Answer 15

Symptoms include wilting, delayed flowering, and leaf curling.

Question 16

is needed for nitrogen fixation, enzyme activation, and the conversion of nitrate into usable forms.

Answer 16

molybdenum (Mo) in plants

Question 17

What are the symptoms of molybdenum deficiency in plants?

Answer 17

Symptoms include yellowing of older leaves, reduced fruit setting, and poor nitrogen utilization.

Question 18

regulates osmosis, ionic balance, and supports photosynthesis by facilitating water-splitting reactions.

Answer 18

CHLORINE (Cl)

Question 19

What are the symptoms of chlorine deficiency in plants?

Answer 19

Symptoms include wilting, leaf spotting, and restricted root growth.

Question 20

What are the effects of micronutrient deficiencies in plants?

Answer 20

Deficiencies cause poor growth, reduced photosynthesis, lower disease resistance, and decreased crop yield and quality.

Question 21

How do micronutrient deficiencies affect plant growth?

Answer 21

Plants may become stunted, have weak stems, and produce small leaves.

Question 22

How do micronutrient deficiencies impact photosynthesis?

Answer 22

Deficiencies can lead to yellowing (chlorosis) due to impaired chlorophyll production, reducing photosynthesis.

Question 23

What happens to a plant’s disease resistance with micronutrient deficiencies?

Answer 23

Weakened plants become more susceptible to infections and pests due to nutrient imbalances.

Question 24

How do micronutrient deficiencies affect crop yield and quality?

Answer 24

Deficiencies lead to poor fruit formation, delayed maturity, and poor overall crop quality.

Question 25

What are some natural sources of micronutrients for plants?

Answer 25

Organic matter decomposition and the weathering of soil minerals release essential trace elements.

Question 26

How are micronutrients applied to plants?

Answer 26

Micronutrient fertilizers (like zinc sulfate or boric acid) and foliar sprays ensure quick absorption, especially when root uptake is limited.

Question 27

How do soil amendments help with micronutrient application?

Answer 27

Adjusting soil pH enhances nutrient availability, and organic compost/biofertilizers improve soil health and micronutrient content.

Question 28

How does organic matter help with micronutrient availability?

Answer 28

Decomposing organic matter releases essential micronutrients into the soil, enhancing nutrient uptake.

Question 29

How does soil pH affect micronutrient availability?

Answer 29

Soil pH adjustments help increase the availability of certain micronutrients (e.g., acidic soils improve molybdenum uptake, while alkaline soils improve iron uptake).

Question 30

Why are micronutrients critical for plant productivity?

Answer 30

Micronutrients support vital processes like photosynthesis, enzyme activation, and disease resistance, ensuring healthy growth and optimal yields.

Question 31

What are the methods of applying micronutrients to plants?

Answer 31

Methods include applying fertilizers, foliar sprays, soil amendments, and managing pH for better nutrient uptake.

Question 32

How do micronutrients affect photosynthesis in plants?

Answer 32

Micronutrients like iron and manganese are crucial for chlorophyll production and photosynthesis efficiency.

Question 34

How do micronutrients affect a plant's disease resistance?

Answer 34

Micronutrients help strengthen plant cell walls and improve immune responses, increasing disease resistance.

Question 35

How does manganese assist in nitrogen metabolism?

Answer 35

Manganese is involved in nitrogen metabolism and helps in the conversion of nitrogen into usable forms.

Question 38

What impact does molybdenum deficiency have on plants?

Answer 38

Molybdenum deficiency can reduce fruit setting and hinder nitrogen utilization, leading to poor crop production.
