The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
4. Introduction
Papaya has 4 genera and 30 species.
It is naturally a dioecious plant, but gynodioecious cultivars have been developed in
papaya through breeding.
The leaves are palm like with long talks.
Flowers are borne in axillary position and solitary and fragrant with variety of sex
forms.
Fruit : fleshy berry.
Numerous round wrinkled black seeds.
8. Climate
It is a tropical fruit plant best grown in warm areas, plenty of
sunlight.
It needs adequate moisture and even distribution of rainfall
throughout the year and cannot withstand strong winds.
Temperature range of 21 C to 33 C is ideal for sturdy growth.
It grows well at altitude 1200m MSL.
Very much sensitive to frost.
9. Soil
Papaya grows best in light, well-drained soil rich
in organic matter.
Deep clayey soils that are prone to water-logging
should be avoided.
Papaya grows best at pH 6.0 to 6.5 but can tolerate
pH up to 5.8 to 7.0.
10. Varieties
Solo: It is a table purpose variety. The fruits are small with deep pink pulp and a
sweet taste. Excellent for kitchen garden.
Ranchi: It is a variety from Bihar and popular in south India. The fruits are
oblong with dark yellow pulp and sweet taste.
Pusa Delicious: It is a gynodioecious variety with 100% productive plants with
good fruit yield and quality having excellent taste and good flavor.
Pusa Majesty: This is also gynodioecious variety with high productivity and
better keeping quality of fruits. This is also one of the highest papain yielders.
Pusa Giant: This is a vigorous variety and is dioecious in nature. The fruits are
suitable for tooty-fruity and candies like petha.
11. Pusa Nanha- An extremely dwarf variety. It is suitable for kitchen gardens,
pot and roof cultivation. It is developed through mutation breeding.
Coorg Honey Dew: A selection from Honey Dew, it is a gynodioecious.
Pink Flesh Sweet: It is a selection with excellent-quality fruits. Fruits are
medium sized with pink flesh, The TSS is 12-14° Brix. It is a good dessert
variety.
CO-1 (1972): It is developed by sib mating Ranchi type over a period of eight
years. The plants are dwarf in stature and dioecious. There is no papain in the
fruit. It is a good table variety with good keeping quality.
CO-2 (1979): It is pureline selection from a local type. A dioecious type with
good Papain yield (4-6g per fruit).
12. CO-3 (1983): It is a hybrid derivative of the cross between CO-2 (female parent) and
Sunrise Solo (male parent). It is a gynodioecious variety.
CO-5 (1985): It is a selection from Washington type. It is a dioecious type suitable
exclusively for papain production giving 14.45g of dry papain per fruit.
CO-6 (1986): It is a selection from a giant papaya. The plants are dwarf. First harvest
can be had in 8 months of planting. It is suitable for papain (7.5 to 8.0g of dry
papain/fruit) and also for table purpose. Plants are dioecious.
CO-7 (1997): This variety (culture CP81) is gynodioecious in nature developed through
multiple crosses. The parents are Pusa Delicious, CO-3, CP.75 and Coorg Honey Dew.
Washington: It is a table purpose variety. Male and female plants are seperate.
17. FLORAL BIOLOGY
Dioecious papaya produces male and female flowers separately on
different plants while gynodioecious produces both male and female
flowers on the same plant.
The peak anthesis observed between 5-6 am. The receptivity of stigma was found
on day of anthesis and remains receptive for 6 days.
Three types of flowers ;
Female
Male
Hermophrodite
22. Propagation
Sexual Method -propagated by seeds
Seed germinates in 2 weeks.
Seedlings transplanted after 45-60 days .
Seed rate :
250-300g/h(Gynodioecious) and 400-500g/h (Dioecious) (20 seeds/g).
23. Asexual method:
Tissue culture technique using MS media
supplemented with NAA.
Shoot tip culture from seedling and laterals buds
from female plants of Coorg Honey Dew variety
was successful.
24. Land preparation
The land is ploughed and harrowed twice.
An elevated plot along the row is made by ploughing on barring
with two passes on each side. This will ensure proper irrigation
and drainage.
Organic fertilizer and manure should be spread and incorporated
in the soil during land preparation.
Land should be free from weeds before planting.
25. Planting density
1.8 m x 1.8 m = 3086 plants/ha for normally followed in most
places.
1.25 m x 1.25 m = 6400 plants/ha for Pusa Nanha is best for
HDP.
