At a 0° blade angle and in a bundle arrangement, the maximum shear force and shear strength values for cutting eight stems were 42.17 N and 0.45 MPa, while at 20°, they were 31.81 N and 0.32 MPa, respectively. Figure 4. The maximum shear force and shear strength at 0°, 20° and 40° blade oblique angles for eight stems in row and bundle arrangements.

Crushing plant stems was proposed to reduce pressure required for bulk compaction. • Changes in compression/relaxation behaviour were examined using uniaxial compression. • Crushing the material reduced the peak stress at a density of 256 kg m −3 by 41-44%. • Stress relaxation profiles were affected by moisture content, but not by crushing. •

Each node grows one leaf, fruit, tendril, and a new stem. When pruning, we'll remove the new stem. This is referred to as the growth point, shoot, or lateral runner. The flower and leaf may also be pruned, but only in certain situations. Pruning is very important but not the only necessity for growing cucumbers.

Designed to sever small stems and branches (up to ½-inch in diameter), anvil pruners use a crushing rather than cutting action, so are suitable for trimming dry dead branches, which snap easily. Anvil pruners are not recommended for soft green branches and stems, which can become crushed and frayed by the shears.

Raking helps alfalfa in swaths dry more quickly by turning over wetter plant material and exposing it to sunshine and air. However, the optimum raking time is when the moisture content is between 35 and 40%. Raking when it is too wet will lead to twisting of the plant materials, and this may eventually lead to a longer period of drying.

The best moisture content to rake for low loss and good drying is between 30 and 40%. In dry weather periods, hay can be raked in the evening or early morning when leaves are moist and less prone to shatter. Raking at the proper time can reduce field-curing time a few hours to allow an earlier start at baling.
