This work is devoted to the investigation of the methanogenic archaea involved in anaerobic digestion of cattle manure and maize straw on the basis of terminal restriction fragment length polymorphism (T-RFLP) analysis of archaeal 16S rRNA genes. The biological diversity and dynamics of methanogenic communities leading to anaerobic degradation of agricultural organic wastes with biogas producti...

The production of energy and biochar from the pyrolysis of straw and other agricultural residues is a developing industry that holds the potential to reduce air pollution from in-field burning, recycle nutrients, reduce chemical fertilizer inputs, and improve soil quality. Use of biochar in agriculture is undergoing tests globally. Water-soluble organic compounds from pyrolysis residue containi...

I . Using shccp fitted with re-entrant cannulas in the proximal duodenum, and which were given a ration containing long straw, a series of three experiments was conducted in which the flow of digcsta to the duodenum was measured and sampled continuously for 3 d. Therc appeared to be no consistent effect of this procedure on total flow of digesta to the duodenum from day to day, indicating that ...

In order to reduce the power consumption of screw conveyor and improve productivity, this study investigated such mechanical characteristics rubbed maize straw as coefficient sliding friction, angle repose, internal friction coefficient, cohesion, flow function value compressible with respect its moisture content density. An experiment was designed consists a characteristic test-bed, direct she...

The objective of this study was to investigate the nutritive value, in vitro dry matter degradability (IVDMD), and ensiling characteristics legume foliage–maize straw silages. For silage, proportion maize 20%:80% (maize–lablab (ML), maize–indigenous cowpea (MI), maize–Betswit (MB), maize–Dr Saunders (MD)). Maize alone (M) used as a control, making up five treatments. Silages were opened after 4...

A field experiment was conducted during 2018–19 and 2019–20 at the research farm of ICAR-Directorate Rapeseed-Mustard Research, Bharatpur, Rajasthan to evaluate effect organic inorganic nitrogen sources on yield, water productivity, system productivity economics maize (Zea mays L.)-mustard [Brassica juncea (L.) Czern.] cropping system. The in split-plot design with recommended levels fertilizer...

ABSTRACT Second-crop maize-ruzigrass (Urochloa ruziziensis) intercropping, nitrogen (N) fertilization, and high maize plant densities enhance biomass production N cycling, which may favor soybean growth yield in the following season. This study aimed to assess effects of second-crop top dressing, density on straw autumn/winter, agronomic performance crops grown succession. Field experiments wer...

ABSTRACT Determining nitrogen (N) accumulation and export by common bean as a function of straw the splitting this nutrient is very important, aiming at management sustainability agricultural systems. This study aimed to determine N Zea mays Urochloa ruziziensis grass (maize, maize/U. intercropping U. ruziziensis) top-dressing fertilization. The experiment was conducted in Jaboticabal-SP-Brazil...
