Fermented Plant Juice (FPJ)

FPJ is a fermented extract of a plant’s sap and chlorophyll's. It is a rich enzyme solution full of microorganisms such as lactic acid bacteria and yeast that invigorates plants and animals. FPJ is used for crop treatments.

Materials/ ingredients needed:

Mugwart / Water amaranth / Bamboo shoot etc.

Jaggery / Brown sugar

Clay jar / glass jar

Porous paper (paper towel)

Rubber band / thread


Plants that are strong against cold and can grow well in spring. This is in order to pass down the characteristic of plants that can endure extreme climatic changes.

Plants that grow fast and are vigorous. Fast developing plants have growth hormones that are very active. This characteristic can improve any plant weaknesses and the recovery of certain health problems of the plants.

Fast-growing and vigorous plants. For example, Bamboo shoots and lateral buds of all kinds of plants have abundant growth hormone and vitality.

Thinned-out fruits have a lot of gibberellins which makes plants healthy with thicker foliage and enhances the thickness of fruit.


Avoid days when there is excessive sunshine or rainfall. Excessive sunshine may evaporate nutrients. Too much rainfall may wash away important nutrients and microorganisms. When there is rain, collect only after two days.

Collect the ingredients just before sunrise. Plants have perfect moisture level during this time.


Shake off dirt from the Plants but do not wash in water. Washing will remove useful microorganisms. If the ingredients are too big, cut them to adequate sizes, about 3 to 5 cm. This increases contact surface area and promotes osmotic pressure. (Do not mix different kinds of ingredients in one container. Use separate container for each ingredient.)

Measure the weight of the ingredient and the weight of brown sugar. Brown sugar should be between half of the weight of the ingredient. You should add or subtract sugar according to plant’s moisture level.

Put the ingredients and brown sugar in a large wide container and mix them with your hands. Cover with porous paper and leave for 1 to 2 hours.

Put the mixture into the clay pot. It should fill up ¾ of the jar. It is important that the jar is not too full or under full. The empty space is not empty. It is filled with air, for optimum fermentation to occur.

Put weight (Stone) on the mixture to control the amount of air in it.

Put on the cover and tie the jar. A cover is needed to prevent insects from getting into the mixture. Paper is ideal because it lets the air in and out.

Remove the weight after 1 or 2 days. After the air has escaped, put back the cover again.

Put the jar in a cool and shaded place. Do not open, move or stir the ingredients during the process of fermentation.


Germination to early vegetative growth: Mugwort (Artemisia vulgaris, Mosapatri in Telugu), and bamboo shoot FPJs are suitable at this stage to help crops become resistant against cold and grow fast and strong. FPJs should be used at lower concentration during this stage, preferably at a dilution of 1:1000.

Vegetative growth: Arrowroot and Bamboo shoot FPJs, as well as Reeds (water or marsh plants with a firm stem), help crops obtain their needed nitrogen to increase in volume. At this stage, FPJs can be used at a general dilution of 1:800 to 1:1000.

Presence of pests: FPJ can be used to keep pests away from fruits. Amixture of FPJ and rice bran can be sprinkled on the area around fruit trees to lure pests to the ground, thus preventing them from going to the fruits.


During excessive vegetative growth or overgrowth due to prolonged rains or cloudy weather.

FPJ made from the crop itself should not be used as this will promote further growth.

During acidic or nitrogen-excessive crop conditions, which create a pest-attractive environment.

Conditions of too much moisture or of bad ventilation, which promotes fungal growth.


FPJs are normally used at a dilution rate of 1: 800 to 1000 in water. When FPJ is used with other NF inputs, more water should be added to the solution. FPJ from the same crops to get better results:

Tomato, (Chilli, brinjal, etc,). lateral buds of stems and leaves for tomato plants.

Squash and sweet potato- vines for same crops.

Pinched shoots of plants (not contaminated by chemicals).


Polyethylene or glass products or clay jar may be used as a container. When using glass bottles, brown glass containers must be preferred.

Store in a cool place. Select a shaded area where there is no direct sunlight and where the temperature does not fluctuate. Direct sunlight should be avoided.

The optimum temperature range is 1 to15ºC for storage (Use a Refrigerator if available) if you want to keep for one year. Otherwise one can use within 30 days store at room temperature.


It is not recommendable to use molasses as it contains too much moisture to raise the osmotic pressure as high as brown sugar does for good fermentation.

Sometimes small bubbles or fungi will be present in the Jar. They result from lacking brown sugar or from an unbalanced volume between the empty space and the ingredient. In this case, add a little brown sugar, stir and preserve after filtering.

Avoid excessive sunshine (heat). Avoid sunlight for picking plants. If the hot weather continues, but FPJ production must continue, then water the plant one day before picking the plants / leaves before sunrise.

Avoid excessive rainfall (rainy season). Avoid picking plants during or after rainfall because rain washes away lactic acid bacteria and yeast on the leaves. If FPJ is made during this time, the juice can become sticky and thick, and won’t ferment well. This is the same reason why the ingredients should not be washed before fermentation. It is advised to pick plants 2 to 3 days after rain.

Avoid picking plants near the road side to prevent the polluted plants.
