kpk and some parts of northern punjab

imp cash crop: raw material fro cigs manufacturing

17
Q

millets

A

can be grown on variety of soils even poor ones

many parts of Punjab (potwar region), many parts of KPK and Sindh

fodder for livestock and poultry, inferior grain for poor subsistence farmers

18
Q

maize

A

mainly in KPK and some parts of Punjab

corn flour, custard powder, etc

food grains for poor farmers

raw material for edible oil production

19
Q

pulses and grams

A

many parts of P&S and few districts of KPK

pulses enhance soil fertility by fixing nitrogen

source of plant protein, popular diet for poor

famouse varieties: Mung, Masar, Mash, Chana

20
Q

oilseeds

A

variety of soils even desert soils

northern and southern punjab, many parts of Sindh

only 32% production meets local needs, 68% imported

sunflower, soya bean, mustard, sesame = extract oil

linseed and castor = industrial

21
Q

livestock farming subsistence types

A

Nomadic

Transhumance

settled

22
Q

nomadic livestock

A

practiced by nomadic ppl of Balochistan and desert areas of P&S

move from place to place w animals in search of food and water

sheeps, goats, camels

sheep and goat = milk and meat, camels = means of transport and camel hide = making tents

grazing ground or water source = settle there for a few days

23
Q

transhumance livestock

A

seasonal migration

cattle, yak, dzu

animals kept high up in the pastures in summer and brought down to lower levels inn winters

animals often kept in sheds

western mountains: goat, sheep, cattle

meat, dairy products & wool

24
Q

settled livestock

A

villages on P&S

cows, buffalos, hens = eggs, milk to be consumed by fam

excess milk = processed = butter or ghee, cheese, yogurt

inputs derived from nature, traditional processes followed

wool or meat sold = buy more animals and necessities of life

25
Q

livestock commercial farming

A

practiced either on small scale by priv owners or large scale by govt owned or military farms

1990s involvement of major and multinational investors like nestle = farming boosted

bulk of livestock products supplied by small scale priv owners though they dont use all scientific methods

urban supplies of milk = buffalo herds in the cities

commercial dairy farms set up on vacant plots = lack appropriate drainage of water supplies = incompatible w modern hygiene city life

fodder brought by nearest crop growing area (lorries)

cattle dung collected and dried = plastered on wall = sold to market as manure or domestic fuel

australian designed dairy farms for Isl and Karachi (govt fairy farm for quetta)

scientific breeding methods (cross breeding) = increase fertility rates and better diets are in use in many such farms

early weaning diets = rearing buffalo and cow calves to save milk for human consumption

improve vetinary facilities = hired staff trained

26
Q

advantages of livestock farming

A

provide draught power in farming process (ploughing, threshing and harvesting), transporting materials, running persian wheel

source of food: cows & buffalos = meat and milk = ghee and butter, cow dung = cheap fuel, chicken = meat and eggs

provides raw materials to domestic industries (hides, skins, wool, animal hair and bones) for leather, woolen, textile industries and carpet and rug industries

contributes 10% GDP

27
Q

disadvantages of livestock farming

A

lack of grazing grounds

grazing unirrigated fields = soil erosion

high prices of animal feed, gap in prices of livestock products in rural and urban areas = limiting factor for further investment in rural areas

inefficient marketing of dairy products due to lack of supports from govt , less investment less profit

primitive breedin methods = poor quality breeds

poor facilities for storage and processing of livestock input + power shortage crisis

keeping animals i unhygienic conditions = spread of diseases

lack of veterinary care experts and poor control of outbreak of disease eg bird flu = srs problems for poultry industry

28
Q

cattle

A

most common

assisted by camels and mules to plough and transport fodder and workers

supply meat, milk, dung

traditionally ‘pride and prestige’

mainly reared areas:

P&S, KPK (sargodha, Multan, Gujarat, Tharparkar and Lasbela

29
Q

buffaloes

A

main source of milk and meat (produce 70% of total milk supply)

not imp as work animals

famous breeds for a good yield of milk: Nili Bar, Kundi and Ravi

reared areas:

prefer to remain in water hence mainly found in canal irrigated areas of P&S

30
Q

sheep and goats

A

sure footed ( capable of surviving in rugged terrain and harsh climatic conditions)

no large grazing ground needed (nibble at thin grass) = overgrazing

source of mutton (preferred over buffaloes in pak:

reared areas:

GB in northern mountains, KPK, rural and urban areas of Punjab and Thar, cholistan and thar deserts (kept by nomadic ppl of balochistan)

31
Q

poultry

A

growing population = rapidly growing industry

white meat > red meat

lesser investment required

desi variety of chicken > due to concerns abt breeding and feeding of modern farm chickens

32
Q

fruit farming

A

major fruit crops = apples, apricots and variety if dry fruits

growing regions: Swat, Hunza, Murree, Galiat region and in NM. valleys of n and nw balochistan (hilly areas w cool climatic conditions)

pomegranate, almod, grapes = balochistan (pishin and Mustung)

33
Q

bananas

A

temp required for growing = 27-29
sensitive to frost hence cant be grown in cld areas
high number of sunny days required
rainfall range 850-1050 m
soil should be well drained

mostly grown in Sindh and Hyderabad + neighboring districts as they grow well in warm and dry climate

34
Q

mangoes

A

S Punjab: Multan, Bahawalnagar
s and e Hyderabad
chaunsa exported to many countries

