Explain any one method of crop production which ensures high yield.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><strong>Ans. <\/strong>To ensure high yield various cropping patterns can be very useful. The cropping patterns to be mentioned here are:<\/p>\n<p style=\"text-align: justify;\"><strong>(i)<\/strong>mixed cropping<\/p>\n<p style=\"text-align: justify;\"><strong>(ii)<\/strong>inter cropping<\/p>\n<p style=\"text-align: justify;\"><strong>(iii)<\/strong>crop rotation<\/p>\n<p style=\"text-align: justify;\"><strong>Mixed cropping<\/strong> is growing two or more crops simultaneously on the same piece of land, for example, wheat + gram, or wheat +mustard, or groundnut + sunflower. This reduces risk and gives some insurance against failure of one of the crops.<\/p>\n<p style=\"text-align: justify;\"><img decoding=\"async\" id=\"Picture 1\" style=\"height: 155px; width: 235px;\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/ncert\/09\/science\/ch15\/image003.png\" \/><\/p>\n<p style=\"text-align: justify;\"><strong>Inter-cropping<\/strong> is growing two or more crops simultaneously on the same field in a definite pattern (as shown below). The crops are selected such that their nutrient requirements are different. This ensures maximum utilisation of the nutrients supplied, and also prevents pests and diseases from spreading to all the plants belonging to one crop in a field for example, soyabean + maize, or finger millet (<em>bajra<\/em>) + cowpea (<em>lobia<\/em>).<\/p>\n<p style=\"text-align: justify;\"><strong>Crop rotation<\/strong> is growing of different crops on a piece of land in a pre-planned succession. Depending upon the duration, crop rotation is done for different crop combinations. The availability of moisture and irrigation facilities decide the choice of the crop to be cultivated after one harvest. If crop rotation is done properly then two or three crops can be grown in a year with good harvests.<\/p>\n<hr \/>\n<p style=\"text-align: center;\">NCERT Solutions for Class 9 Science Improvement in Food Resources part 2<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"2_Why_are_manure_and_fertilizers_used_in_fields\"><\/span><strong>2. Why are manure and fertilizers used in fields?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><strong>Ans. <\/strong>Manure helps in enriching soil with nutrients and organic matter and increasing soil fertility. The bulk of organic matter in manure helps in improving the soil structure.<\/p>\n<p style=\"text-align: justify;\">Fertilizers are used to ensure good vegetative growth (leaves, branches and flowers), giving rise to healthy plants by providing specific nutrients like nitrogen, phosphorus and potassium.<\/p>\n<hr \/>\n<p style=\"text-align: center;\">NCERT Solutions for Class 9 Science Improvement in Food Resources part 2<\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"3_What_are_the_advantages_of_inter-cropping_and_crop_rotation\"><\/span><strong>3.

How do good animal husbandry practices benefit farmers?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><strong>Ans. <\/strong>Animal husbandry is the scientific management of animal livestock. It includes various aspects such as feeding, breeding and disease control.<\/p>\n<p style=\"text-align: justify;\">As the population increases and as living standards increase, the demand for milk, eggs and meat is also going up. Also, the growing awareness of the need for proper treatment of livestock has brought in new limitations in livestock farming. Thus, livestock production also needs to be improved. This improvement can be brought about by good animal husbandry practices like providing good food and preventing diseases in the cattles that will benefit farmers to obtain better quality and quantity products.<\/p>\n<hr \/>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"7_What_are_the_benefits_of_cattle_farming\"><\/span><strong>7.
