INFLUENCE OF TILLAGE AND MICROBIOLOGICAL PRODUCT ON YIELD AND QUALITY OF HEMP SEED

Abstract

The field experiment was carried out between May and September 2024. Algirdas Laurikietis' farm in Armonaičiai village, Pakruojis district municipality. The aim of the experiment was to determine the effect of tillage and microbiological products on the productivity of hemp. The hypothesis of the experiment is that minimum tillage and microbiological products do not reduce and may even increase the productivity and quality of hemp. The objectives of the experiment were: 1) to determine the effect of tillage and microbiological products on the yield of hemp seeds; 2) to determine the effect of different tillage and microbiological products on the number of mature seeds per plant of hemp seeds; and 3) to determine the effect of tillage and microbiological products on the quality of hemp seed yield. The variety of hemp grown in the study was 'CFX-2'. The field experiment was a two-factorial design: factor A - different tillage. Factor B: microbiological preparation. It was found that the application of shaving in combination with a microbiological preparation had the greatest effect on the yield of hemp seed. The latter treatment produced the highest seed yield of 1155 kg ha-1. It was found that the variants with different tillage treatments with microbiological preparation produced a lower proportion of fine hemp seeds with fractions up to 1,7 mm and 1,7 to 2,2 mm. Shaving produced the highest average number of seeds per plant, which was significantly higher (129) than tillage. Shaving alone had the highest average weight per 1000 seeds, 15,5 g, which was significantly (10,3 proc.) higher than ploughing.
