3. USES
• Pigeonpea is the economical source of protein, carbohydrate, minerals and
vitamins such as B-complex particularly in the vegetarian diet. Along with
the cereals pigeonpea provide well balanced diet and can be comparable to
other dense protein sources like whey and soy.
• In India, red gram is mostly consumed in the form of ‘dal’ (decorticated
split cotyledons), after cooking in water, to the desirable degree of softness
and immature green seeds are used as vegetable.
• Nowadays pigeon pea is incorporated into food products like biscuits,
noodles, pasta, sausages as a novel ingredient for nutritional purposes,
owing to its high fibre and protein content, gluten-free status, low glycemic
index, antioxidants level.

4. CONT’D.
• The roots are anthelmintic, sedative, expectorant and vulnerary. The root bark
contains numerous flavones including cajaflavanone and cajanone, and triterpenes.
Some of them are antimicrobial agents.
• An infusion of the leaves is used as a treatment for pulmonary conditions such as
coughs and bronchitis. The leaf juice is taken internally in the treatment of
hemorrhages, coughs and diarrhea.
• An infusion of the flowers and leaves is diuretic and is used as a diabetes remedy.
• Due to its hardiness, ability to grow on residual soil moisture, and slow early
growth, this species is an ideal, non-competitive crop to plant with cereals. The
plant has an extensive root system and is often grown to bind soil as well as acts as
a good green manure crop.
• An essential oil can be collected by the steam distillation of the leaves and other
aerial organs. It contains a mixture of compounds including the terpenoid alpha –
copaene. The macerated leaves are used as a deodorant.

6. ORIGIN
• The cultivation of the pigeon pea dates back to at least 3,500
years and is assumed that eastern part of peninsular India is
the center of origin (Van der Maeson 1995).
• Atylosia cajanifolia is considered to be the closest wild
relative of Pigeonpea followed by A. lineata. (Pundir & Singh
1985).

• It is an erect shrub. The plant show considerable variations in
height, ranging from 1-4 meters. In most of the types branching
begins from the sixth to the tenth node, i.e. from 15-20
centimeters above the ground.
• Root system
• Root system of pigeon pea consists of a central tap root with
numerous lateral and secondary branches. The length of the
lateral roots differs with the variety; usually tall, upright
varieties produce longer and more deeply penetrating roots,
whereas spreading types produce shallower, more spreading
and deeper roots.
12/6/2019 8

9. • Leaves
• Leaves are trifoliately compound; central leaflet longer
than lateral ones. The leaflets are entire and densely silky
on the lower surface. Stipules are small; lamina hairy with
the under surface grayish due to dense hairs. The
intensity of the green color of the leaves differs with the
variety. The total length of the leaf, as also the size, shape
and texture of leaflets also differ with the varieties.

• Inflorescence
• The inflorescence is an axillary raceme often forming a terminal
panicle. The size of inflorescence varies in different types. The
flowers are distinctly papilionaceous. In the late maturing varieties,
the flowers are usually grouped together at the ends of the branches,
but in early maturing varieties, the flowers are produced at several
points along the branches. Usually flowers open at a time on the
same inflorescence, but the process of flowering continuous in each
plant almost up to the time of harvest. The flowers are self
pollinated, pollination takes place before the flowers open. Cross
fertilization may also occur to some extent.
12/6/2019 10

11. • Pods
• The fruit of pigeon pea is a pod. These vary in length,
width and nature of markings. The length varies from 5 to
10 centimeter, width from 0.6 to 0.9 centimeter. The pods
vary in color from green to dark brown. In some types,
they are broad and pendant with their tips pointing
downwards while in others they are quiet erect. The seed
with in the pod may vary in number, but there are usually
four to five in each pod in late maturing varieties and two
to three in early maturing varieties.

in size, shape and color. Seeds
are round or lens shaped, the
color of the seeds coat being
dirty white to silver white, light
brown to chestnut brown, dark
mottled brown and pinkish
black and the cotyledons yellow
colored.

