Site Selection and Land Preparation in Noni Fruit Cultivation:- Avoid locations where other crops have been planted recently, due to the susceptibility of Noni to root-knot nematodes. Select a site in full or partial sun with well-drained, well-aerated soil. Prepare a hole about the size of the pot and transplant it carefully. In rocky locations, plough the subsoil before grading to prepare a horizontal or gently sloping field.
If a windy site is chosen for Noni cultivation, windbreaks must be implanted for protection. Trees such as eucalyptus should be implanted to feet apart are excellent windbreaks for Noni. Remove any clods in the field and give a couple of ploughing to bring the soil to the finetilth stage. The land should be levelled to an optimum level. Remove any weeds or dried trees, rocks from the field. Propagation in Noni Fruit Cultivation:- Noni crop is relatively easy to propagate from seeds, stem or root cuttings, and air layering.
The preferred ways of propagating are by seed and by cuttings produced from the stem. Noni blossoms and fruits around the entire year. Germination in Noni Cultivation:- Noni seeds require hot, wet conditions for optimum germination. Un-scarified seeds require several months to a year before organic germination takes place, but their germination can be reduced to a month or so using heat.
Choose the warmest spot in the nursery or greenhouse to germinate Noni seeds. If germinated outside, partial sunlight is preferable to full sun to avoid excessive drying of this medium. Noni seeds may be germinated in seedling flats or trays or sown directly in containers.
A light-medium that retains water yet remains aerated is best. Suitable components to get a planting medium include vermiculite, perlite, peat moss, commercial potting media, compost , and fine volcanic cinder.
For seedling flats, use a light-medium, like one part each of perlite and peat moss, or perlite, vermiculite, and potting soil in a ratio. For containers, a slightly heavier medium is better, like one part of perlite or vermiculite and three components of a potting mix. In case if you miss this: High Density Pineapple Planting. Seed Processing, Treatment, Planting in Noni Fruit Cultivation:- After picking, allow the fruit to ripen until it seems soft and translucent. This may require 3 to 5 days if just semi-ripe fruits were accumulated.
Once the fruits have fully softened, press them against a screen, the soft, fibrous pulp will slowly be eliminated completely eliminate the clinging flesh. Rinsing in water periodically helps float off the pulp.
If the seeds are to be used immediately, tender fruits may be suspended in water and exposed to short pulses in a blender, very sparingly, to remove the majority of the flesh while slightly scarifying the seeds.
If the seeds are to be stored, the flesh ought to be removed entirely, then the seeds air-dried and stored in a paper bag in a cool room with low humidity. There are approximately 39, to 40, seeds in each kilo of Hawaiian Noni fruit. Without pre-treatment, Noni seeds germinate sporadically over 8 to 12 months.
A simple technique is to place ripe fruits in a blender and then pulse the blending mechanism a few times to reduce open the Noni seeds prior to separating them from the pulp. A more time-consuming procedure that results in a higher germination percentage consists of clipping off the tip of Noni seeds close to the embryo to allow water to penetrate the seed coat. Germination time for scarified Noni seeds is 20 to days, depending upon temperature, environment, and variety or genotype.
Weed and nematode-free natural or local forest soil mixed with sand, composted organic matter is excellent for seedling production. Most nurseries prefer natural potting media rather than commercial media for Noni production. Mulch like sawdust, leaf litter or sand can be put over the seeds for both weed control and moisture retention. Noni seeds can germinate in conditions ranging from deep shade to full sun.
Most uniform germination is achieved in the light partial shade 20 to 30 percent. Noni seedlings may be transplanted in about 2 to12 months after germination. After transplanting, the first year of seedling development is slow due to transplant shock and also the establishment of an origin program. Later, seedling growth is far more rapid since the crown gains size and photosynthetic mass.
Propagation from Stem Cuttings in Noni Cultivation:- Varying sizes of stem cuttings can be used, however, 20 cm to 40 cm cutting are manageable and effective. Stem cuttings can root in 3 weeks and be ready for transplanting in 6 to 9 weeks. As with plants derived from seeds, rooted stem cuttings may be grown in pots for up to 24 weeks or even longer with exceptional outcomes when transplanted.
However, plants require irrigation during the early stages of the crop. The frequency of irrigation depends on soil moisture condition and climate.
Note the conspicuous air chamber light brown-colored bubble in the upper-right hand portion of this seed. Noni seeds can float for many weeks. Young noni plant grown from seed in a 4-inch pot. Only soft, ripened noni fruits should be chosen for seed collection. The seeds must be separated from the fibrous, clinging fruit flesh. First, split the fruit by hand into smaller pieces. Separate the seeds from the flesh using a strong spray of water and a firm screen or colander, washing the pulp through the screen while retaining the cleaned seeds.
Rubbing the fruit fragments on the screen by hand or with a blunt object can help force the fruit flesh through the screen. It may take 15 minutes or more of vigorous washing and rubbing to detach most of the flesh from the seeds. Ripened noni fruit with seeds. A single fruit may have hundreds of seeds.
Ripened noni fruits break up easily by hand, but the pulp clings to the seeds. To obtain noni seeds for planting, they may be planted with the pulp attached, or the pulp may be separated from the seeds first. The seeds may be dried or not dried before planting.
Seed scarification. Scarifying the hard seed coat by nicking or puncturing it significantly reduces germination time, improves germination percentage, and promotes uniform sprouting. Whereas in nature the seed coat must gradually decompose before water can enter, scarification overcomes this natural seed dormancy.
Using a household blender to separate seeds from the ripened fruit flesh can also result in nicking the seed coats, or the seeds can be suspended in water and subjected to short pulses of blending.
Seed drying and storage. Noni seeds can be dried and stored, but the length of time they will remain viable is not known. After cleaning, spread the seeds out on newspaper and dry them in the shade or indoors for two or three days. Store the seeds in an air-tight container at room temperature. Fresh noni seeds can be planted immediately after extraction from the fruit. Some growers soak the seeds until they start to germinate, then plant them in containers, while others plant fresh seeds without presoaking treatment.
The seedlings are usually grown for about nine months to a year before they are transplanted to the field. Some growers just plant fruit fragments containing seeds directly into the field soil. Noni seeds require hot, wet conditions for optimum germination. Un-scarified seeds require several months to a year before natural germination takes place, but their germination can be reduced to a month or so using heat.
Select the warmest spot in the nursery or greenhouse to germinate noni seeds. If germinated outside, partial sun is preferable to full sun to avoid excessive drying of the medium. Noni seeds may be germinated in seedling flats or trays or sown directly in containers. A light medium that retains water yet remains aerated is best. Suitable components for a planting medium include vermiculite, perlite, peat moss, commercial potting media, compost, and fine volcanic cinder.

For containers, a slightly heavier medium is better, such as one part of perlite or vermiculite and three parts of a potting mix. Fertilizers should not be mixed into the medium, because additional nutrients are not needed until after the plants have their first true leaves.
Growth media. Artificial growth media are preferred to field soil for germinating and growing out noni seedlings. These relatively sterile media give the plants the cleanest start, whereas soil particularly agricultural field soil tends to contain pathogens that cause plant diseases. For example, many agricultural soils are infested with root-knot nematodes, and noni is highly susceptible to the disease known as noni root-knot disease caused by these microscopic, parasitic worms.
Growth containers. It is now grown throughout the tropics. Noni is grown in most parts of the Pacific and all parts of the plants have either traditional or modern uses. Although it has been used medicinally by Polynesians for thousands of years, commercial cultivation and processing of noni juice products is a recent, economically important development.
