Introduction: |
|
Gram is believed to have originated somewhere in south west
Asia, probably in Afghanistan and/or Persia. According to De Candolle the gram is
mentioned in Sanskrit which indicates that it is cultivated in India from a longer period
than in any other country in the world.
In India, it is mainly grown in states of Bihar, Haryana, Madhya
Pradesh, Maharashtra, Punjab, Rajasthan and Uttar Pradesh, etc. It is used in may forms as
Dal, Chhole sweets and many attractive dishes and snacks are prepared from its flour. Its
leaves consist of mallic and citric acid which are very useful for stomach ailments and it
is best blood purifier. Nutritionally it is very rich as it contains about 17-21 per cent
protein, 62 per cent carbohydrate, good amount of fat; besides it is a rich source of Ca,
Fe, and vitamin C (in green stage) and vitamin B1. Its feed and straw are highly rich in
nutrients and are mostly used as productive ration.

Climate and Soil: |
|
Being a leguminous crop gram needs less rainfall and having a
deep rooted system it does very well under dry tracts which receive an annual rainfall of
60-100 cm. It prefers fairly cold weather but frost is deadly harmful, especially at
flowering and grain formation stages. Hail storm at maturity causes great damage to the
crop.
Gram is grown practically on a variety of soil types ranging from very
light to heavy ones. Maharashtra gram is grown on black cotton soils. The best type of
soil is clay loam with an efficient drainage and free from soluble salts preferably having
neutral pH.
|
Land preparation: |
|
Gram needs clodded and rough seed bed for good aeration in
root zone; thus a required seedbed may be obtained by one deep ploughing followed by two
harrowings. In diara lands one ploughing by desi plough brings about cloddy condition and
the crop can be sown.

Characteristic
features of important gram varieties:
|
|
Pusa 212: Released in 1982 having
semi-spreading and erect type of plants. The grains are medium bold and light brown in
colour. It may produce 18-20 q/ha.
Vikas : Early maturing resistant to wilt and yields
about 10 to 12 q/ha under rainfed conditions.
Vishwas : Development for eastern U.P., has bold seeds
and may yield 20-25 q/ha rainfed culture but is tolerant to wilt and of borers.
Chaffa: It has bushy, dwarf and early maturing (in 105
days) having medium bold, golden yellow and wrinkled seeds which may yield about 30-35
q/ha.
|
Sowing: |
a) Sowing time :
Second fortnight of October is found to be the best sowing time but
it may be delayed by first week of November for higher yields
b) Seed rate:
The seed rate is decided by seed size and weight but a seed rate of
75 to 100 kg/ha depending on these factors is used
c) Spacing:
A row spacing of 30 cm in desi types (Cicer areitinum) and 40-45 cm
in Kabuli types (Cicer kabulium) should be used.
d) Seed treatment:
For sowing the crop, seeds are treated with 0.25% thiriam

Application of
Manures and Fertilisers:
|
|
Being a leguminous crop gram does not respond to nitrogen
fertilization whereas the response of potash is very inconsistent but the phosphate plays
a very vital role in root development, nodulation and growth & yield of the crop.
However, Kabuli types need about 15-20 kg nitrogen/ha for a good initial boosting of the
growth. Therefore, it is recommended to apply about 15 kg.N/ha, 50-60 kg phosphorus and
the nutrient carriers must be basal placed at a depth of about 10-15 cm in the soil.
|
Interculture : |
|
a. Nipping: It is a special cultivation practice of
plucking the apical buds of the crop at about 30-40 days after sowing. Nipping stops the
apical growth and promotes the lateral branching, thus the plants become more vigorous and
produce more flowers and pods and yield per plant is increased.
b. Weeding : Gram responds well to hand weeding and
hoeing as it improves aeration. The best time for weeding and hoeing is between 25-30 days
after sowing and if the weeds are still present in the field, the second weeding should be
done about 60 days after sowing. Weeds may be controlled by herbicides also for which
Basalin at the rate of 1 kg a.i. per hectare should be used as preplant well incorporated
in the soil or Tribunil at the rate of 2.5 kg/ha may be sprayed as pre-emergence.
Fluchloralin @ 1 kg/ha or Oxidiazen @ 0.75 kg/ha may be sprayed as pre-emergence.
|
Irrigation: |
|
The crop is grown mostly under rainfed conditions where
irrigations are not possible but researchers have indicated that for higher yields light
irrigations are possible. There should be sufficient moisture in the soil while sowing the
crop. One light irrigation at flowering and one light irrigation at grain development
stage are required for good crop.
|
Plant protection
measures:
|
|
a. Control of insects/pests: Cutworm and pod borers are the
major pests of gram crop. The cutworms cut the tender stems, branches or damage the leaves
by cutting the top, edge or midribs, etc. Cutworms may be controlled by soil treatment
with 5% BHC dust or 3% Heptachlor at the rate of 25 kg and 35 kg/ha respectively. Aldrin
dust should be good substitute for these chemicals, if they are not available.
The pod borers use to bore the pods and eat the grains inside. They may
be controlled by spraying of 35 EC Endosulfan in the concentration of 2 ml/litre at 15
days interval and about two or three applications are required. Endosulfan also controls
aphids and cutworms if present in the field.
b. Control of diseases: The crop is prone to wilt, blight and
rust diseases which have practically no cure except using resistant varieties like BG-212,
Pusa 109 and C-235 for wilt prone areas and G-543 and C-235 for blight. Apart from using
resistant varieties seed treatment with Benlate and Thiram (1:1) at 2 g/kg seed; for seed
wilt, soil treatment with Brassicol and Captan at 10 kg/ha rate: and adoption of proper
crop rotation should be followed: Avrodhi, JG 315, ICCC 32, BG 244, GNG 146, CG 588 and BG
266 have resistance to both wilt and blight diseases.

Harvesting and
Yield:
|
|
a) Harvesting and threshing:
The crop matures within 130-140 days. After maturity the plants are
pulled out or when cut with a sickle leaves become reddish brown , dry up and start
shedding. The harvested plants are carted to the threshing-floor, dried for about a week
and threshed by trampling them under the feet of bullocks or by beating them with sticks.
b)Yield:
A good pure crop of gram gives about 15-20 quintals yield/ha in case of
desi varieties but the Kabuli varieties give about 25-30 quintals/ha yield. The yield in
case of mixed or intercrop depends upon the plant population of gram. |
