ABSTRACT
An experiment was conducted under All India Coordinated Research Project on palms at Horticultural Research Station, Ambajipeta to evaluate the yield performance of released coconut hybrids viz., Chandrasankara (COD x WCT), Lakshaganga (LCOT x GBGD), Keraganga (WCT x GBGD), Chandralaksha (LCOT x COD), VHC-I (ECT x MGD),VHC-II (ECT x MYD), Godavari Ganga (ECT x GBGD) and two varieties namely Chandrakalpa and Double Century. The experimental palms were planted during 2002 spaced at 7.5 x 7.5 m. in RBD with 3 replications maintaining 6 palms per replication and evaluated for 15 years. The results revealed that the coconut hybrid Godavari Ganga was found precocious, and comes to flowering within 45 months after planting followed by Lakshaganga and Chandralaksha (47 months). Significantly the highest nut yield of 135.1/palm/year and copra out put (26.5 kg/palm/year) was recorded with Godavari Ganga which was followed by Kera Ganga (120.6 nuts/palm/year) and Lakshaganga (118.3 nuts/palm/year). Significantly the highest oil content of 70.3% was recorded with VHC – II which was on par with Godavari Ganga (66%). However, the highest estimated oil yield (17.5 kg/ palm) was recorded with Godavari Ganga followed by VHC-II(16.0kg/palm)., Based on its superior performance with respect to higher nut yield, copra out put and oil yield, the coconut hybrid Godavari Ganga was found most suitable for cultivation in East coast region of Andhra Pradesh.
Key words: Coconut, Hybrid, Nut yield, Copra out turn, Tender nut water.
