Family Leguminosae (Fabaceae) is generally characterized by typical legume fruit and the ability to symbiotically fix nitrogen. Among the three subfamilies, Papilionoideae is the largest and possesses the lion’s share of economically important legumes including pulses and forages. Although monophyletic origin is generally considered, traces of polyphyly and paraphyly are evidenced in the subfamilies Mimosoideae and Caesalpinioideae by molecular phylogenetic studies. Development of robust cytogenetic stocks (aneuploids, polyploids, chromosomal aberrations, somaclonal variants, transformants, etc.) and novel functional genomic tools (mutants, molecular markers, DNA libraries, barcode sequences, etc.) have paved the way to legume classical and molecular breeding for high-yield, nutritional quality, biotic and abiotic stress tolerance, and enhancement of its bioactive natural antioxidants.
Synonyms:- Vinca rosea, Catharanthus, Madagascar,periwinkle.

Poisonous Hemlock
Conium maculatum L.
Description: A tall, usually much
- branched, imposing plant with
purple-spotted stems,
compound leaves, and small
compound umbels of white
Flowers.
Height: Two to ten feet.
Leaves: Pinnate compound.
Poisonous Hemlock:
Flowering: 2mm long, five petals,
compound umbel.
Habitat: Waste places, weedy areas, and
woodland borders.
Range: Throughout East, except Newfoundland &
Arctic, also in much of Western U.S.
All parts of this plant are poisonous,
containing the toxic alkaloid called coniine.
Toxin is a volatile oily compound.
Coniine was the first alkaloid synthesized
in the laboratory.
Piperidine structure: nitrogen in a
six-member ring.
Coniine killed Socrates!
Socrates drank a potent solution of poisonous hemlock 399 BC
Coniine causes paralysis of the diaphragm
and subsequent respiratory failure
No plant extract should be consumed by
unqualified practitioners!
Poisonous hemlock is a narcotic
herb that sedates and relieves pain.
The young leaves and fresh seeds
contain the highest alkaloid content.
Used by Greek and Arab physicians for a variety
of problems including arthritis.
It was not always effective …caused death... as
the difference btw. a therapeutic and a toxic
amount or measure can be very slight..
Poisonous Hemlock:
Overdoses can produce paralysis
and loss of speech being followed
by depression of the respiratory
function then death!
No plant extract should be consumed by
unqualified humans (practitioners)!
A current issue with poisonous hemlock is:
prevent livestock from consuming poisonous
hemlock while grazing (in large open rangelands)!

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

3. Fabaceae family
• Leguminosae or fabaceae also called the legume, pea or
bean family is the third largest family of the angiosperms
after Orchidaceae and Asteraceae and second to Poaceae in
terms of agricultural and economic importance.
• The family comprises of about 751 genera and 19,000
species.
• Recent molecular and morphological evidence supports the
fact that the Fabaceae is a single monophyletic family.
• The name 'Fabaceae' comes from the defunct genus Faba,
now included in Vicia. The term "faba" comes from Latin,
and appears to simply mean "bean". Leguminosae is an
older name still considered valid, and refers to the fruit of
these plants, which are called legumes.
3
4. • All pulses are leguminous but all legumes are not pulses.
• The species in this family are distributed worldwide but are
present in abundance in tropical and subtropical regions.
• The family is further divided into Papilionaceae ,
Ceasalpiniaceae and Mimosaceae.
• A few members of these sub-families :-
1. Papilionaceae – Pea; Cowpea; soybean; lentil; chickpea;
groundnut; black gram; green gram; kidney bean; lima
bean; pigeon pea; bengal gram; indian bean; cluster bean;
alfalfa; fenugreek; broad bean; indigo; flame of the forest;
sunhemp; sesbania; shisham; sweet pea; butterfly pea;
pongam etc.
2. Cesalpiniaceae – Bauhinia purpurea; gulmohar; tamarind;
peacock flower; sita ashoka; Parkinsonia etc.

