Moisture deficit is a primary limiting factor in field floriculture, necessitating the adoption of highly efficient irrigation strategies. This three-year field study (2019–2021) evaluated the impact of surface drip, subsurface drip (SDI), and a prototype pulse injection irrigation system against a non-irrigated control on the biometry, corm yield, and mineral profile of Gladiolus × hybridus. Subsurface drip (SDI) and surface drip irrigation provided the most favorable and stable agronomic outcomes, particularly for daughter corm yield and quality. Conversely, pulse injection irrigation showed a highly nuanced response; while it significantly increased generative spike length by 68.5% under severe late-season drought in 2021, it failed to improve overall daughter corm mass and significantly increased plant lodging (15–20%). This performance is hypothesized to stem from localized soil structural disturbance and mechanical stress on the shallow, fibrous root system under high-pressure water delivery (4 bar). Furthermore, chemical analyses revealed that irrigation increased leaf calcium accumulation while simultaneously causing a dilution of nitrogen, phosphorus, and potassium due to increased biomass. In conclusion, SDI is highly recommended for professional gladiolus production to stabilize root-zone moisture and ensure superior commercial quality of both aerial and underground organs, while pressurized pulse injection requires further pressure-nozzle optimization to mitigate physical crop disturbance.

Seven disease control products produced at a grapevine farm in Mała Wieś (Masovian County, Poland) were tested and compared with standard chemical control and no control. The following substances were used as disease control agents: lavender, lemon, and orange oils; Saccharomyces cerevisiae HDT18 yeast fermentation liquid; mint; and Habanero Orange hot pepper decoction. Results were compared with treatments using standard fungicides, a control without control, and two commercial products containing tansy extract and chili and garlic extract. The tested products were generally less effective in protecting against fungal diseases than the standard chemical control. However, they improved total yield, yield used for vinification, total acidity, sugar content, and pH of harvested grapes compared to untreated grapes. Our own preparations (HDT-18, lemon oil, mint decoction, and hot pepper) reduced total yields and simultaneously reduced the number of grapes infected with diseases, which is particularly important in mechanical harvesting without sorting. Must parameters (sugar, pH, TA) enabled wine production from each of the experimental combinations tested. These approaches may be useful in organic farming programs in cold climates. Although they may reduce total yields, they also reduce the number of grapes unsuitable for vinification.
