Abstract:
A field experiment was conducted to evaluate the effects of biotic potassium on the growth and yield of okra.Significant effects were found,especially when biotic potassium was applied.The results showed that with the application of biotic potassium 4.5 g?m-2,the greatest plant height,as well as root shoot ratio,pod length,pod weight,pod number and okra yield were obtained.The fresh weight was the highest when the potassium was 7.5 g?m-2.There was no significant difference between it and 4.5 g?m-2.Change trends first increased and then decreased.The stem diameter and commodity rate of okra continued to increase with the increase of fertilizer,while root-shoot ratio on the contrary.The amount of biotic potassium had little effect on the dry-weight of pod,but had effect on stem diameter and root length and dry matter content of pod.The aim of the experiment was to achieve the field planting of okra best biological bacteria fertilizer amounts.Comprehensive all indicators,the optimum fertilization amount for field planting of okra was 4.5 g?m-2.
