Previous issue date: 2011 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (Capes) / O presente trabalho teve como objetivo avaliar resposta de diferentes l?minas de irriga??o definidas a medi??o di?ria pela ETo em minijardim clonal para produ??o de mudas de eucalipto h?brido de E. urophylla S.T. Blake e E. grandis W. Hill ex Maiden. O experimento foi conduzido no viveiro da Empresa Sada Bio Energia e Agricultura LTDA, Sete Lagoas (MG), no per?odo de abril a novembro de 2010. No minijardim clonal, adotou-se o delineamento em blocos casualizados, contendo sete l?minas de irriga??o e quatro blocos, totalizando em 28 unidades experimentais. Nos demais setores do viveiro (casa de vegeta??o, casa de sombra e aclimata??o a c?u aberto), o delineamento foi de blocos casualizados, contendo sete l?minas de irriga??o, quatro blocos e dois n?veis de redu??o foliar, totalizando em 56 unidades experimentais. Os tratamentos foram definidos de acordo com a leitura diariamente do Tanque Classe A (T1 = 50% da ETo - freq??ncia ?nica ; T2= 75% da ETo ? duas vezes ao dia; T3 = 100% da ETo ? duas vezes ao dia; T4 = 125% da ETo ? tr?s vezes ao dia; T5 = 150% da ETo ? tr?s vezes ao dia; T6 = 100% da ETo - freq??ncia ?nica e T7- operacional da empresa - l?mina 10,66 mm dia-1, fertirriga??o oito vezes ao dia, durante cinco minutos com uma vaz?o de 0,8 L h-1. A l?mina 1,46 mm dia-1 (T1 - 50% da ETo) ? recomendada para irriga??o de minijardim clonal para produ??o de mudas de eucalipto. Sem redu??o foliar da miniestaca pode ser utilizado na produ??o de mudas de eucalipto. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2011. / ABSTRACT This work had as its main objective to evaluate the response from different irrigation water levels, defined the daily measurement through ETo in clonal mini gardens to the hybrid eucalyptus E. urophylla S.T. Blake and E. grandis W. Hill ex Maiden plants production. The experiment was conducted at the Sada Bio Energia e Agricultura Ltda Company, in the city of Sete Lagoas, Minas Gerais state, Brazil, between April and November, 2010. In the mini-clonal garden, it had been adopted the randomized block design, with seven irrigation water levels and four blocks, totaling 28 experimental units. In the other sectors of the nursery (greenhouse, shade house and acclimation to the open air), the design was in randomized blocks with seven irrigation levels, four blocks and two levels of reduction of foliar area, totaling 56 experimental units. The treatments were defined according to the daily reading of the Class A Tank (T1 = 50% of ETo ? single frequency ; T2= 75% of ETo ? twice a day; T3 = 100% of ETo ? twice a day; T4 = 125% of ETo ? three times a day; T5 = 150% of ETo ? three times a day; T6 = 100% of ETo ? single frequency e T7- company?s operational - level 10,66 mm day- fertilizer and irrigation eight times a day for five minutes with a flow rate of 0.8 L h-1. The level 1.46mm a day -1 (T1 ? 50% of ETo) is recommended for irrigation in clonal mini gardens for eucalyptus sprouts production. Without reduction of the mini sprouts foliar area, can be used for the production of eucalyptus plants.
