Abstract

The objective of this study was to investigate the effect of photoperiod, indole acetic acid (IAA), and phosphorus on soybean plant growth and seed quality during storage. The trial was carried out at Sebapo Experimental Station, Jambi, Center for Post Harvest Research and Development, The Ministry of Agriculture and Center for Forest Research and Development, The Ministry of Forestry, Bogor from November 2009 until June 2010. Split-split plot design was used consisted of three factors, i.e. photoperiods (12 and 14 hours 54 minutes) as the main plot, concentrations of IAA (0, 75, and 150 ppm) as subplot, and dosages of phosphorus (0, 60, and 120 kg P2O5 ha-1) as subplot. The result showed that photoperiod, IAA, and phosphorus application had significantly improved production and seed quality. The path analysis showed that the weight of 1,000 seeds affected other variables. The seed protein content has the largest path coefficient compared to other variables. The treatment of mother plant with 14 hours 54 minutes photoperiod combined with IAA of 150 ppm and P2O5 of 120 kg ha-1 resulted in the highest seed quality during 90 days of storage in room temperature.

Abstract

Production of high quality seed is one of the key factors for soybean self-sufficiency. The study was aimed to produce high quality soybean seed from zero waste system. The trial was carried out at Sebapo Experimental Station, Jambi, Center for Agricultural Post Harvest Research and Development, and Center for Agricultural Land Resources Research and Development, The Ministry of Agriculture, Bogor, from January until October 2017. The experiment used a complete randomized design with a treatments combination both organic nutrient of composted soybean litter (5 tons ha-1) and inorganic nutrient (25 kg Nitrogen ha-1, 50 kg P2O5 ha-1, and 50 kg K2O ha-1). The treatments were designed as follow : K0 (control), K1 (100% organic), K2 (75% organic + 25% inorganic), K3 (50% organic + 50% inorganic), K4 (25% organic + 75% inorganic), and K5 (100% inorganic). The results showed that the treatment K3 produced the highest seed production (1.72 tons ha-1) and the highest 1,000 seed weight (147.71 g). After 3 months storage at room temperature, the seed with treatment K3 could maintain its quality with indicator 1,000 seed weight (140.98 g), 10.82% water content, 34.98% protein content, 57.42 μScm-1g-1 electrical conductivity, 80.98% germination percentage and 27.48% etmal-1 rate of germination speed.Keywords: Compost, litter, seed technology
