This experiment aimed to evaluate the ruminal degradability in situ of the dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Guinea grass silages. The experimental design was completely randomized with six treatments and six repetitions: Guinea grass silage, Guinea grass silage inoculated with 10% wheat bran, Guinea grass silage inoculated with...

A recently published procedure to enrich for efficient competitive root tip colonizers (I. Kuiper, G. V. Bloemberg, and B. J. J. Lugtenberg, Mol. Plant-Microbe Interact. 14:1197-1205) after bacterization of seeds was applied to isolate efficient competitive root tip colonizers for both the dicotyledenous plant tomato and the monocotyledenous plant grass from a random Tn5luxAB mutant bank of the...

Dwarfism traits in Zea mays are regulated by multiple factors including the hormone auxin. Dwarf brachytic2 (br2) mutants harbour lesions in the gene encoding an orthologue of Arabidopsis thaliana ABCB1 which functions in auxin efflux out of meristematic regions in the shoot and root. br2 mesocotyls and coleoptiles exhibit reduced auxin transport. However, the dwarf stature of br2 derives from ...

This article attempts to present the local governments’ executives with a number of options to consider as they deal with the complex and ever changing questions of financial management for the local community. The paper provides local government officials quick access to a framework of ideas and suggestions that work within the hierarchy of financial management. Finance is immensely important ...

This work aimed to evaluate density of associative diazotrophic bacteria populations in soil and grass root samples from heavy metal contaminated sites, and to characterize isolates from these populations, both, phenotypically (Zinc, Cadmium and NaCl tolerance in vitro, and protein profiles) and genotypically (16S rDNA sequencing), as compared to type strains of known diazotrophic species. Dens...

Napier grass is a perennial, tropical C-4 grass that can produce large amounts of forage. However, low temperatures and drought stress limit its productivity and nutritive value as a forage. To overcome these limitations, pearl millet × napier grass hybrids (PMN) were developed. It was hypothesized that PMN hybrids were more drought-tolerant, produced higher yields, and had higher nutritive val...

Many arid grassland communities are changing from grass dominance to shrub dominance, but the mechanisms involved in this conversion process are not completely understood. Aeolian processes likely contribute to this conversion from grassland to shrubland. The purpose of this research is to provide information regarding how vegetation changes occur in an arid grassland as a result of aeolian sed...

Increasing plant diversity in the perennial phase of pasture-crop rotations is predicted to positively affect belowground productivity and microbial communities and, turn, augment agroecosystem services including soil health carbon storage. Using two grass one legume forage species grown as monocultures combined four intercropped combinations, we evaluated how identity richness influence produc...

in order to investigate the possibility of planting grass pea and common vetch crops after harvesting wheat and to evaluate the effects of  green manure of these crops on yield of potato-wheat in croprotation cycle, this research was carried out using a randomized complete block design with four replications during 2006-2010 at khair-abad research station, zanjan, iran. the treatments were eith...

Water and fertilizers affect the nitrogen (N) and phosphorus (P) acquisition and allocation among organs in dominant species in natural vegetation on the semiarid Loess Plateau. This study aimed to clarify the N and P accumulation and N:P ratio at organ and plant level of a local legume species mixed with a grass species under varying water and fertilizer supplies, and thus to fully understand ...
