Litchi (Litchi chinensis) is a delicious juicy fruit of excellent quality. Botanically it
belongs to Sapindaceae family. Litchi fruit is famous for its attractive red colour, excellent
quality characteristics and pleasant flavor.
Soil and climate:
Litchi is a sub-tropical fruit and thrives best under moist sub-tropical climate. It usually
prefers low elevation and can be grown up to an altitude of 800 m. (m.s.l.). Deep, well drained
loamy soil, rich in organic matter and having pH in the range of 5.0 to 7.0 is ideal for the crop.
Litchi cannot tolerate frost during winter and dry heat in summer. The temperature should not
go beyond 40.5 0C in summer and below freezing point in winter. Prolonged rain may be harmful
especially at the time of flowering, when it interferes with pollination.
Cultivars:
A large number of varieties are grown in different parts of India. Bambia, Ellaichi,
Muzaffarpur, Seedless early, Seedless late, Shahi, Pottee, Rose scented, China, Purbi, and Kasab
are the suitable varieties for NE region.
Propagation:
Air layering is the most common method of propagation. Select healthy and vigorous one
year old twigs and remove 2 cm wide ring of bark just below a bud. IBA or Rooton may be
applied at cut portion for early and more rooting. The cut is surrounded by mud ball containing
moss (2 parts damp moss and 1 part of soil from the basin of old litchi tree) and wrapped with
polythene sheet. Both ends are tied with fine rope to make it air tight. When sufficient roots are
formed in about 2 months, the branch is cut below the soil or sphagnum moss and potted in a
nursery. July to October is the most appropriate time. About 6 months old air-layered plants
should be planted in permanent field in monsoon.
Planting:
Pits of 90 x 90 x 90 cm in dimension are dug at the spacing of 8 – 10 m apart in square
system. Pits are filled with topsoil mixed with about 40 kg decomposed compost, 2 kg
neem/karanj cake, 1 kg bone meal/single super phosphate and 200-300 g muriate of potash.
Incorporation of about 2 baskets of soil from the root zone of old lychee trees encourages the
mycorrhiza growth. Planting is done during June to July. At the time of planting a hole the size
of ball of earth is made in the centre of the pit at the marked point where the plant is fixed and
the soil is pressed to remove air. Watering is done immediately after planting for proper
establishment. Subsequently the plant is regularly irrigated till it is properly established.
Training and pruning:
Training of the plant in the initial stage is essential to provide the required framework.
Unwanted branches should be pruned to provide definite shape and to promote growth of the
trunk and crown of the tree. Three to four branches 60-75 cm from ground opposite to each other
are allowed to form the proper frame of the tree. Further, crowded and crisscross branches are removed to facilitate better growth.

For calla lilies, it provides grading guidelines and advises harvesting when the spathe has opened. For goldenrod, it notes varieties that remain upright and lists post-harvest treatments like sucrose that extend vase life to 13 days.
1. Plants are exposed to various stresses from both human activities and natural causes that can increase the production of reactive oxygen species (ROS) in plant tissues.
2. ROS are generated during normal plant metabolic processes and photosynthesis, but stress situations increase their toxic production.
3. Plants have developed complex antioxidant defense systems using enzymatic and non-enzymatic components like ascorbate, glutathione, phenolics and antioxidant enzymes to scavenge ROS and protect against oxidative damage.
This document discusses mutation breeding techniques for several flower crops. It begins by explaining naturally occurring and induced mutations. Various mutagens like radiation and chemicals are described. Examples of mutation breeding programs for petunia, chrysanthemum, tulip, carnation, rose and gladiolus are provided where mutants with new flower colors and morphologies were obtained. The conclusion states that mutation breeding is a beneficial tool for plant breeders to generate novel traits and expand genetic diversity in crops.
