Purpose: to analyze the experience of Russian scientists in the field of application of a differentiated approach to agricultural crops irrigation. The overview of research work of domestic scientists on the use of an irrigation system in agriculture, in which the provision of agricultural crops with water to maintain a given level of the minimum water capacity will be carried out during the most critical periods of their growth and development is presented. During irrigation, the timing, frequency, irrigation rates depend on the level of groundwater occurrence, agrochemical properties of soils, weather and climatic conditions, phases of growth and development of crops. The application of a differentiated irrigation regime to maintain a given level of pre-irrigation moisture allows increasing the productivity of agricultural crops, the quality of products obtained while reducing irrigation and watering rates, the number of waterings. Conclusions. The study of the results of research work of domestic scientists in the field of influence of irrigation and the fertilization system on the yield and quality of agricultural products allows concluding that obtaining the planned yields is possible only if irrigation regimes are observed and the level of soil fertility is maintained by applying various fertilizers. The use of a differentiated approach to irrigation while maintaining a given level of pre-irrigation soil moisture during critical periods of crop development allows reducing irrigation water consumption and optimizing irrigation rates and their quantity. The study of a differentiated irrigation regime is promising now and in the near future, taking into account the deteriorating water supply in the territory of our country, associated with a change in weather and climatic conditions.

Nutrient Partitioning

Appropriate nutrient partitioning between the maternal body and gravid uterus is essential for optimum fetal growth and neonatal survival, and in adult sheep nutrient partitioning during pregnancy generally favours the conceptus at the expense of the dam. However, recent studies using an overnourished adolescent sheep model demonstrate that the hierarchy of nutrient partitioning during pregnancy can be dramatically altered in young growing females. Overnourishing the adolescent dams to promote rapid maternal growth throughout pregnancy results in a major restriction in placental mass and leads to a significant decrease in birth weight relative to moderately-fed adolescents of equivalent gynaecological age. High maternal feed intakes are also associated with an increased incidence of non-infectious spontaneous abortion, a reduction in gestation length and colostrum production, and a higher incidence of neonatal mortality. The present paper examines the putative role of a variety of endocrine regulators of nutrient partitioning in this unusual model system, where the dam is overnourished while the stunted placenta restricts nutrient supply to the fetus. The central role of nutritionally-mediated alterations in placental growth and development in setting the subsequent pattern of nutrient partitioning between the maternal body, placenta and fetus is examined, and critical periods of sensitivity to alterations in maternal nutritional status are defined. Finally, the consequences of this form of inappropriate nutrient partitioning on the growth and development of the fetus and neonate are described with particular emphasis on the reproductive axis.

We have studied the dynamics of growth and development of chicken egg production of line cross “Hayseks brown” from day age to the age of peak performance. During the experiment, the study of the intensity of metabolic processes in the body of 6, 35, 90, 120, and 150 day-olds, i.e., in critical periods when there is intense growth of feathers and juvenile molten (30–60 days), the beginning of the oviposition (120 days) and the beginning of an intensive oviposition (150 days). In these age periods, the level of soluble proteins, amine nitrogen, and the activity of alanine and aspartate aminotransferases were determined in liver tissues, cuticles of the muscular stomach, gastrointestinal mucosa, gastrointestinal mucosa, duodenum and pancreas. As a result of the research, it was found that the intensity of the growth of chickens is different from the recommendation for the “Hayseks Brown” cross. Only at the age of 119–126 days growing the body weight of the reared chickens coincides with the recommended technology for hens of the cross “Hayseks Brown”. The results of biochemical studies are related to changes in the physiological state and magnitude of gains. During the growth of repair young poultry, in the critical periods of growth and development, it is necessary to deliberately affect the processes of protein metabolism by enhancing the processes of digestion and assimilation of nutrients and biologically active substances of fodder and the sufficient introduction of free amino acids by the use of exogenous enzyme preparations.

Purpose. Determination of the influence of seed biodisinfectant, stimulator of growth and foliar feeding on the white lupine growth and development in the context of climate change. Methods. Field (to study the interaction of the object of study with biotic and abiotic factors); morphophysiological (for biological control over development of productivity elements at the stages of organogenesis); weight (to establish the indicators parameters of the crop structure elements and determine the grain yield); statistical (statistical processing of the research results). Results. The results of the analysis of the indicators of the average daily air temperature and the amount of precipitation from April to August and their comparison with long-term values are presented. Indicators of height and aboveground mass of white lupine plants in dynamics, depending on the pre-sowing seed treatment, plant growth stimulant and foliar feeding, correlation dependences of these indicators on the hydrothermal conditions of the growing season have been established. Conclusions. The growth and development of white lupine plants depends on the elements of the technology of its cultivation, as well as hydrothermal conditions during the growing season of the crop. The highest plants (83.0 cm) with their maximum weight (143,8 g/plant) were noted in the variant where the seeds of white lupine were treated with БТУ-р bioinoculant simultaneously with the MicoHelp biodisinfectant and foliar feeding of plants with micronutrient fertilizer Trazex at the ІХ stage of organogenesis was carried out. Mathematical models have been developed that confirm the close relationship between the level of height indicators and the aboveground mass of white lupine plants with weather conditions, the critical periods of their influence in the ontogenesis of plants were also determined.