16. CLIMATIC REQUIREMENT
• Pigeonpea is predominantly a crop of tropical areas mainly cultivated
in semi arid regions of India.
• Pigeonpea can be grown with a temperature ranging from 260C to
300C in the rainy season (June to October) and 170C to 220C in the post
rainy (November to March) season.
• Pigeonpea is very sensitive to low radiation at pod development,
therefore flowering during the monsoon and cloudy weather, leads to
poor pod formation.
12/6/2019 16

17. SOIL TYPE & FIELD PREPARATION
• It is successfully grown in black cotton soils, well drained with a pH
ranging from 7.0-8.5. Saline-alkaline and waterlogged soils are unfit as
they adversely affect nodulation.
• Pigeonpea responds well to properly tilled and well drained seedbed.
A deep ploughing with soil turning plough in fallow/waste lands, zero
tillage sowing under intensive cropping system and Broad Bed
Furrow/Ridge-furrow planting in low lying as well as intercropping
areas is recommended.
• Raised Bed method of planting by dibbling at 2 inches depth with Row
to Row distance 4 to 5 feet also 15 feet gap (2 pairs of Tur on bed)
under intercropping of soybean under transplanting (Dharwad
method/SPI), 5 X 3 and 3 X 1.5 feet spacing is recommended.
12/6/2019 17

18. SOWING TIME & METHOD
• Early Maturing varieties- First fortnight of June.
• Medium & Late Maturing Varieties-Second fortnight of June.
• Line sowing by seed drill or desi plough or by dibbling on the ridge
and beds, both are recommended as per the area.
• Late sown crop is more likely to be damaged by frost in northern parts
of the country.
In HP, Arhar is sown during the Last week of May-1st Week of June.
Earthing up is an important operation. First earthing up after 25-30
DAS and Second one after 50-60 DAS.
12/6/2019 18

19. CONT’D.
• Three systems of sowings are practiced for pigeon pea. The common
is flat sowing, the other methods are broadbed-furrow (BBF) for
extra-early group and ridge-and-furrow for the late maturity group.
• Bund cultivation of Pigeonpea in rice fallow areas have also been
adopted in CG, MP and some rice fallow areas. The latter two methods
are useful in fields with poor surface drainage and water logging.
• The raised beds or ridges also provide better aeration and nodulation
in comparison to the flat sown crop. At ICRISAT a broad bed and
furrow system is used for sowing extra-early genotypes, and ridges-
and-furrows are used for medium and late duration genotypes.
12/6/2019 19

20. SEED RATE & SPACING
• Early Maturing Var. - 20-25 kg/ha
• Spacing: 45-60 x 10-15 cm
• Medium/Late Maturing Var.- 15-20 kg/ha
• Spacing: 60-75 x 15-20 cm
In HP, for traditional varieties spacing of 50 x 15-20 cm while for
dwarf varieties it is 30-35 x 15-20 cm is recommended.
Seed rate recommended for HP is 15 kg ha-1.

12/6/2019 24

25. SEED TREATMENT
• Fungicide: Thiram (2gm) + Carbendazim (1gm) or Thiram @ 3 gm, or
• Trichoderma viride 57g /kg of seed
• Culture Rhizobium and PSB culture 7-10 g /kg seed.
12/6/2019 25

26. FERTILIZER APPLICATION
• This crop is a heavy feeder on the soil nutrients, hence, it should not
suffer from lack of nutrients. Being a leguminous crop it utilizes
atmospheric nitrogen through symbiotic nitrogen fixation with the
help of nodule bacteria to meet a major part of their nitrogen
requirement under normal conditions.
• A dose of 20-30:80-100: 40-60 kg NPK/ha is recommended.
• Soils deficient in zinc should get ZnSO4 @ 25 kg/ha at the time of
sowing.
12/6/2019 26

27. IRRIGATION & DRAINAGE
• Being a deep rooted crop, it can tolerate drought. But in case of
prolonged drought there is need of three irrigation
• 1st at branching stage (30 DAS)
• 2nd one in flowering stage (70 DAS), and
• 3rd at the time of pod formation stage (110 DAS).
• A pre-requisite for the success of Pigeonpea is proper drainage. Ridge
planting is effective in areas where sub-surface drainage is poor. This
provide enough aeration for the roots during the period of excess
rainfall.
12/6/2019 27

