Kesesuaian Genotipe Kedelai untuk Tanaman Sela di Bawah Tegakan Pohon Karet

This research was aimed to identify shade-tolerant soybean genotypes that was suitable for planting under rubber tree plantation. The research was conducted at three locations of rubber tree plantation in Central and East Lampung where the rubber tree were at age of 3 to 4 years, during dry season of 2011. The materials consisted of 30 soybean genotypes, where 23 lines were shadetolerant, and seven were as check varieties (Pangrango, Burangrang, Malabar, Argomulyo, Grobogan, Ijen, and Tanggamus). Each genotype was planted in plot of 4 m x 2.2 m, plant spacing was 40 cm x 15 cm, two plants /hill. The experiment used a randomized block design, repeated four times. Before planting, dolomite of 1.5 t/ha was applied, and 75 kg Urea / ha + 100 SP36 kg/ha + 100 kg KCl /ha was applied at planting time. Observations were done on flowering date, harvesting date, plant height, number of branches, number of reproductive nodes, number of pods, seed weight per plant and grain yield. The light intensity under the rubber tree canopy was observed every week after the soybean age was 30 days (DAP), at 11:00 to 12:00 pm. The levels of shade made by the rubber tree canopy at three locations were different; at Tulangbalak (East Lampung) and Gunungsari (Central Lampung) ranged between 20% to 40%, at Gunungadi (Central Lampung) between 40% to 60%. Genotypes IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 yielded consistently well in two locations, in East Lampung (1.40 t/ha and 1.43 t/ha), in Central Lampung (1.19 t/ha and 1.18 t/ha). Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 produced the highest average yield out of the three locations, i.e 1.13 t/ha. Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 were considered as suitable genotypes for planting under the rubber tree of 3 to 4 years of age.

Ideal land for growing rubber tree has increasingly limited. Hence farmers and companies were looking for alternative planting of rubber tree in non-conventional areas such as the land of tidal swamps. The study was conducted at Bangun Harjo Village, Air Sugihan Regency, Ogan Komering Ilir (OKI) District, South Sumatera Province, Indonesia from 2005 to 2014. The study was aimed to test the adaptability of six rubber clones in tidal swamps. The design used was a Randomized Block Design with rubber clones as treatment and three replications. Clones planted were IRR 39, IRR 118, IRR 220, PB 260, RRIC 100, dan BPM 24. In each treatment there were 40 rubber trees and 15 rubber trees as samples. The parameters observed were stem girth, bark thickness, and latex yield. The data were statistically analyzed using ANOVA, followed by Duncan Multiple Ranges Test (DMRT) at 5% levels. The results showed that rubber trees in tidal swamps would be able to mature tapping at the age of 60 month after planting (5 years) as long as using the recommended treatment. The growth of stems of each clone at the age of 12-60 month after planting in tidal land have different growth response. However, at the age of 60 BST the highest significant girth growth was IRR 39 (48.66 cm) while the lowest was the BPM 24 (44.17 cm) clone. The average yield per tree per taping (g/t/t) from 1st to 3rd years the highest was IRR 220 (26.23 g/t/t) and the lowest was IRR 39 (15.85 g/t/t). IRR 220 is adapted to tidal swamps.Keyword: Adaptability, rubber clones, tidal swamps, growth AbstrakLahan yang ideal untuk pertumbuhan tanaman karet semakin terbatas sehingga banyak petani dan perusahaan mencari lahan alternatif untuk pengembangan karet di daerah non-konvensional seperti lahan pasang surut.

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

Background: Pod shattering has become the major problem in soybean production. The research aims to identify the pod shattering resistance and to assess the agronomic performances of 50 soybean genotypes and the association among agronomic characters. Methods: The research materials were 50 soybean genotypes which consisted of 47 lines derived from routine crossing programs and three check cultivars. The field experiment was arranged in a randomized block design with two replications. The data were observed for yield and its component traits. The oven-dry method was performed in the laboratory to assess the pod shattering resistance. Result: Variation among genotypes was found in the pod shattering resistance and agronomic characters. The genotype by trait biplot graph showed that pod shattering was negatively correlated with the days to maturity and plant height, but positively correlated with the seed size. Soybean genotypes of Grob/G100H-1-588 and G100H/Mhmr-4-993 were resistant to pod shattering and have a high seed weight per plant. These genotypes were potential for further varietal development or could be used as gene sources in the soybean improvement program for pod shattering resistance.
