Coconut mannuring
Dear sir,
U have not mentioned the age of the tree but from yr statement it appears that it was not properly managed orchard and more coconut manure will show its effects only after 3 years of application so test yr soil fallow the this method.
Manuring
Regular manuring from the first year of planting is essential to achieve higher productivity. For coconut 20 - 50kg. organic manure should be applied per palm per year with the onset of south west monsoon, when soil moisture content is high. Different forms of organic manures like compost, farm yard manure, bone meal, fish meal, blood meal, neem cake, groundnut cake etc. could be made use for this purpose. In addition to this the following Fertilizer Schedule is recommended.
The fertiliser schedule recommended for the palm at different stages is as follows:-
Quantity of fertilizer to be applied (gm)
Age of Palm Nutrient dosage Ammo. Sulphate Urea Super Phosphate (single) or Ultraphos/ Rock Phosphate Muriate of Potash
1. General recommendation:
(a) Average Management:
3 months 1/10 of full dose 165 75 95 60 115
1 year 1/3 of full dose 550 250 320 200 380
2 year 2/3 of full dose 1100 500 640 400 760
3 year onwards full dose 1650 750 950 600 1140
(b) Good management:
3 months 1/10 of full dose 250 110 180 115 200
1 year 1/3 of full dose 800 360 590 380 670
2 year 2/3 of full dose 1675 720 1180 760 1340
3 year onwards full dose 2000 1080 1780 1140 2010
2. Hybrid and high yielding palms:
a. Under Irrigated condition:
3 months 1/10 of full dose 490 220 280 180 335
1 year 1/3 of full dose 1625 720 930 600 1110
2 year 2/3 of full dose 3250 1450 1850 1200 2220
3 year onwards full dose 4880 2170 2780 1800 3330
(b) Under rainfed condition:
Same as that of good management under general recommendation.
The full adult doze recommended for the rainfed tall is 0.34kg N, 0.17kg P and 0.68kg K. For the hybrids and irrigated talls the general recommendation is 0.5kg N, 0.34kg P and 1.0kg. K subject to changes in accordance with soil test and/or foliar analysis data.
In addition to the above dose of fertilizers two to three kgs. of finally ground dolomite lime stone or 0.5 kg. Magnesium sulphate per palm per year is also recommended for use in acidic soils, light sandy soils and in root wilt affected tracts in Kerala. The dolomite may be broadcasted prior to the onset of monsoon in the basins and forked in and should not be applied along with other fertilizers. There is however no harm in applying magnesium sulphate along with other fertilizers.
