Water Use Efficiency and Evapotranspiration of Hybrid Napier (\u3cem\u3ePennisetum purpureum\u3c/em\u3e x \u3cem\u3eP. americanum\u3c/em\u3e) under Semi-Arid Indian Region
Napier bajra hybrid (Pennisetum glaucum x P. purpureum) is a highly valued for its abundant quality forage, round the year fodder availability, regenerative ability and suitability to silage and hay making. It yields upto 110-120 t/ha fresh fodder as sole crop. Though, it requires moist regimes for optimum growth, but it can withstand drought for a short spell and regenerate with rains. It contains 8.7-10.2 % crude protein, 28-30.5% crude fibre and 10-11.5 % ash on dry matter basis (Agrawal et al., 2001). The hybrid napier has wider adaptability and is grown all over the country, particularly in milk shed area of Gujrat, Maharashtra and north and central India.
Estimation of evapotranspiration (ET) as a function of crop stages is important in determining crop water use for efficient irrigation management. Evapotranspiration loss and the rate of evapotranspiration at different cutting stages indicate the amount of water required at different growth periods for its satisfactory growth and optimum production. Few results in measurement of evapotranspiration and water use efficiency of fodder crops are available (Alvarez and Quiroga, 1992; Pradeep Behari et al., 2003). The water stress in the plant can be quantified by actual evapotranspiration rate, as the level of evapotranspiration is related to the evaporative demand of the air (Doorenbos and Kassam, 1979). However, the information on these aspects for hybrid napier is lacking. In present study we estimate, the water use efficiency and evapotranspiration of the hybrid napier in central India
Microbial beta glucosidase enzymes: recent advances in biomass conversation for biofuels application
The biomass to biofuels production process is green, sustainable, and an advanced technique to resolve the current environmental issues generated from fossil fuels. The production of biofuels from biomass is an enzyme mediated process, wherein β-glucosidase (BGL) enzymes play a key role in biomass hydrolysis by producing monomeric sugars from cellulose-based oligosaccharides. However, the production and availability of these enzymes realize their major role to increase the overall production cost of biomass to biofuels production technology. Therefore, the present review is focused on evaluating the production and efficiency of β-glucosidase enzymes in the bioconversion of cellulosic biomass for biofuel production at an industrial scale, providing its mechanism and classification. The application of BGL enzymes in the biomass conversion process has been discussed along with the recent developments and existing issues. Moreover, the production and development of microbial BGL enzymes have been explained in detail, along with the recent advancements made in the field. Finally, current hurdles and future suggestions have been provided for the future developments. This review is likely to set a benchmark in the area of cost effective BGL enzyme production, specifically in the biorefinery area
Degradability of cross-linked polyurethanes/chitosan composites
Polyurethanes with synthetic poly([R,S]-3-hydroxybutyrate) in the soft segment and with polycaprolactone triol as cross-linker were blended with chitosan and degraded in hydrolytic and oxidative solutions. Progress of the degradation of the samples was evaluated by changes in their weight, surface topography and thermal properties. Increasing the poly([R,S]-3-hydroxybutyrate) content in soft segment as well as blending with chitosan resulted in an increase in degradability of cross-linked polyurethanes in both solutions.Centre of Polymer and Carbon Materials, Polish Academy of Sciences, University of Wolverhampton, University of the Basque Country (UPV/EHU), Gdynia Maritime Universit
