Abstract. Suntoro S, Herdiansyah G, Widijanto H, Wardhana HR, Tjahjanto AD, Puspitasari C, Julianto EA, Maroeto. 2024. Influence of local potential plant biodiversity as green manure on soil total N, N uptake, and chlorophyll content of rice plants. Biodiversitas 25: 1655-1662. Continuous use of chemical fertilizers in the agricultural sector causes several problems. One of several solutions that can be offered is using green manure, which could restore soil fertility and be way more sustainable for the environment. A few criteria for plants to be made into green manure are having a fast decomposition process and a low C/N ratio. This research aims to discover local potential green manure based on nutrient content and response to rice plants' soil total N, N uptake, and chlorophyll content. This research used the experiment method with a single factor Randomized Completely Block Design. There were 10 treatments with 3 replications, namely P0: control; P1: NPK 200 kg/ha; P2: Rice straw 10 tons/ha; P3: Chromolaena 10 tons/ha; P4: Ipomoea 10 tons/ha; P5: Eichhornia 10 tons/ha; P6: NPK 100 kg/ha + Rice straw 5 tons/ha; P7: NPK 100 kg/ha + Chromolaena 5 tons/ha; P8: NPK 100 kg/ha + Ipomoea 5 tons/ha; P9: NPK 100 kg/ha + Eichhornia 5 tons/ha. The results showed that Chromolaena, Ipomoea, and Eichhornia have the potential to be developed as green manure because they have high N nutrient content and low C/N ratio. These three green manures can balance the NPK fertilizer and significantly increase soil total-N content, N uptake, and chlorophyll levels in rice plants. They also provide N nutrients, N uptake, and chlorophyll levels in rice plants.

Abstract. Rahayu, Herawati A, Herdiansyah G, Putri RAAAK, Sofyan A, Muttaqin Q. 2024. Assessment of morphological characteristics and quality of turfgrass Zoysia matrella accessions from Indonesia. Biodiversitas 25: 4950-4960. Zoysia matrella is a popular turfgrass species suitable for tropical climates, including Indonesia. However, there are challenges related to the selection of accessions that produce the best quality. This research aimed to assess the morphological characteristics and visual and functional quality of turfgrass Z. matrella collected from various origins in Indonesia. The study combined exploratory surveys to collect Z. matrella accessions across Indonesia and was continued by laboratory experiments at Universitas Sebelas Maret, Central Java, using a Completely Randomized Design (CRD). We used 16 accessions of Z. matrella from 8 provinces in Indonesia to be compared with two commercials, imported accessions as controls. Results showed that Z. matrella accession from Sampit, Central Kalimantan showed the highest plant height of 10.22 cm, the longest root length of 15.72 cm, and the percentage of coverage was 94.06%. Conversely, accession from Marina Semarang had the shortest plant height of 8.35 cm with a percentage of cover of 72.75%. Some local accessions of Z. matrella had comparable visual and functional quality, growth, and morphology characteristics to the commercialized accessions, opening possibilities for the development of new, high-quality Z. matrella cultivars native to Indonesia.
