PENGARUH KETEBALAN MULSA ORGANIK KI RINYUH (Chromolaena odorata) TERHADAP PERTUMBUHAN RUMPUT MULATO (Brachiaria hybrid cv. Mulato) PANEN KEDUA

Abstrak

Penelitian bertujuan untuk mengetahui pengaruh ketebalan mulsa organik ki rinyuh (Chromolaena odorata) terhadap Pertumbuhan rumput Mulato (Brachiaria hybrid cv. Mulato) panen ke-2, dilaksanakan di Lahan Laboratorium Lapangan Program Studi Fakultas Peternakan, Kelautan dan Perikanan Universitas Nusa Cendana. Penelitian menggunakan metode percobaan dengan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan, total ada 16 unit percobaan. Perlakuan yang diuji adalah ketebalan mulsa organik ki rinyuh yang terdiri dari M0= tanpa mulsa (perlakuan kontrol), M1= ketebalan mulsa 1 cm (520 gram/0,562 m2), M3 = ketebalan mulsa 3 cm (1560 gram/0,562 m2), M5= ketebalan mulsa 5 cm (2600 gram/0,562 M2). Variabel yang diteliti adalah tinggi tanaman, jumlah anakan, jumlah daun. Data di Analisis dengan sidik ragam (ANOVA) dan uji lanjut Duncan. Hasil analisis ragam (ANOVA) menunjukan bahwa perlakuan berpengaruh tidak nyata (P>0,05) terhadap tinggi tanaman dan jumlah anakan, namun berpengaruh nyata (P<0,05) terhadap jumlah daun rumput mulato Brachiaria hybrid cv.Mulato pada panen kedua. Hasil uji Duncan menunjukan bahwa jumlah daun antar perlakuan M3 berbeda nyata (P<0,05) dibanding perlakuan M0, Namun tidak berbeda nyata (P>0,05) dengan perlakuan M1: M5 terhadap jumlah daun rumput mulato Brachiaria hybrid cv.Mulato pada panen kedua. Kesimpulannya pemberian mulsa dengan ketebalan 5 cm (2600 gram/ 0,562 m2 ) menghasilkan performa pertumbuhan paling tinggi terhadap tinggi tanaman (28,87 cm) sedangkan jumlah anakan (56,29 anakan) dan jumlah daun (283,3 helai daun pada ketebalan 3 cm (1560) gram/0,562 m2.

This study aims to determine the effect of organic mulch thickness of ki rinyuh (Chromolaena odorata) on the growth of Mulato grass (Brachiaria hybrid cv. Mulato) during the second harvest. The research was conducted at the Field Laboratory of the Animal Husbandry, Marine, and Fisheries Study Program, Nusa Cendana University. The study utilized an experimental method with a Completely Randomized Design (CRD) comprising 4 treatments and 4 replications, totaling 16 experimental units. The treatments tested included: M0 = no mulch (control), M1 = 1 cm mulch thickness (520 grams/0.5625 m²), M2 = 3 cm mulch thickness (1560 grams/0.5625 m²), and M3 = 5 cm mulch thickness (2600 grams/0.5625 m²). The variables studied were plant height, number of tillers, and number of leaves. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's test. The results of the ANOVA indicated that the treatments had no significant effect (P>0.05) on plant height and number of tillers, but had a significant effect (P<0.05) on the number of leaves of Mulato grass during the second harvest. Duncan's test showed that the number of leaves in treatment M2 differed significantly (P<0.05) from treatment M0, but did not differ significant (P>0.05) from treatments M1 and M3 regarding the number of leaves of Mulato grass during the second harvest. In conclusion, the application of mulch with a thickness of 5 cm (2600 grams/0.5625 m²) resulted in the highest growth performance in terms of plant height (28.87 cm), while the highest number of tillers (56.29) and number of leaves (283.3 leaves) were observed at a thickness of 3 cm (1560 grams/0.562 m²).
