FERTILIZER EFFECTS ON THE GROWTH AND YIELD OF GINGER (Zingiber officinale Roscoe) IN CROSS RIVER STATE, NIGERIA by Attoe, E. E., Undie U. L. & Kekong, M. A.

 Abstract

Field experiments were conducted in two locations, Akamkpa and Obubra both in Cross River State, Nigeria in 2006 and 2007 to evaluate the effects of different levels of NPK fertilizer on growth parameters and yield of ginger (Zingiber officinale Roscoe). The experiment was laid out into a split plot design with three replications. Eighteen different combinations were evaluated. The three major nutrients N, P and K were investigated at the rate of 0, ½ , 1, 1½ and 2 times, the recommended base rates of 200kg/ha N, 80kg/ha P205 and 100kg/ha K20. The plant parameters accessed included plant height, number of leaves, number of shoots, leaf area, fresh weight of plants and fresh rhizome yield was measured. Results showed that ginger performed better in Obubra in terms of growth parameters and rhizome yield. The average fresh rhizome yield of 8.10 tons per hectare was 21% higher than the yield at Akamkpa. The study also confirmed that the optimum NPK treatment combination of 200:80:100kg/ha gave the best rhizome yield during the trials.

KEY WORDS: Soil Properties, NPK Fertilizers, Growth and Yield of Ginger.
