Abstract | Soil management can alter the physical properties of the soil, being of great importance to ensure adequate levels of
crop productivity. The innovation of agricultural implements and machinery and excess cultural practices during handling are
the main factors that affect these characteristics. The objective of this study was to evaluate the effect of compaction of soils
with different texture classes (clay and heavy clay) on the initial growth of pea. The experiment was conducted in a greenhouse
at the Department of Fitotecnia at UFV. Itapuã 600 pea seeds were used. Each treatment consisted of 4 replicates of 50 seeds
for each compression level (T1, T2, T3 and without compression) for the two soil textural classes. Were evaluated: emergency,
IVE, VE, length of shoot and root dry weight of shoot, root mass and total dry mass. For both textural classes compaction is
not observed influence on the parameters analyzed, except for dry weight of shoots in clayey soil, IVE in clayey soil. However,
both were not directly related to the level of compression.
O manejo do solo pode alterar as propriedades físicas do solo, sendo de grande importância para garantir o
estabelecimento de plântulas e produtividade. A inovação de implementos e máquinas agrícolas e excesso de tratos culturais
durante o manejo são os principais fatores que interferem nestas características. Assim, objetivou-se avaliar o efeito da
compactação de solos com diferentes classes texturais (argilosa e muito argilosa) no crescimento inicial de ervilha. O
experimento foi montado em casa de vegetação com sementes de ervilha Itapuã 600. Cada tratamento contou com 4 repetições
de 50 sementes em diferentes graus de compactação dos solos, com aplicações três cargas sobre os solos que resultaram em:
argiloso: controle: 0,21, T1: 0,26, T2: 0,28 e T3: 0,33 MPa, textura muito argilosa: controle: 0,40, T1: 0,42, T2: 0,46 e T3:
0,53 MPa. Foram avaliados a porcentagem de emergência, IVE, VE, comprimento de parte aérea e raiz, massa seca de parte
aérea, raiz e massa seca total. Para as duas classes texturais a compactação teve influência sobre a massa seca da parte aérea no
solo com textura argilosa e para IVE no solo com textura muito argilosa. Porém, ambos não tiveram relação direta com o nível
de compactação. |
