Influence of different methods of application of effective microorganisms in nutrition of wheat on weight by 1000 grains, yield, and content of crude wheat proteins (Triticum SP)

Abstract

The research was carried out in three vegetative seasons 2015/16, 2016/17, and 2018/19, on an experimental plot in Padinska Skela, Belgrade, Serbia. The supplement included four NPK treatments (kg ha−1) and foliar treatment with effective microorganisms (EM 7 l ha−1) T1-129: 60: 60; T2-129: 60: 60 + 1 EM; T3-106: 60: 60 + 2 EM ; T4-83: 60: 60 + 3 EM. Four wheat genotypes were sown (Ratarica, Pobeda, Nogal, and Apache). Thousand grain weight and grain yield were determined. The thousand grain weight (TGW) was in the variety Pobeda 43.73 g, and the highest grain yield was in the variety Ratarica 7.02 tha−1. Both varieties are medium late, bread varieties. The treatments have different effects on the studied variables. The TGW was the highest in the T2 treatment of 40.81 g and the grain yield in T3 of 6.62 t ha−1, which was at the level of statistical significance of p > 0.01. The crude protein content was highest in the treatment of T2 13.93% (p > 0.01).
