&lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span&gt;&lt;span style="font-size: x-small;"&gt;&lt;span style="font-size: small;"&gt;Physic nut species has shown great potential for biofuel production. This study aimed to evaluate the effect of inoculation with the arbuscular mycorrhizal fungus &lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;em&gt;Glomus clarum&lt;/em&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt; and the application of organic compost on the growth and phosphorus (P) and nitrogen (N) &lt;/span&gt;&lt;span style="font-size: small;"&gt;absorption,&lt;/span&gt;&lt;span style="font-size: small;"&gt; in physic nut seedlings. A randomized experimental blocks design, in a 5x2 factorial scheme, was used, with the evaluation of organic compost levels (0 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, 15 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, 30 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, 60 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, and 120 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;) and presence or absence of &lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;em&gt;Glomus clarum&lt;/em&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt;, with four replications. Physic nut seedlings inoculated with &lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;em&gt;Glomus clarum&lt;/em&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt; presented, at levels of 15 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1 &lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;of organic compost, the lowest height (20%), 120 days after sowing. However, the basal diameter increased, at levels of 30 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; (21%) and 120 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; (33%) of organic compost, 60 days after sowing. Only in the treatment with &lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;em&gt;Glomus clarum&lt;/em&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt;, physic nut seedlings showed increasing linear regression adjustment in the dry matter of stem (R&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;2&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; = 0.99), aerial part (R&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;2&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; = 0.98), roots (R&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;2&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; = 0.95), and whole plant (R&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;2&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; = 0.97), depending on the organic compost levels. Physic nut seedlings inoculated with &lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;em&gt;Glomus clarum&lt;/em&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt; showed increases in P content of the aerial part of 93%, 37%, 57%, and 51%, for levels of 15 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, 30 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, 60 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt;, and 120 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; of organic compost, respectively. For the N content, such increases were 50% and 45%, at levels of 0 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; and 60 t ha&lt;/span&gt;&lt;sup&gt;&lt;span style="font-size: small;"&gt;-1&lt;/span&gt;&lt;/sup&gt;&lt;span style="font-size: small;"&gt; of organic compost, respectively.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span&gt;&lt;span style="font-size: small;"&gt;KEY-WORDS: &lt;em&gt;Jatropha curcas&lt;/em&gt; L.; biofuel; &lt;em&gt;Glomus clarum&lt;/em&gt;; seedlings quality.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;<br>&lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span&gt;&lt;span style="font-size: small;"&gt;A esp&amp;eacute;cie pinh&amp;atilde;o manso t&amp;ecirc;m se mostrado bastante promissora para a produ&amp;ccedil;&amp;atilde;o de biodiesel. O presente trabalho objetivou avaliar o efeito da inocula&amp;ccedil;&amp;atilde;o do fungo micorr&amp;iacute;zico arbuscular &lt;em&gt;Glomus clarum&lt;/em&gt; e da aplica&amp;ccedil;&amp;atilde;o de composto org&amp;acirc;nico sobre o crescimento e absor&amp;ccedil;&amp;atilde;o de f&amp;oacute;sforo (P) e nitrog&amp;ecirc;nio (N), em mudas de pinh&amp;atilde;o manso. Utilizou-se o delineamento experimental em blocos ao acaso, em esquema fatorial 5x2, sendo avaliados os fatores doses de composto org&amp;acirc;nico (0 t ha&lt;sup&gt;-1&lt;/sup&gt;, 15 t ha&lt;sup&gt;-1&lt;/sup&gt;, 30 t ha&lt;sup&gt;-1&lt;/sup&gt;, 60 t ha&lt;sup&gt;-1&lt;/sup&gt; e 120 t ha&lt;sup&gt;-1&lt;/sup&gt;) e presen&amp;ccedil;a ou aus&amp;ecirc;ncia do inoculante &lt;em&gt;Glomus clarum&lt;/em&gt;, com quatro repeti&amp;ccedil;&amp;otilde;es. As mudas de pinh&amp;atilde;o manso inoculadas com &lt;em&gt;Glomus clarum &lt;/em&gt;apresentaram, na dose de 15 t ha&lt;sup&gt;-1&lt;/sup&gt; de composto org&amp;acirc;nico, menor altura (20%), aos 120 dias ap&amp;oacute;s a semeadura. No entanto, o di&amp;acirc;metro, &amp;agrave; altura do colo, foi maior, nas doses de 30 t ha&lt;sup&gt;-1&lt;/sup&gt; (21%) e 120 t ha&lt;sup&gt;-1&lt;/sup&gt; (33%) de composto org&amp;acirc;nico, aos 60 dias ap&amp;oacute;s a semeadura. Apenas no tratamento com &lt;em&gt;Glomus Clarum&lt;/em&gt;, mudas de pinh&amp;atilde;o manso apresentaram ajuste de regress&amp;atilde;o linear crescente, na mat&amp;eacute;ria seca de caule (R&lt;sup&gt;2 &lt;/sup&gt;= 0,99), parte a&amp;eacute;rea (R&lt;sup&gt;2 &lt;/sup&gt;= 0,98), ra&amp;iacute;zes (R&lt;sup&gt;2 &lt;/sup&gt;= 0,95) e planta inteira (R&lt;sup&gt;2 &lt;/sup&gt;= 0,97), em fun&amp;ccedil;&amp;atilde;o das doses de composto org&amp;acirc;nico. Mudas de pinh&amp;atilde;o manso inoculadas com &lt;em&gt;Glomus clarum&lt;/em&gt; apresentaram incrementos nos teores de P da parte a&amp;eacute;rea de 93%, 37%, 57% e 51%, para as doses de 15 t ha&lt;sup&gt;-1&lt;/sup&gt;, 30 t ha&lt;sup&gt;-1&lt;/sup&gt;, 60 t ha&lt;sup&gt;-1&lt;/sup&gt; e 120 t ha&lt;sup&gt;-1&lt;/sup&gt; de composto org&amp;acirc;nico, respectivamente. Para os teores de N, tal incremento foi de 50% e 45%, nas doses de 0 t ha&lt;sup&gt;-1 &lt;/sup&gt;e 60 t ha&lt;sup&gt;-1&lt;/sup&gt; de composto org&amp;acirc;nico, respectivamente.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span&gt;&lt;span style="font-size: small;"&gt;PALAVRAS-CHAVE: &lt;em&gt;Jatropha curcas &lt;/em&gt;L.; biocombust&amp;iacute;vel; &lt;em&gt;Glomus clarum&lt;/em&gt;; qualidade de mudas.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
