Coconut
Fertilizers and micronutrients greatly contribute to the growth and yield of coconut. We will look at the deficiencies of each nutrient found in coconut and its remedies
Nitrogen
Promotes the growth of the coconut tree. Plays a major role in the production of female flowers. Its deficiency affects the growth of the coconut tree and the young and mature leaves turn yellow. The size of the 14th leaf in coconut should be 1.8-2.0 percent.
Potash
The base of the coconut tree is used for thickening. Its deficiency in the soil affects the growth of roots. Further flowering and maturation of the coconut are delayed. Coconut leaves should contain 0.12 percent humus.
phosphorus:
Coconut is widely used to make lentils and oils. It also helps in capturing more pods and making the lentils thicker. The ash gives the tree resistance to pests. Its deficiency is characterized by orange spots on the leaf or small pale yellow spots that can penetrate light. As the ash deficiency increases, the leaves of the tree appear shriveled and stunted.
Calcium:
Helps greatly in the growth of stems and leaves. Its deficiency is not usually found in tall coconut varieties. But the short-lived coconut trees are lacking. The size of 0.30.-0.40 percent of the 14th leaf in coconut is optimal for growth. This requirement can be met by applying calcium-containing fertilizers such as superphosphate and rock phosphate to the coconut tree.
Magnesium:
Short coconut varieties are more likely to show signs of magnesium deficiency than tall varieties. The lower leaves turn yellow due to deficiency. 0.24% magnesium is required in the 14th leaf of coconut for tree growth. For magnesium deficiency, 500 g of magnesium sulfate per tree per year is required. Divide evenly and apply at the rate of 250 gm for six months.
Sulfur:
Deficiency is seen in coconut when the level of sulfur in coconut leaf is below 0.12%. Therefore, its optimum range of 0.12 to 0.19 percent is suitable for tree growth. The leaves turn pale yellow. Also, the density of the lentils decreases and does not become solid.
Zinc:
Due to its deficiency, the leaves of the coconut appear small and deformed. To avoid this deficiency, apply 500 g of zinc sulfate per tree per year.
Boron:
Boron greatly aids in the production and germination of pollen. Its deficiency affects the tissue growth of the tree. The leaves also stop growing longer and the tips of the leaves bend and appear in a "V" shape. The young leaves on the tree are unbroken. The coconuts fall down before they mature. Boron from 10 to 13 ppm in the 14th leaf is ideal for coconut growth. 200 g of borax per tree should be applied to remove the deficiency.
Manure and composting:
For tall coconut, apply 1.2 kg urea, 2 kg superphosphate, 2 kg muriate of potash fertilizer, 50 kg manure, and 1 kg neem per year. The active grafted coconut should be treated with 2.25 kg urea, 1.5 kg superphosphate, 3.00 kg muriate of potash 50 kg manure, and 2 kg neem paste per year. Apply 1/4 share of the above fertilizer in the first year, 1/2 share in the second year, and 3/4 share in the third-year-old calves. Divide the total amount of fertilizer evenly and apply in August and March. Apply fertilizer and chemical fertilizers on the surface of the 6 feet radius bed taken around the tree, cover with a spade, and then water. Apply coconut micronutrient mixture at the rate of 1 kg per tree per year.
Or 200 ml of coconut tonic should be applied to the roots of a tree once in 6 months. Doing so will control the naughty shedding and increase the yield. Sow 100 g of hemp in a circle and harvest at the time of flowering and place in a circle. Doing this three times a year does not require 50 kg of manure per tree alone. Doing so will control the shedding and increase the yield.
Fertilizing method for coconut
In the first year after the loss of coconut, 500 g of urea, 500 g of superphosphate, 825 g of potash, 1250 g of neem paste and 10 kg of FYM should be applied. In the second year urea 1300 g, superphosphate 800 g, potash 1625 g, neem Two and a half kg of booze, 2 kg of manure, 1600 g of urea, 1200 g of superphosphate, 2 and a half kg of potash, 3 kg 750 g of neem cake, 3 kg of manure, 2 kg of urea, 1 kg 600 g of superphosphate, 3 kg of potash 300 kg. Apply 5 kg of neem paste and 4 kg of manure.
For coconuts older than four years, 2 kg urea, 1 kg 600 g superphosphate, 3 kg 300 g potash, 5 kg neem paste, and 5 kg manure should be applied. Especially These fertilizers should be applied one half in July, one half in August, and the other half in October.
