| English abstract | The objective of this work was to compare the growth of Prunus sellowii Koehne seedlings (pessegueirobravo), submitted to conventional fertilizations and to basalt dust as an alternative. The experiment was installed in January of 2004 in the Embrapa Florestas nursery (Colombo - PR), using medium tubes (100 cm³), and commercial substratum composed by Pinus husk and vermiculita. The experiment was carried out on a randomized block design, with the following treatments: without fertilization; mineral fertilization NPK; mineral fertilization NPK plus micronutrients; and basalt dust. They were evaluated the following characteristics: height, collar diameter, dry biomass (aerial and root) and leaves nutrients composition. The results had shown that seedlings growth was higher when fertilized with NPK, increased or not with micronutrients. Seedlings produced with basalt dust fertilization had not gotten similar growth to those ones without fertilization, however, in this treatment the biggest values of N, P, Ca, Mg, B, Fe and Mn in leaves had been observed |
| Portuguese abstract | Este trabalho objetivou comparar o crescimento de mudas de Prunus sellowii Koehne (pessegueirobravo), submetidas a adubações convencionais e, como alternativa, ao pó de basalto. O experimento foi instalado em janeiro de 2004 no viveiro da Embrapa Florestas (Colombo/PR), utilizando-se tubetes médios (100 cm³) e substrato comercial à base de casca de Pinus sp. e vermiculita. O delineamento foi em blocos ao acaso, nos seguintes tratamentos: sem adubação; adubação mineral NPK; adubação mineral NPK com micronutrientes; e pó de basalto. As variáveis analisadas foram altura, diâmetro de colo, biomassa seca (aérea e radicular) e análise de nutrientes foliares. Os resultados mostraram o melhor crescimento das mudas quando adubadas com NPK, acrescida ou não com micronutrientes. Mudas produzidas com pó de basalto não obtiveram crescimento similar àquelas que receberam adubação convencional, no entanto, neste tratamento foram observados os maiores valores de N, P, Ca, Mg, B, Fe e Mn nas folhas |