46. Cowpea is a warm weather and drought resistant crop. It can
withstand heat better than most other legumes, but not cold or
frost. It is the most important pulse crop, particularly in
regions with low rainfall.
In Africa, about 98% of the crop is sown intermixed with
sorghum and millets, while it may also be grown in rotation
with maize or cotton. The crop is mostly grown by traditional
methods throughout the world. It matures within 60 – 70 days
depending upon the cultivar.
The mature seeds are an important pulse whereas the
immature tender pods are eaten fresh, frozen or canned. In
Africa, the young shoots and leaves are eaten like spinach. The
seeds may be used as concentrate for farm animals. The crop
is used as hay, pasture, soil cover and green manure. The
fodder is highly palatable to all types of livestock.
The dried seeds contain approximately 24.6% protein.
46
47. Cowpea Genetic Resources
• International Institute of Tropical Agriculture (IITA),
Ibadan, Nigeria houses the world’s largest collection
of cowpea with over 15000 unique accessions from 88
countries around the globe. It holds about 70%
landraces from Africa. Storage of the seeds is at
Svalbard (Global Seed Vault, a facility built in a
mountain deep inside the permafrost on a remote
island in the Arctic Circle, commonly called as
Doomsday Vault).
• Improved cowpea lines from IITA released for seed
multiplication in India are TVu 1977-01D (VITA-4),
TVu 1502, TV x 1843-01C
• An International Cowpea Disease Nursery (ICDN)
programme was started to identify stable resistance
against major diseases.
47
48. Cowpea Genetic Resources
• National Programme :
Breeding for grain type cowpeas was part of All India
Coordinated Pulses Improvement Project which has been
upgraded to “Directorate of Pulses Research” in 1984.
Now, it is Indian Institute of Pulses Research at Kanpur.
However, now it has been included in the ICAR
Coordinated Project on “Underutilized and
Underexplored Crops”. The programme of breeding
vegetable type varieties comes under All India Vegetable
Improvement Project which too has been upgraded to
“Project Directorate” level with effect from 1986. Now, it
is headquartered at Varanasi as Indian Institute of
Vegetable Research. The fodder cowpea programme is
coordinated by the project coordinating unit located at
Indian Grassland and Fodder Research Institute, Jhansi.

51. Botanical features
• Cowpea is an annual herbaceous
legume that can reach more than 80 cm
in height.
• Some varieties grow upright, while
others have procumbent stems, often
tinged with purple, that trail along
ground.
• Large dark green trifoliate leaves
provide a good ground cover that helps
conserve soil moisture.
51
52. • The flowers occur in alternate pairs
and range in colour from dull white to
yellow or lavender.
• They open in the early morning, close
by about mid day and then wilt and
die.
• Depending on the specific cultivar, the
pods can be curved, straight or even
coiled and the seeds may be solid
colours (red, black, brown, tan or
white) or speckled, spotted, marbled. 52
53. • The seeds vary in shape from
kidney-shaped to round, depending
on how tightly packed they are in
the pod.
• Two of the most well known
varieties are ‘Black-eyed’ (white
with a black spot where the seed
was attached to the pod) and
‘Crowder’ (so-called because the
seeds are crowded together in the
pods).
53
57. Vegetative characters
• Habit: low growing, vigorously
bushy or trailing annual herb
attaining a height of about 0.9-1.5
m.
• Roots: Branched strong deep tap
root system with nodules.
• Stem: Green, branched, spreading
cylindrical, hollow, hairless; the
main stem to about 1 cm thick;
trailing and twining stems
somewhat thinner. 57
58. • Leaves: The trifolilate leaves
with the terminal leaflet
symmetrical, and the remaining
pair more or less triangular to
egg-shaped, about 10 cm long
and 7 or 8 cm wide. Develop
alternately pinnately, compound,
with a swollen leaf base known
as pulvinus.
• Venation: Reticulate, unicostate.
Vegetative characters
58
59. Floral characters
• Flower: Bisexual and complete,
zygomorphic, hypogynous, white,
purple or violet in color.
• Inflorescence: Racemose
• Calyx: Sepals usually (5), two are large
and three small which make 2+3
arrangement of sepals, valvate
aestivation.
• Corolla: Petals usually 5, polypetalous
(butterfly like), vexillary.
59
67. Tits bits of cowpea
• DNP ; Vegetable meat
• International year of pulses – 2016
• Paraheliotrophy movement – leaf lamina of
cowpea grows or tilts slightly towards the sun.
• Photoinsensitive varieties – can be grown in
summer and rainy season both. Mostly bush types.
Eg. Arka Samrudhi.
• Photothermoinsensitive varieties – can be grown
throughout the year. Eg. Pusa Rituraj.
• Recommendation by ICAR - 15 ppm MH just
before flowering increases pod set by 30%.
• Cowpea is likely to herald “green revolution” in
Africa.
67
68. Tits bits of cowpea
• Maruca testulatis or Maruca vitrata – pod borer
most serious pest of cowpea.
• ANF – Protease inhibitor ; Oligosaccharides
• High monosaccharide : polysaccharide ratio is
needed in cowpea.
• Cowpea breeding – International Institute of
Tropical Agriculture, Ibadan, Nigeria.
• Strictly self pollinated crop because flower opens
between 7 – 9 a.m. but anther dehiscence is early
between 10 to 12:45 a.m. hence, the crop is
cleistogamous.
• Pedigree method of breeding is the most common
method used by cowpea breeders.

