Recomendação de cultivares de abacaxi para produção de mudas por secção de caule nas condições climáticas de Rio Branco - Acre.
Provedor de dados: 14
Autores: LEDO, A. da S.; MEDEIROS, J. A.; AZEVEDO, F. F. de.
Dentre as frutíferas de importância econômica no Estado do Acre, se destaca o abacaxi devido a sua boa produção e a sua demanda na alimentação regional. Tem-se observado a expansão da cultura principalmente como componente temporário de sistemas de produção consorciados com fruteiras e outras culturas regionais. O Centro de Pesquisa Agroflorestal do Acre desenvolveu estudos sobre o comportamento de cinco cultivares de abacaxi quanto à propagação vegetativa por secção do caule, conforme metodologia proposta por Reinhardt &amp; Cunha (1989).

Basic wood density tree species of Cerradão physiognomy in the state of Tocantins
Provedor de dados: 190
Autores: Silva, Carlos José da; Vale, Ailton Teixeira do; Miguel, Eder Pereira.
The aim of this study was to analyze the basic density of tree species of Cerradão phytophysiognomy in Cerrado domain in the state of Tocantins, and establish the relationship between the wood basic density of stems and branches. Samples of 80 trees were collected from stems (base, middle and top) and branches (thick branch, medium branch, and twig). The species had an average 0,650 g cm-3 of wood basic density. The basic density for most species (58%) decreased from the bottom to the top of the stem. The basic wood density between axial positions of the stem and the basic density of branches with different diameters showed significant relationship. According to proposed models to estimate stem density using branches density, the medium branch density...

Potato crop growth as affected by nitrogen and plant density
Provedor de dados: 86
Autores: OLIVEIRA,CARLOS ALBERTO DA SILVA.
Growth and development variables and dry matter characteristics were studied for cultivar Snowden of potato (Solanum tuberosum L.) to evaluate nitrogen and plant density influence. Disregarding ending of season plant stress, the average number of actives haulms per plant was five and it was not affected by plant spacing. However, seasonal and final number of active haulms per plant were increased at 200 kg/ha of nitrogen. Maximum stem elongation was reached quickly with double density and had the tendency to keep constant at the highest and lowest nitrogen levels after 70 days after planting. Specific stem mass defined as mass per unit stem length was established as an indirect measure of stem thickness and load capacity. Specific leaf mass position in...

Development of seedlings of Red Pitaya (Hylocereus undatus Haw) in different substrate volumes - DOI: 10.4025/actasciagron.v30i5.5970
Provedor de dados: 1
Autores: Andrade, Renata Aparecida de; FCAV/UNESP/Jaboticabal; Martins, Antonio Baldo Geraldo; UNESP; Silva, Marco Túlio Habib; UNESP.
With the ever-increasing search for alternatives by producers and demand for exotic fruits by consumers, the market for fruits species has grown considerably. In this context, the pitaya has been sought not only for its exotic appearance, but also for its organoleptic characteristics. The present research was conducted with the objective of evaluating the influence of the substrate volume in the development of seedlings of red pitaya, by using polystyrene trays expanded with different volumes of cells: 10, 15, 30 and 65 mL. The evaluations, conducted during 90 days, evaluated: survival percentage; number and height of stems (cm); largest root length (cm); fresh and dry masses of the stems and roots (g). The delineation was entirely randomized. The values...

Morphological and structural characteristics of Urochloa decumbens Stapf. deferred pasture grazed by heifers under two periods of protein-energy supplementation
Provedor de dados: 2

The aim of this study was to evaluate the morphological and structural characteristics of deferred Urochloa decumbens Stapf. ‘Basilisk’ grazed by Nellore heifers under two periods of protein and energy supplementation (PES). The experiment was carried out from Jun 21 to Nov 15, 2016, under a completely randomized design and two PES periods (55 [P55] and 147 [P147] days). Forage mass (FM), leaf blade dry mass (LBDM), stem dry mass (SDM), dead material dry mass (DMDM), canopy height (CH), and forage bulk density (FBD) were evaluated. Data were analyzed by the SAS® PROC MIXED procedure and treatment means were compared with the Student's t test (p &lt; 0.05). LBDM was higher for P147 heifers after 21, 84, and 126 days of grazing, similar to those observed...

Épocas de poda na cultura da mandioca na região noroeste do Paraná, Brasil
Provedor de dados: 52
Autores: Takahashi,Mário.
Este trabalho teve por objetivo avaliar o efeito da poda da parte aérea, realizada em três épocas distintas, sobre alguns parâmetros fitotécnicos da mandioca (Manihot esculenta Crantz). Todos os tratamentos foram plantados em outubro de 1991. Em 1992, efetuaram-se as podas da parte aérea em maio, julho e outubro. A testemunha foi conduzida sem poda. Em maio de 1993, todos os tratamentos foram colhidos. As produções da parte aérea na poda, foram alteradas pela quantidade de folhas. As produções fresca e seca das raízes e da parte aérea e o índice de colheita, foram modificados após a poda, em relação ao tratamento sem poda. O stand final e o número de raízes por planta, não foram alterados pela poda.
