“…Eucalyptus hybrids also showed a significant difference (p < 0.05) in relation to height, with a higher value for the Grancam hybrid. This trend of higher growth in height presented at 45 months by the hybrid Grancam has been verified since its initial development (7 to 17 months) (Jung et al, 2017). It may be related to a better interaction of the genotype with the environment, which allowed its higher growth.…”

This study aimed to evaluate the influence of drip irrigation and micro-sprinkler on the dendrometric parameters of two Eucalyptus hybrids at 45 months. The experiment was carried out in Aquidauana, MS, using an experimental design of randomized blocks in split plot scheme. The dendrometric attributes of the trees evaluated were height, diameter at breast height, volume, shape factor, taper, and dry mass production. The Grancam hybrid has the highest growth in height, and the Urograndis has the largest diameter at breast height. Drip irrigation provides an increase of 36.7% in the wood volume of eucalyptus hybrids when compared to those that were not irrigated.

“…Thus, it can be affirmed that irrigation provided greater growth of eucalyptus, avoiding possible metabolic disturbances caused by water deficit. Jung et al (2017) also noted that irrigation was essential so that the height of eucalyptus in the early stages have significantly bigger growth than non-irrigated eucalyptus. There was an increase in height to the irrigated treatments of 8.2 and 4.6% for drip and micro-sprinkler, respectively, to 65º MAP, in relation to treatment without irrigation.…”

In order to maximize the productivity of forest species, techniques such as irrigation have been used. The objective of this study was to evaluate the water use efficiency and the influence of the irrigation located in the growth of the hybrids of eucalyptus Grancam and Urograndis at 65 months. The study was carried out in the experimental area of the State University of Mato Grosso do Sul (UEMS), in Aquidauana (state of Mato Grosso do Sul, Brazil). The experimental design was randomized blocks with subdivided plots. The treatments used in the plots were two irrigation systems (microsprinkler and drip) and one control treatment with no irrigation (dryland), and in the subplots, the two hybrids of eucalyptus: Grancam (Eucalyptus grandis x Eucalyptus camaldulensis) and Urograndis (Eucalyptus urophylla x Eucalyptus grandis), submitted to irrigation up to the 53° month after planting (MAP). The results were submitted to the analysis of variance and the Tukey test for means comparisons at 5% of probability. The use of irrigation in eucalyptus influences the productivity, providing increased wood volume, height of plants and diameter at breast height (DBH). The hybrid Grancam showed greater increase in height, and Urograndis increased in DBH. The higher efficiency of water use for the volumetric production of wood was observed in drip irrigation for the hybrid Grancam. The hybrid Urograndis is more efficient in the use of water for the volumetric production of wood regardless of the treatment.

“…Trabalhos discutem que plantas jovens de mogno possuem regulação da abertura estomática que permite o controle da perda de água via transpiração (ALBUQUERQUE et al, 2013), o que auxilia na eficiência de uso de água e na manutenção do desenvolvimento das plantas frente a déficit hídrico. Considerando que são espécies com origem em regiões tropicais, é esperado que tenham estratégias evolutivas para melhor desenvolvimento sob condições de alta temperatura e períodos de seca, considerando que essas condições afetam processos vitais das plantas (JUNG et al, 2017). Casaroli et al (2016), observaram que o consumo de água pelas plantas de mogno em fase inicial de crescimento possui forte relação com as variáveis micrometeorológicas locais.…”

RESUMOO objetivo deste trabalho foi avaliar o crescimento de plantas jovens de mogno-africano, após a interrupção de diferentes manejos de irrigação dos primeiros anos do ciclo. O trabalho foi desenvolvido em Bonfinópolis-GO, em Latossolo Vermelho Distroférrico, em março de 2012. O delineamento experimental adotado foi em blocos completos casualizados, com três repetições e 10 tratamentos (15 plantas por parcela), em arranjo bifatorial com 3 quantidades de gotejadores por planta (01, 02 e 03 gotejadores por planta) e 3 vazões de gotejadores (2 L.h -1 , 4 L.h -1 e 8 L.h -1 ), e a testemunha sem irrigação. Após dois anos de cultivo irrigado todos os tratamentos foram interrompidos (novembro de 2013). Cinco anos depois (novembro de 2018) não foi observado diferença significativa para as variáveis altura de planta, altura de fuste e diâmetro a altura do peito (DAP). O incremento médio da altura de plantas de mogno-africano após cessar a irrigação foi de 15,6m, da altura de fuste foi de 13m e do DAP foi 0,14m. Os resultados mostraram que é dispensável o uso de irrigação para o cultivo de mogno-africano, uma vez que as diferenças em altura de planta, fuste e DAP foram significativas apenas nos dois primeiros anos de cultivo e não se mantiveram nos anos seguintes.
