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)

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

Major seed producing state of India are shown along with rabi and kharif crops

Let us now see map of India

Observe very

carefully

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
