Conduct a survey on crop fields. Interact with farmers on the crops grown on their farms and farm animals based on the following points —
Which crops do they grow through vegetative propagation?
Based on the survey, farmers grow crops through vegetative propagation using methods like cutting, grafting, layering, and tissue culture.
Which crops do they grow using seeds?
Farmers grow several crops using seeds, such as tomato, wheat, papaya, lady finger, brinjal, capsicum, orange, muskmelon, and apples.
Which seeds do they use — indigenous varieties or hybrid varieties? Why? How do they develop hybrid varieties in their fields?
Farmers use indigenous varieties of seeds because saving indigenous seeds is important, as emphasized by the Seed Village Programme (Beej Gram Yojana). The provided context does not detail how hybrid varieties are developed in fields.
List the indigenous breeds and hybrid breeds of the farm animals they are using in their farming practices and how are they different from each other?
While the context does not list specific indigenous or hybrid breeds of farm animals, it highlights beekeeping as a significant farm animal practice used in mixed farming techniques.
Discuss in class, and make a report on how asexual and sexual methods of reproduction are useful in agriculture.
Asexual methods of reproduction, such as cutting, grafting, layering, and tissue culture, are highly useful in agriculture as they produce genetically identical individuals. These methods enable farmers to efficiently propagate plants and cultivate desirable crops on a large scale, significantly improving agricultural practices.
Sexual methods, specifically pollination, are crucial for fruit production. For instance, in apple orchards, pollination by natural pollinators or through beekeeping ensures proper fruit setting and reduces fruit drop, thereby improving the overall yield.
Explanation
The answer is constructed strictly from the provided context. For (i) and (v), the context details vegetative propagation methods (cutting, grafting, layering, tissue culture) and their benefits (genetically identical individuals, efficient propagation, large-scale cultivation of desirable crops). For (ii), the context lists various fruits and vegetables (tomato, wheat, etc.) which are grown from seeds. For (iii), the context mentions the Seed Village Programme and the importance of saving indigenous seeds, but lacks info on hybrid development. For (iv), the context only mentions beekeeping as a farm animal practice, lacking specific breeds. For (v), the context also links sexual reproduction (pollination) to fruit setting and reduced fruit drop in apples.
