Newfoundland livestock farmers import all feed grain legumes. Our objective was to compare field pea (Pisum sativum L.) and soybean [Glycine max (L.) Merr.] nodule formation, plant growth, grain and protein yield potential in Newfoundland. Two-year experimental mean pea yield was high (≈0.3 t grain ha–1), although lodging was severe. Vision soybean yielded around 400 kg grain protein ha–1 when seeds were inoculated, even with soil temperatures below 20°C. Despite reasonable yield potentials, agronomic adaptation problems mitigate against the local production of all common feed grain legumes in the near future. Key words: Pisum sativum; Glycine max; lupins; faba beans; inoculant

Six new species of other stem flies infesting mostly legumes were also discovered under the genus Melanagromyza (stem flies) from Pantnagar, Northern India. These were: M. species new ex stems of Cassia sp. (proposed name M. pathaki new species); M. species new ex stems of Glycine max (Linn.) Merril. (proposed name M. glycini new species); M. species new ex stems of Medicago denticulata willd. (proposed name M. denticulata Willd. new species); M. species new ex stems of Pisum sativum Linn. (proposed name M. pisiphaga new species); M. species new ex stems of Trifolium pratense Linn,. (proposed name M. sehgali new species) and M. species new ex stems of Vicia faba Linn. (proposed name M. vicivora new species). New names have been proposed to them as per International rules of Zoological Nomenclature. Other stem flies redescribed by author include: Ophiomyia centrosematis de Meijere, Opmiormyia phaseoli (Tryon) and Ophiomyia cicerivora. More than one thousand male genitalia slides were prepared for this study. Variations in morphology and genitalia characters have been described between and within the species. Melanagromyza sojae (Zehtner) has been redescribed here. DOI: http://dx.doi.org/10.3126/njbs.v2i0.7491 Nepalese Journal of Biosciences 2 : 64-70 (2012)

The site of uptake of nitrofen (2,4-dichlorophenyl-p-nitrophenyl ether) and oxyfluorfen [2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene] was studied using a double pot technique. Sorghum [Sorghum bicolor(L.) Moench ‘RS610′] and pea (Pisum sativumL. ‘Alaska’) were the test plants. Herbicidal activity measured by the reduction in fresh weight of the roots and shoots of treated plants showed that exposure of the shoot zone to the herbicides caused much more injury to the plants than root exposure. Translocation of both compounds from root applications to tops of pea and sorghum was studied using14C-labeled herbicides. There was very little movement of the compounds from the roots of both species. Translocation of the compounds from foliage application was studied using greenbean (Phaseolus vulgarisL. ‘Spartan Arrow’) and soybean [Glycine max(L.) Merr ‘Wayne’]. Almost all of the applied14C-herbicides remained at the point of application.

Nodules of certain N2-fixing root nodules are substantially enriched in 15N compared with non-nodular tissues. This enrichment usually resides largely within bacteroids. Isotope discrimination associated with export of ammonia(um) from the bacteroid would result in 15N enrichment of NH4+ within bac- teroids. Bacteroid protein synthesis from this pool of 15N enriched NH4+ would then account for enrichment of the bacteroids. Measurements of 15N abundances of total N and free NH4+ in nodule fractions from lupins (Lupinus luteus), soybeans (Glycine max) and peas (Pisum sativum) showed this was not the case. With the inocula used in experiments reported here, lupin and soybean nodules were enriched in 15N, while pea nodules were not. There was no correlation between 15N abundances of NH4+ and total N in the nodule fractions (r= 0.445, P> 0.2). We conclude that isotope discrimination associated with ammonia(um) transport does not explain the 15N elevation of lupin and soybean nodules. We also conclude, on the basis of the large isotope effect for the equilibrium between NH4+ and NH3, that most of the ammonia(um) is exported from bacteroids as NH4+ rather than NH3. We also measured the 15N abundance of free amide N. There was a strong correlation between 15N abundances of free amide N and total N in nodule fractions (r=0.924, P<0,001), suggesting that amide N is a significant source of N to the amino acid pools from which proteins are synthesised.