28. WEED MANAGEMENT
• The first 60 days is very critical and harmful for the Arhar crop.
• Two mechanical weeding's one at 20-25 days and another at 45-50
days after sowing but before flowering.
• The Pre-emergence application of Pendimethalin @ 0.75- 1 Kg a.i. ha-1
in 400-600 liter of water kills the germinating seedlings of weeds and
keep the field weed free for the first 50 days.
• If weed found from long time use then, Fluchloralin 50 % EC (Basalin)
1 kg a.i. ha-1 in 800-1000 liter water & well incorporated in the soil
before sowing or Alachlor 50 % EC (Lasso) 2-2.5 kg a.i. ha-1 in 400-500
liter of water as pre-emergence.
12/6/2019 28

29. RESEARCH DATA WRT WEED MANAGEMENT
• Pre-emergence application of Pendimethalin @1kg ha-1 followed by one
Hand Weeding at 45 DAS gave seed yield of 2.23 t ha-1 (Dhonde et al., 2009).
• Pre-emergence application of Pendimethalin @0.75 kg ha-1 followed by
application of Post emergence herbicide Paraquat dichloride @0.48 kg ha-1
at 42 DAS gave seed yield of 1.82 t ha-1 (Padmaja et al., 2013).
• Application of Imazethapyr @246 g ha-1 as post emergence gave seed yied of
2.56 t ha-1 (Bidlack et al., 2006)
• Application of pre-emergence Pendimethalin @1 kg ha-1 followed by
application of Imazethapyr as post emergence @0.10 kg ha-1 at 30-35 DAS
has been found effective towards weed control in pigeonpea (Kaur et al.,
2015).
12/6/2019 29

30. CONT’D
• Other Recommendations (Kaur et al., 2015) include:
• Clodinafop-proparagyl @50-60 g ha-1 as Post emergence
• Quizalofop @125 g ha-1 as post emergence
• Imazethapyr @ 100 g ha-1 as post emergence
• Pendimethalin @1 kg ha-1 as pre emergence followed by
Quizalofop @ 50 g ha-1 as post emergence.

31. CROPPING SYSTEM
• Important cropping systems followed are:
1. Maize–Pigeonpea (Rabi)
2. Pigeonpea-Urd-Wheat
3. Pigeonpea-Sugarcane
4. Mung + Pigeonpea-Wheat
5. Pigeonpea (early)-Potato-urdbean.
• Pigeonpea is commonly intercropped with a wide range of crops. In India, it was
estimated that 80 - 90 % of the Pigeonpea were intercropped:
1. With cereals (sorghum, maize, pearl millet, finger millet and rain-fed rice)
2. With legumes (groundnut, cowpea, mung bean, black gram, soybean)
3. With long-season annuals (caster, cotton, sugarcane, and cassava).
12/6/2019 31

32. HARVESTING & THRESHING
• With two third to three fourth pods at maturity judged by changing their color to
brown is the best harvesting time. The plants are usually cut with a sickle within 75-25
cm above the ground.
• Harvested plants should be left in the field for sun drying for 3-6 days depending on
season.
• Threshing is done either by beating the pods with stick or using Pullman thresher. The
proportion of seed to pods is generally 50-60%. The clean seeds should be sun dried
for 3-4 days to bring their moisture content at 9-10% to safely store in appropriate
bins.
• To avoid further development of bruchids and other storage pests, it is recommended
to fumigate the storage material before onset of monsoon and again after the monsoon
with ALP @ 1-2 tablets per ton. The small quantity of the produce can also be
protected by mixing inert material (soft stone, lime, ash, etc.) or by smearing
edible/non-edible vegetable oils or by mixing plant products like neem leaf powder at
the rate of 1-2% w/w basis.
12/6/2019 32

33. YIELD
• With use of improved technology of agronomic practices pigeon pea
may yield about 25-30 q/ha from irrigated condition and 15-20 q/ha
from un-irrigated condition. (depending upon maturity group of
variety and climate) and 50-60 q/ha of straw for fuel, as well.
