This study was conducted to determine the effects of anticipated future level of CO2 on growth and dry matter partitioning of mungbean (Vigna radiata). Plants were grown from seedlings to maturity inside the open top chamber under amhient CO2 (350 +/- 25 microL L(-1)) and elevated CO2 (600 +/- 50 microL L(-1)) at Indian Agricultural Research Institute, New Delhi (India). Plants were harvested a...

Nodulated cowpea (Vigna unguiculata L. Walp. cv Vita 3:Bradyrhizobium CB 756) plants were cultured with their whole root system or crown root nodulation zone maintained for periods from 5 to 69 days after planting in atmospheres containing a range of pO(2) (1-80%, v/v) while the rest of the plant grew in normal air. Growth (dry matter yield) and N(2) fixation were largely unaffected by pO(2) fr...

BACKGROUND The objective of this study was to dissect into quantitative trait loci (QTLs) the large morphological and physiological differences between cultivated azuki bean (Vigna angularis) and a wild relative and to infer the commonalities of the QTLs for domestication-related traits across the Asian Vigna and with other warm-season legumes. METHODS Two linkage maps, for the BC(1)F(1) and ...

Hexane, acetone, and methanol extracts from Gnidia kaussiana Meisn (Thymeleaceae), each at two dosages (0.2 and 1 ml/50 g grains corresponding, respectively to 1 and 5g/kg), and neem seed oil (NSO), used as standard insecticide were evaluated for repellence, toxicity to Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) adults, F1 progeny inhibition, persistence and as grain protectant d...

A field experiment was conducted at the Pulse Research Centre of Bangladesh Agricultural Research Institute, Ishurdi, Pabna during Kharif-II season of 2010 to evaluate the efficacy of five herbicides for controlling weeds associated with mungbean (BARI Mung-6). The five herbicides such were: Paraxon (27.6% WV Paraquat dichloride salt), M-clor 5G (Butaclor), Topstar 40 WP (40% Oxadiargyl), Hamme...

Several technologies are being applied for treatment of palm oil mill wastes. Among them, the biological treatments (vermicomposting) have widely been recognized as one of the most efficient and eco-friendly methods for converting organic waste materials into valuable products. The present study focuses on vermicomposting of acidic palm oil mill effluent (POME) mixed with the palm pressed fibre...

Rhizobium strains nodulating green gram [Vigna radiata (L.) Wilczek] were found to produce bacteriocin on modified Bergersen's medium and inhibited the growth of homologous Rhizobium strains. Four bacteriocin producing and four bacteriocin non-producing strains were compared for their effect on nodulation, in planta nitrogenase activity and plant dry weight of green gram. The bacteriocin produc...

Compounds released by mungbean roots potentially represent an enormous source of nitrogen (N) and carbon (C) in mungbean-oat intercropping systems. In this study, an in situ experiment was conducted using a 15N - 13C double stem-feeding method to measure N and C derived from the rhizodeposition (NdfR and CdfR) of mungbean and their transfer to oats in an intercropping system. Mungbean plants we...

Members of the genus Burkholderia (β-proteobacteria) have only recently been shown to be able to establish a nitrogen-fixing symbiosis with several legumes, which is why they are also referred to as β-rhizobia. Therefore, very little is known about the competitiveness of these species to nodulate different legume host plants. In this study, we tested the competitiveness of several Burkholderia ...

Early planting of bambara groundnuts (Vigna subterranea L. Verdc) in the southern Africa enables farmers to fetch premium prices before the markets are flooded with produce from the main summer growing period. However, adaptation of the crop outside the main growing season has not been studied in Zimbabwe. Therefore, this study evaluated 20 varieties at four planting dates covering contrasting ...
