Influence of seeding terms on productivity and quality of sunflower

Abstract

An important reserve for increasing the yield of sunflower, along with the introduction of new high-yielding varieties and hybrids, is to improve agricultural techniques, especially the choice of the most optimal sowing dates. With adaptive technology of cultivation sowing sunflower in optimal time is one of the most important conditions that determine the timely, even and complete germination and further good development of plants. The aim of the research is to study the elements of adaptive technology of sunflower cultivation to provide vegetable oil producers with high-quality raw materials. As a result of the research data on the study of elements of adaptive technology of sunflower cultivation, namely the timing of sowing in the West Kazakhstan region. According to the research, in the conditions of the 1st zone of the West Kazakhstan region to obtain a full crop of sunflower it is advisable to produce earlier terms — when temperature of the soil at the depth of seeding is 8–10 °C. Early sowing has a positive effect on the growth and development of sunflower, increases the collection of oilseeds.
