Effectiveness of foliar fertilizers, applications of biologically active substances and hardening of spring wheat seeds, as affected by the method of application of basic mineral fertilizers.

摘要

Field trials investigating the use of 60:60:60 N:P:K fertilizers with crops of hard (Bezenchukskaya 139) and soft (Moskovskaya 35, Simbirka and Saratovskaya 36) spring wheat cultivated on leached chernozem in the southern Bashkir forest steppe, Russia are reported. The effect of application method (band placement or broadcasting) on crop yields was investigated for the following: foliar application of superphosphate, ammonium nitrate and urea; seed hardening; and treatments with cartolin [a cytokinin], amino salts of 2,4-D, chlorocholine chloride [chlormequat] or sodium humate. The probability of significant changes to crop yields resulting from the above treatments was approximately 2 times less for band placement than for broadcasting.
