Protein plays a critical role in both the nutrition and biological functions of milk, which is an important part of a balanced diet. In this study, we installed and implemented the fully automated Kjeldahl method, enabling the precise determination of the total protein content in cow milk. The investigation involved cow milk samples collected from Yerevan markets, representing 9 producers, over the years 2021 and 2022. The mean total protein content in the analyzed milk samples was found to be 2.93 g per 100 g.To determine the significance and contribution of milk protein in the adult population’s diet in Armenia, the daily protein intake through milk consumption was evaluated. Two consumer clusters were identified: one with moderate milk consumption (0.067 kg per day) and another with higher intake (0.208 kg per day). The contribution of milk protein to the overall protein intake in the diet of the adult population ranged from 2.62 % to 8.13 %. Despite varied levels of milk protein consumption, it is essential to acknowledge that Armenian protein sources extend beyond milk.

Brandy spirits, matured for three years and produced with various yeasts, were examined to assess their quality. The study included evaluating sensory indicators and conducting a qualitative and quantitative analysis of volatile aromatic compounds. Results showed that brandy spirits fermented with “Oenoferm Bouquet” yeast, displayed the highest concentrations of volatile aromatic substances, with this variant receiving the most favorable tasting evaluation among the sampled spirits.

Drought is one of the main abiotic stresses that depends on soil type and rainfall patterns on agrarian land. However, it is mainly responsible for major yield losses in crops. Climate change further compounds the challenges to advanced crop yields. Failure stress reduces crop yield. This research was conducted on grain yield in fifteen Armenian and Iranian wheat varieties to evaluate grain yield and drought tolerance indices. The study was performed with three replications under normal and drought-stress conditions for two years. According to grain yield, eight drought tolerance indices are estimated, including stress tolerance (STI), tolerance index (TOL), stress susceptibility index (SSI), mean productivity (MP), harmonic mean (HM), geometric mean (GMP), yield index (YI), and drought index (DI) for all varieties. The combination of yield analysis, eight drought tolerance indices, and correlation revealed that Navid, Voskehask, Sabalan, and Zare varieties were desirable for drought tolerance. Other varieties were identified as semi-tolerant and sensitive to drought stress.

Presents a modern approach to the agricultural industry, including horticulture, forestry, natural resources, and the environment, with emphasis on the basics of plant and animal production.

Agriscience Mechanics is an exciting new approach that connects important science principles with mechanical skills. This approach adds meaning and excitement to the traditional areas of agricultural mechanics. It is right in line with the expectations of agricultural industry. - Preface.

AgriScience Explorations, Second Edition is for you -- a student who is beginning to study agriculture. It uses approaches and content for grades 7 through 9. Photographs have been used to make your study more exciting. Many of these feature young people. This will help you see how you can be a part of today's agricultural industry. A modern approach to the agricultural industry is used in the book. Horticulture, forestry, natural resources, and the environment are included. Of course, the basics of plant and animal production are emphasized. The content is based on areas of science. The book has several chapters on being successful in agricultural education. It includes areas of personal development, such as leadership. - Preface.

This new Fifth Edition provides students with a comprehensive introduction to the agriculture industry. Updated photos and easy-to-understand text introduce students to a variety of interesting agriscience concepts and skills, including agriscience career clusters and pathways, how science is used in agriculture, real-world applications of agriscience, and what it means to be a professional in the agriscience industry. New chapters on leadership and student organizations such as FFA have been added with a focus on developing the traits that define a successful member of the agriscience community. Expanded coverage of genetics, biotechnology, food safety, entomology, and agricultural mechanics makes this edition a comprehensive learning tool for students interested in an agriscience career. - Back cover.
