The coconut thrives in the tropics between latitudes 23°N and 23°S, at low altitudes not exceeding 600 m, where the temperature is between 22-34°C, with a mean temperature of 28°C. Dwarf coconut trees produce more fruit than tall trees do, but the coconuts are generally smaller in size. Measuring 200-250 microns in length and 20-30 microns in width, they remain underneath the periyanth (cap) of the coconut and injures by feeding on the soft paranchymatic tissues. Its entry hole is marked by chewed up tissues; feeding of the beetle is shown by bilaterally symmetrical triangular cuts on the youngest open frond. 6) Coconut Pratap,Banawali, D×T,Konkan Avishkar( D×T-2) 7) ) Arecanut Shriwardhini 8) Kokum Konkan Amruta, Konkan Hatis 9) Cinnamon Konkan Tej, Konkan Tejpatta 10) Nutmeg Konkan Sugandha,Konkan Swad, Konkan Shrimanthi 11) Banana Konkan safed velchi http://www.newtonsapple.org.uk/the-common-coconut/. However, an exclusive use of sea water is detrimental to the growth of coconuts, especially young trees. CIRAD and its Ghanaian partners have developed a resistant hybrid to replace the local variety which is very sensitive to this disease. Montpellier Université d'excellence (I-Site MUSE), Platforms in partnership for research and training, Open research resources and infrastructures, A hybrid coconut to control lethal yellowing disease in Ghana, Coconut Sector Development Project (CSDP, Ghana), Oil Palm Research Institute (OPRI, Ghana), Agence française de développement (AFD, France). As the coconut tree is propagated by seed, they are subjected to some variations which can be distinguished in the trees, fruits and leaves. I think this variety was the tallest in the world, because of its hardness it would not easily break even in the strong winds.

They are also monoecious. The palm produces 12-15 inflorescences (spadices) each year at fairly regular intervals. what are the different types of coconuts according to their age? population, has been grown. The symptoms are similar to severe drought, making it difficult to recognise under drought conditions. Compared to Dwarf and Tall varieties, hybrid coconut palms have more nut yields and higher copra production (Figure 4.2). The hybrid crosses between Dwarf and Tall varieties have exhibited marked hybrid vigour by having the advantages found in both palms. The embryo is extracted on the field inside a wooden box, which provides some protection from external contaminants. India ranks at 3rd position, behind Philippines and Indonesia, in its coconut production. Generally, bearing palms are fertilized annually in areas with almost uniform rainfall distribution. How does a coconut mature? As coconuts are semi halophyte, they can grow in solutions where roots come into constant contact with salt concentrations of up to 0.6%. 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. Zoom Parts of a coconut can even be used to clean floors or to produce charcoal. Within this species, however, there are dozens of different varieties of coconuts. Symptoms include main roots showing lesions and rotting as the nematode penetrates delicate regions behind the root cap. Symptoms include leaflet yellowing, necrosis, frond collapse, premature nut fall and subsequent death. Vigour of seedlings depend upon the size of the husked nut, thickness of kernel and size of embryo present in kernel.

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. Eriophyid Mites are so minute in size that they are not visible to the naked eye. As a result, there is low yield. Salt fertilizer can also be applied to improve yields. Root wilt disease (RWD) is caused by phytoplasma. Seed nut storageCoconuts have no dormancy period between seed nut harvesting and germination. In Bangalore city and surrounding areas, these varieties are still seen in isolated places. Coconut lethal yellowing disease is one of the most serious threats to the coconut sector in Africa and the West Indies. To facilitate seedling selection when there is a large quantity of seed nuts, a two-stage nursery may be used (Figure 4.6). However, the speed of germination varies within and among coconut ecotypes and varieties. The Weligama Wilt disease is caused by a phytoplasma. It should be integrated in an overall strategy based on careful choices of planting sites beyond areas most affected by this disease, on diversification of sources of resistance, on good cropping practices and on early removal of diseased trees. The first affected inflorescences usually show partial necrosis but as the disease progresses, newer inflorescences show more extensive necrosis. Coconut genetic improvement is essential for controlling lethal yellowing disease. Fresh coconut meat can be eaten plain, grated and added to a salad or dessert, or it can be squeezed and strained to produce coconut milk for use in many tropical recipes. In most cases, the many different types of coconuts that fall between the two types are named according to where they are grown. For profitable cultivation, total rainfall of 1800-2000 mm or more per year or 150 mm per month (4-5 mm per day), evenly distributed throughout the year is ideal (Magat, 1999). Light brown speckles are also found on the petiole bases of the youngest leaves. Common examples are as follow: Rhinoceros beetle (Figure 4.8 and 4.9) attacks coconut palms in all stages of growth especially young palms which can be killed.
