Sunflower is an important crop cultivated all over world owing to its versatile nature of adaptation to different agro-climatic and soil conditions. In India sunflower gains momentum as an edible oil and ranks fourth substantially by reducing the shortage of vegetable oil. Nutritionally sunflower oil benefits human due to presence of high linoleic acid content and absence of linolenic acid content. The productivity is lower due to different factors among which nutrient management especially sulphur that plays pivot role in governing the growth, yield and quality of sunflower. Sulphur contains aminoacids viz., cystein, methionine, cystine, vitamins B, biotin and thiamine. The protolytic enzymes aids in improving the oil content, protein content and quality of seeds by sulphur supplement. Extensive investigations of research scientist on sulphur levels were critically reviewed. Application of sulphur at 40 to 60 kg ha-1 was found to increase the growth and yield attributes, yield, quality as well as higher benefit cost ratio sustaining the livelihood of sunflower growers.
Sunflower being an oilseed is cultivated all over the world owing to its wide adaptability to different soil and climatic conditions, photo-thermo-insensitiveness, tolerance to drought and early maturity Kalaiyarasan et al., (2016). Sunflower ranks fourth among oilseed crops in India contributing major role in edible oil and consumption purpose. The contribution of sunflower oil for achieving self-sufficiency in edible oil production and yellow revolution was remarkable in India although it is an recent origin dating back to three decades only. The sunflower oil gains priority due to its higher poly unsaturated fatty acid in addition with high linoleic acid content and lack of linolenic acid content. Sunflower seed has 48-53% edible oil and contains 64% of linoleic acid which is considered good to heart patients. Sunflower oilcake serves as an high quality cattle as well poultry feed because of its high protein content and also organic manure for crop production Taha (2015). Among the different reasons nutrient management especially sulphur deficiency is remarkable. Sulphur is recognized as the fourth major nutrient next to nitrogen, phosphorus and potassium. Sulphur aids in the synthesis of sulphur containing aminoacids such as cystein, methionine and chlorophyll, vitamins B, biotin and thiamine. It is also involved in the metabolism of carbohydrates, oil content, protein content and in addition on growth and metabolism, es­pecially by its profound effect on protolytic enzymes Najar et al., (2011). Lack of organic source of nutrient supplement, intensive cultivation, high nutrient exhausting nature of hybrids and repeated use of high analysis straight fertilizers without sulphur led to sulphur deficiency in the present hour. The sulphur plays a predominant role in determining the quality of grain, sunflower oil and also improves the nutrient use efficiency of nitrogen, phosphorus and potassium. The positive trend with regard to sulphur application on growth parameters, yield attributes, yield, nutrient uptake, quality and economics in sunflower from investigations of eminent research scientist have been cited in the review paper.
 
Effect of sulphur application on growth and growth parameters of sunflower
 
Reddy and Singh (1996) reported that sulphur application at 40 kg ha-1 significantly increased the plant height, leaf area and dry matter production of sunflower compared to control.Plant height and leaf area index was maximum with application of 45 kg ha-1 of sulphur in sunflower (Singh et al., 2000). Ali et al., (2000) divulged that sulphur application at 30 kg ha-1 maximum leaf area in sunflower from his study. Poonia (2000) reported that sulphur application at 25 kg ha-1 gave significant increase in plant height and dry matter yield compared to control in sunflower. Awasthi et al., (2001) concluded that increasing levels of application of nitrogen, sulphur and boron gave a significant increase in height of plant, stem girth and dry matter production of sunflower. Budhar et al., (2003) concluded that sulphur application increased dry matter production compared to no application in sunflower. Application of sulphur at 40 kg ha-1 gave maximum plant height, leaf area index and dry matter production in sunflower Bhagat et al., (2003). Poonkodi and Poomurugesan (2005) found that sulphur application at 60 kg ha-1 gave maximum plant height (137.87 cm) and dry matter production (4490.52 kg ha-1) of sunflower. Application of 45 kg ha-1 of sulphur gave a significant increase in the dry matter yield of sunflower Poonkodi and Kalpana (2005). Khan et al., (2007) revealed that sulphur application through sulphide materials (SM) at 75 kg ha-1 enhanced leaf area index of sunflower. Leaf area index, 50% flowering and crop growth rate were significantly increased with sulphur application at 60 kg ha-1 in sunflower Sarkar and Mallick (2009). Kale and Adsule (2009) obtained a significant increase in dry matter yield of sunflower with application of sulphur at 30 kg ha-1.

