CASTOLDI, Renata et al. Performance of four vegetable soybean genotypes in two agricultural years. Hortic. Bras. [online]. 2009, vol.27, n.2, pp. 256-259. ISSN 0102-0536. http://dx.doi.org/10.1590/S0102-05362009000200024.
The performance of vegetable soybean genotypes was evaluated in two years, in the experimental area of Universidade Estadual de São Paulo, São Paulo State, Brazil. The experimental design was of randomized blocks, with four genotypes and five replications per each year. Plots comprised of four rows, with three meters in length and the plants were arranged with a plant spacing of 0.10m and 0.60m between rows, where 20 plants per plot were studied. Seeds were sown in expanded polystyrene trays with 128 pyramidal cells, with the substrate Plantmax Hortaliças®. Transplanting was performed ten days after sowing, in a soil previously fertilized as recommended for the crop. Harvesting was performed when pods reached the reproductive stage R6. The genotypes JLM003; JLM010; JLM018 and CNPSoI were evaluated to measure the insertion height of first pod, mean number of pods per plant, mean number of seeds per pod, production of pods per plant, fresh weight of 100 grains and total yield of immature grains. Genotypes JLM003, JLM010 and CNPSoI were the most productive and sowing date in December showed greater yield than sowing in September.
