Title: Affecting useful soil microbes and remains of chemical residue become toxic to plants and adversely affecting health of the mango plant.


1
Role and deficiency symptoms of
Nitrogen in Mango
Introduction
Improved yield in mango require balance
application of nutrients in proper form. But
continuous and imbalanced use of inorganic
fertilizers affect the soil health as well yield
by
  • Affecting useful soil microbes and remains of
    chemical residue become toxic to plants and
    adversely affecting health of the mango plant.

2
Role and deficiency symptoms of
Nitrogen in Mango
  • Therefore, it is important to use chemical
    fertilizers judiciously to get higher yield
    without affecting soil health.
  • Integrated nutrient management is a good
    agricultural practices which improves yield in
    mango without affecting soil health.

3
Role and deficiency symptoms of
Nitrogen in Mango
  • Before adapting integrated nutrient management
    practice in mango, it is utmost important to have
    an idea about the role and deficiency symptoms of
    different elements on mango . Therefore in this
    RLO you will learn the role and deficiency
    symptoms of nitrogen on mango.

4
Role and deficiency symptoms of
Nitrogen in Mango
  • After completing this lesson, you will be able to
    answer
  • Learn the role of nitrogen in mango
  • Explain deficiency symptoms of nitrogen in mango
  • Describe symptoms of excess nitrogen in mango

5
Role and deficiency symptoms of
Nitrogen in Mango
  • Role
  • Nitrogen is one of the most important
    nutrients for the growth of mango .
  • It has a relevant role in the production and
    quality of the fruits.
  • Nitrogen effects are seen principally in the
    vegetative phase of growth

6
Role and deficiency symptoms of
Nitrogen in Mango
  • Role
  • Mango leaves with more than 1.2 N were
    associated with fruits that had greenish spots on
    reddish skin.
  • Nitrogen application induced flowering in the
    following years.

7
Role and deficiency symptoms of
Nitrogen in Mango
  • Role
  • Induced early flush and encouraged flowering.
  • N application increases yield and quality of
    fruits in mango.
  • Adequately nourished mango with N regularly
    develop shoots, and have viable panicles able to
    bear fruit.

8
Role and deficiency symptoms of
Nitrogen in Mango
Deficiency symptoms Nitrogen deficiency
may adversely affect yield. Lack of nitrogen
causes retarded development, less
vegetative growth and reduced production of
fruits. Due to nitrogen deficiency
relatively small fruit set associated with
leaves that matured without attaining normal size.
9
Role and deficiency symptoms of
Nitrogen in Mango
  • Deficiency symptoms
  • The deficiency symptoms first appeared near
    the base of current years growth, and progressed
    towards the tip, new leaves fails to attain
    normal size.
  • Leaf stalks tended to form narrow angles with
    the stem.

10
Role and deficiency symptoms of
Nitrogen in Mango
  • Deficiency symptoms
  • Fruit ripens prematurely and drop
    prematurely.
  • Nitrogen deficiency caused reduced leaf area
    and general yellowing
  • Excess of nitrogen causes excessive
    vegetative growth, difficulty at floral
    differentiation, loss of yield and fruit quality,
    and an increased susceptibility to disease.
