Pengaruh Ketinggian Tempat terhadap Performa Fisiologis Tanaman Kelapa Sawit (Elaeis Guineensis Jacq.)

Abstract: Saat ini, tercatat lebih dari 10.000 hektar tanaman kelapa sawit di Indonesia telah dikembangkan pada lahan dengan ketinggian tempat lebih dari 600 m di atas permukaan laut (dpl). Budidaya kelapa sawit di dataran tinggi dihadapkan pada beberapa faktor pembatas seperti rendahnya suhu, tingginya kelembaban dan curah hujan, serta terbatasnya lama penyinaran matahari. Penelitian ini bertujuan untuk mengetahui karakteristik fisiologis tanaman kelapa sawit yang dibudidayakan di empat lokasi dengan ketinggian tempat … Show more

“…This is possible because the elevation of the Bondowoso land race (Table 1) is almost the same as the elevation of the trial site in Trenggalek, so the plant growth of the Bondowoso land race is more optimum than the other land races. This phenomenon is in line with the results of [24], which informed that oil palm plants grow optimally when planted on land with elevation < 600 m above sea level, so that when planted on land with elevation > 600 m above sea level, the photosynthesis rate decreases. In 1-year-old pulai darat (Alstonia angustiloba) in Wonogiri, Central Java, elevation differences in seed source origin also significantly affected plant growth between populations [25].…”

“…The increase in productivity will not be significant after the monthly rainfall reaches 490 mm month -1 and rainy days exceed 25 rainy days year -1 [20]. Theoretically, the decline in oil palm productivity due to high rainfall is closely related to a decrease in the rate of photosynthesis because of the minimum reception of solar radiation [21]. Moreover, further research and comparisons with monthly productivity patterns in other varieties are needed to determine the leading cause of the downward trend in monthly productivity after July.…”
