in order to investigate the effect of chemical herbicides on control of broad leaf weeds of common bean, an experiment was conducted in 2007 at yasouj with 12 treatments in a randomized complete block design with 3 replications. treatments consisted of preplant application of trifluralin herbicide at 960 g ai ha-1; postemergence application of bentazon at 1200 g ai ha-1; imaztapir at 50, 75 and...

The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...

The Universidad Complutense de Madrid (UCM) survey is a long-term project aimed at finding and analyzing star-forming galaxies detected by their Ha emission in Schmidt objective-prism plates. The instrumental setup limits the volume of the universe surveyed to a redshift z = 0.045. So far we have discovered several hundred emission-line galaxies (ELGs) undergoing star formation at a wide range ...

Densification and handling of crop residue, especially paddy straw is a critical issue due to very high moisture content as well relative humidity abundant amount. In the present study, different densification processes using field balers stationary were evaluated in chopped full-length straw. it was found that minimum energy required for T1 (50.16 MJ∙t−1) followed by T2 (102.65 MJ∙t−1), T3 (11...

Soil is a non-renewable resource essential for life existence. During the last decades it has been threatened by accelerating erosion with negative consequences environment and economy. The aim of current study was to assess soil loss changes in typical Mediterranean ecosystem Northern Greece, under climate change. To this end, freely available geospatial data collected processed using open-sou...

in order to evaluate the effects of seed priming and different levels of nitrogen on yield and yield components of two corn (zea mays) hybrids, an experiment was carried out as split plot factorial based on a randomized complete block design (rcbd) with four replications in agricultural research station of shahrood university of technology. the treatments were urea levels (150, 250, 350 kg/ha) ...
