Soybean (Glycine max L. Merrill) is an essential commodity due to its protein content and it is also as functional food which contains isoflavon as an antioxidants. Import policy is handled when there is a high demand of soybean in local market but lack of local production. This research aimed to study growth and yield of three soybean varieties with differens watering intervals in paddy field under dry climate. This research was conducted in Sesela Village, Gunung Sari Sub District, District of West Lombok, Nusa Tenggara Barat Province from July to October 2015. This research used split plot design with three replications. The main plot was irrigation intervals every (2, 9, 16, 23, 30 days) and the sub plot was soybean varieties (Anjasmoro, Burangrang, and Tanggamus). The results showed that interaction between irrigation interval and varieties influenced plant growth and yield, such as plant height, number of leaves, leaf area, 100 seeds weight and number of productive pod. Tanggamus variety has the highest number of pods of 146.33 and yield (4.2 ton ha-1) in paddy field. <br /><br />Keywords: number of leaves, productive pod, variety, yield<em></em><em></em>
Abstract. Hidayah BN, Herawati N, Aisah AR, Utami NR. 2021. Diversity of fungi associated with rhizosphere of healthy and diseased garlic crop. Biodiversitas 22: 1433-1440. Garlic (Allium sativum L.) is an especially important horticultural crop in Indonesia because it is used as a cooking spice and for medicines and cosmetic ingredients. It is mostly grown in irrigated highlands; however Indonesian production is only supplying at most 17.5% of domestic demand. West Nusa Tenggara (WNT) Province is one of the largest garlic-producing regions in Indonesia. Currently, garlic cultivation in WNT Province is facing a problem of root rot disease. Therefore, it is necessary to investigate the fungi associated with garlic root rot disease. Research was conducted in June – September 2018 and samples were collected from Sembalun highlands (1200 m above sea level). Seventeen fungal isolates were collected from the rhizosphere of the garlic crops and fourteen of them were identified. The fungi isolated from the rhizosphere of healthy garlic crops were from the genus Aspergillus, Penicillium, and Paecilomyces. While the fungi isolated from the rhizosphere of diseased garlic crops were from the genus Aspergillus, Penicillium, Paecilomyces, Fusarium, and Phoma. The genus Fusarium and Phoma are well known as plant pathogens.
Soybean is one of the most important food crops in Indonesia after rice and corn, due to its protein content reaches 40%. Rainfed lowland can be used as expansion planting area in hopes of obtaining high productivity with efficient inputs. In order to increase yield, it is necessary to apply the Bio-Detas input package that priorities the use of adaptive improved varieties, organic fertilizers and biological pesticides. This research aim to investigate the response of four Indonesian improved soybean varieties based on the application of Bio-Detas input package in rainfed lowland. The experiment was conducted from March to July 2018 in Pengembur Village, Central Lombok Regency of West Nusa Tenggara Province, Indonesia. The experiment was conducted using a non-factorial randomized block design with varieties as treatments, namely Argomulyo, Burangrang, Dega-1, and Dena-1. Each treatment was repeated three times therefore there were 12 experimental plots in total. Parameters observed during the vegetative and generative phases including plant height, number of branches, number of leaves, number of nodus, number of flowers and number of pods. Data were collected from five plants for each replication. Results showed that varieties had a significant influence on the number of leaves, number of nodus and number of flowers during the vegetative phase. While during the generative phase there were a significant effect of varieties on plant height, number of leaves and number of nodus. Due to dry season occurred earlier in April, yield on Bio-Detas input package was reached 578 kg/ha compared to farmer’s existing technology was 393 kg/ha.
