Effect of zinc microelement on productivity of unabi plant and its fruit quality against macrofertilizers in gray-brown soils of Absheron
Summary
On the gray-brown soils of Absheron, studies were carried out using various doses of the trace element zinc against the background of macrofertilizers on the yield and quality of unabi fruits. The results of laboratory analyzes showed that the gray-brown soils of Absheron are poorly provided with assimilable forms of nitrogen, phosphorus and trace elements zinc and medium potassium. The trace element zinc was introduced under the culture of unabi against the background of N100P40K70 in 3 doses. The research results showed that the highest increase in yield (3.8 c / ha or 13.3%) and fruit quality (vitamin C 670 mg /%, sugar 33.0%, acidity 0.58% and the content of trace elements: Cu- 18.5- Zn-40.0 mg / kg) of the unabi plant is observed in the variant with the introduction of zinc at the rate of 2.0 kg per hectare.
