The survey was conducted during 2006-2008 year in experimental field of the Maize Research institute – Kneja the following three-field rotation, grain maize, spring three wheat.
Tested the impact of levels of mineral fertilizes: N16P11K11 kg/da and N32P22K22 kg/da and one don’t fertilizing control N0P0K0 kg/da on the productivity of rotation.
Found that compared with don’t fertilizing control, fertilization N16P11K11 kg/da increases the yield of grain and energy ant 24,42% and 23,77%, and twice N32P22K22 kg/da with 38,87% and 30,16%.
Effect of 1 kg mineral fertilizes in receipt of 36,62 Mj unit for N16P11K11 kg/da and 8,77 Mj for twice the rate of fertilizing N32P22K22 kg/da.
