Abstract: To assess the agronomic effects of
sustainable okra production as impacted by goat manure (GM) and
rice husk ash (RHA) on a community-based demonstration farm in
Gombe State, field trials were carried out during the wet seasons
of 2017 and 2018. The trails consisted of four levels of GM and
RHA, each measuring 0.0, 5.0, 7.5, and 10.0 t ha-1
which were used on Kwadon's local cultivar of okra in a Randomized
complete block design (RCBD) replicated four times. Findings revealed
that days to 50% emergence and establishment count were not significantly
(P>0.05) influenced by the application of GM and RHA, regardless
of rates of application. Other growth-related indices were significantly
(P<0.05) higher due to GM, such as plant height at 4, 5, and
6 WAS, number of leaves plant-1 at 4 WAS, and pod diameter.
On the other hand, RHA significantly (P<0.05) increased plant
height, the number of leaves plant-1 at 5 and 6 WAS,
leaf area, shortened days to 50% flowering, and the number of
pods plant-1 across the sampling periods and seasons.
Similar to this, due to adequate mineralization of organic material
through time and space, fresh okra's marketable weight increased
in the 2018 season compared to the previous year. Thus, the application
of 10.0 t ha-1 of both GM and RHA can be adopted in
the production of okra in the study area to reduce greenhouse
gas emissions resulting from the use of inorganic agrochemical
inputs.
