Ratings of some of the soybeans adapted to Nebraska conditions are shown in Table II . Row width and plant population may alter the growth habit of soybeans enough to somewhat change the degree of branching. Branching may be beneficial if lodging is a problem or if hail is a risk. Soybean plant type ratings and emergence scores. Plant Height Taller varieties are generally more susceptible to lodging.
Shorter varieties tend to outyield taller varieties when irrigation is used.
New short varieties, which have excellent productivity, are becoming available and may prove useful for Nebraska conditions. Consult performance trial results to determine plant height characteristics of varieties. Seed Size Seed size is not directly correlated with yield potential as several smaller-seeded varieties have high yield records and vice versa. Seed size is markedly influenced by the environment during the seed enlargement period of growth. Seed size reduction caused by moisture or other stress at the seed-enlargement period can reduce yield substantially.
