Pigeonpea [Cajanus cajan (L.) Millsp.] is a favourite crop of rain-fed farmers due to its high food value, drought tolerance and various soil improving properties. The productivity enhancement of this crop has been a long-term goal at the national level but with a little success. In this context, the advent of hybrid breeding technology with over 30% on-farm yield advantages has provided a much-needed breakthrough. The hybrids in pigeonpea were bred using a stable CMS system and natural out-crossing. It is believed that the adoption of locally adapted hybrids would contribute significantly towards both family income and nutrition.

The article presents results of an empirical study of the age dynamics of the social situation of develop¬ment in primary school students in inclusive education. The study sample consisted of 328 children aged from 7 to 11, including 18 children with SEN, studying in two inclusive schools in Moscow. The hypothesis of the study was that the characteristics of the objective and subjective aspects of the social situation of chil¬dren’s development change in accordance with the two phases of primary school age. The characteristics of the social situation of the development of children were measured using the “Sociometry” method and two projective methods: “Color Test of Relationship” and “Sentence Completion Test”. The age dynamics is ob¬served in changes in the social position and the system of orienting images of primary school students. The significant differences between the distribution of sociometric statuses of students in inclusive classes and the age standard obtained in the conditions of traditional education were found. The results of the study reveal the specificity of elementary school students’ development in conditions of inclusive education.

Objective: to assess the constitutional features of the age dynamics of secondary sexual characteristics and functional parameters of city schoolchildren in the age range of 7–17 years.Materials and methods. The objects of the study were schoolchildren aged 7–17. The stages of the expression of secondary sexual characteristics were determined visually according to the scheme by J.M. Tanner. The functional parameters of the examined schoolchildren were assessed using the methods of dynamometry, spirometry; blood pressure and heart rates, as well as the time of simple sensorimotor reactions were measured.Results. As a result of the performed studies, it has been found that representatives of the hypersomnic types are ahead of other types to reveal the first stages of secondary sexual characteristics. Schoolchildren with the leptosomic morphotypes due to higher rates of their development have reached the definitive stages by the same age as those with the hypersomnic variants. The intensity of age-related changes in functional parameters (strength qualities, circulatory and respiratory systems, nervous system) in the studied objects depends on their body type.Conclusion. The stage and rate of puberty, as well as the development of functional parameters in city schoolchildren depends on their somatotype.
