Tips to Plant Coconut Saplings properly

Introduction

The coconut palm (Cocos nucifera linn.) is the most useful palm in the world. Every part of the tree is useful to human life for some purpose or the other. Hence, the coconut palm is endearingly called ‘kalpavriksha’ meaning the tree of heaven. The copra obtained by drying the kernel of coconut is the richest source of vegetable oil containing 65 to 70 per cent oil.

Climate and Soil

The coconut palm is found to grow under varying climatic and soil conditions. It is essentially a tropical plant growing mostly between 20oN 20oS latitudes. However, a rainfall of about 2000 mm per year, well distributed throughout, is ideal for proper growth and maximum production.

Coconut is grown under different soil types such as loamy, laterite, coastal sandy, alluvial, clayey and reclaimed soils of the marshy low lands. The ideal soil conditions for better growth and performance of the palm are proper drainage, good water-holding capacity, presence of water table within 3m and absence of rock or any hard substratum within 2m of the surface.

Varieties

There are only two distinct varieties of coconut, the tall and the dwarf.

The tall cultivars that are extensively grown are the West Coast Tall and East Coast Tall. The dwarf variety is shorter in stature and its life span is short as compared to the tall. Tall x Dwarf (TxD), Dwarf x Tall (DxT) are the two important hybrids.

There are 10 different combination of hybrids, developed by Kerala Agriculture University and Tamil Nadu Agriculture University and released for commercial cultivation. They are high yielders under the good management conditions. Laccadive Ordinary, Andaman Ordinary, Philippines, Java, Cochin-China, Kappadam etc. are the other tall cultivars under cultivation.

Planting Material

Coconut is propagated through seedlings raised from selected seednuts. Generally 9 to 12 month old seedlings are used for planting. Select seedlings, which have 6-8 leaves and 10-12 cm collar girth when they are 9-12 month old. Early splitting of leaves is another criteria in the selection of coconut seedling.

Site Selection

Shallow soils with underlying hard rock, low lying areas subject to water stagnation and clayey soils are to be avoided. Proper supply of moisture either through well distributed rainfall or through irrigation should be ensured before planting.

Preparation of Land and Planting

On slopes and in areas of undulating terrain, prepare the land by contour terracing or bunding. In low-lying areas mounds are to be formed at planting site to a height of at least 1m above water level. In reclaimed ‘kayal’ areas, seedlings are planted on field bunds.

In loamy soils with low water table, a pit size of 1mx1mx1m is recommended. In laterite soils with underlying rocks, take larger pits of size 1.2m x 1.2m x 1.2m. In sandy soils the size need not exceed 0.75m x 0.75m x 0.75 m.

Spacing and Systems of Planting

Spacing depends upon the planting system, soil type etc. In general the following spacing are recommended under different planting system in sandy and laterite soils.

Planting system Spacing
1 Triangular 7.6m
2 Square 7.6×7.6m, 8x8m, 9×9 m
3 Single 6.5m in rows – 9m between rows
4 Double Hedge 6.5 to 6.5m in rows – 9m between pairs of rows

Time of Planting

Seedlings can be transplanted in the beginning of the south west monsoon. If irrigation facilities are available, it is advisable to take up planting at least a month before the onset of the monsoon so that the seedlings get well established before heavy rains. Planting can also be taken up before the onset of the north-east monsoon. In low-lying areas subject to inundation during monsoon period, transplanting may be done after the cessation of the monsoon.

Planting

Before planting the pits are filled up with top soil and powdered cow dung / compost up to a depth of 50 to 60 cm. Then take a small pit inside this, so as to accommodate the nut attached to the seedling. Plant the seedling inside this pit and fill up with soil. Press the soil well so as to avoid water stagnation. If there is chance for white-ant attack apply Sevidol 8G(5gm.) inside the small pit before planting.

In laterite areas apply 2 kg common salt per pit for improving the physical condition of the soil. Burying 25 to 30 coconut husks per pit in layers will be useful for moisture conservation.
