Performance of okra (Abelmoschus esculentus (L.) Moench) as influenced by organic fertilizer rates
Main Article Content
Abstract
A two year field study was conducted during the late cropping season from September to December 2016 and 2017, to evaluate the response of two okra varieties (Clemson spineless and a local cultivar) to five rates of Pure organic fertilizer TM (0, 1, 2, 3, 4 t ha-1and NPK 20.10.10 at 120 kg ha-1 as check) using a 2 x 6 factorial experiment in randomized complete block design having three replications. Data was collected for agronomic traits as well as yield performance. Analysis of variance was done using GENSTAT Package version 8.1 and means were compared using Duncan’s New Multiple Range Test at 5 % probability level. The results obtained from this study showed that organic fertilizer at 4 t ha-1 resulted in significantly higher (p<0.05) okra yields of 5.12 and 2.84 t ha-1 respectively in 2016 and 2017, compared to all other treatment levels. The varietal effect was not significant while some of the interactions were highly significant. Pure organic fertilizer at 4.0 t ha-1 is suitable for okra production.
