Influence of seed size on growth and yield of soybean plants

Maria Luiza Carvalho Carelli²; Joel Irineu Fahl

SUMMARY

Soybean seeds of the santa-rosa cultivar, classified through a 15/64 in. mesh screen (small) and 17/64 in. (large) were planted in pots, in the greenhouse and in the field. From the greenhouse plants, samples were taken 70 and 180 days after planting. In the first sample the following yield components were measured: dry weight of the empty pods number of pods and seeds, and seed weight. Under field conditions only the grain yield was weigted.

The results showed that the seed size apparently did not influence the plant growth under greenhouse conditions. The yield obtained in the greenhouse was proportional to seed size. Under field conditions there was no difference in grain yield between the plots of the two seed sizes.
