In addition to farm operations, power tillers in Iran are also engaged in load and passenger transportation. Inspite of their noise and adverse effects on power tiller drivers and bystanders, they have not been adequatly investigated. The initial survey in the present investigation on a 13-hp power tiller at 2200 rpm engine speed revealed that its noise was 92 dB(A), compared to the standard l...

Establishment of perennial grass seedlings is critical for repairing rangeland ecosystems in the Western United States. Mineral N in the soil may be one of the controlling factors for seedling establishment and may improve the competitive ability of perennial grasses compared to the annual grass, cheatgrass (Bromus tectorum L.). A greenhouse experiment was conducted to investigate the effects o...

BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...

A new mixed-model method was developed for mapping quantitative trait loci (QTL) by incorporating multiple polygenic covariance structures. First, we used genome-wide markers to calculate six different kinship matrices. We then partitioned the total genetic variance into six variance components, one corresponding to each kinship matrix, including the additive, dominance, additive × additive, do...

Although the introduction of semi-dwarf trait into rice has led to improved lodging resistance making it capable of supporting high grain yield, lodging still remains a concern when attempting to further increase the grain yield of rice. However, improving the lodging resistance in rice by depending on the semi-dwarf trait alone is possible only up to a certain limit, beyond which other traits ...

the aim of this study was evaluation of some of characters, estimation of their heritability and their relationship in 104 recombinant inbred lines population of durum wheat under pot and field conditions. the inbred lines, their parents and control genotypes were evaluated in completely randomized design in 3 replications at pot study and in augment design at field condition. analysis of varia...

More efficient resource use, especially nitrogen (N) in agricultural fields could considerably reduce the losses and spillover effects on environment. Cereal-legume mixtures can lead to more uptake of growth-limiting resources, increase stabilize yields, due variation functional traits that facilitate partitioning niche space. Here we identify crop with optimal N use two selected cereal-legume ...

This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...

Genetic variability, correlation and path coefficients for fifteen agro-morphological traits were studied on 100 oat lines including two checks. Genotypic phenotypic of variation high leaf number per tiller weight panicle. Traits such as plant, tiller, panicle, stem width, individual plant yield, length internode thousand seed showed heritability accompanied by genetic advance indicating that t...
