RESEARCH OF INNOVATIONS IN FEED PRODUCTION - PANNONICA PEAS (VICIA PANNONICA СRANTZ)

Abstract

Indicators of productivity of a mixture of Lathyrus pannonicus with Triticosecale, as an innovative product in fodder production, have been introduced. Observations have shown that in the interphase period from full sprouting-budding of Lathyrus pannonicus Triticosecale were in the phase of full earing. According to the average daily increase in green mass, a variant was noted in which 75% of Triticosecale (115.2 kg / ha) and 50% of Lathyrus pannonicus (65.2 kg / ha per day) were sown. In Lathyrus pannonicus with different sowing rates, the average daily yield increase decreased to 55.8–59.4 kg / ha against the background of N45P45K45, and for the dose of mineral fertilizers N30P30K30 it was 44.5–49.2 kg / ha. As the dominant crop of the phytocenosis, Triticosecale has the same tendency, where the growth, respectively, reached 107.0–112.8 and 95.7–101.9 kg / ha per day. It was found that option 6 dominated in the yield of green mass, which provided 46.2 and 8.77 t / ha of dry matter with a seeding rate ratio of 75: 50% against the background of mineral fertilizers N45P45K45. The increase in the yield of green mass was by 10.8 and 12.0% of dry matter for option 3 (50: 50%), as well as by 16.7 and 11.0%, respectively, compared to the background N30P30K30. Lathyrus pannonicus provided single-species sowing 17.72-21.35%. The indicators of the chemical composition of Lathyrus pannonicus changed when grown in a mixture with Triticosecale. With the maximum dose of mineral fertilizers and a ratio of seeding rates of 50: 50%, it was 20.15%, or increased by 2.79% than against the background of N30P30K30, or was lower than single-species sowing by 1.20%. Fluctuations in crude protein content between seeding rates and fertilizers were 0.16–1.11 and 2.42–3.29%, respectively. The content of crude fiber in mono-sowing of peas was 26.09–27.72%, and in binary mixtures it increased by 2.20–2.63%. Depending on the studied, the proportion of crude fiber decreased from 3.35 to 26.78%. The total percentage of crude protein in dry matter was caused by the proportion of Lathyrus pannonicus and Triticosecale in the botanical composition. With the application of mineral fertilizers in a dose of N45P45K45, the content of crude protein in var.6 was 14.69%, which is explained by the high percentage of the cereal component in the herbage and the low content of crude protein. By means of exchange experiments, the high digestibility of plant raw materials of a mixture of Triticosecale with Lathyrus pannonicus was determined.
