Transcript CULTURAL PRACTICES UNDER INM IN BANANA

Biofertilizers use in Banana
Introduction
Modern agriculture utilizes more and more synthetic
fertilizers. Excessive use directly or indirectly causes
soil ill health and declines crop productivity.
The importance of biofertilizer as a component of
integrated Nutrient Management (INM) is viewed as
sustainable crop production system, not only on yield
maximization but also for the agro-system stability. In
this RLO , types of biofertilizers, importance and
methods of their application are described.

Importance of Biofertilizer
•
Natural organic fertilizer.
•
Increases the quality of the soil.
•
Reduces toxicity of soil, water,
food, animals and even people.

Action of Biofertilizers
 Biofertilizers contains a wide range of naturally chelated
plant nutrients like
 Trace elements
 Carbohydrates
 Amino acids
 Growth promoting substances.
 Soil conditioner stimulating microbial activities resulting
in improved air-water relationships and soil fertility.

Vesicular Arbuscular Endomycorrhiza (VAM)

Mycorrhizae is the symbiotic association between
plant roots and soil fungus.

Vesicular Arbiscular Mycorrhizae (VAM) plays a
great role in inducing plant growth.

Makes resistance to environmental stresses.

Sucker Treatment
 Suspend 200 g N Biofertilizer and 200 g Phosphobacteria in
300-400 ml of water and mix thoroughly.
 Mix this paste with 10 kg seeds & dry in shade.
 Sow immediately.
 Dip the roots of seedlings in this suspension for 30-40 min
before transplanting.

Precautions

Store the biofertilizer packets in cool and dry place away from
direct sunlight and heat.

Use right combination of biofertilizers.

Rhizobium is crop specific, so use in specified crop.

Do not mix with chemicals.

Let us Sum Up

Use of chemical fertilizer leads to cause of soil
deterioration and water pollution.

In view of the disadvantages associated with the use of
chemical fertilizers, it is important to use alternative
sources, which are environment friendly.

Biofertilzers, most of which are nitrogen fixing
microorganisms, are considered to be suitable alternative
source of plant nutrition.

Farmers can adopt this technology to improve the land
resources and save natural environment.
