Abstract

Aluminum is prevalent in soils of tidal swamps. Soybean is known to be very sensitive to aluminum stress and so when tidal swamps are converted to soybean cropland, considerable effort and expense are required to overcome Al toxicity in soybean roots. It is therefore necessary to determine at what time in early development soybeans can best endure aluminum stress and identify aluminum-tolerant cultivars. This study was conducted by testing the impact of aluminum exposure on three soybean cultivars (Tanggamus, Karasumame, and M652) (relative to no-exposure controls) at four time periods at 10, 20, and 30 days after planting. No significant effect of aluminum on root growth in the first five days after exposure was observed, but the toxic effects became evident after soybeans had been exposed to aluminum for 10 days. Soybean seedlings that experienced aluminum stress earliest (at 10 days after planting) were more negatively impacted by Al exposure than seedlings exposed later (e.g., 30 days after planting). Root growths of the three cultivars we tested in this study were all detrimentally impacted by aluminum exposure. However, the M652 cultivar was the most sensitive to aluminum exposure. We conclude that the critical threshold period for soybean root growth to succumb to aluminum stress is within the first 30 days after planting, whereas the tolerance to aluminum stress occurs only during the first 10 days of exposure.

Abstract

Oil palm fronds have huge potential to be developed as a source of organic fertiliser by chopping hard frond to become soft smooth pieces and ready to be proceed in bokashi fertilising system. This research aimed to evaluate the application of oil palm frond organic fertiliser on soybean growth and yield compared to cow manure and chemical fertilisers. Three levels of Nitrogen were applied 60, 90 and 120 kg of N/ha. This study had been done in Padang Rambun village, Seluma District, Bengkulu Province under wet land rice field condition and using rice-soybean rotation. Split plot design and least significant design (LSD) 5% were applied to analyse the data. The results showed that kinds and dosage levels gave very significant effect to all parameters but there was no significant effect between them. LSD analysis proved that oil palm frond organic fertiliser was better than manure bokashi in term of plant height and number of pods but had no significant effect on weight of seeds per plot. Furthermore, increasing of nitrogen level improved growth and yield of soybean meaning that the dosage given did not meet the optimum level for soybean growth and yield.
