Question: A farmer comes to see you and ask for your help. His corn has low yield.
1. What kind of information you would need to know in order to help the farmer? (5 points)
Water
When corns were got deficient water. Thus, corns were not substrate for photosynthesis rate and stress. Corns produced less carbohydrates and starch that affect to yield. Root phenotype is long and short .long root is deep in soil for absorption of underground water. Short root is spread wide root at absorption of top soil for water and nutrients. When corns were got a lot of water or flood. Sometimes root of corns were not oxygen. Corn is low photosynthesis rate.
Light
Corns are low photosynthesis rate at low intensity light because photosynthetic pigments are

Stamatas are closing because the protection out carbon dioxide refers to photosynthesis rate and high transpiration. Rain season is cloud and dark sky. Corns are low photosynthesis rate because time of light is attached leaves less.
Soil texture Clay soil is pack particle. So roots are short and low absorption is nutrient and water. Sandy soil is short root is spread wide root at absorption of top soil for water and nutrients.
Soil pH Soil pH affects to absorb for nutrients such as nitrogen is high absorption at pH levels of 6-8.5.but soil pH range of 6-7 is low absorption. There are iron, manganese, zinc. The optimal of soil pH is 7.0. Microbial activity and fertilizes efficacy are related to pH level.
Temperature
High temperature is high transpiration. And then corns are low photosynthesis rate because stomata are closed. The shape of leaves is roll. The enzyme of photosynthetic are degraded from non-optimal temperature. Low temperature is low transpiration and photosynthetic are degraded.
Fertilizer
The method use fertilizer for corns. The high fertilizer is toxin of plants. Disease and

Based on lab test results, the plants had low tissue P content and it was a dry year. What are typical morphological and anatomical characteristics that you would see in the crop? (5 points)

Morphological characteristics Leaf of corns showed deep green with reddish purple tips and leaf margins. The shape of deep green is V-shape from top to base and symptom displayed on old leaf. Corn plant showed smaller than wild type

Anatomical characteristics
Roots showed decreased aerenchyma and diameter of the root , long root hair and Epidermal cells of the root changed to thickened up endodermal and pericycle cells became shorter and thick walled.
Vascular area reduced with volume and size of xylem vessels
Leaf decreased number and smaller sized stomata in leaves and stem

In dry.
Corn showed stunt and the leaves displayed to change shape leaves and trichromes such as curl or roll towards the midrib. Root hair length is long and root is long at deep soil.
And closed stomata whereas air is dry its connect to carbon dioxide and refer to accumulate food (photosynthesis).

3. How would you provide short and long-term solutions to help the farmer using the knowledge you had learnt in the class? (10 points).
