Resumo: | The objective of this study was to evaluate the vegetative growth and yield performance of three oil palm varieties in the juvenile phase, identifying cultivars with better adaptation on savannah environment and changed forest of Roraima (Brazil). Two experiments were conducted in two locations and distinct periods: the first experiment, for the vegetative development, was conducted in Savannah area (with supplementary irrigation) of Boa Vista (State capital), the other was a changed forest area in the municipality of Caroebe (south of the State), conducted between August 2008 and April 2010.The second experiment for the performance was conducted between January and December 2011 in both locations. The cultivars were: BRS C-2528, C-3701 and BRS C-2301, arranged in randomized complete blocks experimental design with six replications. Eighteen monthly evaluations were made to evaluate the vegetative development, the number of emitted leaves, leaf length 4 (cm) and girth circumference (cm). The performance evaluations were made by 12 collections per month, were they: the number of bunches ha-1, average weight and total production of bunches ha-1. Individual and joint variance analyses were made. The Scott & Knott test (5%) was made for the comparison of the evaluated. The Pearson correlation coefficients (r) were estimated to the average values of the performance characteristics in each environment. In the changed forest environment, the cultivars presented a higher vegetative growth than savannah environment. All the cultivars had a similar vegetative development in savannah environment. The BRS C-2301 cultivar had best results in the forest environment having larger vegetative development considering the number of leaves and the fourth leaf length. The three cultivars in forest environment showed different productive performance between them, producing between 19 and 23 tons of bunches / ha / year, especially the BRS C-2301, which was the most productive, and showed potential for field use. In savannah environment the three cultivars showed a similar performance between itself, producing between 4,5 to 6,0 tons bunches / ha / year), it was a low production, when compared to those obtained in the changed forest environment. The highest yields of bunches in the savannah environment, were due to the production of higher number of bunches and were concentrated in the months of March, April and May (rainy season), while in the forest environment were due to the higher average weights of the clusters and were concentrated in the months of October, November and December (dry season). |

Foram conduzidos dois experimentos em dois locais e períodos distintos; o primeiro experimento referente ao desenvolvimento vegetativo foi conduzido, um em área de savana (com irrigação complementar) no município de Boa Vista e o outro em área de floresta alterada localizada no município de Caroebe, no sul do Estado de Roraima realizado no período de agosto de 2008 a abril de 2010; o segundo experimento referente ao desempenho produtivo foi realizado entre janeiro e dezembro de 2011 em ambos os locais. As cultivares avaliadas foram: BRS C-2528, BRS C-3701 e BRS C-2301, arranjadas em delineamento experimental de blocos ao acaso com seis repetições. Para avaliar o desenvolvimento vegetativo foram realizadas 18 avaliações mensais, quanto ao número de folhas emitidas, comprimento da folha 4 (cm) e circunferência do coleto (cm). O desempenho produtivo foi avaliado por meio de 12 avaliações mensais, quanto: ao número de cachos ha-1, peso médio e produção total de cachos ha-1. Foram realizadas análises de variância individuais e conjuntas. Para a comparação das médias das características avaliadas foi utilizado o teste de Scott & Knott em nível de 5% de probabilidade. Adicionalmente, coeficientes de correlação de Pearson (r) foram estimados entre as médias das características avaliadas para o desempenho produtivo, para cada ambiente. No ambiente de floresta alterada, as cultivares apresentaram desenvolvimento vegetativo superior ao obtido no ambiente de savana. Todas as cultivares apresentaram desenvolvimento vegetativo semelhante no ambiente de savana. Em ambiente de floresta destacou-se a cultivar BRS C-2301 por ter apresentado maior desenvolvimento vegetativo considerando o número de folhas emitidas e o comprimento da folha 4. As três cultivares no ambiente de floresta alterada apresentou desempenho produtivo diferentes entre- si, produzindo entre (19 e 23 t cachos/ha/ano), com destaque para a cultivar BRS C-2301, que foi a mais produtiva, e mostrou-se com potencial para indicação e uso. No ambiente de savana as três cultivares apresentaram desempenhos produtivos semelhantes entre si produzindo entre 4,5 a 6,0 t cachos/ha/ano, sendo uma produção baixa, quando comparados aos obtidos em ambiente de floresta alterada. As maiores produções de cachos, no ambiente de savana, foi em decorrência do maior número de cachos produzidos e ficaram concentradas nos meses de março, abril e maio (início do período chuvoso), enquanto que, em ambiente de floresta alterada foram decorrência dos maiores pesos médios dos cachos e ficaram concentradas nos meses de outubro, novembro e dezembro (período seco).Universidade Federal de RoraimaBrasilPRPPG - Pró-reitoria de Pesquisa e Pós-GraduaçãoPOSAGRO - Programa de Pós-Graduação em AgronomiaUFRRCordeiro, Antonio Carlos Centenohttp://lattes.cnpq.br/8617553649405571Maciel, Francisco Clemilto da Silva2022-03-17T13:22:42Z20122022-03-17T13:22:42Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMACIEL, Francisco Clemilto da Silva.
