PENGARUH TINGGI PEMOTONGAN TERHADAP PERTUMBUHAN RUMPUT GAJAH MINI (PENNISETUM PURPUREUM CV. MOTT)

Abstrak

Penelitian bertujuan melihat pengaruh tinggi pemotongan terhadap pertumbuhan rumput gajah mini. Penelitian berlokasi di Lab Lapangan  Program Studi Peternakan FPKP UNDANA selama 4 bulan. Metodenya adalah eksperimen dengan RAL 5 perlakuan 3 ulangan yaitu T1=  5 cm, T2= 10 cm, T3=  15 cm, T4=  20 cm dan T5= 25 cm. Variabelnya yaitu tinggi tanaman, jumlah daun dan jumlah anakan. Data dianalisis dengan menggunakan analisis ragam (ANOVA).  Hasil yaitu rata-rata tinggi tanaman (cm) adalah T1=60,65, T2=63,02, T3=61,63, T4=58,94, dan T5=57,16; jumlah daun (helai) adalah T1=69,9; T2=86,29; T3=90,8; T4=106,3; dan T5=101,7 dan jumlah anakan adalah T1=10,6; T2=10,9; T3=12; T4=12,46; dan T5=12,75. Sidik ragam menunjukkan perlakuan berpengaruh tidak nyata (P>0,05. Simpulan bahwa tinggi pemotongan berbeda  memberikan pengaruh relatif sama terhadap pertumbuhan rumput gajah mini.

The study aimed to examine the effect of cutting height on the growth of dwarf elephant grass. The research was conducted at the Field Laboratory of the Animal Science Study Program, FPKP UNDANA, over four months. The method used was an experimental design with a Completely Randomized Design (CRD) consisting of five treatments and three replications: T1 = 5 cm, T2 = 10 cm, T3 = 15 cm, T4 = 20 cm, and T5 = 25 cm. The variables observed were plant height, number of leaves, and number of tillers. Data were analyzed using analysis of variance (ANOVA). The results showed that the average plant height (cm) was T1 = 60.65, T2 = 63.02, T3 = 61.63, T4 = 58.94, and T5 = 57.16; the number of leaves (blades) was T1 = 69.9, T2 = 86.29, T3 = 90.8, T4 = 106.3, and T5 = 101.7; and the number of tillers was T1 = 10.6, T2 = 10.9, T3 = 12, T4 = 12.46, and T5 = 12.75. The analysis of variance indicated that the treatments had no significant effect (P>0.05). It was concluded that different cutting heights had a relatively similar impact on the growth of dwarf elephant grass.
