    Notes: Summary The beneficial effect of spraying some highly active phyllosphere N2-fixing microorganisms on high and low yielding cultivars of rice plants as compared with that of urea applied at different doses are described. The dry weight, N-content, 1000 grain weight, and yield were remarkably increased in all cases with the application of phyllosphere microorganisms. The performance of two isolates KUP4 and KUPBR2 with IR-8 and IR-26 rice, was better than that of 52 kg urea-N per hectare. IR-579 rice leaves in association with some phyllosphere bacteria reduced acetylene at the rate of 664–816 nmoles/g leaf/h. In IR-26 rice the effect of application of bacterial suspension at three phases of plant growth corresponded very well with that of urea application in three split doses under identical conditions. Recommended fertilizer rates produced the same yield as the half dose plus bacterial spray in the cultivars Pankaj and Rupsail. Fertilizer application in Pankaj and Rupsail rice reduced nitrogenase activity and the beneficial effects of phyllosphere N2-fixation was reduced by 40–55%.

    Notes: Summary The utility of spraying some known N2-fixing microorganisms on rice leaves grown both in N-less sand culture and under field conditions was examined. The effect was compared with that of spraying a phyllosphere N2-fixing isolate of Klebsiella, KUPBR2, and application of nitrogenous fertilizers. All the growth parameters studied including dry weight and N-content were enhanced. Under field conditions number of tillers was increased by 26% withKlebsiella pneumoniae M5al and by 65% with Aphanothece. The dry weight of the plants was enhanced by 61–119%. The yield per 10 m2 was almost doubled with Aphanothece, Beijerinckia 8007,Mycobacterium flavum, K. pneumoniae M5al and KUPBR2. The increases observed withStreptomyces sp. G12 though less spectacular was significant at 1% level with respect to several growth parameters.K. pneumoniae M5al,M. flavum andStreptomyces sp. G12 exhibited nitrogenase activity both in laboratory culture and in association with rice plants.

    Notes: Summary Five highly active N2-fixing strains of Klebsiella isolated from the phyllosphere of tropical plants, KUPBR1, KUPBR2, KUPM, KUP4 and KUP6 along withAzotobacter vinelandii OP,A. chroococcum G40 andDerxia gumnosa were sprayed on the foliage of a high yielding wheat cultivar, Kalyansona. The strains of Klebsiella enhanced dry wt., chrorophyll and nitrogen content, and 1000 grain weight. Grain yield in inoculated plants varied between 19.9 and 25.09 quintals ha−1 against 24.34 quintals with urea. Best results were obtained with KUP4 which when applied at half dose was as effective as 52.5 kg Urea-N ha−1. Azotobacter and Derxia only slightly improved growth and nitrogen content of grain or straw.

    Description / Table of Contents: Es wird über Herstellung und Eigenschaften von NiII- und CuII-Komplexen mit der SCHIFFschen Base „BAPE“ aus Acetophenon und Äthylendiamin sowie über gemischte BAPE/Acetylaceton-Komplexe berichtet (Formeln I-V s. Abstract). BAPE wirkt dabei als zweizähniger Neutralligand. Die Komplexe wurden durch Elementaranalyse, Elektronenspektrum sowie durch magnetische und Leitfähigkeitsmessungen charakterisiert. Für MII(BAPE)Cl2 wird pseudotetraedrische, für [MII(BAPE)(acac)(H2O)2] ClO4 tetragonale Struktur abgeleitet (MII = Ni, Cu). Der Komplex [Ni(BAPE)(acac)]ClO4 erwies sich als quadratisch-planar.
    Notes: Preparation and properties of the following NiII and CuII complexes of the Schiff base derived from acetophenone and ethylenediamine (BAPE) and also of the mixed NiII and CuII chelates with BAPE and acetylacetone (acac-H) are described: In each case the Schiff base, BAPE, acts as a neutral bidentate ligand. The complexes are characterised by electronic spectra, magnetic susceptibilities, conductivities and elemental analyses. Pseudotetrahedral structure is proposed for M(BAPE)C12, while tetragonal structure for [M(BAPE)(acac)(H2O)2]ClO4 (M = Ni and Cu). The complex [Ni(BAPE) (acac)]ClO4 has been found to be square planar.
