Write true or false and correct the statement if it is False:- Attempt any 8 questions. **(8X1-8.0)** 1. Crop rotation increases the erosion of soil from water and wind. 2. The word tillage is derived from the Anglo-Saxon word "tilian and teolian", which means to plough and prepare the soil for seed to sow, to cultivate and to raise crops. 3. The removal of entire plants or economics parts after maturity from the field is known as threshing. 4. The term Ideotype was first proposed by James D. Watson in 1953 working on soybean. 5. Grey revolution is related to petroleum products pink revolution is related to meat poultry pigarry.onion 6. The model which perform best when the plants are space-planted are called market Ideotype. 7. There are several objectives of tillage of which the most important are suitable seedbed preparation, weed control and soil and water conservation. 8. Crop rotation improves the physical and chemical condition of soil and thus improves overall fertility of the soil. 9. Aqua seed drill which drills both water and seed simultaneously is highly useful for sowing crops in wet soil in the event of delay in the receipt of rain without losing season. 10. Growth is an irreversible change in qualitative change in the plant body. 11. Formation of tied ridges reduces the response to rainfall and fertilizer, the soil supply of plant available N, the positive effect of inter-cropping on total grain yield and the harvest index. 12. Minimum tillage is aimed at increasing tillage to optimum necessary for ensuring a good seedbed, rapid germination, a satisfactory stand and favourable growing conditions. ## 4.
