“…These results indicate that N input of 90-120 kg N ha -1 is sufficient to obtain maximum grain and sugar yields, while the further application of N fertilizer poses a risk of having negative effects on sweet sorghum production. Turgut et al 30 observed similar results and reported that the yield of sweet sorghum increased at up to 100 kg N ha -1 , but decreased when 200 kg N ha -1 was applied under a Mediterranean-type climate in the coastal region of Turkey. Sumantri & Lestari 28 also reported that the millable stalk yield of sweet sorghum increased at up to 90 kg N ha -1 but not from 90 to 120 kg N ha -1 .…”

“…In contrast, relatively few studies have been made regarding the effects of N on sweet sorghum productivity. Turgut et al 30 investigated the optimum N input for maximizing sweet sorghum yield in a clay loam soil in coastal regions. Reddy et al 19 also studied the effects of N input on sweet sorghum growth in Vertisols (Pellic Vertisol, FAO classification 7 ; Typic Pellustert, USDA classification 27 ).…”

“…Nitrogen recommendation vary with expected yield, soil properties, cultivars and cropping sequence (Wiedenfeld, 1984;Turgut et al, 2005;Almodares et al, 2007;Wortmann et al, 2010;Miri and Rana, 2012). In general, N requirement of sweet sorghum is less than that of other alternative biofuel crops such as sugarcane and maize (Anderson et al, 1995).…”

ABSTRACTwas also significantly higher than that from NTJ 2 (US$ 415 ha -1 ) and ICSV 93046 (US$ 539 ha -1 ). All cultivars responded to applied N up to 150 kg ha -1 ; however beyond 90 kg ha -1 N rate, the increase in yield was insignificant. Estimated N use efficiency (NUE) values indicated that 90 kg N ha -1 was an optimum N level for sweet sorghum crop. Simulated soil water balance components revealed that reduction in total transpiration due to water stress was 20 to 45% compared to the no-stress. In case of water use efficiency, CSH 22 SS showed the highest economic returns per unit volume of water input. Based on these results, it is concluded that sweet sorghum hybrid CSH 22 SS at 90 kg N ha -1 is the best remunerative combination for maximizing yield, economic returns and resource use efficiency.

“…Among them, nitrogen is the most important nutrient element as this crop responds well to N fertilization [20]. Turgut et al [21] investigated the optimum N input for maximizing sweet sorghum yield in a clay loam soil. Reddy et al [22] also studied the effects of N input on sweet sorghum growth.…”

“…In addition, Olugbemi and Ababyomi [27] examined different treatment of nitrogen fertilizer on the growth and ethanol yield of four sweet sorghum varieties and found that the application of 120 kg N/ha was the best for ethanol production. There are also several research studies on optimizing the nitrogen requirements of sweet sorghum for various environments and soil types [20][21]. The applied doses on sugarcane were important on the yield and ethanol production in Brazil [28].…”

Sweet sorghum (Sorghum bicolor) is a promising alternative crop for bioethanol production in developing countries. However, to extend the cultivative area of this crop, it needs to develop an appropriate growing protocol for farmers. This chapter describes the examination of different doses of fertilizers combined with manure and micronutrients, in various applied times, on biomass, sugar content and ethanol production of sweet sorghum. It was observed that the application of 90 N + 90 P 2 O 5 + 60 K 2 O provided maximum stem yield and optimum contents of sugar and ethanol yield, however nontreatment of any among P, P 2 O 5 and K 2 O caused significant reduction of biomass and ethanol production. Higher fertilization >90 N may provide greater productivity of this crop but it may cause lodging and economic deficit for farmers in developing countries. It was also found that the applied times of fertilization should be at 3-4 to 7-8 leaf stage. In contrast, when the fertilization was as close to the flowering stage caused remarkable reduction of stem yield and ethanol production. The supplementation of (NH4) 2 MO 7 O 2 .4H 2 O at 5 kg/ha provided an increase of 10-12 tons/ha of stem yield and a remarkable enrichment of ethanol production. Findings of this study are useful for farmers and agricultural extensionists to promote biomass and ethanol productivity of this crop for bioethanol production. This research also highlights a greater possibility of exploiting sweet sorghum cultivation in infertile and hilly, abandoned areas for ethanol production.
