  • 1. Chapter 15 Improvement in Food Resources Part -1 Class 9 SA1
  • 2. What we are going to Learn • Why do we need to improve our food resources? • What are the various food sources of nutrients that we require to maintain a healthy lifestyle? • What is various Cropping Seasons? • What are the Strategies/practices used to improve these resources?
  • 3. What is the need for improving our food resources? • There is a need to introduce production efficiency of crops and livestock because-  rapid increase in population (4 times since Independence)  No major scope of increasing area of land under cultivation(only 25% increase in cultivable land area) How can It be done? – By employing sustainable practices! Q: What are Sustainable Practices? • Increase in food production and nutrient quality, without degrading our environment and disturbing the ecological balance is required in agriculture and animal husbandry.
  • 4. Major Advancements for Increase in Food Production in Our Country • The Following are the advancements in our country to increasing our food production. Green Revolution – Increase in Crop yield, variety and quality. White Revolution – Increase in Milk Production (Operation Flood) Blue Revolution – Increase in Fish production Yellow Revolution – Increase in oil seed production
  • 5. Types of Crops Grown in our Country (Crops that are sources for various important nutrients) • Cereals: wheat, rice, maize, millets and sorghum. Provide carbohydrates for energy requirements. • Pulses: pea, gram, black gram, green gram, pigeon pea and lentil. Provide proteins for Body Development • Oilseeds: soya bean, ground nut, sesame, castor, mustard, linseed and sun flower. Provide necessary fats. • Vegetables, spices and fruits provide vitamins and minerals for body functioning. • Fodder crops like berseem, oats or sudan grass are raised as food for the livestock(Cattle and Poutry)
  • 6. Cropping Seasons in India • Different crop require different climatic conditions, temperature and photoperiods for their growth and completion of life cycle. • Crops which grown in rainy season are called kharif crops. Kharif crops: paddy, soya bean, pigeon pea, cotton, green gram etc. • Crops which grown in winter season are called rabi crops. Rabi crops: wheat, gram, peas, mustard, linseed etc.
  • 7. Differences Between Kharif-Rabi Crops Kharif crop Rabi crop 1. Sown in the months of june- july. 1. Sown in the months of October- November. 2. Crops grow in hot and wet conditions 2. Crops grow in cold and dry conditions. 3. Crops are harvested during September- October. 3. Crops are harvested during marchapril
  • 8. Strategies or Practices we use to Improve our Existing Food Resources IMPROVING CROP YIELD • The practices involved in farming to improve our yield are divided into three stages. They are a) Appropriate Choice of seeds for planting. b) Improving Nurturing of the crop plants c) Protection of the growing and harvested crops from loss. • Hence the major activities for improving crop yields can be classified as • Crop variety improvement • Crop production improvement • Crop protection improvement
  • 9. Review Questions Why is Improvement in our food resources essential? Differentiate between Kharif and Rabi Crops, giving examples. What are the various sources for nutrients required in our diet?
  • 10. Do you know ? Operation Flood is a project of the  National Dairy Development Board (NDDB) which  was the world's biggest dairy development  program  which made India, a milk-sufficient nation,  the largest milk producer in the world, surpassing  the USA in 1998.
