Increasing soybean production can be done by growing the crops in marginal soil, such as saline soil. Therefore, saline-tolerant genotypes are important to support the cultivation. The objective of the experiment was to evaluate the performance of 18 soybean varieties grown under salinity stress. The experiment was done from May to July 2021 at the greenhouse of the Department of Agronomy, Faculty of Agriculture, Bengkulu University, about 10 m above sea level. Soybean seedlings were grown in 10 cm diameter plastic pots fertilized with AB-mix solutions supplemented with 0 or 6 dSm-1 NaCl for 15 days. The growth and stress-tolerant index of the seedlings were measured. The results showed that soybean variety had different growth as responses to salinity. Moreover, salinity stress imposed at 6 dSm-1 NaCl significantly reduced crops growth and promoted leaf senescence. We found that 18 soybeans varieties were classified as salinity tolerant at 6 dSm-1.

Rindu Hati merupakan desa yang dinobatkan sebagai desa wisata. Kondisi objek wisata Desa Rindu Hati saat ini membutuhkan pengembangan untuk lebih banyak menarik wisatawan. Penambahan objek wisata juga menjaga agar Desa Rindu Hati tetap menjadi pilihan orang-orang untuk tetap berekreasi. Rainbow Vertical Garden merupakan konsep agrowisata berbentuk taman mini yang berisi bunga berwarna warni yang digantung pada dinding penegak. Tujuan kegiatan pengabdian ini adalah untuk memperkenalkan dan meningkatkan perkembangan kepariwisataan Desa Rindu Hati sebagai Desa Wisata dengan pengembangan objek wisata baru yaitu Rainbow Vertical Garden. Permasalahan yang dihadapi di desa Rindu Hati adalah pengembangan objek wisata belum ada pengembangan agrowisata yang berbasis pertanian di Desa Rindu Hati. Sasaran utama dari program pengabdian pembinaan ini yaitu Pengelola Wisata Desa Rindu Hati dan Perangkat Desa Rindu Hati. Metode yang dilakukan oleh Tim LPPM UNIB ini merupakan konsep baru yang mengacu pada agrowisata dengan memanfaatkan tanaman hias dengan sistem  Rainbow Vertical Garden. Hasil dari kegiatan pengabdian ini adalah mengenalkan masyarakat desa Rindu Hati  tentang pemanfaatan Vertical Garden dan pengaplikasian Rainbow Vertical Garden dengan lahan vertikal di Desa Rindu Hati sebagai sebagai agrowisata baru.

[GROWTH AND YIELDS OF SORGHUM VARIETIES TREATED WITH VARIOUS DOSES OF NPK FERTILIZER IN COASTAL LAND]. Sorghum has a potential to be developed in marginal land in coastal area. Drought stress and low availability of utrients in the coastal area are the main problems in growing sorghum.  Introducing the drought tolerance variety is one solution to overcome the drought stress in coastal land in order to improve sorghum yields. In addition, the treatment of NPK fertilizer is needed to fulfill the nutrients requirements for growth and yields. This research aims to determine the best sorghum variety and an appropriate dose of NPK fertilizer for the growing sorghum in coastal land. Field experiment was conducted at the coastal area in Bengkulu City from August until November 2021. The experiment was arranged in Randomized Completely Blok Design with two factors. That were sorghum varieties (Numbu, Super 2 and Kawali) and NPK fertilizer doses (150 kg/ha, 300 kg/ha and 450 kg/ha). The results showed that the interaction between sorghum variety and NPK fertilizer dose were not significant on the growth and sorghum yields. Numbu varieties produced the highest panicle weight per plant of 69.42 gram. The research concluded that Numbu variety showed the best growth and yields compare two other varieties. The  maximum growth and yield  of sorghum in coastal land were observed at NPK 450 kg/ha dose.

The low area for soybean plantation is still a major problem in meeting soybean needs. One of the efforts to increase national soybean production is by expanding the planting area by utilizing the sandy soil area that is still not used for soybean cultivation. This research was conducted from September-November 2020 in a greenhouse of the Agronomy Laboratory, Bengkulu University. This study aims to obtain the best dose of urea and vermicompost for the growth and yield of soybean in sandy soil. The research design used a completely randomized block design with two factors and 3 replications. The first factor was the dose of urea consisting of four levels, namely U0 = 0 kg ha-1, U1 = 50 kg ha-1, U2 = 100 kg ha-1, and U3 = 150 kg ha-1. The second factor was the dose of vermicompost, namely K0 = 0 ton ha-1, K1 = 5 tons ha-1, K2 = 10 ton ha-1, and K3 = 15 ton ha-1. The measured variables were the plant growth and the yield. Soil and vermicompost analyses were carried out before the study. The results showed that there was an interaction between the vermicompost and the urea dosages. The 100 kg ha-1 urea and the 10 ton ha-1 vermicompost treatment gave the highest plant height. The 150 kg ha-1 urea dan the 15 ton ha-1 vermicompost treatment formed the most number of branches. The highest soybean yield was given by 15 ton ha-1 vermicompost and 50 kg ha-1 urea to the total pod and the seed weight.   Keywords: sandy soil, soybean, urea, vermicompost

Soybean cultivation in Ultisols is constrained by low soil pH and soil fertility levels. Dolomite and NPK fertilization are used to improve soil quality. The goal of this study was to find the best amounts of Dolomite and NPK fertilizer for black soybean growth and yield on Ultisols and how Dolomite and NPK fertilizers affect each other on Ultisols. This study used a completely random design (CRD) 2 factors and 3 replicates. The first factor was Dolomite with four levels: A1 = 0 ton/ha (control), A1 = 0.5 x Al-dd, A2 = 1 x Al-dd, and A3 = 1.5 x Al-dd. The second factor was NPK fertilizer with four levels: N0 = 0 kg/ha (Control), N1 = Urea 25 kg/ha, TSP 100 kg/ha, KCL 80 kg/ha, N2 = Urea 50 kg/ha, TSP 125 kg/ha, KCL 100 kg/ha, and N3 = Urea 75 kg/ha, TSP 150 kg/ha, KCL 120 kg/ha. The collected data were statistically analyzed using Analysis of Variance (ANOVA) at the 5% F level test. Research results show: 1) There is no interaction of single dose of dolomite and NPK on growth and yield of soybean Detam 4 2) Dolomite dose 1.5 times Al-dd gave the best effect on plant height and number of leaves 7 WAT and weight of 100 seeds, 3) There was no significant effect of giving NPK on soybean growth and yield except for the number of leaves 2 WAP.
