Effect of sulphur and nitrogen fertilisation on winter wheat in Calcaric Luvisol

Abstract

In 2019-2021, the experiment was carried out with the aim to investigate how sulphur (S) fertiliser rates under different nitrogen (N) fertiliser backgrounds influenced winter wheat grain yield, grain quality, and plant productivity indicators. The winter wheat (Triticum aestivum L.) cultivar 'Janne' was grown in four N background treatments with N 60 , N 120 , N 180 , and N 240 without S fertilisation and also fertilised with S 15 (in all N fertilisation treatments), S 30 (only with N 120 and N 240 ), and S 60 (only with N 240 ). The results showed that S fertilisation increased the wheat grain yield significantly in individual research years and only in the plots fertilised with higher N rates. N fertilisers increased the protein content, sedimentation, and gluten content of the grain, while S fertilisers only in one year and only in the N 180 fertilisation treatment. The results of experiment showed that the N:S ratio for the winter wheat at the BBCH 30 growth stage was in the range of 8-16, and at the BBCH 65 it was in the range of 9-19 indicating that the winter wheat was optimally or even more than optimally supplied with S.

Study the Effect of Nitrogen Fertilization Rates on Grain Yield and Some Physiological Characteristics of Wheat Varieties

“…Grain yield and proline content of Sakha 94 variety, RWC and Proline content of Sakha 93 variety, MDA content, SOD, CAT and ABX activities of Sids 12 variety were significantly higher than that of other varieties studied. The earlier achieved comparable results by Wang et al [3] Alam [4], Litke et al [31], Kubar et al [32] and Staugaitis et al [33]. According to Wang et al [3], with increased nitrogen application, antioxidant enzymes and grain production showed an increasing and subsequently decreasing tendency.…”

Sulfonated nitrogen and added-sulfur sources influence productivity, quality, and nutrient acquisition of soybean-wheat cropping system

“…Both N and S are essential components of the plant enzymes [ 52 ] and also have a crucial role in the synthesis of essential S-containing amino acids [ 27 , 53 ] viz . cystine, cysteine, and methionine [ 41 , 54 ].…”

“…The starch content in wheat was recorded highest with T 1 [PK & S through SSP, both crops (no-N)] due to No–N application, which indicates the inverse relationship between N concentration in plants and carbohydrate accumulation. Staugaitis et al [ 27 ], also reported that starch in grains decreased with increasing fertilizer rates. The S deficiency is known to promote the accumulation of arginine and asparagine in wheat grains which increases the risk of acrylamide formation when products of wheat flour are cooked [ 38 ].…”

“…Therefore, S management needs location-specific interventions. Besides S availability in soil, its balance with available N (N:S ratio) has a crucial role in plant metabolism, especially in protein synthesis [ 27 ]. Despite being an essential element, its application has remained sub optimal due to limited availability of S-rich customized fertilizers and limited research focusing on the optimized and standardized S doses in a cropping system mode [ 12 , 24 ].…”