1.6 m x 1.6 m = 3906 plants/ha suitable for papain production.
A triangular 2 x 2 planting design can be adopted for non
mechanized
cultivation, and 2 x 2 x 4 in double rows for mechanized
cultivation.
26.
27.
28. Irrigation
After transplanting, make sure the plants get adequate water every 2-3
days until they are well established.
Water the papaya plants regularly especially when the climate is hot or
dry to prevent growth retardation, flower abortion and dropping of
young fruits.
We can use method of drip irrigation for efficient use of water.
Papaya requires 12 gals on water per day.
29. Manuring and fertiliser application
The nutrition for papaya differs from other fruit crops because of its quick growth,
continuous fruiting habit and higher yield.
NPK:: 250:250:500 g/plant, FYM 10 Kg/plant (UHS,Bagalkot).
Apply 20 g in each of Azospirillum and Phosphobacterium at planting and again after
six months of planting.
Deficiency of lime,zinc and boron has often been observed in papaya orchards.
Spraying of 0.5% Zinc sulphate and one spray of Borax (0.1%) may be done depending
upon the nutrient status of soil.
30. Weed control
Weeds can reduce by 25% production.
Deep hoeing is recommended during first year to check weed growth.
We avoid herbicides as much as possible since they kill microorganism in
the soil that helps enhance decomposition of organic wastes into fertilizer
and plant food.
Application of Fluchloralin or Alachlorin or Butachlorine (2kg/ha) as
preemergence 2 months after transplanting can control all weeds for 4
months.
31. Intercropping
Low-growing vegetables of short duration may be taken as inter-
crops.
An occasional thinning of fruits necessary to prevent
overcrowding .
Papaya also grows as filler or in plantations of other crops where
spacing is wide enough.
32. Removal of male plants
About 10% of the male plants are kept in the
orchards for good pollination where dioecious
varieties are cultivated.
33. Harvesting and yield
While picking fruits from the tree, care must be taken that they are not
scratched, and are free from blemishes, otherwise these are attacked by
fungus and start decaying during marketing.
On an average each plant of improved varieties bears 30-45 fruits,
weighing 40-75 kg in one fruiting season.
Average yield of 60-75 tons/ha may be expected in a season.
34.
35. Storage at :
10 oC-13 o C with Relative humidity 85-
90% for 1-3 weeks with proper handling.
Ethaphon treatment 1000 ppm increase ripening.
36. DISEASES
1. Stem rot / Foot rot:

aphanidermatu is mainly responsible for it.
Symptoms- Rotting of stem near collar region.
Control- Kavach/Rovral (2ml/litre) and Metalxyl/Mencozeb
(2g/litre) as and when required.
37.
38. 2. Powdery mildew:
Cause- Oidium caricae/ Laveilulla taurica
Symptoms-White mealy growth on leaves, petioles and
young shoots.
Control- Apply wetable sulphur ( 1g/litre ) during
September-January.
39.
40. 3. Anthracnose:
Cause - Colletotrichum gleoesporiodes
Symptoms- Dark brown depressed spots of chocolate colour.
Control- Apply Carbendazim (1g/litre) and Mencozeb (g/litre )
15 days before harvesting.
41.
42. INSECT- PESTS
1. White fly- Bemicia tabbaci
Symptoms of damage-Nymphs and adults suck the sap from under surface
of the leaves. Cause yellowing of leaves.
Control- Installation of yellow sticky traps. Spraying Imidachloprid 200SL
at 0.01% or triazophos 40EC at0.06% during heavy infestation.
43.
44. 2. Fruit flies- Bactrocera dorsalis
Symptoms of damage- Maggots puncture into semi-ripe fruits with
decayed spots. Oozing of fluid and brownish rotten patches on fruits.

traps. Spray Malathion 50 EC 2ml/litre.
45.
46. 3. Ash weevil- Myllocerus spp.
Symptom of damage- Grub feed on the roots. Wilting
of young sapling notching of leaf margin by adults.
Control- Dust Lindane 1.3 D at 25 kg/ha
to kill grubs. Spray Carbaryl 50 WP at 2g/litre.
47.
48. Mealy bugs-
Symptom of damage- Flatten oval insects(1-4 mm long).
They can transmit a viral disease known as leaf drop and
will cause a reduced yield.
Control- Spraying Malathion at the rate of 1.5 to 3.0 tbs. per
16 liter knapsack sprayer.
