The field experiments were conducted in Prusy (near Krakow) to describe the effects of a growing season and different harvest dates on seed and protein yields and amino acid composition of two Polish cultivars of soybean.

The most favourable dare of harvest, ensuring high yields and high quality of grain, was the first half of September.
