Kiwi is becoming a popular fruit crop among farmers in India, especially in hilly and cooler regions. It grows well in areas with good rainfall, mild summers, and frost-free winters. To get healthy vines and high-quality fruits, proper nutrition management is very important. Many farmers face confusion about how much fertilizer to apply and at what stage of growth. Understanding the recommended fertilizer dose helps ensure strong vine growth, better flowering, and higher yield.
Kiwi is a vigorous climber and needs fertile, well-drained soil. Before planting, farmers should prepare the field properly. Farmyard manure (FYM) is very helpful for improving soil structure. Applying about 20–25 kg of well-decomposed FYM per planting pit during field preparation gives a good start to young plants. This organic manure releases nutrients slowly and increases soil moisture-holding capacity.
For chemical fertilizers, the nutrient needs of kiwi plants increase as they grow. Young vines require smaller quantities, while bearing vines need more for fruit production. Generally, the recommended fertilizer dose for a mature kiwi plant is around 600–800 grams of Nitrogen (N), 400–500 grams of Phosphorus (P₂O₅), and 800–1000 grams of Potassium (K₂O) per year. These quantities support overall plant health, root development, flowering, and fruit quality.
It is not advisable to apply the full fertilizer dose at one time. Kiwi vines respond better when the nutrients are given in split doses. The yearly fertilizer requirement can be divided into two or three applications. The first application is usually done just before new growth begins in early spring. This helps push new shoots and leaf formation. The second application is done at the time of fruit development, which supports healthy fruit size and reduces fruit drop. If needed, a third application can be given after harvest to help the plant recover and prepare for the next season.
Nitrogen should be used carefully, as excess nitrogen may cause excessive vegetative growth and reduce fruiting. Potassium is very important for improving fruit size, sweetness and storage quality. Phosphorus helps in root development and enhances flowering. Along with the main nutrients, kiwi plants also need micronutrients like zinc, boron, magnesium, and iron. If the leaves show yellowing or poor growth, farmers can apply micronutrient mixtures as foliar sprays two to three times in a season.
Mulching also plays a major role in kiwi nutrition. Applying dry leaves, grass, or straw mulch around the base of the plant helps conserve soil moisture, reduces weed growth, and slowly adds organic matter. Avoid piling mulch directly against the stem to prevent fungal problems.
Irrigation and fertilizer management should go hand in hand. Fertilizers work better when the soil has enough moisture. During dry periods, light irrigation after fertilizer application helps nutrients move into the root zone. Avoid waterlogging, as kiwi roots are sensitive to standing water.
With proper fertilizer application, kiwi plants grow stronger, produce healthy shoots, and give good-quality fruits year after year. Farmers who follow balanced nutrition practices often see better yields and longer productive life of their kiwi orchards. A combination of organic manure, balanced chemical fertilizers, and timely micronutrient sprays ensures the best performance of kiwi vines in Indian conditions.
