Which of the following management practices is most effective at reducing nitrogen leaching loss in sandy soils? Split application of nitrogen matching crop demand Irrigate heavily immediately after fertilizing Apply all nitrogen at planting as nitrate Use only phosphorus fertilizers 2. Which fruit group contributes most significantly to the global beverage and juice-processing industries? Citrus fruits and grapes Temperate drupes Aggregate fruits Tropical nuts 3. Which of the following is a major disadvantage of transplanting seedlings compared to direct seeding? Poorer crop uniformity Increased risk of root damage and transplant shock Longer time to harvest Higher seed requirement 4. Compared to open-field cultivation, growing of fruit tree nursery in tunnels typically reduces which environmental factor most significantly, thereby limiting photosynthesis? Light intensity and quality Soil moisture Wind speed Carbon dioxide concentration 5. _________________ is the most commonly used postharvest parameter as an indirect indicator of fruit sweetness Total Soluble Solids Fruit firmness Relative humidity Titratable acidity 6. Ethylene is primarily associated with ______________ Fruit ripening and senescence Root growth Water absorption Nitrogen fixation 7. A horticulturist aiming to reduce post-harvest water loss during storage should primarily ____________________ Minimize transpiration gradients between fruit tissues and surrounding air Adjust light quality Spay nutrient rich liquid Induce hormone mediated seed germination 8. Which fruit crop is globally regarded as a model system for studying climacteric fruit ripening and ethylene-mediated physiological changes? Tomato Strawberry Grape Citrus 9. What is the most immediate effect of reducing plant spacing (planting more densely) in an orchard? Increased light interception per plant Decreased competition for light No change in yield Increased competition among plants for light, water, and nutrients 10. Why is nitrogen (as nitrate) more mobile in soil than ammonium (NH₄⁺)? Nitrate is negatively charged and repelled by soil colloids; ammonium is positively charged and attracted Nitrate is a gas; ammonium is a solid Nitrate is larger in molecular size Ammonium evaporates quickly Loading … Question 1 of 10
