AGRONOMIC AND TECHNICAL EFFICIENCY OF THE PRODUCTIVITY OF OILSEED RAPE FROM COMBINATIONS OF SEVERAL NUTRIENTS

Abstract

The increase in yield per unit area in kg and the attained outcome from the usage of certain amounts of nutrients are measured by agronomic efficiency (AE). In terms of the sensible use of nutrients, the capacity and to determine technical efficiency is a contribution to this research. The findings are intended to aid in determining the efficacy of using the most essential nutrients (N, P₂O₅, K₂O, S and B) to determine their impact on productivity capacity. The purpose was to evaluate how varied levels of nitrogen, sulfur, and boron affected on potential of winter oilseed rape. For N was using quantities of 100 and 150 kg ha^-1, for S 30 and 70 kg ha^{- 1}; and B 1 and 2 kg B ha-1. N (50 kg ha^-1) P and K (90 and 180 kg ha^-1) was also applied before sowing. The research was performed in vegetation years 2016 - 2018, with two genotypes: variety and hybrid, in 15 variants and 4 replications: 1: control 50 N kg ha^{- 1}; 2: 100 N kg ha^{- 1}; 3: 150 N kg ha^{- 1}; 4: 130 N+S kg ha^{- 1}; 5: 170 N+S kg ha^{- 1}; 6: 180 N+S kg ha^{- 1}; 7: 220 N+S kg ha^{- 1}; 8: 131 N+S+B kg ha^{- 1}; 9: 132 N+S+B kg ha^{- 1}; 10: 171 N+S+B kg ha^{- 1}; 11: 172 N+S+B kg ha^{- 1}; 12: 181 N+S+B kg ha^{- 1}; 13: 182 N+S+B kg ha^{- 1}; 14: 221 N+S+B kg ha^{- 1} и 15: 222 N+S+B kg ha^{- 1}. The average agronomic efficiency of all variants was 4.66 kg for the variety and 2.99 kg for the hybrid. Technical efficiency showed constant efficiency in three variants, and increase tendency to other.
