Non-Composted Chinaberry (Melia azedarach L.) Sawdust Mixtures as Growth Medium for Okra (Abelmoschus esculentus (L.) Moench)

Sawdust as a soilless growth substrate for plants is becoming popular in greenhouse production. However, fresh sawdust often requires time decomposition before it ready use substrate. We studied whether amendments of banana peels (as source potassium), eggshells calcium), and urea nitrogen) non-composted chinaberry (Melia azedarach) could enhance its potential medium. In two pot experiments, the okra (Abelmoschus esculentus (L.) Moench) was evaluated using mixtures M. azedarach sawdust. The treatments were: (T1) 100% soil (control) (vol/vol); (T2) (T3) 80% +20% peel (T4) 60% eggshell (T5) (vol/vol) +91 kg N ha−1 (urea). There no significant difference between regarding seed germination emergence, but leaf area, chlorophyll content index, plant biomass, number pods per plant−1, pods, dry weight were significantly lower pots with mixtures. Organic improved Adding further 91 hectare−1 insufficient to produce same yield non-fertilized sandy clay loam soil. cannot exclude that may be okra, added not enough obtain yields when grown
