    Notes: Summary Chickpea cultivars (Cicer arietinum L.) and their symbiosis with specific strains of Rhizobium spp. were examined under salt stress. The growth of rhizobia declined with NaCl concentrations increasing from 0.01 to 2% (w : v). Two Rhizobium spp. strains (F-75 and KG 31) tolerated 1.5% NaCl. Of the 10 chickpea cultivars examined, only three (Pusa 312, Pusa 212, and Pusa 240) germinated at 1.5% NaCl. The chickpea — Rhizobium spp. symbiosis was examined in the field, with soil varying in salinity from electrical conductivity (EC) 4.5 to EC 5.2 dSm-1, to identify combinations giving satisfactory yields. Significant interactions between strains and cultivars caused differential yields of nodules, dry matter, and grain. Four chickpea — Rhizobium spp. combinations, Pusa 240 and F-75 (660 kg ha-1), Pusa 240 and IC 76 (440 kg ha-1), Pusa 240 and KG 31 (390 kg ha-1), and Pusa 312 and KG 31 (380 kg ha-1), produced significantly higher grain yields in saline soil.

    Notes: Abstract Seventeen strains of Rhizobium leguminosarum biovar viceae specific to the lentil (Lens culinaris L.) were screened, using the high-yielding lentil cultivar L 4076, for their tolerance to three levels of NO3 –: 0, 4, and 8 mM NO3 –. Preliminary screening of this symbiosis for nodulation and N fixation in the presence of NO3 – showed significant variations among the strains. The number of nodules decreased and nitrogenase activity was depressed in all strains in the presence of NO3 –. Strains L-1-87, L-27-89, L-33-89, and L-40-89 tolerated 8 mM NO3 –. Four strains, three tolerant of NO3 – (L-1-87, L-27-89, and L-33-89), and one sensitive (L-11-89) to NO3 –, were selected from preliminary screening and used in a pot experiment to assess the symbiosis in the presence of 6 mM NO3 – at three stages of plant growth, viz., 40 days, 60 days, and at the final harvest. In general, the weight of nodules and C2H2 reduction activity was significantly higher after 60 days than after 40 days. Inoculation with strain L-1-87 produced the maximum number of nodules, and root and shoot biomass both in the presence and the absence of NO3 –. Nitrate reductase activity in the tops and nodules was assayed only after 60 days and did not show significant variations among strains and NO3 – treatments. The grain yields for all strains except L-11-89 were significantly higher in the presence of NO3 – than in the absence of NO3 –, indicating that tolerant strains contributed symbiotically fixed N to the plant‘s N pool, resulting in an additive effect on yield. Inoculation with strain L-1-87 produced the maximum grain yield and this strain appears to have potential use as an inoculant in the presence of high levels of soil N.

    Notes: Abstract Bradyrhizobium sp. (Vigna) strain S24 interacted differentially with eight vesicular-arbuscular mycorrhizal (VAM) fungi and caused significant variations in nodulation and growth parameters of green gram. Coinoculation with Scutellospora calospora resulted in the highest nitrogenase activity and dry biomass. The nodulation competitiveness of strain S24 was significantly higher (60–63%) in the presence of Glomus mosseae, G. fasciculatum and Scutellospora calospora when compared to treatment with single inoculation of S24 (51%). Percentage VAM colonization was higher in treatments having higher nocule occupancy of introduced strain (S24).

    Description / Table of Contents: Riassunto Il metodo di Chisnell-Chester-Whitham è stato usato per studiare la propagazione di onde d’urto divergenti cilindriche e piane attraverso un gas ideale in presenza di un campo magnetico che ha solo componenti costanti assiali e azimutali, contemporaneamente per casi deboli e forti. Assumendo una distribuzione di densità iniziale ϱ0 = ϱ′r −W , dove ϱ′ è la densità al piano/asse di simmetria ew è una costante, si sono ottenute le espressioni analitiche per la velocità d’urto e la forza d’urto. Le espressioni per la pressione, la densità e la velocità delle particelle immediatamente dopo l’urto sono state determinate per entrambi i casi.
    Notes: Summary The Chisnell-Chester-Whitham method has been used to study the propagation of diverging plane and cylindrical shock waves through an ideal gas in the presence of a magnetic field having only constant axial and azimuthal components, simultaneously for both weak and strong cases. By assuming an initial density distribution ϱ0 = ϱ′r −W , where ϱ′ is the density at the plane/axis of symmetry andw is a constant, the analytical expressions for shock velocity and shock strength have been obtained. The expressions for the pressure, the density and the particle velocity immediately behind the shock have been derived for both the cases.
