Title
FERTILIZER RATES FOR YOUNG TABLE GRAPE VINEYARDS WITH DRIP IRRIGATION SYSTEMS
Alexander N. Babichev; Georgiy T. Balakay; Alexey A. Babenko; et al. Land Reclamation and Hydraulic Engineering 2024. doi:10.31774/2712-9357-2024-14-4-30-43
Other claims from this paper (9)
- Intervention effect The 20% higher mineral fertilizer dose gave the highest plant height and vine ripening indicators compared with the control variant.
- Observation Net productivity of leaf photosynthesis in the first year varied from 1.1 to 1.3 g/(sq. m·day).
- Observation Net productivity of leaf photosynthesis in the second year varied from 2.0 to 2.7 g/(sq. m·day).
- Observation Net productivity of leaf photosynthesis in the third year was 1.8–2.9 g/(sq. m·day).
- Recommendation Increasing the fertilizer rate on young grape plantations by more than 20% is inappropriate.
- Observation Yield of third-year grapes varied within 2.47–2.91 t/ha.
- Intervention effect Raising mineral fertilizer rates by 10% increased third-year grape yield by 4.7% over the control variant.
- Intervention effect Raising mineral fertilizer rates by 20% increased third-year grape yield by 9.2% over the control variant.
- Recommendation The rational fertilizer rate for young vineyards on chernozem soils is N96P72K72 in the foothill zone of Crimea.
