I.   Introduction
        Coconut (Cocos nucifera L.) is often referred to as Kalpa Vriksha in ancient Indian
 literature, meaning "the tree that provides all necessities of life." It is also known as "the tree
 of life" or "the tree of wealth" in many parts of the world due to its wide range of uses and
 economic value. Coconut provides food, oil, water, fiber, and ornamental value to millions of
 people globally (Rieger, 2006). The term “coconut” can refer to the whole palm, the seed, or
 the fruit, which is botanically classified as a drupe rather than a true nut (Foale, 2003).
        Coconut belongs to the palm family (Arecaceae or Palmae), which includes
 approximately 2,800 species across 190 genera. Other economically significant members of
 this family include the African oil palm (Elaeis guineensis), babassu (Attalea cohune),
 arecanut (Areca catechu), and peach palm (Bactris gasipaes) (Persley, 1992). Coconut is
 unique among major crop species as it lacks closely related wild relatives, which makes the
 study of its adaptability even more crucial (DebMandal & Mandal, 2011).
        Typically, coconut grows well in lowland tropical regions with high temperatures,
 high humidity, and well-drained soils. However, with increasing interest in climate-resilient
 agriculture and crop diversification, researchers and farmers are exploring the possibility of
 growing coconut in non-traditional environments.The municipality of La Trinidad, located
 in the province of Benguet in the Philippines, offers a distinct highland environment. It
 features cooler temperatures, higher elevation, and unique soil and climatic conditions. These
 factors may influence germination, seedling vigor, and early growth performance.
 Understanding how coconut seedlings respond to such conditions can provide insights into
 their adaptability and potential for successful cultivation in upland areas.
        Therefore, this study aims to assess the germination and early growth of coconut
 seedlings under La Trinidad conditions. The results are expected to contribute to expanding
 coconut cultivation into highland zones and improving strategies for managing coconut
 production in cooler climates.
 II.      Objectives
          1. To observe the growth performance of coconut seed nuts under cool conditions
III.       Materials and Methods
               The coconut seedlings were placed close together under the same conditions to make it
       easier to measure the size and number of their leaves accurately. These measurements were taken
       once a week

 Table 1 shows the initial and final shoot lengths of nine coconut seedlings grown in cooler
 conditions. The results reveal a large variation in growth, suggesting that cool conditions do not
 always lead to consistent or successful growth. While some seedlings (samples 1, 3, and 6) grew
 well, others (samples 7, 8, and 9) showed little or no growth, and three of these even died. This
 indicates that cooler conditions may have negatively affected the growth and survival of some
 seedlings. The mixed results emphasize how sensitive coconut seedlings are to environmental
 factors and highlight the need for more research to find the best conditions for growing coconut
 seedlings in cooler climates.

Table 2 shows the initial and final heights of nine coconut seedlings grown in cool conditions.
The results vary widely, with some seedlings (samples 1, 2, 3, 4, and 5) growing well, while
others (samples 7, 8, and 9) had little or no growth, and three even died. This suggests that cool
conditions may have harmed the growth and survival of some seedlings, showing how sensitive
they are to environmental changes.

Table 3 shows the initial and final number of leaves on nine coconut seedlings grown in cool
conditions. Samples 1-6 showed leaf growth, while samples 7-9 had no growth and died, resulting
in zero leaves. Calculating the average leaf count is misleading since it doesn’t account for the
mortality of samples 7-9. A more accurate analysis would separate the growth of samples 1-6
from the death of samples 7-9, suggesting that cool conditions negatively affected both leaf
development and survival.

      Table 4 shows the weekly shoot length growth of nine coconut seedlings grown in cool
      conditions. While most seedlings showed growth, there was notable variation. Seedling 1 had
      steady growth, while seedling 9 showed minimal increase. Some seedlings, like seedling 7 on
      March 4th, 2025, even experienced a decrease in growth.
VI.      Questions to be answered
      1. Why is coconut is very important
      - Coconut is important because it provides a wide range of products used for food, oil, drink,
      shelter, fiber, fuel, and even medicine. Every part of the coconut tree can be used, making it a
      valuable resource for millions of people, especially in tropical countries. It also contributes
      significantly to the economy and livelihoods in many coconut-producing regions.
      2. What are the factors affecting growth and development of the coconut?
      - Several factors affect the growth and development of coconut trees. Climate plays a major role,
      as coconuts thrive in warm, humid, tropical environments. They grow best in well-drained sandy
      or loamy soils that are rich in nutrients. A regular and adequate water supply is essential, since
      both drought and waterlogging can negatively affect growth. Coconuts are also sensitive to
      temperature changes and do not tolerate cold conditions well. Full sunlight is necessary for
      healthy development, while essential nutrients like nitrogen, potassium, and phosphorus help
      support overall growth. Additionally, pests and diseases can significantly slow or stop
      development if not properly managed. Lastly, genetic variety also influences growth, as different
      coconut types respond differently to environmental conditions.
      3. What are the effect of growth and development?
      - Good growth and development in coconut trees lead to several positive outcomes. These
      include higher yields of fruits and copra (dried coconut meat), stronger and healthier trees
      with longer productive lifespans, and improved quality of coconut products such as oil, water,
      husk, and fiber. On the other hand, poor growth can result in low fruit production, weaker
      trees, and significant economic losses for farmers and communities that rely on coconut as a
      source of income and livelihood.
      4. Why coconut is consider as tree of life ?
      Fruit – Provides water, food, and oil.
      Leaves – Used for roofing, mats, and baskets.
      Trunk – Used for timber and building materials.
      Husk – Used for coir (fiber), ropes, and brushes.
      Roots – Sometimes used in traditional medicine or as a natural dye. Its wide usefulness
      makes it essential in daily life, especially in tropical communities.
VII.       Conclusion
               In conclusion, planting coconut is a valuable agricultural practice, especially in tropical
       regions where the crop thrives. With proper care, including suitable climate, well-drained soil,
       regular watering, and protection from pests and diseases, coconut trees can grow strong and
       productive. Their many uses—from food and drink to materials and medicine—make them an
       essential resource for both local communities and economies. However, successful coconut
       farming requires careful attention to environmental conditions and ongoing management to ensure
       healthy growth and high yields. With the right practices, coconut planting can be both sustainable
       and highly rewarding.
VIII.      Recommendations
               It is recommended that coconut seedlings be planted in warm, sunny areas with well-
       drained, fertile soil to support healthy growth. Regular watering and proper spacing should be
       practiced to avoid overcrowding and ensure each plant gets enough nutrients and sunlight.
       Farmers should monitor for pests and diseases and apply appropriate control measures when
       needed. Using high-quality planting materials and selecting the right coconut variety for the local
       climate can also improve survival and yield. Finally, further research and training on best
       practices for coconut cultivation, especially in cooler or changing climates, will help improve
       success in growing healthy and productive coconut trees.
