3.2.2 Manures and Fertilizers Application in Nursery
Types of Manures
The excreta of animals including dung and urine, along with straw and other organic
materials are used as manures in crop production. The decomposed manure is called
Farm Yard Manure. The average composition of well decomposed Farm Yard Manure is
0.5 per cent nitrogen (N), 0.3 per cent Phosphorous (P2O5) and 0.5 per cent Potassium
(K2O). For the best performance of fruits and vegetables balanced nutrition of the nursery
plants are necessary. Balance nutrition can be achieved by supplying nutrients in both
organic and inorganic form.
� Organic manures
� Inorganic fertilizers or chemical fertilizers
� Biofertilizers
Manures
Manures are prepared by using plants and animal‟s debris.
It can be categorized as follows:
1. Manures from plant origin e.g. green manures
2. Manures from animal origin e.g. Poultry manure
3. Manures from plants and animal origin e.g. Compost, Farm Yard Manure.
4. Organic fertilizers e.g. Bone Meal, Fish Meal, Blood Meal.
Biofertilizers
1. Nitrogen supplying biofertilizers- Azotobacter, Rhyzobium, Acetobacter,
Azospyrillum.
2. Phosphate supplying biofertilizers – Phosphate solubalizing bacterias (PSB)
3. Microbial decomposers- Tricoderma viridae
Important Points regarding the Nutrition Management in Nursery Plants
� Selective and balanced nutrition should be given to the mother plants through soil or
irrigation. Excess nitrogen will reduce the root growth.
� In nursery different types of rooting media are used. It doesn‟t contain nutrients so we
have to provide nutrition according to plants need.
