GROWTH AND DEVELOPMENT

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A farmer treated a population of corn plants with fertilizer. The farmer observed these corn plants, on average, were taller than another population of the same kind of corn plant that were not treated with fertilizer. The farmer’s observation supports which of the following conclusions?
A
Fertilizer cannot affect corn plant growth
B
Only fertilizer can make corn plants larger
C
Survival of corn plants is dependent on fertilizer
D
Fertilizer can affect corn plant growth
Explanation: 

Detailed explanation-1: -If plants are given nitrogen fertilizer, then they will grow taller.

Detailed explanation-2: -Generally, plants increase the growth by application of fertilizer treatments. Improvement of plant growth was significantly found by the application of both organic and inorganic source of mineral nutrition.

Detailed explanation-3: -Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. Nitrogen in particular is an essential nutrient for the growth of every organism on Earth.

Detailed explanation-4: -One possible hypothesis may be that there will be no effect on yield associated with N fertilization. This hypothesis, called the null hypothesis, is evaluated with an experiment to test crop yield response against a range of N rates in a field likely to produce a large response to the addition of N fertilizer.
