This document provides nutrient management recommendations for black pepper vines. It recommends applying 10 kg of organic manure per vine annually in May. It also recommends applying lime at 600g per vine every other year to increase soil pH and nutrient availability. Specific fertilizer recommendations are also provided, including applying 100g of N, 40g of P, and 140g of K per vine in split doses in May-June and September-October. Slaked lime at 500g per vine is recommended every other year in May-June. Manure and fertilizers should be applied around vines 30cm from the base.

3. • Application of manure.
At least 10kg of organic manure in the form of FYM/green
leaves/compost/well rotten cattle/poultry manure should
be given per vine per annum during the month of May i.e.
at the onset of South West monsoon.
• These may be applied in shallow basins taken around the
plants which are to be covered with a thin layer of soil
after the application of manure..
• Application of lime at the rate of 600g per vine during
April- May in alternate years should be done to increase
the soil pH, availability of nutrients and to reduce the
aluminium toxicity in soil.

4.  Apply cattle manure or Compost @ 10 kg/vine just before the
onset of South West monsoon.
 In addition 100 g of N, 40 g of P and 140 g of K per vine are
applied in two split doses in the months of May - June and
in September - October.
 Slaked lime at 500 g per vine is applied in alternate years
during May - June.
 The manures and fertilizers are applied around the vine at
a distance of 30 cm from the base and incorporated into
the soil.
 Azospirillum @ 100 g/vine can be applied one month after
the application of chemical fertilizers.
Manuring:

5.  Manuring and fertilizer application is critical for proper
establishment and growth of plants.
 Organic manures in the form of cattle manure or compost can
be given @ 10 kg/vine during May.
 Neem cake @ 1 kg/vine can also be applied.
 Recommended blanket nutrient dosage for black pepper vines
(3 years and above) are as follows:
 NPK 50: 50: 150 g/vine/year (General recommendation)
 NPK 50: 50: 200 g/vine/year (for Panniyur and Kannur district in
Kerala)
 NPK 140: 55: 270 g/vine/year (for Kozhikode district in Kerala).

6. For main field
Any of the following formulation can be drenched in the soil twice (May – June and
October - November).
Neem cake 1/2 kg per vine + Swabbing of Bordeaux paste upto 1 m from the ground
level.
Trichoderma viride @ 20 g/vine + FYM or Bordeaux mixture 1 % or Metalaxyl-
Mancozeb @ 2 g/lit.
Neem cake 2 kg per vine + 0.1% Metalaxyl (pre monsoon foliar spray and soil
application).
Pseudomonas fluorescens (50 g) (pre and post monsoon) + neem cake (2 kg) (post
monsoon) + metalaxyl 0.1 %.

7. Fruit drop
The spike shedding can be reduced by
foliar spray of Diammonium Phosphate
1.0 % four times viz., before flower
initiation (May), during new leaves and
flower emergence (June) before spike
initiation (July) and pinhead stage of
berries (August).
