Abstract

National demand on soybean can be full filled by extending production area including marginal lands. Tidal swamp is one of marginal lands which potentially can be cultivated for soybean production with the use of tolerant varieties to waterlogging. So far, there are only two varieties that are tolerant to tidal swamp condition. This research was conducted to study the response of soybean genotypes to waterlogging and to provide gene resources in breeding for tidal tolerant variety. The research was conducted from October 2007 to February 2008 in the glasshouse of Indonesian Legume and Tuber Crops Research Institute (ILETRI), Malang. The experimental design was split-plot with two replications; where the main plot was waterlogging treatment and the sub plot was soybean genotype (17 genotypes of ILETRI collection). The results showed that soybean genotypes had different responses to different water treatments, shown on the number of branches and reproductive nodes, the number of filled and unfilled pods, and yield (dry seeds) per plant. Waterlogging inhibited plant growth of all traits. Under waterlogging, the highest number of reproductive nodes and filled pods, and yield per plant was from MLGG 0537 i.e. 12.25, 19.25, and 3.13 g plant-1, respectively.

Abstract

Performance of soybean growth and development is influenced by environmental conditions. On similar soil fertility conditions but different environmental conditions such as rainfall will also lead the changes in the performance of the plant. The research aimed to study the agronomic performance of the potential soybean lines in two different drought acid land agroecologies. The experiment was conducted at the South Lampung Tegineneng experimental station and East Lampung Taman Bogo experimental station from February until May 2013. The South Lampung Tegineneng experimental station has a pH of 5.50 and an average rainfall of 89 mm per month, and The East Lampung Taman Bogo experimental station has a pH of 5.12 and an average rainfall of 213 mm per month. The experiment consisted of 10 soybean lines adapted acid land and two check varieties. The experiment was arranged in randomized completely block design with four replications. The least significant different test (LSD) at α = 0.05 was used to calculate significant differences among all treatments. The results showed that rainfall influenced agronomic performance of soybean more than soil acidity. The yield performance in South Lampung was lower than in the East Lampung. Four genotypes produced higher grain yield than the Tanggamus variety in both locations, i.e. Tgm/Anj-862, Tgm/Anj-784, Tgm/Anj-888 Tgm/Anj-857, and Tgm/Anj-858. Tgm/Anj-862 was the most superior genotypes for having the highest number of branches, number of pods, and 100-seeds weight and seed yield and consistent at both locations. The four genotypes, especially Tgm/Anj-862, were potential to be developed in both locations or other locations with similar environmental conditions.Keywords: grain yield, ultisol, yield components

Abstract

Soybean is an important food commodity after rice and corn in Indonesia. Until now soybean demand cannot be fulfilled by domestic production, although the chances of fulfillment can be attempted. One of the attempts to increase domestic production is soybean planting in acid dry land that is widely available in Indonesia. The research aimed to obtain soybean lines that are adaptive in acid dry land. A total of 10 soybean promising lines and two check varieties (Wilis and Tanggamus) were grown in acid dry land in Tanah Laut Regency, South Kalimantan Province, Indonesia. Experimental design used was randomized complete block design with four replications. The data were analyzed using analysis of variance and followed by Least Significant Different test. The results showed that the promising lines of SC5P2P3.5.4.1-5 and SC5P2P3.23.4.1-5 achieved production of 1.51 t/ha and 1.48 t/ha, respectively. These yields were higher than Wilis and Tanggamus varieties that reached 1.41 t/ha and 1.13 t/ha, respectively. These two promising lines had the potency to be developed in Tanah Laut Regency, South Kalimantan or other areaswith similar soil characteristics.
