LET US SEE SOME FESTIVALS OF INDIA
Hey ! while reading book on festivals of India , I found some

Bhogali Bihu: (or Magh Bihu) is a harvest festival celebrated in Assam which marks the end of harvesting season in mid-January.
What type of festival these are called? (list on your worksheet )
What do you meant by harvest festival? Is there any relation between these
festivals and crops?(list on the worksheet)
Festival occurring prior or after harvesting of crops are called as
harvest festivalsYes ,These all festivals are related to
harvesting of crops
This all are related to agricultural crops
Which are the different harvest festivals celebrated in India ?
(list atleast three on the worksheet)
1. ---------------2. ---------------3. ---------------4. ---------------5. ---------------
1. Pongal2. Lohri3. Onam4. Bhogali Bihu5. Puthari/Huthari6. Sankranti
This all are related to agricultural crops
What are the 3 basic requirement for growth of crop?
for their Growth and Completion of their Life cycle
1) climatic conditions2) temperature3) Exposure to sunlight i.e. photoperiods
(list on your worksheet )
RABI CROPS
Grown in winter season
From November to April
E.g. Wheat, Gram, Peas, Mustard,
Linseed
KHARIF CROPS
Grown in rainy season
From month of June to October
E.g. Paddy, Soyabean, Maize, Cotton, Green
gram etc
CROPS
What is meant by kharif crop ?
(Write answer on worksheet )
What is meant by rabi crop ?
(Write answer on worksheet )

Let us see different types of kharif and
rabi crops
KHARIF CROPS
Maize SoyabeanPaddy
Cotton Urid Ground Nut
RABI CROPS
Gram Potato
Mustard Oat
Wheat
Coriander
Major seed producing state of India are shown along with rabi and kharif crops
Let us now see map of India
Observe very
carefully
(list any 5 on the worksheet )
Which are the kharif and rabi crop found in state of Maharashtra?
(list on the worksheet )
Which are the major seed producing states of India ? (any 5 )

Which are the kharif and rabi crop found in state of Maharashtra?
Kharif crops :- Paddy, Soyabean , groundnut, cottonrabi crops:- jowar
Which are the major seed producing states of India ? (any 5 )
What type of crop is grown in Orissa?
In Rajasthan which type of crops are mainly grown?
Paddy :- kharif crop
Wheat, mustard , gram :- rabi crops
Which type of crops are grown in Karnataka
Kharif crops
Why India is facing problem of shortage of food resources?
•It is because of overpopulation and•Lack of land for farming •Poor seed quality
So how we can meet the food demand?
No scope for increasing the area of land under cultivation
Population increasing
( list two things on worksheet )
The only way is……..
BY IMPROVEMENT IN FOOD RESOURCES
Nutrient management:
There are 16 nutrients which are essential for plantsNutrients are supplied by air, water and soil
Source Nutrients
Air Carbon, OxygenWater Hydrogen, OxygenSoil i. Macronutrients: ( in large amount )
Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulphur
ii. Micronutrients:( in small amount ) Iron, Manganese, Boron, Zinc, Copper, Molybdenum, Chlorine
What do you meant by micronutrient?
What do you meant by macronutrient?
( list on worksheet )
( list on worksheet )
Macronutrients :- required in large quantitiesMicronutrients :- required in small quantities
Deficiency of these nutrients in plants affects its growth and make it susceptible to diseases
How we can increase the yield of crop?
By using manure
Fertilisers
Mixed cropping
irrigation
(List 2 things in your worksheet)
1. ---------------2. ---------------3. ---------------4. ---------------5. ---------------
Now let us see some ways in which
nutrients is supplied to soil in order to
increase the crop yield
MANURE• Manure is prepared by the decomposition of
animal excreta and plant waste.• It increases the water holding capacity in
sandy soils. • Using biological waste material is also a way
of recycling farm waste
Compost and vermi-compost
Fertilizers
Way of Applying fertiliser in fields
Fertilizers supply nitrogen, phosphorus and potassium.
Fertilisers should be used wisely or else it creates harm to
environment
CROPPING PATTERNS
Growing two or more crops simultaneously on the same piece of land is known as ‘Mixed cropping’
• Mixed cropping
Ex.:- wheat + gram, or wheat + mustard, groundnut + sunflower.
Intercropping of Maize & Flax
Intercropping of Finger Millet & Sugar Cane
Growing two or more crops simultaneously on the same field in a definite pattern is known as ‘Inter-cropping’
INTER-CROPPING
Ex., soyabean + maize, or finger millet (bajra) + cowpea (lobia).
Let us see some weeds commonly seen during kharif
and rabi season
How these weeds are affecting crop yield ?
(list on worksheet )
Click here for answer
Amaranthus viridis (Chauli)
Trianthema (Saathi)Cyperinus rotundus (motha)
Wild sorghum or Jangli jowar
Some ‘Kharif’ season weeds:
Chenopodium album (Bathua)
Convolvulvus pluricaulis (Hirankhuri)
Wild oat (Jangali jaii)
Phalaris (Mandoosi)
Some ‘Rabi’ season weeds:
• Use of pesticides, which include herbicides, insecticides and fungicides.
• Mechanical removal.• Use of resistant varieties, and summer ploughing.
How we can control these Weeds?
• Preventive methods such as proper seed bed
preparation, timely sowing of crops, intercropping and crop rotation
(List atleast 3 ways on the worksheet)
1. ---------------2. ---------------3. ---------------4. ---------------5. ---------------
EVALUATION
