“…The applied S did not increase the number of fertile tillers at maturity. This was consistent with the results obtained under field conditions (Hussain and Leitch, 2007), where application of S at tillering produced similar results. The results were, however, in contrast to other findings (Garcia Del Morel and Ramos, 1987) that displayed augmented number of barley ears following S application at tillering.…”

“…Other investigators (Jensen and Andersen, 1981;Hill et al, 1982;Kettlewell et al, 1983;Stokes et al, 1985) described contradictory reports, in terms of the stage of growth at which a plant growth regulator is administered, as it modifies tillering, growth, and development. Though in the current investigation, foliar S (20 kg/ha), at stem extension apparently reduced stem length, the effect was statistically non-significant; which was in contrast to that being recorded under field conditions (Hussain and Leitch, 2007) where applied S, similar to CC, at stem extension, significantly reduced the stem length and increased the unit stem weight. These antagonistic results might have occurred because a high dose of N (200 kg/ha) was administered to the crop under field conditions; which was not the case in this investigation.…”

“…Foliar S application to barley displayed similar increase in yield as with ethrel (Garcia Del Morel et al,1999) and ethephon (Ramos et al,1989); which was primarily caused by increased tillering in treated plants. In another study (Hussain and Leitch, 2007), foliar S application at stem extension (GS30 or GS32) in the wheat, grown in field conditions, did not augment grain yield (apparently, as lodging did not occur); nevertheless, the average stem length was retarded and the unit stem weight increased, though these effects were not to the same magnitude as that obtained with the CC application. Investigations, testing foliar S as a growth regulator in cereals, are rare, hence the current work, where foliar S application, at GS23, GS30 and GS32 in the wheat crop grown in glasshouse conditions, was tested and compared with CC and GA 3 , in terms of its growth regulatory effects alongside its impact upon N-uptake.…”

During the year 1999, two glasshouse experiments (Experiments 1 and 2) were conducted at the University of Wales Aberystwyth, UK to investigate the effects of foliar applied sulfur (S) in wheat in terms of its potential as a growth regulator and to compare the effects with that of commercial growth regulators, chlormequat (CC) and gibberellic acid (GA 3 ). In Experiment 1, the grain yield was unaffected by sulfur or growth regulator treatments. Similarly, there were no differences in the number of fertile ears at maturity. Stem characteristics were not affected with S application, but CC application reduced the average stem length; although, it did not affect the unit stem weight. The GA 3 did not change stem characteristics. In Experiment 2, the grain yield was significantly reduced by CC. Stem characteristics were not affected by S application while application of CC brought about a significant reduction in the stem length and increased the unit stem weight. Applied CC reduced the stem length irrespective of the timing of its application, maintaining its versatility as a growth regulator. Grain Nitrogen (N) concentration was apparently increased; while in Experiment 2 plant N-uptake occurred significantly by foliar S application at 20 kg/ha. The work emphasized the potential role of S in a lowinput wheat production system or in organic wheat production systems.

“…1000 grain weight (g): Applications of N and S levels and interaction between N & S did not significantly affect the 1000 grain weight. These results are in conformity with those obtained by other researchers (Hussain & Leitch, 2005, 2007, 2008 who did not observe an increase in 1000 grain weight when N or S was applied to the wheat crop. It was observed by Ramos et al (1989) ) at sowing and anthesis also appeared to increase the number of grains spike -1 .…”

“…Khan et al (2003), reported that S application at 20 kg ha -1 increased the number of spikes m -2 and number of grains spike -1 . It was reported by Hussain and Leitch (2007) that application of S (20 kg ha -1 ) at stem extension in the wheat crop increased the number of productive tillers at maturity. Other researchers (Garcia Del Morel and Ramos, 1987) showed that application of elemental S in barley at tillering increased the number of spikes.…”

The effects of sulphur (S) and nitrogen (N) on the growth, yield and quality of wheat were studied at The University of Agriculture, Peshawar during the year 2009-10. Randomized complete block design (RCBD) in split plot arrangement with N rates as main plot factor i.e., optimum N at sowing: 120 kg ha -1 , excessive N at sowing: 200 kg ha -1 , optimum split N at sowing and anthesis: 60-60 kg ha -1 , excessive split N at sowing and anthesis: 100,100 kg ha -1 and Soil and foliar applied S as subplot factor i.e., Untreated/control, soil S at stem extension: 20 kg ha -1 , foliar S at stem extension: 20 kg ha -1 , soil S at anthesis: 20 kg ha -1 , foliar S at anthesis: 20 kg ha -1 , foliar S at Stem extension and anthesis: 10,10 kg ha -1 were used. S application at stem extension (20 kg ha -1 ) either applied to soil or foliage of the crop caused greater grain yields irrespective of the dose of N application (optimum or excessive). The increased grain yields appeared to be the result of a higher number of spikes produced due to applied foliar S (20 kg ha -1 ) at stem extension or then it may be the result of a higher leaf area produced due to S (20 kg ha -1 ) application to the soil at stem extension. Sulphur at 20 kg ha -1 should be applied to the wheat crop at stem extension, either as foliar spray or to the soil alongside applications of an optimum dose of N, i.e., 120 kg ha -1 in order to improve both the quantity and quality of the produce.
