Pengaruh Volume Air Terhadap Pertumbuhan Beberapa Varietas Kelapa Sawit (Elaeis Guineensis Jacq.) Umur 8 – 14 Bulan Di Pembibitan Utama
ABSTRACT
Oil palm plantation has an important role for the development of national
plantation in Indonesia, in purpose to create job opportunities that lead to
community welfare and also become the source of foreign exchange or tax for the
country. Over the last four years, the area of oil palm plantation in Indonesia has
increased from 10.4 million hectares since 2013 and continued to 12.30 million
hectares in 2017 with total production 34.47 million tons of CPO. This research
carried out at the Screen House, Experimental Garden, Faculty of Agriculture,
Universitas Riau, Bina Widya campus 12.5 Km, Simpang Baru , Tampan District,
Pekanbaru. This study took 7 months, started from May 2019 to December 2019.
This research was conducted using experimental research by applying the form of
the two-stage nested plot with the treatment arrangement of factor 2 into factor 1.
The first factor was oil palm variety which includes of 3 levels, namely V1
: Tenera DxP Marihat variety, V2 : Tenera DxP Topaz 3 variety, and V3 :
Tenera DxP Socfindo Lame variety. The second factor was the volume of water
supply which consists of 4 levels, namely A1 = 1000 ml per day per plant, A2 =
1500 ml per day per plant, A3 = 2000 ml per day per plant, and A4 =
2500 ml per day per plant. The Observation parameters are photosynthetic rate,
leaf area, seedling height, number of leaves, diminutive diameter of trunk, wet
weight, plant roots, root crown ratio, and seed quality index. The results of were
analyzed statistically using analysis of variance and with Duncan's multiple
distance test at level 5% using the SAS 9.1 application. The results showed that
the volume of water affected all growth components of several varieties of oil
palm seedlings, both on the variables of photosynthesis rate, leaf area, seedling
height, number of leaves, diminutive diameter of trunk, wet weight, plant root
volume, root crown ratio, and seed quality index. The water volume of 2000 ml of
water per day per plant has shown a good effect on the growth of the three
varieties of oil palm.
