring the mixture. This content is stored overnight and the gel is isolated by centrifugation. The processing of the ALOE VERA has to be done within a few hours of harvest to prevent oxidation.
The average yield of ALOE VERA leaves for one hectare of land is estimated to be 15 to 20 tonnes. If a plant is well irrigated and managed then the yield is higher, i.e. 30 to 35 tonnes per hectare.
The active components in ALOE VERA are:
Some of the biological activities of ALOE VERA are outlined here.
Healing properties: it is believed that the presence of polysaccharides and gibberellins (a growth hormone) interact with the growth factor receptors of the fibroblast and increase the collagen content which in turn increases the breaking strength of the tissue.
Modulates immunity : the compound acemannan found in ALOE VERA leaves tends to increase the number of monocytes, white blood cells, and macrophages which helps to improve the immunity of patients.
Antimicrobial properties: the compounds such as lupeol, salicylic acid, urea nitrogen, cinnamonic acid, phenols, and sulfur are found in ALOE VERA and are antiseptic in nature. All these compounds can prevent the growth of fungi, bacteria, and viruses.
Effect on the skin and mucous membrane: the enzymes present in the ALOE VERA gel accelerate the healing capacity of the skin and mucous membrane. The moisturizing agents within the gel help in the treatment of psoriasis, skin burns, dry skin, wrinkles, and erythema.
UV and gamma radiations: the presence of metallothionein helps the skin to become less sensitive when exposed to UV radiation.
Anti-diabetic properties: ALOE VERA enhances glucose metabolism by an antioxidant mechanism that helps in decreased levels of diabetics.

This miracle plant finds its use in many substances and purposes such as:
The commercial cultivation of ALOE VERA is gaining importance due to its wide presence in various industries such as health, cosmetics, etc. The cultivation of ALOE VERA needs moderate investment but provides high returns. An example of the investment costs and returns for ALOE VERA farming is outlined here. The figures given here are just an estimation of the entire project. The original values may change depending on the location and market value of the items. This report deals with the cost involved in ALOE VERA production in 2 to 5 acres of land. Also, if the land is taken for lease during the farming period, it is expected to incur more investment and the amount of the lease could vary from 25000-50000 Rs annually for one acre of land. The lease charges may also vary from place to place.
