How many coconuts per tree




















In the latter, in vitro inoculation of the embryos in the field follow steps similar to storing disinfected embryos. However, instead of being stored in potassium chloride solution, the cylinder of endosperm is directly placed in a Petri dish. The embryo is extracted on the field inside a wooden box, which provides some protection from external contaminants. Then, it is rinsed again and inoculated to a solid embryo culture medium. Next, the tube is transported to a laboratory where the embryo is allowed to grow on the culture medium.

When the first true leaf is visible and the root system starts developing at least one root with ramifications, the plantlets are transferred to light conditions.

Thereafter, plantlets are transferred to large tubes containing fresh medium every weeks. When plantlets display unfolded green leaves, they can go on to acclimatisation after months of initial inoculation.

At this stage, plantlets are removed from culture tubes and planted in the greenhouse where soil nutrition and quality are controlled. After two months, they are then transferred to plastic bags filled with forest leaf mould mixed with sand before they are planted in the field. The most rapid growth occurs between the second and fifth year of planting a coconut palm.

A stem appears under the crown after growing for years, and stem elongation reaches cm annually, but slows down in older palms which are 40 years and older. After the sixth year, fruit production increases at the expense of vegetative growth.

Thereafter, the coconut tree experiences fairly constant growth as yields are sustained over the next 40 years, and palm age can be roughly gauged from the length of the stem. A wide range of soil textures sand-clay is suitable for coconut production.

The palm tolerates soil pH from 5. For optimum growth, a pH range of 5. As one of the thirstiest denizens of the plant kingdom, water plays an indispensable role in the successful cultivation of coconut palms. As such, it is strongly advised that coconuts be planted at the start of the rainy season, or under weather conditions with a rainfall of mm evenly distributed throughout the year.

For profitable cultivation, total rainfall of mm or more per year or mm per month mm per day , evenly distributed throughout the year is ideal Magat, However, coconuts can still grow normally even with less rainfall, provided there is enough soil moisture or a high water table with good drainage.

Generally, the coconut palm absorbs 24 litres of water each day, and the daily loss of moisture from mature coconut palm varies from litres per day. However, the coconut does not like being waterlogged, and coconut palms will not survive more than two weeks of surface water logging. A persistently high humid condition is not suitable for the palm as it favors the rapid spread of Phytophthora disease fruit rot or bud rot , a fatal disease commonly observed in yellow, red or orange dwarf varieties Magat, There should also be no prolonged soil water deficit and excessive soil salinity.

As coconuts are semi halophyte, they can grow in solutions where roots come into constant contact with salt concentrations of up to 0. Therefore, it is possible to temporarily use sea water for irrigation purposes without any ill effects. However, an exclusive use of sea water is detrimental to the growth of coconuts, especially young trees.

Salt fertilizer can also be applied to improve yields. In addition, they are environmentally-friendly. The use of sodium chloride NaCl or common salt as fertilizer is a practical mean of increasing coconut production.

Salt is the cheapest and best source of chlorine to increase copra weight per nut and copra yield per tree. Generally, bearing palms are fertilized annually in areas with almost uniform rainfall distribution.

In areas with distinct wet and dry seasons, uneven rainfall distribution, and those with sandy soils, fertilizers are best applied every six months.

In a long- term study of salt application, 1. Split application is done at the pre-bearing stages of palms, equivalent to years. This practice helps reduce the loss of fertilizer nutrients through leaching and run- off, which makes the use of fertilizer more effective Magat, More importantly, the use of MNF can help to prevent mineral deficiency, which can lead to retarded root growth, delayed flowering, ripening of nuts and poor leaf health.

In turn, these may result in smaller fruits produced and lower overall yield. Monocrop or pure palms are planted at a density that allows the tips of horizontally held mature leaves to touch. The planting density is about m spacing for Dwarf palms, As a guide, Table 4. Yields vary from place to place. In general, commercial monocrop plantings out yield those in home gardens. Higher yields are obtained when there are more inputs, such as proper management, maintenance and regular fertilization.

Annual yields range from kg of copra or, depending on the fruit size, fruits per coconut palm. Coconut competes well with most plants for nutrients and water. However, its growth and yield slows in the presence of aggressive grasses such as the Imperata cylindrical. Pasture grasses, including Ischaemum aristatum, are commonly grown under old palms for cattle grazing. In general, coconuts grow poorly in shade. For instance, seedlings planted under older palms or other trees can take up to 10 years to flower with low yields.

For maximum productivity, all weeds that compete with coconut for nutrients, water, or sunlight should be suppressed. Completed Meetings. Log in Register. Search titles only. Search Advanced search….

Thread starter atulkalaskar Start date Oct 19, Hi Friends, This question is for anyone who has expertise in coconut cultivation as a grower or as an expert and I will greatly appreciate your input.

How many coconuts one can get from a fully matured say 15 years of age coconut tree? Organic, Inorganic does not matter. For a tree which gives 65 to 75 nuts per annum the following combination of manure can be prescribed.

The above combination has to be given twice a year in two equally spilt doses. Along with the above enriched farm yard manure of 25 kg. For a tree yielding to nuts per annum the manure management get enhanced:. Super Phosphate. The above combination of manure is to be given in three equally split doses in a year.

Along with the above, 1 kg. Nature of Soil. Annual Rainfall. Air and Moisture per year. Providing Water. For moisture conservation, 2 layers of coconut husk should be placed at the bottom of the pit with concave surface facing upwards while filling the pits. In-order to soften the hard pan of the soil, common salt of 2 kg per pit should be applied at least 6 months before the plantation.

Generally, a square system of planting is preferred with a spacing of 7. However, a spacing of 7. Selection of quality seedlings is very important for better yield.

Farmers should select vigorous coconut seedlings of 1 year old and having minimum of 10 cm at the collar level to plant in the farm land. Early splitting of leaves in the seedlings could be a factor of selecting good seedlings. In case of water logged areas, 18 months to 24 months old seedlings are preferred.

The best planting season in coconut farming is May to June which is pre-monsoon time frame. Propagation is done through seeds. Seedlings can be raised on nursery beds and transplanted in the main field. The regular manuring and chemical fertilizers should be carried from the first year of plantation for proper vegetative growth, early flowering and fruit bearing. The first application of in-organic fertilizers should be carried after 3 months of coconut plantation.