Hussain et al., (2011) concluded that 60 kg ha-1 of sulphur application significantly increased the seed yield of sunflower. Patra et al., (2013) stated that stimulated photosynthetic activity and synthesis of protein due to sulphur application gave significant improvement in seed yield and biological yield of sunflower crop.Seed yield was 8.85% higher with 60 kg ha-1 of sulphur application than 30 kg ha-1 in sunflower (Faisul-ur-Rasool et al., 2013). Tahirl et al., (2014) found that sulphur application at optimum levels had positive impact on seed yield and maximum seed yield of 814.7 kg ha-1 was obtained in sunflower. Vala et al., (2014) documented higher seed yield (1077 kg ha-1) with application of sulphur at 40 kg ha-1 through gypsum over control (647 kg ha-1) in sunflower. Sheoran et al., (2014) concluded application of sulphur at the range of 32.99 to 38.95 kg ha-1 is enough to attain economic optimum yield of sunflower. Application of 75 kg ha-1 of sulphur gave maximum seed yield (2335.6 kg ha-1) compared to control (1932.8 kg ha-1) in sunflower Rana et al., (2015). Seed yield was maximum (1060 kg ha-1) with sulphur application at 45 kg ha-1 compared to no application (1072 kg ha-1) in sunflower (Ravikumar et al., 2016).Sulphur application at 40 kg ha-1 recorded maximum seed yield (2178 and 2278 kg ha-1) and stalk yield (4422 and 4483 kg ha-1) than other levels and control in both crops Kalaiyarasan et al., (2016).  (Kalaiyarasan et al., 2020) reported that sulphur application at 60 kg ha-1 gave higher seed yield (2115.59 and 2215.95 kg ha-1) and stalk yield  (4180.03 and 4273.20 kg ha-1) in both crops respectively compared to no application.Seed yield was higher with sulphur application at 50 kg ha-1 (1476. 71 kg ha-1) compared to control (1035.01 kg ha-1) Indu and Singh (2020)
 
Effect of sulphur application on nutrient uptake of sunflower
 
Raju (1994) noticed that uptake of sulphur was higher with  application of sulphur at 40 kg ha-1 than control in sunflower. Agarwal and Verma (1998) found that N, P and S uptake were significantly higher up to 60 kg ha-1 of sulphur application in sunflower. Thorat et al., (2003) stated that sulphur application increases the uptake of other macronutrients compared to control treatment in sunflower. Application of sulphur at 60 kg ha-1 significantly increased the uptake of nutrients in seeds viz., nitrogen (40.56 kg ha-1), phosphorus(3.36 kg ha-1), potassium (56.90 kg ha-1) and sulphur (4.70 kg ha-1) over control (23.79, 1.93, 31.92 and 2.35kg ha-1) respectively. Similar increased uptake of nutrients were recorded in stalk viz., nitrogen (14.97kg ha-1) phosphorus (6.01kg ha-1), potassium (45.50 kg ha-1) and sulphur (6.51kg ha-1) against no application (10.80, 3.93, 30.18 and 4.20kg ha-1) respectively in sunflower Shubhangi et al., (2008). (Ravikumar et al., 2016) registered a significant increase in nutrient uptake of nitrogen (82.16, 85.80 kg ha-1), phosphorous (14.94, 14.97 kg ha-1), potassium (113.63, 113.80 kg ha-1) and sulphur (11.68, 12.00 kg ha-1) with elemental sulphur at 45 kg ha-1 along with recommended dose of fertilizers (40:20:20) than lower levels and control in both seasons. Gandhi (2011) found that nitrogen phosphorus, potassium, sulphur uptake was significantly higher with sulphur application at 40 than other levels and no application in sunflower. Venkadesan (2016) reported that nitrogen phosphorus, potassium and sulphur uptake was higher with sulphur application at 40 compared to other levels and control in sunflower. Abilash (2017) found an significantly increase in uptake of  N, P, K and S  by leaves, stalks, seeds and total uptake at various growth stages with sulphur application at 45 kg ha-1 compared to lower levels in sunflower. Kalaiyarasan et al., (2020) documented that nitrogen, phosphorus, potassium and sulphur uptake was higher with sulphur application at 60 kg ha-1 of sulphur over other levels and control in sunflower.  
 
