Issue №: 2 (41)
This issue of the journal is dedicated to current issues in improving technological methods for crop cultivation. Significant attention is given to the specifics of growing vegetable, grain and leguminous crops, which play a vital role in ensuring the state's food security. The scientific publications present the results of experimental research on the production of organic leguminous products, the importance of adaptive breeding to increase the resilience of agrocenoses, plant protection against harmful objects and the application of fertilizers to increase crop yields. Certain papers are devoted to the implementation of innovative methods for stimulating the seed productivity of forest seed plantations.
INFLUENCE OF SOWING TIMES ON OVERWINTERING AND YIELD OF WINTER RAPE
Serhiy Banul, postgraduate student of the Department of Agriculture, Soil Science and Agrochemistry of Vinnytsia National Agrarian University (Sonyachna St., 3, Vinnytsia city, 21008. tel. 0989928496, ORCID: https://orcid.org/0009-0001-4655-7889).
Based on the fact that the sowing dates of winter rapeseed, according to scientists, vary from July to September inclusive, there is a need to clarify them for modern high-yielding hybrids, which determines the relevance of the topic.The purpose of the research is to establish the optimal sowing dates for winter rapeseed when growing intensive hybrids that guarantee successful wintering and high productivity. Three sowing dates for winter rapeseed were studied: 1 – early, from July 10 to 31; 2 – optimal, from August 1 to 20; 3 – late, from August 20 to September 10. Weather conditions during the years of the research did not have critical deviations from the average long-term values. Rapeseed was sown at a seeding rate of 550 thousand similar seeds/ha using the usual row method with a row spacing of 15 cm. The winter rapeseed hybrid DK Exima was sown. The fertilization system provided for the application of N120P60K60 + microfertilizer Orakul colofermin boron, 3 l/ha. Other elements of the cultivation technology were generally accepted. During the growing season of winter rapeseed, the following observations and records were made: the duration of the autumn growing season in days was determined; the phases of plant growth and development at the time of the cessation of the autumn growing season; the height of the plants before the plants entered winter; the number of productive branches on one plant was counted before harvesting; the number of pods on one plant; the mass of a thousand seeds was determined by weighing; the yield of sowing was recorded using a combine harvester. It was established that the highest yield of winter rapeseed hybrid DK Exima is provided by the optimal sowing period, which falls on 1.08.-20.08. and is 3.50 t/ha. With late sowing (20.08.-10.09.) the seed yield decreases by 8.8%, and with early sowing (10.07.-31.07.) the yield of winter rapeseed is the lowest - 3.00 t/ha, which is 14.3% less. The highest yield of winter rapeseed when sown at optimal times (August 1-August 20) is ensured by the duration of the autumn vegetation period of 87 days, entering winter with 8 true leaves at a plant height of 17 cm. This ensures the formation of 8 productive branches with 431 pods on one plant with a mass of 1,000 seeds of 5.4 g.
