Four treatments were represented by turfgrass seedlings evaluation at 30, 45, 60, and 75 days after sowing (DAS), between March and May, 2007. Replications included ten sample points by period, randomly selected with the aid of hollow squares (0.25 m&sup2;). Results indicated medium increment for dry matter in the aerial part of plants (67.4%, 73.8%, and 34.3%, respectively, at 45, 60, and 75 DAS). In relation to the number of leaves per plant, medium increment was verified for new leaves (3.6, 9.6, and 6.9, respectively, at 45, 60, and 75 DAS), as well as the appearance of a new tiller in turfgrass plants, every 15 days, from 30 to 75 DAS.</span></span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="en-US" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">KEY-WORDS: Growth;<strong> </strong>Bahiagrass; seedlings.</span></span></span></p><p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">A fim de avaliar o desenvolvimento inicial de gramado semeado com a esp&eacute;cie <em>P. notatum</em>, rec&eacute;m-instalado por meio de semeadura, um experimento foi conduzido em &aacute;rea destinada &agrave; forma&ccedil;&atilde;o de um campo de futebol. A semeadura foi realizada a lan&ccedil;o, em 2.400 m<sup>2</sup>, utilizando-se 50 kg de sementes. Quatro tratamentos foram representados pela avalia&ccedil;&atilde;o das pl&acirc;ntulas do gramado, aos 30, 45, 60 e 75 dias ap&oacute;s a semeadura (DAS), entre mar&ccedil;o e maio de 2007. As repeti&ccedil;&otilde;es foram dez pontos amostrais por &eacute;poca, escolhidos aleatoriamente, com aux&iacute;lio de quadrados vazados (0,25 m&sup2;). Os resultados indicaram ter havido incremento m&eacute;dio da mat&eacute;ria seca na parte a&eacute;rea das plantas de 67,4%; 73,8%; e 34,3%, respectivamente, aos 45, 60 e 75 DAS. Com rela&ccedil;&atilde;o ao n&uacute;mero de folhas por planta, foi constatado incremento m&eacute;dio de novas folhas de 3,6; 9,6; e 6,9, respectivamente, aos 45, 60 e 75 DAS, assim como o surgimento de novo afilho nas plantas do gramado, a cada 15 dias, entre 30 e 75 DAS.</span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">PALAVRAS-CHAVE:<strong> </strong>Crescimento; grama batatais; pl&acirc;ntulas.</span></span></span></p>
