INFLUENCE OF SOWING TIME ON YIELD AND PROTEIN YIELD OF BREEDING SAMPLES OF PEA

The objective of the research is to identify the optimal sowing dates for evaluating pea breeding samples in terms of yield, protein content and yield. The objects of study were five samples of peas. The tasks were to analyze the change in the yield of different morphotypes of peas under early and late sowing dates; determine and compare the protein content for the studied breeding samples at different sowing dates; compare protein yield per unit area at early and late sowing dates. It was found that in terms of yield, the samples of the first sowing period exceeded the yield of ones of the second period, while there was no significant difference in the protein content in the seeds, but the protein yield at the first sowing term exceeded the protein yield at the second term.
