Effect of sowing time on the efficiency and structure of buckwheat in connection with the justification of the use of complex machines

Abstract

The article investigates the problem is the need to study the optimal timing of onset and duration of sowing buckwheat as the main indicator of agro-technical requirements for the design of rational processes and technical means to implement them in connection with the development of complex machines to provide a reliable technology of mechanized cultivation and harvesting of buckwheat. The aim was to establish the influence of meteorological factors on the performance and structure of plant matter the level of buckwheat at different times of sowing. Methods of research - field and laboratorybased methods developed by leading scientific institutions of Ukraine. The observations were noted all the phases of development of plants from sowing to gathering and observations were recorded in the log. As a result of this work the following conclusions: 1.Tri years of observations allow to assert that it is impossible to ascertain the optimal calendar sowing buckwheat, which would not have been put into temporary adverse conditions and to ensure the realization of the potential of the level of productivity. And if we bear in mind the estimated time range, it borders from mid-May to mid-June. Earlier deadlines risky the possible presence of frost, and later - the lack of the required number of pollinating insects. 2. From the standpoint of the design of complex mechanization in crop production, this information will be used in terms of the fact that during the spring sowing buckwheat factor presence in the rotation can’t be tense and give engineering services of room for maneuver in the organization of work of the machine and tractor.