71. • Cowpea (Vigna unguiculata) originated in Africa and is
widely grown in Africa, Latin America, Southeast Asia
and in the southern United States.
• 90% of the total world acreage in Africa.
• In India, it is grown in central and peninsular regions,
Uttar Pradesh, Punjab, Haryana, Madhya Pradesh,
Gujarat and West Bengal.
• Cowpea is grown throughout the country for green pod
(as vegetable), grain and fodder.
• This crop can be grown in kharif and summer season in
North India, while in South India it is grown throughout
the year.
72. Uses:
• Cowpea is grown for its tender pods and dry seeds.
• The pods are rich in protein, vitamin-B and
minerals.
• It is also used as a fodder and green manure crop.
• Cowpea seed is a nutritious component in the
human diet, as well as a nutritious livestock feed.
• The seed is reported to contain 24% crude protein,
53% carbohydrates, and 2% fat (FAO, 2012).
• It has also been used successfully as ground cover
in orchards and inter cropped with cash crops such
as cotton.
73. Uses of cowpea
• Quick green manure
• IPM insectary crop – most susceptible to pod borer
hence, used as a trap crop to protect Indian bean.
• Companion crop
• Seed and feed options
• Low moisture need
• Cultivars for diverse niches
• Weed-smothering biomass- Drilled or broadcast
cowpea plantings quickly shade the soil to block out
weeds.
75. Climate
• Cowpea can grow in tropical and sub-tropical climate.
• It is a warm season crop and drought-hardy but can not
tolerate cold weather.
• Germination of cowpea is better between 12-15°C,
whereas proper growth and development takes place
between 27-350 C .
• Cowpea can grow both in spring and rainy season in
the plains. Some of its varieties can be grown as a
rainfed crop.
• A well distributed rainfall of 75 to 99 cm during its
growth period is the best for its cultivation.
76. Soil
• Cowpea grows well on a wide range of soils
including poor soils with low pH (soil pH is in the
range of 5.5 to 6.5.). However, saline and alkali soils
are not suitable.
• Sandy loam, silt loam and loamy soils are the best
suited for its cultivation. Well drained soils rich in
organic matter are very good for its cultivation.
77. Land preparation
• The field for cowpea is prepared in such a way that it
retains sufficient soil moisture required for seed
germination.
• Also, there should be proper aeration in soil for active
bacterial activities and plant root development.
• After giving pre-sowing irrigation, the field is
ploughed twice or thrice with a soil turning plough.
Then it is harrowed and planked to conserve soil
moisture.
• Farm yard manure is mixed in soil during the last
ploughing.
78. Sowing :
• In Gujarat condition, the cowpea grown in July-August
or for summer crop grown in February.
• Cowpea should not be planted until soil temperatures are
consistently above 65°F (17.5º C) and soil moisture is
adequate for germination and growth.
• Seeds will decay in cool, wet soils.
Spacing :
• Traditionally, in Gujarat it has been seeded in rows
spaced 45×15 cm or 45×30cm in the row.
• Seed should be planted 1 inch deep and good seed-soil
contact is important.
80. Seed Rate :
Seed rate for vegetable purpose-15kg/ha
Fodder Purpose -35-45 Kg /ha
Green Manuring Crop -35-40 Kg/ha
Emergence is epigeal (similar to common bean, and lupin) where
the cotyledons emerge from the ground during germination.
Fertilizer application:
• Recommendation by G.A.U for cowpea 10 to 15 t/hectare FYM
and N-20, P-40Kg/ha. Full dose of N at basal dose and P in two
split.
• Cowpea, like all legumes, forms a symbiotic relationship with a
specific soil bacterium (Rhizobium spp.).
• Rhizobium makes atmospheric nitrogen available to the plant by
a process called nitrogen fixation.
81. Irrigation:
Cowpeas are grown under both irrigated and
non-irrigated regions.
Cowpea is more drought resistant than
common bean. If irrigation is used, more
vegetative growth and some delay in maturity
may result.
The most critical moisture requiring period is
just prior to and during bloom.

112. Important Term
Pulse:
Derived from the latin word puls meaning thick soup or
portage.
Refers only to the dried seed.
Pulse are the edible seeds of plants in the legume family.
Some times called as “Grain Legumes”
Dried peas, edible beans, lentil and chickpea are most
common varieties of pulse.
Pulse do not include fresh beans or peas. Although they are
related to pulses because they are also edible seeds of podded
plants.
Like many leguminous crops rotation due to their ability to fix
nitrogen.
To support the awareness on this matter the United
Nations declared 2016 the UN International year of Pulses.
113. Legume
A fruit of simple dry fruit that develop from a simple
carpel and usually dehiscent on two sides.
The term legume refers to the plants whose fruit is
enclosed in pod.
Legume represent a vast family of plants including
more than 600 genera and more than 13000 species.
Fix nitrogen into soil which reduce need for
chemical fertilizer.
e.g. Alfa Alfa, Clover, Fresh peas, Lupins.
Common name is pod.
114. Forage:
Is a plant material (mainly plant leaves and stems) eaten
by grazing livestock.
Forage crop is used to define crops, annual or biennial,
which are grown to be utilized by grazing or harvesting
as a whole crop.
Fodder:
Is any agricultural foodstuff and specially to feed
domesticated livestock, such as cattle, goats, sheeps,
horses, chickens and pigs.
Fodder refers partially to food given to the animals
(including plants cuts and carried to them).
It includes hay, straw, silage, compressed and peelleted
feeds, oils and mixed rations, and sprouted grains and
legumes.
115. Lomentum
Is a type of indehiscent legume fruit that
breaks apart at constrictions occurring between
segments, so that each segments contains one
seed.
It is a type of schizocarp.
