The Himalayan endemic alpine genus Roscoea, like other members of ginger family, exhibits the combination of floral traits that would fit pollination by long distant foragers such as bees, birds or flies. We studied the pollination biology of Roscoea alpina, observed potential floral visitors and determined their foraging behaviour, visitation frequency and pollination efficiency, to seek evide...

Bark beetles, fuels and future fire hazard in contrasting conifer forests of Greater Yellowstone" (2013). ABSTRACT The extent and severity of bark beetle (Curculionidae: Scolytinae) epidemics and the frequency of large, severe fires have reached unprecedented levels in recent decades, and these trends are expected to continue with ongoing climate change. Insects and fire have tremendous ecologi...

Cowpea bruchid is a major constraint to cowpea production. Easy identification of resistant/tolerant accessions infestation has been challenge in resistant breeding programmes. Hence, the study was aimed evaluate variations some morphological characters between and susceptible accessions, correlating them with their tolerance status hope identifying pointer character(s) that can facilitate easy...

Background: Cowpea [Vigna unguiculata (L.) Walp] is most widely grown pulse-cum-vegetable crop. It plays an important role in maintaining soil fertility. Besides, nitrogen which fixed the from atmosphere by crop specific Rhizobium found root nodules of this crop, phosphorus another element inter-alia enhances fixation capability In addition to biologically nitrogen, also requires through fertil...

Choosing the species suitable for cultivation in intercropped systems is a critical limiting factor grain and forage production. This study aimed to evaluate growth, nodulation, production, physiology of cowpea (Vigna unguiculata) guandu bean (Cajanus cajan) with buffel grass (Cenchrus ciliaris) Eucalyptus urograndis (Eucalyptus grandis × urophylla) an integrated production system. Two experime...

Abstract Background and aims Calcium deficiency is evident in populations worldwide combating this could be addressed with the biofortification of staple crops. Consequently, identification Ca concentration breeding trials would essential. Here we report use energy dispersive x-ray fluorescence (EDXRF) for rapid screening seed samples. Methods Grain samples rice, wheat, pearl millet, bean, maiz...

Rhizobia classified as Bradyrhizobium spp. comprise a highly heterogeneous group of bacteria that exhibit differential symbiotic characteristics on hosts in the cowpea miscellany cross-inoculation group. To delineate the degree of specificity exhibited by four legumes in the cowpea miscellany, we tested the symbiotic characteristics of indigenous cowpea bradyrhizobia on cowpea (Vigna unguiculat...
