Abstract

Sistem pertanian budidaya di Tarakan Timur didominasi tanaman hortikultura yang rentan terhadap serangan Organisme Pengganggu Tanaman sehingga berakibat pada penurunan produksi. Salah satu OPT yang berkaitan langsung dengan budidaya hortikultura adalah gulma dengan segala jenis, dampak, dan biologinya. Oleh sebab itu perlu tindakan identifikasi. Penelitian ini bertujuan untuk melakukan identifikasi gulma dengan mengetahui spesies gulma dan spesies gulma yang dominan dimana pelaksanaan penelitian ini pada lahan budidaya tanaman hortikultura di Kecamatan Tarakan Timur. Pengambilan sampel gulma menggunakan metode kuadrat secara acak, sebanyak 50 sampel dengan ukuran petakan 1 m x 1 m. Hasil penelitian menemukan 39 jenis gulma, 24 spesies termasuk gulma golongan berdaun lebar, 12 spesies rumputan dan 3 jenis diantaranya golongan teki. Spesies gulma dominan adalah gulma Cyperus compressus dengan nilai SDR tertinggi sebesar 23,11%.

Abstract

Eleusine indica is a dominant weed species commonly found in maize fields and can significantly suppress maize growth. The use of plant-based herbicides derived from Imperata cylindrica offers an alternative strategy for controlling E. indica. Such herbicides are considered environmentally friendly because they originate from organic materials. This study aimed to evaluate the effects of I. cylindrica weed extract on the growth of E. indica and maize plants. The experiment was conducted using a randomized complete block-design with a single factor, namely I. cylindrica extract concentration. Treatments consisted of a control (without I. cylindrica extract) and extract concentrations of 20%, 40%, 60%, 80%, and 100%. Observed variables included maize plant height, number of leaves, shoot fresh and dry weights, root fresh and dry weights, weight of husked maize ears, as well as the height, number, fresh weight, and dry weight of E. indica. Data were analyzed using analysis of variance (ANOVA), and treatments showing significant effects were further analyzed using Duncan’s Multiple Range Test (DMRT). The results showed that application of 100% I. cylindrica extract resulted in significantly lower maize plant height and a significantly reduced number of leaves compared to other treatments, except for the 80% concentration. The 100% extract treatment suppressed E. indica height by up to 10.17% and reduced the number of E. indica leaves by up to 12.5% at 2 weeks after planting. These findings indicate the potential of Imperata cylindrica as an environmentally friendly plant-based herbicide without adversely affecting the main crop.

Abstract

The root-knot nematodes Meloidogyne incognita poses a serious threat to horticultural food and plantation crops. One of the effective and efficient measures to overcome this nematode is using bacteria as a biological control agent. This study aimed to test the effectiveness of Bacillus subtilis bacteria grown on media with additional micronutrients as a biological control agent for M. incognita. The test was carried out by growing bacteria in 100 mL of nutrient broth (NB) added with FeCl2, MnCl2, and CuCl2. Each type of micronutrient was administered at concentrations of 35 ppm, 40 ppm, 45 ppm, 50 ppm, and 55 ppm. As a control, NB media was used without the addition of micronutrients. The test results showed that the best performances on bacterial growth were 55 ppm MnCl2, 45 ppm MnCl2, 40 ppm MnCl2, 40 ppm CuCl2, 50 ppm MnCl2, and 35 ppm MnCl2. These six treatments were then used in an antagonism test. A total of 150 J2 M. incognita in 4 mL of suspension was put into a petri dish with a diameter of 5 cm. After that, 1 mL of each bacterial suspension was put into a petri dish following the treatment. The mortality rate of M. incognita in each treatment was 77.5% in 55 ppm MnCl2, 74.5% in 45 ppm MnCl2, 77.25% in 40 ppm MnCl2, 73.25% in 40 ppm CuCl2, 78.75% in 50 ppm MnCl2, 79% in 35 ppm MnCl2, and 53.25% in control. The same six treatments were also used to measure the chemotaxis index of M. incognita on tomato roots. Tomato seeds of the Tantyna variety were soaked for 60 minutes in a bacterial suspension grown on micronutrient-enriched media. After seven days, the tomato seed roots were removed and placed in 5 mL 20% Pluronic F-127 Gel which had been infested with 100 J2 M. incognita. After 6 hours, the number of nematodes approaching the roots was observed. The chemotaxis index in the treatments ranged from 16% to 24%, while that in the control was 33%. This study corroborates that the addition of micronutrients MnCl2 and CuCl2 to the growth medium of B. subtilis can increase antagonistic activity against M. incognita and suppress its chemotaxis response in tomato roots soaked in the bacterial suspension.
