dc.description.abstract | Salah satu cara untuk mengendalikan gulma pada tanaman bawang merah
adalah menggunakan herbisida sintetik, namun penggunaan herbisida secara
berlebihan tidak ramah terhadap lingkungan. Senyawa yang terkandung dalam T.
indica dan C. rotundus berpotensi sebagai bioherbisida. Penelitian bertujuan
mendapatkan formulasi campuran T. indica L. Merr. dan umbi teki C. rotundus L.
yang efektif untuk mengendalikan gulma pada pertanaman bawang merah.
Percobaan disusun dalam Rancangan Kelompok Lengkap Teracak (RKLT) faktor
tunggal dengan delapan perlakuan dan empat ulangan. Perlakuan yang diuji yaitu :
tanpa penyiangan (P0), formulasi tepung C. rotundus dosis 22,5 kg ha-1 + T. indica
dosis 45 kg ha-1 (P1), formulasi pelet C. rotundus dosis 22,5 kg ha-1 + T. indica
dosis 45 kg ha-1
(P2), formulasi maserat air C. rotundus dosis 22,5 kg ha-1 + T.
indica dosis 45 kg ha-1
(P3), formulasi maserat metanol C. rotundus dosis 22,5 kg
ha-1 + T. indica dosis 45 kg ha-1
(P4), formulasi maserat metanol C. rotundus dosis
45 kg ha-1
(P5), formulasi maserat metanol T. Indica dosis 45 kg ha-1
(P6), dan
penyiangan manual (P7). Satuan percobaan berupa bedengan berukuran 5 m × 1 m.
Hasil penelitian menunjukkan bahwa aplikasi formulasi pelet, maserat metanol
dosis campuran, maserat C. rotundus, dan maserat T. indica efektif dalam menekan
pertumbuhan gulma spesies R. exaltata saat 4-6 MSA, namun tidak efektif dalam
menekan pertumbuhan gulma D. ciliaris, A. sessilis, C. rotundus dan C. dactylon.
Formulasi campuran bioherbisida yang efektif adalah formulasi pelet dan formulasi
maserat metanol. Formulasi pelet C. rotundus + T. indica dosis 22,5 kg ha-1 + 45 kg
ha-1 dapat menekan gulma total dari 57,26% hingga 64,09% sedangkan formulasi
maserat metanol C. rotundus + T. indica dosis 22,5 kg ha-1 + 45 kg ha-1 dari 48,21%
hingga 56,29%. Perlakuan berbagai formulasi bioherbisida tidak mempengaruhi
pertumbuhan tinggi tanaman, jumlah daun, dan jumlah umbi serta hasil panen
bawang merah. | id |
dc.description.abstract | One way to control weeds in shallot plants is by using synthetic herbicides,
but excessive use of herbicides is not environmentally friendly. Compounds
contained in T. indica and C. rotundus can be used as bioherbicides. The research
aimed to obtain a mixture formulation of T. indica L. Merr. and C. rotundus L.
tubers were effective in controlling weeds in shallot cultivation. The experiment
was arranged in a Completely Randomized Design (CRD) with a single factor
comprising eight treatments and four replications. The treatments tested were:
without weeding (P0), C. rotundus flour formulation at a dosage of 22.5 kg ha-1 +
T. indica dosage of 45 kg ha-1 (P1), C. rotundus pellet formulation at a dosage of
22.5 kg ha-1 + T. indica dosage of 45 kg ha-1 (P2), C. rotundus water macerate
formulation at a dosage of 22.5 kg ha-1 + T. indica dosage of 45 kg ha-1 (P3), C.
rotundus methanol macerate formulation at a dosage of 22.5 kg ha-1 + T. indica
dosage of 45 kg ha-1 (P4), C. rotundus methanol macerate formulation at a dosage
of 45 kg ha-1 (P5), T. indica methanol macerate formulation at a dosage of 45 kg
ha-1 (P6), and manual weeding (P7). The experimental unit consisted of beds
measuring 5 m × 1 m. The research results showed that the application of pellet
formulation, mixed methanol macerate dosage, C. rotundus macerate, and T. indica
macerate were effective in suppressing the growth of R. exaltata weed species at 4-
6 weeks after application (WAA), but were not effective in suppressing the growth
of D. ciliaris, A. sessilis, C. rotundus, and C. dactylon weeds. The most effective
bioherbicide formulation was the C. rotundus pellet + T. indica formulation at a
dosage of 22.5 kg ha-1 + 45 kg ha-1, which could suppress total weeds from 57.26%
to 64.09%, meanwhile the C. rotundus methanol macerate + T. indica formulation
at a dosage of 22.5 kg ha-1+ 45 kg ha-1 from 48.21% to 56.29%. Various
bioherbicide formulation treatments did not affect the plant height, number of
leaves, number of bulbs, and shallot harvest yield. | id |
