Productivity and economical appraisal of growing raspberry according to substrate for mulching under the conditions of podilia area in Ukraine

Based on studies of substrates for mulching raspberry varieties Veresnevi zori revealed the following: for mulching with straw or sawdust, the onset of the phenological phases of raspberry plants occurs later, compared to the cultivation without mulching; a greater number of root shoots and shoots are provided by growing raspberries without mulching, but a higher shoot height (133.2 cm) and shoot shoots (123.9 cm) distinguishes the straw mulch variant; the maximum yield of raspberry berries of the Veresnevi zori variety is provided by mulching with sawdust - 94.5 c/ha, which is 3.1 c/ha more than straw mulching and by 16.9 c/ha the control variant. The share of ripe berries in the yield by mulching sawdust increases to 81.5%, which is 4.4% more compared to straw mulching and 9.1% more compared to the control variant; the highest average weight of berries and maximum weight of 5 berries was obtained by mulching raspberries with sawdust; for raspberry mulching with sawdust, the profitability of raspberry berries production is the highest -258.9% and 4.3% less than straw mulching. The results of the work are recommended to be used during research and in practice.
