Abstract

This research is an experimental study conducted on rice fields owned by farmers in Sembalun village and the Microbiology Laboratory of the Faculty of Agriculture at Unram. The research aims to determine the effect of fertilizer fermented with Streptomyces sp. on the growth and yield of garlic plants as well as the control of basal rot disease in garlic plants. The research was arranged using a Completely Randomized Design (CRD) consisting of 6 treatments and repeated 6 times, resulting in 36 experimental units. The six treatments are: Without fertilizer application (P0), Goat manure fertilizer without the addition of bioactivator (P1), Goat manure fertilizer + Streptomyces sp. isolate SH (P2), Goat manure fertilizer + Streptomyces sp. isolate BSi (P3), Goat manure fertilizer + Streptomyces sp. isolate BSc (P4). Goat manure fertilizer + Isolate SH + Liquid SH (P5). The research results show that the treatment with Streptomyces sp isolate BSi (P3) produced the tallest plants (57.741 cm) and was significantly different from the treatment without fertilizer. (P0). Treatment P3 also produced the highest number of leaves (10.05) significantly different from the other treatments. The highest wet and dry weight of garlic bulbs was obtained in treatment P5, which were 2.556 g and 2.343 g, respectively. The lowest intensity of Fusarium wilt disease was obtained in treatment P4, which was 6.33%, and it was significantly different from P0 or without fertilizer treatment.

Abstract

Seed Bank gulma dalam tanah terdiri atas berbagai species dengan jumlah yang sangat banyak. Kedalaman letak seed bank gulma dapat menjadi dasar untuk mengetahui tingkat persaingan gulma yang memengaruhi hasil tanaman pokok. Penelitian bertujuan untuk mengetahui komposisi dan kepadatan seed bank gulma pada berbagai kedalaman tanah pertanaman palawija di Desa Anyar, Lombok Utara. Pengambilan sampel dilakukan di pertanaman jagung, kedelai dan kacang tanah pada kedalaman tanah: 0 - 10 cm, 10 - 15 cm, 15 - 20 cm, 20 - 25 cm dan 25 - 30 cm. Parameter yang diamati adalah jumlah gulma yang tumbuh, komposisi gulma yang tumbuh dan waktu tumbuh gulma setiap kedalaman tanah. Ada perbedaan komposisi dan kepadatan seed bank yang signifikan pada berbagai kedalaman tanah di areal pertanaman palawija. Hal ini tampak dari jumlah spesies, jumlah populasi dan kemampuan tumbuh serempak yang tertinggi dari seed bank gulma terjadi pada tanah dari pertanaman jagung dengan kedalaman 0 - 10 cm dan 10 - 25 cm, kemudian semakin menurun pada kedalaman tanah 20 - 25 cm dan signifikan paling rendah terjadi pada kedalaman tanah 25 - 30 cm. Komposisi, kerapatan dan waktu tumbuh gulma semakin menurun dengan kedalaman tanah yang semakin dalam.

Abstract

The sweetpotato weevil (Cylas spp.) is one of the major pests of sweet potato that can reduce both the quality and quantity of yield, as it attacks not only the tubers but also acts as a stem borer. This study aimed to determine the effect of mulch application on the attack intensity of Cylas spp. on purple-fleshed sweet potato (Ipomoea batatas), to examine the distribution pattern of pest populations on tubers and stems, and to analyze the relationship between pest population and the resulting attack intensity. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control (F0), plastic mulch (F1), and straw mulch (F2), each replicated nine times, resulting in 27 experimental units. The results showed that the application of different types of mulch did not significantly affect the attack intensity of the sweetpotato weevil. Nevertheless, the straw mulch treatment produced the lowest attack intensity at 4.07%, followed by the control at 4.99%, and plastic mulch at 5.13%, with all treatments classified under the mild attack category (intensity below 10%). Cylas populations were found attacking both tubers and stems, with the highest population recorded in the control treatment (10.33 individuals on tubers and 5.00 individuals on stems), followed by straw mulch (4.33 and 2.56 individuals), and the lowest in plastic mulch (3.67 and 0.78 individuals). Pest populations on tubers were consistently higher than on stems, indicating that tubers are the primary target of adult Cylas spp. attack. Correlation analysis revealed a positive relationship between pest population and attack intensity, although classified as weak, with a correlation coefficient (R) of 0.314, indicating that an increase in pest population tends to be followed by an increase in attack intensity, although not consistently strong.

Abstract

This community service program was conducted from April to June 2026 in collaboration with the Karya Usaha Bersama Farmers Association (Gapoktan) in Moncok Karya, Ampenan Village, involving 20 farmers as participants. The program aimed to enhance farmers' knowledge and skills in the production of mycorrhiza-enriched bioameliorants derived from cattle manure waste and their application in glutinous corn cultivation. The activities were implemented through lectures, Focus Group Discussions (FGDs), and community empowerment approaches. A demonstration plot covering 400 m² of sandy soil was established to evaluate the application of the mycorrhizal bioameliorant under field conditions. Upon completion of the program, participating farmers demonstrated improved theoretical understanding of mycorrhizal bioameliorant production as well as enhanced practical knowledge and skills in its application on sandy soils. The cultivated glutinous corn exhibited vigorous growth and improved productivity. Furthermore, the partner farmer group actively participated in all stages of the program, contributing to the successful implementation and adoption of the introduced technology.
