Nutrient requirement

Tuberose reacts well to the application of organic and manures. Not only FYM (20 tonnes/ha) but also a fertilizer dose of 100 kg N, 50 kg P₂O₅ and 70 kg K₂O per hectare is suggested for tuberose production.

Foliar spray of ZnSO₄ 0.5% + FeSO₄ 0.2% + Boric acid 0.1% improves growth and flowering. For achieving increased essential oil content in flowers and for the maximum recovery of concrete, a fertilizer dose of 80 kg N, 60 kg P₂O₅ and 40 kg K₂O per hectare has been advised.

Passion fruit vines provide heavy food, which means they need plenty of fertilizer to ensure healthy growth during their growing season. A balanced 10-10-10 or similar all-purpose formula should be applied every three weeks. But, again, be careful when fertilizing because the fruit vines are susceptible to salt buildup in their soil. The nutritional requirements of the passion fruit depend on the age and stage of development, viz., Vegetative growth, plant coming in bearing, and total production stage. N 150, P 100, and K 200 kg/hectare is the approximate nutrient requirement of passion fruit. Nutrients should be distributed after harvesting.

Organic manures are essential for strong and productive plants with regular and maximum yields. Oil cake is also applied in some areas. 10 kg FYM per vine is recommended during the first year of planting and 15 kg FYM per vine from the second year. A mixture of FYM and vermicompost in the ratio of 4: 1 or 3: 1 and oil cake gives excellent results, but most farmers are not applying it due to the limited availability of vermicompost. Manure should be used in February-March. Nutrient management depends on the age and stage of growth of the vines. Organic manures should be added more for better fruit production. Keep the soil evenly moist to produce the best fruit. If the soil dries out, the fruit will shrink and drop. Passion fruit is a heavy feeder. Too much nitrogen will result in reduced leaf growth and fruit set.

The nutritional requirement of Peaches is higher compared to other stone fruits because it bears on one-year growth making the production of annual growth imperative for fruit production. Also, recoupment of the wood removal every year in pruning is necessary.

 Fertilizers are applied every year. A multitude of factors, including soil type, fertility, climate, cultivar, planting density, shoot growth, and irrigation, affect nutritional requirement and fertilizer application in peach orchards. The FYM (farmyard manure) along with a full dose of P and K must be applied during December and January. Half dose of Nitrogen is applied in spring before flowering and the remaining half dose a month later.

 Hibiscus plant needs lots of nutrients for good blooming. In the summer time, use a high potassium fertilizer. You can either use a diluted liquid fertilizer once a week, a slow-release fertilizer once a month or you can add high potassium compost to the soil. Supplementing the soil with garden compost or applying low phosphorous based fertilizer will result in high blooming. In winter, there is no need of fertilizing the plants.
