It involvess the cultivations of large hectares of land, huge investment of capital, the use of hired labour and the use of agro-chemicals 1b) * They assist in rural development by providing social amenities like, road,water supply,health centers. * They carry out research to improve or develop new crops varieties * The carry out research to improve or develop breeds of animals * Provision of financial support for agricultural extension project * Improvement of farmer awarness and agricultural knowledge 1c) - Construction of new feeder roads to open up the rural areas - Construction of wider ways to link up the river in areas - Construction of railways to connect rural area to the urban centers 1cii) - it prevent fragmentation of land since land aquired under the decree cannot be shared into bit - it has facilitated borrowing of capital for further investment in agriculture - it has reduce in the number and frequency of court case over land ownership - it made land acquisition relatively easier for new entrant into agriculture 3a)weathering can be defined as the breakdown of rock into tiny pieces to form soil . 3b) 1. planting cover crops:cover crops help to provide shade,prevent erosion and add more nutrients to the soil. 2. application of compost manure:it help to blind the sand particles together and also add more nutrients to the soil. 3. application of farmyard manure:this will add nutrients and also improve the structure of the soil. 4. mulching the soil:mulching sandy soil prevent water loss through evaporation and nutrient loss by water erosion. 3c) 1.it determines the level of fertility of the soil. 2.a good soil structure support aeration. 3.it also prevent erosion and wodertogging. 4.a good soil structure has a good water retaining capacity. 5.it also supports the growth of crops. 3d) 1.limestone-cac os 2.slakedlime-ca (OH)2 3.quicklime-cao 4.calcium bicabonate-ca(H CO3)2 5.gypsum-caso42 H20 5a) 1.aphids 2.cohoonstriner s 3.mealy bugs 5b) - 1.maize-(1)dent maize(2)flourco rn - 2.citrus-(1)swe et orange(2)sour orange - 3.yam-(1)drosco ren rotundata-white yam(2)dioscorea alata-water yam 5ci) * taungga system is the planting of both food crops and forest trees on the same piece of land 5ii) - 1.the prohibition of bush burning - 2.ban of indiscriminate culting of timbertrees - 3.encouraging people to plant trees 6ai. i. Mass selection: crop plant are selected or rejected on d basis of their own performance or merit. ii. Pure line selection: this type of selection in which only one crop plant with good characteristics 6aii). Dominant character: this is a trait or character that is expressed in an offspring when two individuals with contrasting characters or traits are crossed. Dominant genes on the other hand are genes which control dominant characters. For instance, in a very tall plant, there may be the gene for shortness but the gene has no influence on the gene for tallness. 6aiii. i. Proper timing of plant ii. Adoption of better cultivation methods iii. Use of manures and fertilizers iv. Control of pests of crops v. Use of resistant varieties vi. Use of good crop varieties. 6bi.Cassava mosaic disease i.Causual Organism virus. ii.3 Symptoms 1. Stunted growth. 2. Vein clearing 3. Distortion of leaves and stems iii.2 Preventive and control Measures 1. Uproot and burn infected plants 2. Farm sanitation 7ai) animal Improvement refers to the ways of developing and breeding only those animals that show the greatest merit under consideration such as good feed conversion,grow th rate,disease resistance,egg size etc. 7aii) Six Aims Of Animal Improvement i. To produce animals that can give high yield or products in form of meat,egg,milk,e tc. ii. To produce animals th
