Other claims from this paper (6)
- Observation In summer the total reserves of productive moisture in the 0-100 cm layer of the drained soil fell to a critical 60 mm.
- Observation The groundwater level on the drained soil dropped to 2.5-3.0 m.
- Intervention effect Under moisture deficit, the recommended mineral fertilizer norm with manure and the higher norm against a straw background gave equivalent sunflower seed yields of 2.30-2.33 t/ha.
- Intervention effect Applying the recommended rate of mineral fertilizers together with the predecessor straw decreased sunflower seed yield by 14.0% on average.
- Intervention effect Double fertilization with the chelated microfertilizer Yarilo significantly increased sunflower yield where no mineral fertilizers were used and with N60P60K90 on a straw background.
- Intervention effect The most cost-effective fertilizer system was N60P60K90 with straw and the microfertilizer Yarilo, with a profitability of 43.5% and a seed yield of 2.3 t/ha.
