“…The increases in fresh forage yield/fed as a result of increasing nitrogen fertilizer rates up to 100 kg N/fed may be attributed to the role of nitrogen in enhancement meristematic activity and cell division, increasing the vegetative growth through enhancing leaf initiation, increment chlorophyll concentration in leaves and photosynthesis process (lawlor, 2002), consequently enhancement forage yield/fed. These results are in agreement with those reported by Ćupina et al (2011) and Anfinruda et al (2013).…”

“…While, in the case of using "(NH4)2 SO4",data show that P % and K % in the plants were significantly increased as its rate increased from 50 to 75, 100 and 125 kg N/fed in the first and the second cuttings over both seasons. These results are in line with those obtained by Anfinruda et al(2013) who reported that there was a significant response in P% with increasing nitrogen rates.…”

“…The steady increases in nitrogen percent (N%) in sudangrass plants as a result of increasing nitrogen fertilizer rates up to 125 kg N/fed may be attributed to the role of nitrogen in improving growth and dry matter accumulation as well as by the influence of nitrogen availability at critical stages on plant metabolism in a manner which leading to increase synthesis of amino acids (lawlor, 2002), and consequently enhancement nitrogen percent in forage yield of sudangrass. Beyaert and Roy (2005), Rahman et al (2008) and Anfinruda et al (2013) came to similar results.…”

AFIelD experiment was carried out at the experimental Station Farm in Giza, Agricultural Research Center, egypt, during the two successive summer seasons of 2012 and 2013. The experiment was to study the effect of varying sources, rates of nitrogen fertilizers on fresh and dry forage yields of sudangrass, chemical constituents, nitrate and nitrite accumulation in plant using a split-plot design with three replicates . The main plots were assigned to nitrogen fertilizer sources (Ammonium nitrate NH4 NO3 and ammonium sulphate (NH4)2 SO4.While, the sub-plots were occupied with rates of nitrogen fertilizer (50, 75, 100, and 125 Kg N / fed).The results indicated that the fresh and dry forage yield ton/fed, nitrogen, crude protein, phosphorus, potassium, nitrite (NO2) and nitrate (NO3)contents were significantly decreased in the second cutting as compared with the first one over both seasons. Using ammonium sulphate "(NH 4 ) 2 SO 4 " was better than using ammonium nitrate "NH4 NO3" as a source of nitrogen fertilizer over both cuttings and seasons.Fresh and dry forage yields of sudangrass were significantly increased as nitrogen rates increased from 50 to 75 and 100 kg N/fed and significantly decreased due to increasing nitrogen rate from 100 to 125 kg N/ fed over both seasons.It can be recommended that mineral fertilizing of sudangrass plants with 75100-kg N/fed is better to get suitable forage yields and reduce nitrate accumulation in plant.

“…The recent upsurge in the number of biomass studies could largely be attributable to the adoption of the Kyoto protocol in 1997 [19], which was concerned in part with the increasing greenhouse gas emissions caused by anthropological activities. Recent field studies conducted at relatively high latitudes have generally focused on the characterization of sorghum as a feedstock and on estimating the amount of producible ethanol [20][21][22]. In addition, some studies have looked at the effects of planting date and/or harvest date on sorghum biomass yield in the context of energy production [23][24][25][26].…”

Agronomic Factors Affecting the Potential of Sorghum as a Feedstock for Bioethanol Production in the Kanto Region, Japan

Abstract:In the Kanto region in Japan, the possibilities of running a bio-ethanol plant from rice straw has been assessed and sorghum production has been considered as a necessary part of the system. Two field experiments were conducted in 2012 and 2013 at the NARO-Agricultural Research Center in Tsukuba, Ibaraki to estimate yielding ability of sorghum in the Kanto region. Two cultivars of sweet sorghum and one of grain sorghum were sown using a pneumatic seeder. Above-ground dry matter (DM) yield ranged from 1.03 to 1.82 kg m −2 for the sorgo type cultivars and from 0.70 to 1.18 kg m −2 for the grain type cultivar. The observed yields were lower than the simulated potential yields, i.e., 1.61 to 2.66 kg m −2 , indicating that biomass production was restricted in this study. Stem brix values for the sweet sorghum cultivars were generally low (3.3-16.2%) compared with the values reported in the literature. It appears that there is still room to improve the field management of sorghum to minimize the gap between the potential and actual production observed in these experiments.

Agricultural practices for growing kenaf in Iowa: II. Fiber composition and quality

et al. 2020

The demand for natural fibers is increasing worldwide as markets respond to the need to replace nonrenewable sources. Kenaf (Hibiscus cannabinus L.) is a promising biorenewable resource for producing natural fibers. Few studies have investigated the crop when grown at latitudes above 40 • and in the U.S. Midwest. The objectives of this study were to assess the influence of management practices on fiber (bast and core lignocellulose) composition, carbon (C), nitrogen (N), and total ash concentration. Cultivars 'Tainung 2' and 'Whitten' were planted in Boone County, IA in 2014 and 2015 at 247,000 or 371,000 seed ha −1 , in 38-or 76-cm rows, and fertilized with N at 0, 56, 112, 168, or 224 kg ha −1 . Treatments were in a factorial design with four replications in 2 yr. Stem bast and core lignocellulose concentrations, total ash, and C/N ratio were determined at harvest. Variety or interactions of variety with management practices influenced most parameters. Increased N fertilization decreased bast cellulose concentration, but increased core cellulose concentration. Hemicellulose concentration in core was greater than in bast. Ash concentration decreased as N fertilization rate increased and interacted with seeding rate and variety. The implications of these observations are directly related to markets and desired kenaf end-use products. Variety and management interactions influence kenaf fiber quality, and consequently are important considerations for kenaf producers and processors.Abbreviations: ADF, acid detergent fiber; ADL, acid detergent lignin; DM, dry matter; NDF, neutral detergent fiber.