The changes the of intestinal microflora composition of Beijing broiler ducks at introduction of caroteneproduced yeast Phaffia rhodozyma biomass to the diet was studied. The positive changes of 37-days ducks intestinal microflora were revealed after two weeks of yeast P. rhodozyma biomasses application in 6- day-old birds’ diet (1 % of the weight of feed). It was a decrease of the E. coli total number and pathogenic staphylococci strains, the absence of Enterobacteriaceae (lac–) strains against the high number of bifidobacteria and lactobacilli. The E. coli total number reduced by 10 times at the expense of E. coli (lac±)-strains compared to 37-day birds three weeks after the experiment. The staphylococcus non-pathogenic strains number in 58-days ducks experimental group caecum contents reduced compared to 37-day birds three weeks after the experiment. Thus, the using of caroteneproduced yeast P. rhodozyma biomass in poultry diets helps to prevent violations of intestinal microflora and occurrence dysbiosis at critical periods of growth and development.

Breast milk is the main diet of infants as it provides all the nutrients for normal growth and development of a baby from the time of birth to the first 6 months of life. This dynamic fluid provides a diverse array of bioactive substances to the developing infant during critical periods of brain, immune system and gut development. In Ayurveda though breast milk is vital for children and infants but it may be vitiated with Dosha (regulatory functional factors of the body) due to the faulty lifestyle of the Dhatri (wet-nurse or mother) which may lead to various type of morbidities in child according to predominance of Dosha. Ancient Ayurveda scholars have also mentioned effect of breast milk according to taste and texture along with management of morbidities caused by these predominance’s of Dosha. Ayurveda have stressed very much on this aspect and have given a detailed account of abnormalities of breast milk and their consequences. Knowledge of this fact is of key significance for the proper growth and development of a child. Therefore, evidences from Ayurveda have been compiled in this article to understand the effect of breast milk on child morbidity status.

This chapter reviews the concepts of developmental plasticity and mismatch, critical periods for exposures, and the emergent science of epigenetics to explain how relatively subtle changes in parental behaviour can affect the outcomes of pregnancy, and why there are echoes of such influences across the whole of life. Contrary to earlier belief that embryonic and fetal development is set by a genetic programme, it is now clear that the fetus responds to cues in the in utero environment and can alter its development and metabolism accordingly. The ‘decisions’ that the developing fetus makes are embedded in its biology and are based on information it receives from its mother and, through her, about the wider environment, in terms of nutrition and physical activity but also about stress and other aspects of lifestyle.

Objective. To estimate adaptation of an organism of the babies born with different types of light severity of a delay of pre-natal growth and development. Material and methods. 609 children are examined. Since the birth under observation 141 children, from them are born in the result of the complicated pregnancy and childbirth, including with asymmetric type of light severity of a growth inhibition and development of a fruit – 57 (Group 1a) and with symmetric – 15 (Group 1b) and without that – 69 (Group 2) from mothers with the burdened somatic and obstetric and gynecologic anamnesis. Children are full-term, mature, looked round in 1 (131), 3 (118), 6 (109), 12 (110 children) months. Outcome recording methods were a comprehensive case history analysis, physical examination, assessment of cardiointervalography and body adaptation to the environment. Distribution-free statistical analysis methods. Results. At children in Groups 1a and 1b satisfactory adaptation of an organism to conditions of the environment took place at the birth of 28. 07 and 26. 67%, in 1 month of 32. 69 and 35. 71%, in 3 months of 31. 11 and 25%, in 6 months of 51. 16 and 46. 15%, in 12 months of 48. 78 and 36. 36%. Tension and an overstrain of adaptation is recorded at 22. 81 and 40%, 36. 54 and 28. 57%, 33. 33 and 41. 67%, 30. 23 and 23. 04%, 19. 51 and 18. 18%. Unsatisfactory adaptation is defined at 42. 11 and 13. 33%, 21. 15 and 21. 43%, 24. 44 and 16. 67%, 11. 63 and 23. 04%, 21. 95 and 18. 18%. Failure of adaptation is revealed at 7. 02 and 20%, 9. 62 and 14. 29%, 11. 11 and 16. 67%, 6. 98 and 7. 69%, 9. 76 and 9. 09% of children respectively. Conclusion. Study of characteristics of body adaptation to the environment in the scientific community is a perspective area, and any practical application (starting with perinatal centres) of assessment of body adaptation to the environment with follow-up groups identification and further determination during critical periods of growth and development (outpatient monitoring) justify patient-specific approach to outpatient follow-up of infants born with different types of mild intrauterine growth and development retardation.

Sum Of Active Temperatures

Soybean has an ecological adaptability due to the deep selectivity of this crop in relation to the specific features of the growing zone. At the same time, it makes increased demands on heat and moisture, especially during certain "critical" periods of growth and development. The lower threshold of active average daily temperatures is 15–17oC, and for full maturation of ultra-ripe and early-maturing varieties, the sum of active temperatures of 1700–2100oС is required. Assessment of the agro-climatic resources of the Ryazan region indicates the possibility of growing precocious soybean varieties here. The limiting indicator in some critical periods may be insufficient moisture. As a result of the conducted research, it was found that soybean varieties of the Northern ecotype are able to form a stable yield in the conditions of the Ryazan region. At the same time, the lesser response to changes in agroclimatic conditions was shown by the Kasatka variety, which showed the shortest growing season and yield at the level of 1.00 t / ha. The Georgiya variety reacted more than any other to changes in weather conditions, its yield was from 1.24 to 1.72 t/ha over the years of research.
