Resumo: | The association between biochar and green manure in the papaya crop may be a promising management technique, mainly in its first growth stage. This study aimed to evaluate the effects of biochar and green manure (Mucuna aterrina) on the growth and nutrition of Carica papaya seedlings, as well as on soil fertility. The experiment followed a randomized block design (5 blocks), in a 2 x 2 factorial arrangement: with and without mucuna and with and without biochar. The biochar or mucuna application significantly increased the papaya plant shoot and root growth, as well as the chemical features of the soil, whereas their joint application did not provide synergistic effects, except for the leaf P concentration. The application of biochar and biochar + mucuna enabled a fast initial increase in plant height. However, it also showed a visible N deficiency, despite the increased N, P, K, Ca and Mg accumulation and use efficiency in the plants. The effect of the biochar/mucuna joint application is synergistic for the leaf P content and plant height. The individual or joint application of biochar and mucuna increases the papaya plant growth and nutrition and maintains the soil fertility. KEYWORDS: Carica papaya L., Mucuna aterrina, green manure. |

KEYWORDS: Carica papaya L., Mucuna aterrina, green manure.A associação de biochar a adubos verdes no cultivo de mamoeiro pode ser uma técnica de manejo promissora, principalmente em sua primeira fase de cultivo. Objetivou-se avaliar os efeitos de biochar e adubo verde (Mucuna aterrina) no crescimento e nutrição de mudas de Carica Papaya e na fertilidade do solo. O experimento foi conduzido em blocos casualizados (5 blocos), em esquema fatorial 2 x 2: presença e ausência de mucuna e presença e ausência de biochar. No crescimento da parte aérea e das raízes do mamoeiro, e também nas características químicas do solo, a aplicação de biochar ou mucuna resultou em incrementos significativos, enquanto a aplicação conjunta não proporcionou efeitos sinergísticos, exceto para o teor foliar de P. A aplicação de biochar e de biochar + adubo verde proporcionou rápido crescimento inicial em altura das plantas. No entanto, apresentou, também, deficiência visível de N, apesar dos maiores conteúdos e eficiência de utilização de N, P, K, Ca e Mg nas plantas. O efeito da aplicação conjunta de biochar e mucuna é sinérgico para o teor foliar de P e altura das plantas. A aplicação individual ou em conjunto de biochar e mucuna aumenta o crescimento e nutrição de plantas de mamão e mantém a fertilidade do solo.
