| The 2 attached pics show our no-till organic soybeans (first pic) and the adjacent conventional-till soybeans (second pic).
Both fields consist of 5 reps of 15' wide plots of 2 soybean varieties (Blue River Hybrids 34A7 vs 39C4).
Similar to last year, the BRH 34A7 beans are significantly taller in both fields. Last year the 39C4 yielded a little better.
Field histories are not exactly the same but both fields had triticale planted last fall. In the conventional till field, we bat-winged the headed out triticale and then worked it twice with a Howard rotavator before fitting the field for planting with a soil finisher. The conventional till field has been rotary hoed twice and row cultivated twice.
Both the no-till and conventional till plots have some velvetleaf but there is considerably more in the conventional till plots and the plants are much bigger (and harder to pull) in the conventional till plots. In the no-till plots, the velvetleaf is mostly concentrated on the north end of the field (first pic)
The conventional till plots also have quite a few waterhemps and giant foxtail but the distribution is very patchy. The waterhemps are concentrated in a ~ 50' wide strip down the middle of the 1/4 mile long field. The foxtail is concentrated in the middle third of the field with much less on the ends of the field.
Yesterday I started walking the conventional till plots and am planning to pull all the waterhemp and velvetleaf plants in these plots. We will probably do some targeted walking of the north end of the no-till field.
