In case, there was enough rain, the crops fertilized properly, when there wasn’t enough rain the crops just failed and most parts of the country were hit by famine. The advanced genetic and molecular techniques have resulted in new varieties of crop … It illustrates different aspects of greenhouse crop production and protection with special emphasis on greenhouse technologies, design and climate control, cropping systems, in particular those practices which help reduce pests and diseases incidence in crops, integrated pest management, the use of adapted cultivars, and the need for This soybean produces monounsaturated fatty acid oleic acid. Examples: (a) Transgenic soybean is developed. Several genes […] CROP PRODUCTION; ART, SCIENCE AND BUSINESS Crop Production is the art and science of the genetic improvement of crops to produce new varieties with increased productivity and quality. 3) If one crop is deep rooted, the other has shallow roots. ment of the sporophyte – note: lower plants often have this. 43.Write 4 differences between mixed cropping and intercropping. Food Resources: Cereals (Wheat, rice, maize, millets and sorghum) provide us carbohydrates; Pulses (Grams, pea and lentil) provide us proteins; Oil seeds (Soya bean, ground nut, sesame, and castor) provide us fats; Vegetables, spices and fruits provide us a range of minerals, nucleic acids and vitamins. 44.What is crop rotation ? Genetic engineering is used to produce crops with improved food quality traits. Chapter 15 CBSE Notes for Class 9 Download Free 1. 40. 46.What are the factors from which crops needs to be protected ? If you are a student of class 9 who is using NCERT Textbook to study Science, then you must come across Chapter 15 Improvement in Food Resources. It is a big change. Crop rotation confers various benefits to the soil. ADVERTISEMENTS: The below mentioned article provides a study note on transgenic plants. The crop canopy means the structure of leaves, stems and flowers found above ground. The high-yielding varieties of crops take less time for maturing than the traditional varieties of crops. This CBSE notes contains CBSE Key Notes, CBSE Revision Notes, Short Key Notes, images, diagrams of the complete Chapter 15 titled Improvement in Food Resources of Science taught in class 9. Write 4 advantages of mixed cropping. 4) One crop needs comparatively lesser water and nutrients than the other. IMPROVEMENT IN FOOD RESOURCES . After independence, the government planned to bring about improvement in this sector. 47.What is a pest ? 1:}Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons.. 2) One crop is tall growing and other is short growing. 42.Write 4 advantages of intercropping. Improvement in quality of food It is one aim of genetic engineering. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. However, things changed with time. (ii) Short duration reduces the cost of crop production, (iii)Uniform maturity makes the harvesting process easy and reduces loss during harvesting. Thus, component crops used in mixed cropping have different canopy. 41.What is intercropping ? The application of recombinant technique for horizontal transfer of gene in plant sys­tem has several limitations. It can improve human health. This has the following benefits: (i) Allow farmers to grow multiple rounds of crops in a year. Plant genome is exceedingly complex, involving a huge amount of DNA, which can accommodate sequences equivalent to 6-7 million genes in an average crop plant. 45.Write 4 advantages of crop rotation.
