- 1. The table below shows the results of an experiment done on plants. Use the table to answer the questions below. Plant Soil Type Fertilizer Daily water Sunlight Height after 1 week Super-Gro Hyper-Plants 5L 1 Sand 5L Full 5 cm 2. Sand Fll 8 cm Sand Miracle Meal 5L Full 14 cm 3.1. Using the triangular and square methods of planting, determine the number of coconut planting materials needed to be planted in a 2-hectare field. The dwarf coconut seedlings will be planted at distance of 7m x 7m.16. The hydrangea is an unusual plant: its blooms change colour depending on the pH of the soil. If the pH is above 6, the flowers will be pink; below 5.5 they will be blue. A landscape gardener planned a garden for a client. The soil in the garden had a pH of 8.5. The gardener planted the hydrangea bush, fertilized it well, and watered it regularly with water collected in a rain barrel. The bush bloomed, but instead of the expected pink colour, the flowers were blue. a. Suggest an explanation for this unexpected observation b. What type of salt could be added to the soil to make the blooms pink?
- I grow two tomato plants from seed in separate pots next to each other on my porch. I use the same potting soil in each pot and water both at the same time each day. To one pot I add a small amount of Miracle-Gro, while I add no extra fertilizer to the other. At the end of 6 weeks, the Miracle-Gro plant has increased in weight by 210%, while the other plant has increased by only 65%. Fill in the following table. Is there a control treatment (and, if so, what is it)? Is there any accounting for individual variation? Is there repetition in the experiment? What, if any, confounding variables are not addressed in the experiment?1. In agriculture, briefly discuss three main phases of growth in relation to crop growth and development. 2. Plant requires large amount of mineral elements from external source to complete their life cycle. Discuss six issues that suggestively influence the uptake if mineral elements.Part 2: Assume that there is a nonzero average causal effect of soil fumigants on crop yield. In no more than 3 sentences, describe a setting, in terms of relationships between soil fumigants, eelworm cysts, and crop yield, where evaluating the mean difference in crop yield between treated/untreated fields with the same level of eelworm cysts would not produce a biased estimate of the causal effect of soil fumigants on crop yield. You do not need to provide numerical examples, just describe relationships among the fumigants, cysts, and yields.
