Resumo: | Soil structure is defined by its physical condition, expressed by the size, shape and arrangement of solid particles and the pores are concerned. With the use and soil management in pecan orchards, soil structure is modified by soil tillage, growth and root development during cultivation. The objective of this study was to evaluate the effect of soil tillage in the growth of pecan seedlings at different times of development and, through physical-hydric soil parameters define the conditions that may favor better root and aerial plant growth. The study was conducted at FEPAGRO Forests, located in Santa Maria, Rio Grande do Sul. Soil tillage systems were: T1-Planting with small pit 0,20 x 0,60 m (PCP); T2-Subsoiler plus disking and small pit (SG); T3-Rotary hoe and small pit (ER) T4-Planting with a large pit 0,40 x 0,60 m (PCG). The experimental design was a randomized block design with 5 replications. Soil samples with preserved structure were collected in layers 0,00 to 0,10; 0,10 to .20; 0,20 to 0,40; and 0,40 to 0,60 m, to determine the bulk density (Ds), pore size distribution, air permeability (Ka), saturated hydraulic conductivity (Ksat) and the water retention curve. The soil penetration resistance (Rp) was determined in three distances around the four quadrants of pecan trees. The walnut crop growth was evaluated through the high and stem diameter at different times, the shoot dry mass, density and root length at 24 months. The planting in small pit tillage of pecan reduced root growth and vegetative growth. The soil tillage in large pit provided the highest growth in height, diameter and length of roots after 21 months to 24 months of evaluation. Subsoiler plus disking favored the retention and water availability in soil at depth between 0,40 and 0,60 m, but showed no significant difference in the results on the survival rate, root growth and vegetative pecan growth. |

Com o uso e manejo do solo em pomares de nogueira-pecã, a estrutura do solo é modificada pelo preparo do solo, crescimento e desenvolvimento radicular durante o cultivo. O objetivo deste trabalho foi avaliar o efeito dos preparos do solo no crescimento da nogueira-pecã em diferentes épocas de desenvolvimento e, através de parâmetros físico-hídricos no solo definir as condições que possam favorecer o melhor crescimento radicular e aéreo da planta. O estudo foi realizado na FEPAGRO Florestas, localizada em Santa Maria no Rio Grande do Sul. Os sistemas de preparo do solo foram: T1-Plantio com cova pequena de 0,20 x 0,60 m (PCP); T2-Subsolador mais grade niveladora e cova pequena (SG); T3-Enxada rotativa e cova pequena (ER); T4-Plantio com cova grande de 0,40 x 0,60 m (PCG). O delineamento experimental foi blocos ao acaso com 5 repetições. Amostras de solo com estrutura preservada foram coletadas nas camadas de 0,0 a 0,10; 0,10 a 0,20; 0,20 a 0,40; e 0,40 a 0,60 m, para determinar a densidade do solo (Ds), distribuição de tamanho de poros, permeabilidade ao ar (Ka), condutividade hidráulica de solo saturado (Ksat) e a curva de retenção de água. A resistência do solo à penetração (Rp) foi determinada em três distâncias em torno dos quatro quadrantes da nogueira-pecã. Avaliou-se o crescimento da nogueira através da altura e diâmetro de colo em diferentes épocas, a massa seca da parte aérea, densidade e comprimento radicular aos 24 meses. O plantio somente em cova pequena da muda da nogueira-pecã reduziu o crescimento radicular e da parte aérea. O preparo do solo em cova grande proporcionou maior crescimento em altura e diâmetro e comprimento de raízes depois dos 21 meses até os 24 meses de avaliação. A subsolagem com gradagem favoreceu a retenção e disponibilidade de água no solo na profundidade entre 0,40 e 0,60 m, porém não mostrou diferença significativa nos resultados na taxa de sobrevivência, crescimento radicular e da parte aérea da nogueira-pecã.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia FlorestalUFSMBRRecursos Florestais e Engenharia FlorestalSistema radicularDensidade do soloResistência a penetraçãoRoot systemBulk densityPenetration resistanceCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALPreparo do solo no estabelecimento inicial da nogueira-pecã carya iIlinoinensis (Wangenh.)