35
Q

dates

A

hot and dry regions of sindh
Oasis settlements of Miri, Sharak and Kech valley of Makran coast in Balochistan
most production in Balochistan goes to waste

36
Q

oranges + other citrus fruits

A

c and e Punjab
Kino in sarghoda and neighboring districts

37
Q

importance of fruit farming

A

source of nutrition (balanced diet)
raw material for food processing industry (juices, jellies, jam)
source of diversifying and increasing export earnings
peels/skins of some fruits =making imp items eg banana skin for fabric (recycling)

38
Q

physical factors affecting agricultural production

A

land and soil:
Flat land of Indus plain and valley areas facilitate large scale/cash crop farming
subsistence farming in mountainous and plateau regions
terrace farming on hill slopes in GB province
rich alluvial and loess soils
IRS spreads alluvium on Indus plains
lack of organic atter in Pak soils overcome by fertilizers

water and climate:
N Punjab eg potwar pleateu and mountainous valleys in KPK and GB = good amount of rainfall = barani farming
south: irrigation essential for large scale farming due to ineffective rainfall
heavy monsoons and glacial melting feed rivers that flow to Indus plains; reservoirs on these rivers needed
high summer temp suitable for Kharif; temps of winter = rabi

pests, insects , diseases
LCV & other harmful insects and pests may destroy crops
subsistence farmers vulnerable cuz they cant afford pesticides and insecticides
commercial farm: long term preventative and curative strategy adopted to deal w this

39
Q

human factors affecting agricultural production

A

irrigation facilities
semi arid - arid climate = need of irrigation for cash crop farming
reclamation of desert lands of P and S = increased agricultural area
modern irrigation = crops can be grown 2-3 times a year
extension of irrigation to soe parts of Balochistan eg in Lasbela plains cotton cultivation possible

A:
make up for the deficiency of rainfall
ensure better yield
source of reclamation of deserts
suitable for large scale farming
D:
subsistence farmers cant afford
if canal banks unlined = waterlogging and salinity
inefficient system of cleaning of canals

Fertilizers
add rich nutrients to soil lacking organic components
phosphate and nitrogenous brands popular
A:
better yield
speed up process of growth
suitable for cash crop farming
D:
poor farmers can’t afford
water pollution as they mix w irrigation water
eutrophication (stimulate growth of tiny plants like algae that may cover surface of water channel = marine life deprived of oxy and sun)

Mechanization:
tractors, harvesters and threshers instead of wooden plough and other traditional devices
tillers, reapers & transplanters for rice
large scale mechanization in 1960s as part of Ayub Khan’s green revolution
A:
speed up various processes of cultivation
machines can be attached to tractor
lesser number of workers required
suitable for large scale farming
D:
not suitable for subsistence farmers & fragmented holdings
expensive for poor farmers
diesel = air pollution
unemployment bec few ppl need (rural to urban migration)

HYV/GM
part of green revolution
need grew due to rapidly growing population
lesser yield fro desi variety
Nayyab = cotton
Mexipak = wheat
irripak = rice
A:
increased crop yield
drought resistant, pest and insect resistant
longer and stronger ste to withstand stormy winds
D:
expensive
need more irrigation and chemical fertilizers

40
Q

size of farm

A

uneven distribution of land holdings in Pak
small percentage of rich possess huge land holdings
poor farmers = fragmented holdings
research can’t be conducted on fragmented holdings and loans can’t be taken against them and use of machinery and canal irrigation not possible
land reforms of 1959, 72 and 79 for fair distribution
upper limit of land ownership fixed
fragmented holdings joined tgt under Land consolidation act
poor rate of success due to powerful social position of rich landed aristocrats many of who were always members if the parliament

41
Q

chemical fertilizers

A

rich nitrate ratio in soil and water channels = water pollution, eutrophication, domestic water supply carry pollutants = health problems for humans
crops use up soil nutrients = cattle manure high slurry = more polluting than domestic sewage

42
Q

insecticides and pesticides

A

weaken human immunity, more chance of infectious disease, carcinogenic chemicals, various pests and insects develop resistance against these chemicals = more powerful chemicals = health hazard for farmers and consumers (hand, respiratory system)
exposure of soil to wind/water = erosion, deforestation = erosion, after harvesting loss of topsoil = less fertility of soil, if land given rest = more erosion
irrigation = waterlogging and salinity if canal banks unlined ; unusual water loss, damage to fertile soil, additional cost of solving problem

42
Q

sustainable development w agriculture

A

practicing agriculture in such a way that there is more crop yield, healthier animals and minimum damage to environment so that future needs are secured
measures:
1. developing highly productive and eco friendly techniques
2. reclamation of deserts by irrigation schemes
3. conserving land by avoiding poor farming practices and overgrazing; soil management schemes thru afforestation, discourage deforestation on hill slopes, avoid over cropping as this exhausts soil nutrients
4. organic farming on large scale to encourage biological processes instead of chemical processes
5. training and educating farmers to adopt techniques aimed at conserving physical environment while enhancing crop yield; training them to to avail the residual moisture of soil in semi arid and barani areas
6. solar powered tubewells and tractors to minimize air pollution
7. setting up agricultural research institutes
8. more veterinary care institutes; research for cross breeding and early weaning for healthier varieties of livestock, incentives to be offered to attract investors for setting up modern dairy famers
