Efficiency of liquid chelate fertilizers organomix in apple growing in the conditions of the forest zone of the KBR

摘要

Horticulture is a highly intensive industry that requires significant costs in the establishment and maintenance of plantations. The profitability of horticulture, which in the republic can reach up to 150%, depends on the use of a rational fertilization system, taking into account the biological characteristics of fruit and berry crops, the age of the garden, the phase of plant development, soil and weather conditions. Particularly high nutritional requirements are imposed by intensive early ripening varieties of fruit crops on tall rootstocks. In this work, we studied the effect of liquid chelated fertilizers Organomix when processing trees on the yield, commercial qualities of the fruit of the Florina apple tree in the conditions of the forest fruit zone of the Kabardino-Balkarian Republic. The most noticeable effect on increasing the yield of trees (27.4 t / ha) was exerted by the combined use of the preparations Organomix fruit and berry (0.5 l / ha), Organomix Bor (0.5 l / ha), Organostim (0.6 l / ha) ha) in the walnut phase. The use of the preparations contributed to an increase in the productivity of the apple tree by 16.9-32.4%. Treatment of apple trees with Organomix preparations gives high economic efficiency due to the increase in the commercial quality of the fruits.
