Other claims from this paper (9)
- Intervention effect At higher nitrogen concentration, nonnodulating soybeans produced more vegetative growth, except Tol-0.
- Observation The maximum vegetative growth of Tol-0 was almost attained at 50 ppm nitrogen.
- Association Isogenic pairs of nodulating and nonnodulating soybeans showed no significant difference in vegetative growth or seed yield at 400 ppm nitrogen, except one pair.
- Intervention effect In nodulating soybeans, vegetative growth was greater at high nitrogen (200 and 400 ppm) than at low nitrogen (12.5 and 50 ppm), except T202 and Tachisuzunari.
- Association Nitrogen-responsive soybean varieties had low seed yields at low nitrogen concentration.
- Association Nitrogen-responsive soybean varieties did not surpass the seed yields of other varieties even at high nitrogen concentration.
- Association Norin No. 2 and Tachisuzunari had more nodule number and dry weight at low nitrogen than the other varieties.
- Intervention effect Accumulated nitrogen at the early pod filling stage increased with higher applied nitrogen in all nodulating soybeans.
- Association At low nitrogen, accumulated nitrogen was larger in varieties that did not respond well to nitrogen than in responsive varieties.
