Di-ammonium phosphate (DAP) DD. 14-35-14 complex fertilizer Next Slide 12 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 11. Most of the Indian soils are rich in potassium. So, there is no need to apply potassium to groundnut crop. AA. I agree with this statement BB. I do not agree CC. I need more information to decide on potassium application DD. I am not sure Next Slide 13 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 12. What is the source for calcium application to groundnut crop? AA. Sulfur BB. Ammonium Sulfate CC. Gypsum DD. Acid lime Next Slide 14 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 13. At what stage of groundnut crop calcium is applied? AA. At final ploughing BB. At sowing CC. At peak flowering DD. At any stage of the crop Next Slide 15 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 14. What is the recommended rate of gypsum application to groundnut crop? AA. 300 kg/ha BB. 100 kg/ha CC. 50 kg/ha DD. 30 kg/ha Next Slide 16 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 15. Sulfur application to groundnut crop improves AA. protein content. BB. pod development. CC. kernel development. DD. oil content. Next Slide 17 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 16. Why micronutrient application to groundnut has become important recently? AA. Growing of improved varieties. BB. Because of irrigation. CC. Continued use of common fertilizers. DD. Intercropping with other crops. Next Slide 18 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 17. The most frequently deficient micronutrient in groundnut growing areas. AA. Copper BB. Molybdenum CC. Manganese DD. Zinc Next Slide 19 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 18. The micronutrient which helps in good kernel development in groundnut. AA. Boron BB. Molybdenum CC. Iron DD. Zinc Next Slide 20 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 19. What should be the basis for deciding the amount of manures and fertilizers to groundnut? AA. Plant uptake BB. Variety grown CC. Amount of rainfall DD. Soil test report Next Slide 21 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition 20. What happens with improper incorporation of partially decomposed organic manures to groundnut crop? AA. Unavailability of micronutrients BB. Increases soil pH CC. Utilizes more soil moisture DD. Results in problems of germination and seedling diseases Next Slide 22 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Thank you for completing this exercise. Now you may review this Module or select next Module i.e. Module VI from Course contents. Slide 23 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is not correct. The correct answer is: Application of manures and fertilizers is important in groundnut because its energy requirements are high. Slide 24 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is correct. Application of manures and fertilizers is important in groundnut because its energy requirements are high. Slide 25 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your are right. The demand for nitrogen is high in the early stages of groundnut growth when nitrogen fixation has not yet started. So, a starter dose of nitrogen application is important for getting higher groundnut yields. Slide 26 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is not correct. The correct answer is: It is a false statement. The demand for nitrogen is high in the early stages of groundnut growth when nitrogen fixation has not yet started. So, a starter dose of nitrogen application is important for getting higher groundnut yields. Slide 27 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your are right. Calcium demand is high at the time of pod filling stage, but the calcium in the plant body is not available for the developing pods. Slide 28 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is not correct. The correct answer is: Calcium demand is high at the time of pod filling stage, but the calcium in the plant body is not available for the developing pods. Slide 29 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your are right. Sufficient availability of nitrogen to groundnut crop is reflected in dark green color of stems and leaves, and vigorous growth. Slide 30 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is not correct. The correct answer is: Sufficient availability of nitrogen to groundnut crop is reflected in dark green color of stems and leaves, and vigorous growth. Slide 31 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your are right. Excess of nitrogen results in too much of vegetative growth at the expense of groundnut pod production. Slide 32 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your answer is not correct. Excessive nitrogen application reduces nitrogen fixation and delays flowering. The correct answer is: Excess of nitrogen results in too much of vegetative growth at the expense of groundnut pod production. Slide 33 Virtual Academy for the Semi Arid Tropics Course on Groundnut Production Practices Module V Groundnut Nutrition Your are right. Ammonium sulfate also contains sulfur (16%), an important nutrient for groundnut crop. Slide 34 Virtual Academy for the Semi Arid Tropics Course on
