    Notes: Abstract Conversion of sawdust, a major waste generated by the timber industry, to an agricultural supplement was explored. Beds made with a mixture of Eucalyptus sawdust and soil reduced the chlorophyll content and the growth rate of wheat seedlings. However, following treatment with Volvariella volvaceae and urea, the sawdust in growth beds enhanced both the chlorophyll content and growth of wheat seedlings. Application of treated sawdust to soil increased the biomass of both bulb and foliage of onion. This represents a small beginning in the conversion of an industrial solid waste into a soil conditioner for enhancing agricultural productivity.

    Notes: Abstract Arylmercury(II) derivatives of kojic acid and maltol of the typep-XC6H4HgL1 (I) andp-XC6H4HgL2 (II) [HL 1=kojic acid,HL 2=maltol;X=M, MO, NO2] have been synthesised. IR spectral studies indicate that both the ligands act as bidentate groups, bonding to the mercury(II) ion through phenolic and carbonyl oxygens. From TG curves, the order and activation energy of the thermal decomposition reaction have been elucidated. The variation of the activation energy has been correlated with the nature of the substituents on the phenyl ring. The heat of reaction has been elucidated from differential scanning calorimetric studies. The fragmentation pattern has been analysed on the basis of mass spectra.
