Answer: (i) (a) India became the biggest producer and exporter of tea and rubber both the crops are grown for commercial purposes. (b) Indian agriculturists now raise as many crops as possible during the year with the aid of artificial irrigation, fertilizers, improved seeds, hybrid varieties and improved implements. (ii) Yield of Indian Agriculture is low as compared to world standards because: (a) Dependence on rainfall due to poor irrigation facilities. (b) Using of poor quality of seeds and lack of scientific approach. (iii) Two characteristics of plantation agriculture are: (a) Plantation crops are grown on large farms which are modem, scientific and self- contained units. (b) Only one crop is grown on a large scale. (iv) Consolidation provides a bigger sized compact area for cultivation to the individual farmers and the co-operative farming makes use of this bigger area for cultivation. Under this method several farmers, while retaining their ownership of land and managing it individually adopt the principle of cooperation for non-farm operations like marketing their produce, processing of agricultural products, obtaining inputs of agriculture like seeds, fertilizers and tools, etc. Question 2: What is ‘ratooning’? Give two advantages of ratooning. Answer: After harvesting, the lower part of the plant and the roots are left as they were in the field. This gives a new crop for the next year without fresh planting. This way the cane can be produced for three successive years. This is known as ‘ratooning’. Advantages: (i) The crop yields earlier. (ii) The cost of cultivation is reduced as no preparation is done for the fresh crops. Question 3: Briefly explain why sugarcane is increasingly grown in Maharashtra or Southern States Answer: Sugarcane is increasingly grown in Maharashtra or Southern States because of ideal geographical conditions. The States enjoys an extra advantage of marine influence. Ocean winds help the growth of sugarcane and increase the quantity of juice. Maharashtra has well-planned plantations and use modern scientific agricultural methods. The capital investment is tremendous due to the sugar lobby. Modem sugar factories are located close to the plantations. Irrigation and fertilizers are widely used to ensure a good crop of sugarcane. Question 4: Mention any two problems which the sugarcane growers are facing. Answer: The sugarcane growers face several problems, because of which they are unable to improve the yield and quality of sugarcane. (i) Sugarcane is a soil exhausting crop, so it needs enough quantity of manure while cultivating fresh crop. (ii) The farmers depend on canal irrigation for water requirements. The canals are often non-perennial and so the supply of water is uncertain. Question 5: What steps have been taken by the Government to solve the problems of sugarcane growers?

(ii) Mention the main tea producing areas of India. Answer: (i) Tea plant is not allowed to grow beyond a height of 2 to 3 metres. The leaves have to be hand picked as it needs regular pruning, After three years tea bush becomes ready, the skilled pluckers pluck the two leaves and bud pruning and plucking is done by hand so tea is considered a labour intensive crop. Assam and West Bengal are the two states in India where tea is widely grown. (ii) The main tea producing areas of India are on the hills bordering the Brahmaputra and Surma valleys in Assam. It is also grown in Darjeeling, Jalpaiguri and districts of West Bengal. Question 9: How has poverty and fragmentation of land became the problems of agricultural India? Answer: The small and marginal farmers are unable to buy good quality seeds and agricultural machineries which are very expensive. They follow a traditional method of farming so the yields are not high. Chemical fertilizers are costly and are often beyond the reach of the poor farmers. Inheritance laws in the country have laid to a continuous fragmentation of land over the years reducing the size of the land holdings. This results in large scale wastage of fertile land and labour and they become uneconomic for any useful agricultural activity. Question 10: Explain the following: (i) The propagation of rubber by the bud grafting method. (ii) The propagation of paddy by transplantation. Answer: (i) Budgrafting is done by the insertion of a strip of bark containing a bud from highyielding clones under the bark of a young seedling till they become united in 3-4 weeks. The old seedling stem is then sawn off above the grafted bark which then grows to form the new rubber plant. (ii) Transplantation involves the sowing of rice seeds in nurseries at the beginning of monsoons. When the plants are about 15-20 cm tall they are uprooted and replanted in parallel rows at regular intervals in flooded fields and left to grow till they mature.
