Agricultural Research Updates. Volume 23 opens with a study wherein cryoprotectants such as hydrocolloids, kappa- and iota-carrageenans, xanthan gum and dairy proteins were added to mashed potatoes to investigate ways of improving the effects of freezing and thawing. Samples containing 0.5 and 1.5 g kg-1 added XG were preferred organoleptically due to the creamy mouthfeel they produced, and the instrumental texture profile analysis consistency correlated well with sensory texture attributes. Following this, the authors present the results of some noticeable studies on organic agriculture and innovative crops are discussed as a strategy reducing the risks of climate change on animal feed supplies. During the last two decades, several studies have been conducted on the evaluation of the growth performance and quality of crops under the organic cropping system, with the obtained results suggesting that in many cases yield and quality were comparable between organic and conventional systems. Also in this book, a study is included in which it is concluded that wintering root systems of the goldenrod type protect themselves from metal stress caused by basipetally obtruded excess minerals, as well as reduce the mineral load to the root functional level via exudation rather than to act as a sink for macro- and micronutrients. This means that these perennials share an immediate dependence on the availability of soil minerals with annual plants. In the conserving nutrients released by herbage and roots, the buffering capacity of the soil that is commonly improved by perennial plant covers may be more essential than any internal root storage potential. Later, the authors examine the present knowledge concerning silage quality, in relation to the wilting degree and ensilability characteristics of some grass silages or haylages, for the following crops: lucerne, red clover, sulla, sainfoin, galega, foxtail millet, orchardgrass, and chia. Afterwards, the authors discuss the Peterhof genetic collection of rye, created over the past 60 years and initially under the direction of V. S. Fedorov. The collection includes accessions with individual morphological mutations and their combinations, the meiotic mutants, inbred lines with identified mutations of self-compatibility. The close linkage of self-compatible mutation in the locus S with isozyme marker Prx7 suggests a scheme for the introduction of individual selection for improvement and differentiation of rye varieties. The subsequent study aimed to compare the retail yield quality of meat from young bulls and steers fed diets based on mycorrhizal (Myc) and conventional corn (Conv). The trial was carried out on the meat of 10 steers received a Myc corn diet, 10 steers and 10 bulls received a conventional corn diet. The chemical composition of meat, in particular the fatty acid (FA) profile and the rheological characteristics, such as meat cooking shrinkage, together with the Vis-NIR-IR properties of the thawed and the freeze-dried specimens were evaluated. In an additional study, the authors suggest that efficiency payments in Swiss agriculture show that such payments have complex side-effects, casting doubt on their overall positive contribution. A structural equation model, based on a survey of Swiss farmers, shows that promoting no-tillage leads to greater use of glyphosate and that other programs lead to over-mechanization and increased pressure on the soil. In the concluding study, CAD models were subjected to a FEA to determine whether they support the intended workloads (static analysis), and therefore, to ascertain whether the design is well dimensioned or would not withstand operating conditions. The results for stress distribution, deformation, displacement, and safety coefficient demonstrate that although the press works properly, it is oversized and its design could be optimized to save manufacturing costs.
