Kiwi is a high-value fruit crop that is gaining popularity in India, especially in hilly and temperate regions. To get good vine growth, regular flowering, and quality fruit, proper fertilizer management is very important. Many farmers face problems like weak vine growth, poor flowering, or small fruits due to incorrect or irregular fertilizer application. Understanding the recommended fertilizer dose and applying it at the right time helps maintain healthy kiwi plants and improves yield.
Kiwi plants require balanced nutrition throughout the year because they are vigorous climbers and heavy feeders. The main nutrients required are nitrogen, phosphorus, and potassium, along with organic matter and micronutrients. Fertilizer requirement mainly depends on the age of the plant, soil fertility, and production stage.
For young kiwi plants in the first one to two years, the focus should be on vegetative growth and root development. During this stage, a lower fertilizer dose is sufficient. Organic manure such as well-decomposed farmyard manure or compost should be applied every year. This improves soil structure and supports steady growth. Along with organic manure, a small quantity of nitrogen, phosphorus, and potassium can be applied to support healthy vine development. Fertilizers should be applied in split doses to avoid root damage.
For kiwi plants aged three to four years, fertilizer dose should be increased gradually as the plant size and nutrient demand increase. Nitrogen helps in vine growth and leaf development, phosphorus supports root strength and flowering, and potassium is important for fruit development and overall plant health. At this stage, fertilizers are usually applied in two split doses—one before the start of active growth in spring and another after flowering.
For fully grown and bearing kiwi plants, regular and balanced fertilizer application is essential. A good quantity of organic manure should be applied once a year, preferably during winter or early spring. Along with this, recommended doses of nitrogen, phosphorus, and potassium are applied in split doses. Nitrogen should not be applied all at once, as excess nitrogen leads to excessive vegetative growth and poor fruiting. Splitting nitrogen improves uptake and reduces nutrient loss.
Potassium is especially important for kiwi plants during flowering and fruit development stages. Adequate potassium helps improve fruit size, taste, and shelf life. Phosphorus supports strong root systems and helps in better flowering and fruit setting.
Micronutrients also play an important role in kiwi nutrition. Deficiency of elements like boron, zinc, iron, and magnesium can lead to poor flowering, leaf yellowing, fruit drop, and reduced yield. If deficiency symptoms are noticed, foliar sprays of micronutrients help correct the problem quickly.
Fertilizers should be applied around the root zone, not too close to the trunk. Light incorporation into soil and irrigation after fertilizer application help nutrients reach the roots effectively. Kiwi plants require adequate soil moisture for proper nutrient uptake, so fertilizer application should be done when the soil is moist.
Mulching around the plant basin helps conserve moisture, improve soil fertility, and enhance fertilizer efficiency. Mulch also protects roots from temperature fluctuations.
Soil testing is highly recommended before finalizing fertilizer dose. Soil test results help farmers adjust fertilizer quantity based on actual nutrient status and avoid overuse.
In conclusion, the recommended fertilizer dose for kiwi plants depends on plant age and growth stage. Regular application of organic manure, balanced use of nitrogen, phosphorus, and potassium, attention to micronutrients, and proper irrigation together ensure healthy growth and good fruit yield. With proper nutrient management, kiwi farmers can achieve better productivity and long-term orchard health.
