ABSTRACT:

The paper investigated the effect of Mulching, Organic and Inorganic Fertilizers on the Rhizome yield of Ginger (Zingiber Officinale) in Abuja, Nigeria. Field trials were carried out in the 2019 cropping season at the University of Abuja Teaching and Research Farm, main campus Gwagwalada. The experiment contained 7 treatments laid out in a randomized complete block design (RCBD) and replicated three times. The results showed that the plots treated with mulching had the highest ginger plant height at 2WAP (23.30a) and 3WAP (28.91a) while control (19.67b) had the lowest plant height. The plots treated with mulching had the highest number of ginger leaves at 2WAP (8.67a) and 3WAP (11.33a) and control (8.00bc) had the lowest number of leaves at 3 WAP. Stem diameter was significantly higher in soils treated with mulching at 2 WAP (1.240a) while the application of the different fertilizers did not have any significant effect on the stem diameter at 3 WAP. The plots treated with mulching and its combinations gave the highest number of tillers at 2 WAP while the control plots gave the least number of tillers at both 2 WAP (1.00b) and 3 WAP (1.000c). Rhizome fresh weight was highest in soils treated with NPK + mulching (23.69a) and lowest (10.17d) in the control plots while the Rhizome dry weight was highest in soils treated with NPK + mulching (16.58a) and lowest (7.12d) in the control plots. It is therefore concluded that mulching is imperative for the successful production of ginger in Abuja, Nigeria.
