The
following remedial measures can be followed to effectively manage this
problem:-
Rectification
of soil pH-Excess acidity or alkalinity of soil may
cause button shedding. If the soil pH is less than 5.5, the soil is too
acidic. This could be overcome by adding lime. High alkalinity is indicated
by soil pH higher than 8.0. This situation could be managed by adding gypsum.
Lack of nutrition-Button
shedding can occur as a result of inadequate manuring. The recommended dose
of manurial schedules and proper time of application are important to
minimise the button shedding. Soil application of 1.3 Kg urea, 2 Kg of Single
Super Phosphate and 2 Kg of potash, mixed with 50 Kg of farmyard manure per
palm. This can be followed by root feeding of Coconut tonic @ 40 ml in 160 ml
of water per palm once in 6 months which will control the button shedding and
enhance the yield.
Irrigation management- Button
shedding will be severe during March-April. Severe drought and / or
insufficient irrigation aggravate the problem. Soil mulching with green
fronds reduces evapo-transpiration and conserves soil moisture. Ensuring
sufficient irrigation during summer and drainage during winter will lead to a
sustainable yield.
Hormone deficiency- Apply 0.5 ml
of NAA (Planofix) mixed in 1 litre of water on the inflorescence. This
prevents button shedding.
Pests and Diseases- When young
buttons are formed sucking pests start infesting which in turn attracts secondary
fungal infections. Apply the recommended plant protection measures to ward
off the problem.
Boron deficiency or crown chokes disorder: Apply 200g of
borax/palm/year in two splits.
