Autumn cucumbers require careful selection of varieties that are heat-tolerant, disease-resistant, vigorous, and high-yielding. It's important not to sow them too late, as the cooler temperatures later in the season can negatively affect fruit development and overall yield.
During the growth period, autumn cucumbers experience both vegetative and reproductive growth simultaneously. This means they grow quickly, have a short growing cycle, and require a significant amount of nutrients. Fertilization should follow the principle of "light base fertilizer, heavy fruit fertilizer" and "small, frequent feedings with compost." Typically, a base application of organic manure is recommended—around 1,500 kg per acre, along with 50 kg of compound fertilizer or a mix of 50 kg compound fertilizer and 25 kg ammonium bicarbonate.
After transplanting, a diluted solution of human urine and feces (1:10) can be used as seedling fertilizer, applied once a week. As the plants grow, regular top-dressing should be done, and trellises or supports should be set up. During the fruiting stage, the frequency of fertilization should increase, and it’s ideal to apply fertilizer after each harvest. On rainy days, 5–7.5 kg of urea per acre can be sprinkled, and during the fruiting phase, foliar sprays of 0.3% potassium dihydrogen phosphate or 3% urea can be used for additional nutrition.
Autumn cucumbers enjoy water but are also sensitive to overwatering. Improper irrigation can lead to diseases and reduce yields. Therefore, watering should be carefully managed based on weather conditions, soil type, and plant health. Watering is best done in the early morning or late afternoon when it's cooler, avoiding midday when temperatures are high. It's recommended to use furrow irrigation, with small, frequent waterings to keep the soil moist without causing waterlogging. Once the soil begins to dry out, it's time to apply fertilizer and maintain consistent moisture levels.
