Investigations were carried out to study the impact of inorganic fertilizer substitutions by vermicompost on productivity of coconut during 2001 to 2009 at CPCRI, RS, Vittal in a 22 year old coconut garden under laterite soil. The treatments viz. recommended inorganic fertilizer (500g N, 320g P2O5 and 1200g K2O palm/year), 25 % of N in the form of Vermicompost (VC) (9.6 kg/palm)+75 % of NPK, 50 % N in the form of Vermicompost VC (19.2 kg/palm)+50 % of NPK, 75 % N in the form of Vermicompost (VC) (28.8 kg/palm)+25 % NPK and 100 % N in the form of VC alone (38.5 kg/palm) were imposed in randomized block design. Five year pooled nut yield data indicated that, application of vermicompost in combination with inorganic fertilizer either at 25 % Vermicompost (VC) + 75 % NPK (65 nuts) or 50 % VC + 50 % NPK (63.2 nuts) resulted in significantly higher nut yield. The copra content and oil content did not differ significantly among the treatments. However, the copra content was ranged between 182.2 g to 184.4 g/nut and oil content ranged between 64.0 to 65.8 %. Economics of different treatments indicated that, the net return obtained under 25 % Vermicompost (VC) + 75 % NPK and 50 % VC + 50 % NPK was higher (Rs. 16,673/- and Rs. 16,144/-per ha, respectively) compared to other treatments.
