Increasing the smoothness of the course of the forage harvester by optimizing the mass-dimensional and inertial parameters of its body

IOP Conference Series: Materials Science and Engineering, 2020
The scientific-methodical substantiation and practical recommendations on stabilizing the movement of forage harvesters are proposed. Calculation of optimal mass and inertial parameters of the hull, as well as elastic properties of tires as the main ...

Influence of forage harvester chopping equipment on characteristics of chips

, 2020
The modern technologies for harvesting fodder for preservation are applied by using technical equipment that performs multiple operations (cutting, chopping, transporting) in a single pass, thus contributing to cost reduction and decrease of the losses ...

Boron deficiency responses in maize (Zea mays L.) roots

Journal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Comparing mechanical harvest with alternative ground‐based methods for estimating forage yields in cool‐season annual grasses

Agrosystems, Geosciences & Environment, 2022
To accurately estimate forage yield of experimental lines and cultivars without the time and expense of harvesting with and maintaining a plot harvester would aid cool‐season forage grass researchers and breeders in cultivarselection and advancement.

Compensatory Yield Responses of Young Native Warm-Season Grass Stands to Seasonal Changes in Harvest Frequencies

Agronomy, 2022
Defoliation management can significantly affect subsequent grassland’s forage productivity and sustainability. To assess the type and persistence of native warm-season grass (NWSG) yield responses to changes in defoliation intensity, a five-year harvest ...
