PENGARUH TINGKAT NAUNGAN BERBEDA TERHADAP PERTUMBUHAN ASOSIASI Pennisetum purpureum cv. Mott DAN Centrosema pubescens

Abstract

Forage plants include this element for the development of ruminant livestock
production, because a large amount of ruminant livestock feed comes from forage plants (grass
and legumes). This study aims to determine the effect of shade levels on the growth of
Pennisetum purpureum cv.Mott and Centrosema pubescens associations. This study was
conducted for 3 months, from September to November 2024 in Sading Village, Mengwi
District, Badung Regency. The experimental design to be applied in this experiment is a
completely randomized design (CRD) divided into four treatments and seven replications, so it
is divided into 28 experimental units. While the shade level treatment used is as follows: N0:
0% shade (without paranet layer); N1: 20% shade (1 paranet layer); N2: 40% shade (2 paranet
layers); and N3: 60% shade (3 paranet layers). The observed variables are growth variables,
namely plant height, number of leaves, total number of leaves, number of branches, number of
tillers, total number of tillers and branches, and leaf chlorophyll. The results of the study
showed the effect of shade level on the growth of the association of Pennisetum purpureum
cv.Mott and Centrosema pubescens, can increase legume height, number of branches, grass
chlorophyll and total number of leaves and reduce the number of grass tillers and the number of
tillers and total branches but have not been able to develop the variables of grass height,
number of grass leaves, number of legume leaves and legume chlorophyll. According to the
findings of the study, it can be stated that the growth of the association of Pennisetum
purpureum cv. Mott and Centrosema pubescens is influenced by the level of shade and a shade
level of 20% provides the best growth

ABSTRAK

Tanaman pakan termasuk faktor penting bagi perkembangan hasil ternak ruminansia,
sebab sejumlah besar pakan ternak ruminansia bersumber pada tanaman pakan ternak (rumput
dserta leguminosa). Penelitian ini memiliki tujuan mengetahui pengaruh tingkat naungan
terhadap pertumbuhan asosiasi Pennisetum purpureum cv.Mott serta Centrosema pubescens.
Penelitian ini dilangsungkan sepanjang 3 bulan, sejak bulan September hingga November 2024
di Desa Sading, Kecamatan Mengwi, Kabupaten Badung. Rancangan percobaan yang hendak
diterapkan di peercobaan ini ialah rancangan acak lengkap (RAL) terbagi atas empat perlakuan
serta ulangan sejumlah tujuh kali, maka terbagi atas 28 unit percobaan. Sedangkan perlakuan
tingkat naungan yang digunakan sebagai berikut: N0: Naungan 0% (tanpa lapis paranet); N1:
Naungan 20% (1 lapis paranet); N2: Naungan 40% (2 lapis paranet); serta N3: Naungan 60% (3
lapis paranet). Variabel yang diamati ialah variabel pertumbuhan merupakan tinggi
tanaman,jumlah daun, jumlah daun total, jumlah cabang jumlah anakan, total jumlah anakan
dan cabang, dan klorofil daun. Hasil penelitian menunjukkan pengaruh tingkat naungan
terhadap pertumbuhan asosiasi Pennisetum purpureum cv.Mott dan Centrosema pubescens,
dapat menambah tinggi legum, jumlah cabang, klorofil rumput dan jumlah daun total serta
menurunkan jumlah anakan rumput dan jumlah anakaan dan cabang total namun belum sanggu
mengembangkan variabel tinggi rumput, jumlah daun rumput, jumlah daun legum dan klorofil
legum. Menurut temuan penelitian bisa dinyatakan jika pertumbuhan asosiasi Pennisetum
purpureum cv. Mott dan Centrosema pubescens dipengaruhi oleh tingkat naungan yang dan
tingkat naungan 20% memberikan pertumbuhan yang terbaik.