Effect of sulphur application on quality of sunflower
 
Gangadhara et al., (1990) reported that sulphur application increased the oil content to 4 per cent over control in sunflower. Ghosh (2000) stated 60 to 80 kg ha-1 as optimum dose of sulphur for attaining higher oil yield in sunflower. Protein content of sunflower was significantly higher with sulphur application at increasing levels more than 50 kg ha-1 Walia et al., (2001).(Kadar et al., 2001) revealed that increasing levels of sulphur gave a decrease in oil contents of seeds from 50% to 45% in sunflower crop. Oil yield was significantly increased with sulphur application up to 50 kg ha-1 in sunflower Kumar et al., (2002). Singh et al., (2002) noticed that sulphur application at 45 kg ha-1 significantly increased the protein content, oil content and oil yield of sunflower. Dubey and Khan (2003) stated that application of sulphurupto 40 kg ha-1 gave a significant increase in  oil content as well as oil yield of sunflower. Naik and Rao (2004) documented higher oil content of 40.8% in sunflower with sulphur application at 40 kg ha-1. Sulphur application at 20 kg ha-1 registered significant increase in  the oil content (44.6%) and protein content (18.4%) in sunflower over control Mohapatra and Chandrajee (2005). Kumar and Singh (2005) found an significant increase in oil content of sunflower with increasing dose of sulphur application of 30 kg ha-1. Bakht et al., (2006) reported that higher oil production due to its high oil contents in seed by application of sulphur. Ganapathy et al., (2006) reported a significant increase in oil content in sunflower with sulphurapplication. Karthikeyan and Shukla (2008) obtained a significant increase in oil content and protein content of sunflower with sulphur application at 60 kg ha-1. Rani et al., (2009) found that oil yield increased to the tune of about 23 per cent with sulphur application at 60 kg ha-1 over control in sunflower. Tamak et al., (2010) noticed that oil content and protein content was significantly increased with sulphur application at 50 kg ha-1 than 25 kg ha-1 and control in sunflower. Oil yield was found to be statistically higher with sulphur application at 60 kg  ha-1 in sunflower Hussain et al., (2011). Patra et al., (2013) stated that sulphur application enhances the oil content of sunflower. Lal et al., (2013) observed that sulphur application resulted in maximum oil content (40.26%) over no application. Oil yield was higher (1.00 t ha) with 60 kg ha-1 compared to 30 kg ha-1 (0.88 t ha) of sulphur application (Faisul-ur-Rasool et al., 2013). Oil yield was higher (373.72 kg ha-1) with 40 kg ha-1 of sulphur application compared to control (197.34 kg ha-1) in sunflower Vala et al., (2014). Significant increase in oil yield (980.2 kg ha-1) was documented with sulphur application at 75 kg ha-1 compared to no application (730.1 kg ha-1) in sunflower Rana et al., (2015). (Ravikumar et al., 2016) reported that application of sulphur at 45 kg ha-1 through elemental sulphur gave significant increase in oil content (38.54%, 38.51%) and crude protein content (16.39%, 16.35%) compared to control (37.04%, 37.11%) and (15.02%, 15.09%) respectively, than lower levels and control in two season. Venkadesan (2016) found that application of sulphur at 40 kg ha-1 registered higher oil yield over control and other levels in sunflower. Sulphur application at 45 kg ha-1 registered significant increase in oil content (38.23%), oil yield (657.75 kg ha-1), protein content (17.08%) and protein yield (294.23 kg ha-1) over lower levels in sunflower Abilash (2017). Indu and Singh (2020) concluded that application of sulphur at 50 kg ha-1 along with 0.2% foliar spray boron gave significant increase in oil content (45.7%) compared to control (35.17%) in sunflower crop. Kalaiyarasan et al., (2020) registered highest oil content (40.68% and 41.65%) with application of sulphur at 60 kg ha-1 over control treatment (37.67% and 38.19%) in first and second crop respectively. Similarly crude protein content was significantly higher (27.31% and 29.36%) than no application (23.76% and 24.51%) in sunflower. 
 
Effect of sulphur application on economics of sunflower
