Performance and quality attributes of okra (Abelmoschus esculentus (L.) Moench) fruits grown under soil applied Zn-fertilizer, green biomass and poultry manure.

Field experiments were carried out in 2018 and 2019 cropping seasons at Landmark University Teaching and Research farm, Omu-Aran Kwara state, Nigeria, to determine the effect of soil applied Zn-fertilizer, Tithonia diversifolia (Ti), Chromolaena odorata (Ch) and poultry manure (PM) on the performance, yield, minerals and vitamins composition of okra fruits. Treatments were combined and tested as follows:-Control (T), Control + 10 kg ha Zn (T), 5 t ha Ti + 5 t ha PM (T), 5 t ha Ch + 5 t ha PM (T), 5 t ha Ch + 5 t ha Ti (T), 10 t ha Ti + 0 kg ha Zn (T), 10 t ha Ti + 10 kg ha Zn (T), 10 t ha Ch + 0 kg ha Zn (T), 10 t ha Ch + 10 kg ha Zn (T), 10 t ha PM + 0 kg ha Zn (T), and 10 t ha PM + 10 kg ha Zn (T). The experiment was laid out in a randomized complete block design with four repetitions.
