Nutrient omission plots in spring wheat in Russia: Omsk Oblast and Republic of Bashkortostan
One-season nutrient (N, P, K) omission plots were conducted on leached chernozems in agricultural enterprises' fields. Fertilizer rates were calculated for the expected grain yield of 3 t/ha based on routine soil tests. Treatments with grower fertilizer practice were also included.

Nutrient omission plots in spring wheat were conducted in 2010-2011 on leached chernozems in Omsk Oblast and the Republic of Bashkortostan. Fertilizer experiments were conducted in agricultural enterprises' fields. The following fertilizer treatments were applied: 1) control, 2) average grower fertilization practice, 3) NPK rates calculated using the balance method (based on expected wheat yield of 3 t/ha and routine soil tests), 4) NP, 5) NK, 6) PK.

Interpretive Summary
2011 | The following fertilizer treatments were applied in the Republic of Bashkortostan (N-P2O5-K2O in kg/ha): 1) control, 2) 10-10-10, 3) 150-25-28, 4) 150-25-0, 5) 150-0-28, 6) 6-25-28. Spring wheat was the third crop after fallow in this location (after winter rye and buckwheat). The highest grain yield of 3. 49 t/ha was obtained with recommended application of N, P, and K (treatment 3). N, P, and K fertilizer use increased grain yield by 0. 52 (18%), 0. 28 (9%), and 1. 09 (45%) t/ha, respectively. |
