Sulphur nutrition index in relation to nitrogen uptake and quality of winter wheat grain

Popis výsledku v původním jazyce

A sulphur nutrition index (SNI) is an analogue of the N nutrition index, which is a widely used simple indicator of plant N status. The aim of this study was to relate the SNI (ratio of S concentration in shoot biomass to critical S concentration - Sc) to N uptake, grain yield and breadmaking quality of winter wheat (Triticum aestivum L.) grain during 4-yr small-plot field experiments realized under non-limiting N conditions in three different locations in the Czech Republic. The model of S dilution curve (Sc) developed by Reussi et al. (2012) for spring wheat was used for expression of the SNI. According to the model, optimal S concentration in shoot biomass was calculated using nothing but shoot biomass weight. The constant value of Sc = 0,55 was determined for shoot biomass weight lower than 1,0 t ha-1. A very strong correlation was recorded between the SNI and an N to S weight ratio (N:S) in shoot biomass. Correlation between the SNI and relative grain yield was weak.
