INFLUENCE OF HERBICIDE TREATMENT ON YIELD SPRING RAPE IN THE FARMS OF THE MAGZHAN ZHUMABAYEV DISTRICT OF THE NORTH KAZAKHSTAN REGION

Abstract

The research work is devoted to the study of the effect of herbicide treatment on the yield of spring rapeseed in the farms of the Magzhan Zhumabayev district of the North Kazakhstan region. Field experiments were conducted to study the effect of herbicides on weed vegetation and the yield of spring rapeseed oil seeds. The timing of sowing spring rapeseed is the end of May. The species composition of the weed vegetation of rapeseed agrophytocenosis was determined. The most common weeds in spring rapeseed crops are tilted schiritsa, common shepherd's bag, white mar, field osot, creeping wheatgrass. The type of clogging of crops is root-sprout-annual. The soil of the experimental field is a complex of leached and ordinary chernozems. The objects of the study were selected herbicides "Simba" and "Hacker". These drugs are aimed at combating annual and perennial weeds. They have a systemic effect, are absorbed by the leaves, transferred to the point of growth, roots and rhizomes and easily move around the plant, disrupting cell division and stopping its growth. The drug Simba has a high efficiency in the fight against monocotyledonous weeds in spring rape crops, the average efficiency for 28 days was 28.9%. Hacker herbicide is effective for controlling dicotyledonous juvenile and perennial weeds, providing an average efficiency of 40% in 28 days. Among the processing options, the most optimal from the point of view of crop quality was the treatment with Hacker preparation in compliance with the recommended consumption rate. The quality of the crop in this variant is close to the harvest with manual weeding and differs by only 3-5%.