This document provides an introduction to floriculture, which is the cultivation and marketing of ornamental plants. It discusses the subdivisions of floriculture including commercial floriculture, arboriculture, and landscape gardening. Floriculture includes the production of cut flowers, loose flowers, cut greens, potted plants, and products for the perfume, pigment, and dry flower industries. The largest flower producer is the Netherlands, while India has potential to expand its small share of the global floriculture trade and areas of production include Tamil Nadu which is a leading producer of jasmine and other loose flowers.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Studies (VISTAS)
Pallavaram, Chennai, Tamil Nadu -600117
3. Introduction
• Litchi is a delicious juicy fruit
• It is a native fruit of warm subtropic zone of China - juice of excellent quality
• Tree is a medium large evergreen with more branches
• Fruits are produced in bunches
• Fruit is a one seeded nut, the pericarp is the skin, which has papillate projection
like strawberry
• Fleshy aril surrounding the seed is the edible portion, which separates easily
from seed and skin
• Litchi growing countries: China, Taiwan, Thailand, India, South Africa,
Australia and Madagascar
4. Composition and uses
• The fruits are a rich source of sugar (6-20%), protein (0.7%), fat (0.3%), minerals like
calcium (10mg) phosphorus (35mg) and vitamins like vitamin C (64mg), vitamin B1
(0.2mg), B2 (0.03 mg and B3 (0.1 mg) per 100g
• Fruits can be canned, made into squash, pickles, and wine or dried to form litchi nut
5. Origin and Distribution
• Origin of litchi is from southern China
• Spread other parts of the world was rather slow probably due to its soil, climatic
requirements and short life span of its seed.
• Litchi reached India through Myanmar and North East region during the 18th
Century.
6. Climatic and soil
• A warm subtropical climate is ideal for the growth and flowering of litchi
• Winter should be cool as well as dry and devoid of frost (minimum temperature
150C)
• During new flush, the temperature should be 28-30oC with high RH and heavy
rainfall
• During harvest the temperature should be around 24-28oC with bright sunlight and
high relative humidity
• An alluvial soil with good is the best for the growth of litchi
• Soil pH should be around 5.5
7. Haak Yip
Haak Yip
• Fruit is heart shaped each weighing 20-22g, skin is thin, soft and purplish red
• Flesh has an excellent aroma and is sweet in taste
• It separates easily from flesh
• It is the commercial cultivar of Thailand, Taiwan and China
8. Tai-so
Tai-so
• Fruits are egg shaped each weighing 22-26g, bright red skin changing to dull red at
maturity, flesh is sweet
• It is the commercial cultivar of Australia, Queensland and South Africa (Where
it is known as Mauritius)
9. Waichee and Rose secented
Waichee
• Fruit are small (16-18g) round with deep red skin
• It possesses soft flesh with abundant sweet juice
• It is cultivated in China and Australia
Rose secented
• Fruits are oblong conical with deep rose pink skin, pulp grayish white
• Aril has a delicate rosy flavor
• It is an important cultivar of India
Calcuttia and China: Upright tree growth habit - HDP
10. Muzaffarpur
Muzaffarpur
• One of the important litchi varieties mainly
grown in Bihar and its adjacent states.
• Fruits are oval or oblong- conical, deep
orange to pink with medium juicy sweet
pulp
• This variety bears profusely every year with
an average yield of 80-100 kg/tree
• It is grown in India
11. Bombai and China
Bombai
• Fruit is heart shaped, 15-20g in weight usually with
another under-developed fruit attached to stalk
• It is an important commercial cultivar of West Bengal
China
• Fruits are globose with a blend of red and marigold
orange
• Fruits are large, 25-27g having a sweet flesh with good
juice and pleasant aroma
• It is also one of the important cultivars of India
12. Propagation
• Commercial propagation of litchi is air layering
• Litchis can also be propagated by seeds, grafting or cuttings.
