Title
Effect of nitrogen fertilization and microbial preparations on potato yielding
M. Kołodziejczyk Plant Soil and Environment 2014. doi:10.17221/7565-pse
Other claims from this paper (8)
- Intervention effect Nitrogen fertilization significantly increased marketable potato tuber yield
- Intervention effect Yield increments on individual fertilizer treatments ranged from 66% to 140%
- Intervention effect Growing nitrogen doses increased the number of main stems per 1 m2 from the 120 kg N/ha level
- Intervention effect Each nitrogen dose up to 180 kg N/ha markedly increased average tuber weight
- Intervention effect Microbial preparations lowered marketable potato tuber yield by 1.5 to 2.3 t/ha relative to the control
- Intervention effect Microbial preparations had an unfavourable effect on the formation of potato yield components
- Association Total potato tuber yield was significantly associated with the individual yield components
- Association Average tuber weight formation was the most visibly related yield component
