Abstract

This study hypothesized that biochar produced from different feedstock contains varied nutrient compositions and may ameliorate acidic soil and improve yield parameters of cucumber ( Cucumis sativus ) via an interrelated structure. We aimed to evaluate biochar nutrient composition from different feedstock and inspect the interrelationship between soil pH and yield parameters of cucumber using structural equation modeling (SEM). Eleven treatments consisting of the sole application of biochar (B) from different feedstocks at the rate of 20 t ha−1 and their combinations with poultry manure (i.e., 10 t ha−1 biochar +10 t ha−1 poultry manure) were used. The highest pH value of 5.89 was obtained in fields amended with 20 t ha−1 plantain peel biochar (PPB). We used SEM to find that soil pH produced a negative but significant relationship with fruit weight and length. Combining biochar with poultry manure is recommended for sustainable cucumber production in the tropical region of Nigeria or elsewhere.

生物炭处理对土壤 pH 值和黄瓜果实的影响：证明生物炭对尼日利亚热带土壤的重要性

本研究假设，由不同原料生产的生物炭含有不同的营养成分，可通过相互关联的结构改善酸性土壤并提高黄瓜（Cucumis sativus）的产量参数。我们的目的是评估来自不同原料的生物炭养分成分，并利用结构方程建模（SEM）研究土壤 pH 值与黄瓜产量参数之间的相互关系。我们采用了 11 个处理，包括单独施用不同原料的生物炭（B）（施用量为 20 吨/公顷-1）及其与家禽粪便的组合（即 10 吨/公顷-1 生物炭 +10 吨/公顷-1 家禽粪便）。使用 20 吨/公顷-1 的车前草皮生物炭（PPB）改良的田块 pH 值最高，为 5.89。我们利用扫描电镜发现，土壤 pH 值与果实重量和长度呈负相关，但关系显著。建议在尼日利亚热带地区或其他地方将生物炭与家禽粪便相结合，以实现黄瓜的可持续生产。