• Air layering done during spring and early summer season
• Stooling, apical grafting, approach grafting and shield budding are other methods of
propagation
• A windbreak should be established around the litchi orchard using eucaluptus,
casuarinas, jamun preferably before one year of establishment of litchi orchard
13. Planting
• Pits of 1 M3 are dug, allowed for a week, filled with 25kg FYM +2 kg of bone
meal and 300g of muriate of potash
• Spacing recommended is 10 M x 10 M
• If the soil is not fertile and the climate is comparatively dry, the spacing can be
reduced to 8 M x 8 M.
14. • Branches with narrow crotches should be removed
• Terminal buds in long branching cultivars should be removed to encourage
branching.
• However intensive removal of vegetative growth should be avoided as otherwise it
will delay the next season flowering.
Training and interculture
15. Plant protection
• Bark feeder (Indarbela tertronis) can be controlled by application of carbon
disulphide or formalin
• Leaf rollers can be controlled by Nuvan which has fumigant
• Red rust can be controlled by spraying lime sulphur -3 times during autumn and 3
times during spring
• Leaf galls, caused by eriophid mite is a common problem. This can be reduced by
pruning and spraying of conventional (or) new avermectin compounds viz.,
spinosyn, emanectin, spiromesifen etc.,
16. Flowering, harvest and yield
• Litchi trees vegetatively propagated come to flower at the age of 3 –5 years
• The new flush arising in spring end in inflorescence
• Fruits are harvested after full maturity and ripening on the tree itself
• Fruits are harvested as bunches, pre-cooled and then stored at 0oC to 1oC
17. Physiological disorders
• Litchi is affected by many physiological disorders
– Fruit cracking and splitting
– Flower and fruit drop
– Sunburn
– Irregular bearing
– Black tip, etc.
• Incidence and severity of these physiological disorders vary with locality, season,
cultivar and orchard management practices
18. Fruit cracking
• Most important disorder occurring in almost all the
important litchi growing countries of the world
causing losses as high as 5-70%
• Disorder is associated with hot dry weather, drought
and low calcium and boron concentrations.
• This can occur after irrigation or heavy rain, or just after an increase in relative humidity.
• Application of calcium @ 2 ml/l or application of 2, 4-D and NAA @ 20 ppm reduced
fruit cracking
19. Sunburn
• Occurrence of sunburn on fruits is a serious problem in India, South Africa,
Australia and Thailand
• Damage caused due to sunburn occurs up to 0.9-19.13% in different varieties
• Orchards having insufficient irrigation during fruit development stage favour
sunburn
• Light and sandy soils, only light irrigation with increased frequency (4-5 days
interval) is found to reduce the chances of sunburn
20. Flower and fruit drop
• Litchi trees suffer a heavy flower and fruit drop between flowering and fruit
maturity
• Only a small proportion of flower (2-18%) is carried up to maturity in different
cultivars
• Fruit drop may occur due to failure of fertilization, embryo abortion, nutrition
and hormonal imbalance and external factors like high temperature, low
humidity and strong westerly winds
• Timely treatment of plants for strong and healthy shoot production delays flowering
phase and increases the female flower ratio and finally the fruit-set
• Visits of honey-bees in orchards ensure better pollination and fertilization which
increases the fruit set and retention
21. Irregular bearing
• Irregular bearing is a serious problem in almost all litchi growing areas of the
country
• Bearing terminals of current year are more productive (70-95%)
• Late harvesting and severe pruning operations may lead to non bearing in that
particular year of operation
• Applying proper nutrition, irrigation and controlling insect-pest infestation can
significantly reduce the intensity of this malady
• Proper pruning and training operations (semicircular canopy) give rise to strong
and healthy flush that bear fruits in ensuing season
• Late pruning and training should be avoided
22. Retarded/ underdeveloped fruits
• Ensuring presence of pollinators in the bearing orchards during flowering to fruit
set stage and spraying plain water in early morning hours of the day during the
advanced stage of fruit growth and development have been found highly effective.
• An arrangement of sprinkler system of irrigation may be done to reducing this
disorder
