Phytoremediation: Curing soil problems with crops
Among the different contaminants in the environment, heavy metals (HMs) are unique due to the fact that they cannot be broken down to non-toxic forms. According to the reports published worldwide, these metals are released into the environment by both natural and anthropogenic sources, especially, mining and industrial activities, and automobile exhausts (for lead). They leach into underground waters, moving...

Social capital between farmers of Iran
Social capital can potentially be used for wrong reasons such as criminal activities, self interests and the creation of unequal communities. In this regard, the issue of developing communities raises concern because social capital has not sufficiently been researched and documented in rural areas of the developing world. The purpose of this study was the assessment of social capital between rural farmers in...

The leaf growth model and influencing factors in Phalaenopsis orchid
To evaluate the factors affecting the growth characteristics of Phalaenopsis leaves, the leaf-length growth patterns of two Phalaenopsis varieties, the red-flower Phalaenopsis clones ‘LB9506’ and ‘LB9508’, were measured under different environment condition such as day temperature, light intensity, and fertilizer rates. The fitting-agreement of three...

Storage pests of maize and their status in Jimma Zone, Ethiopia
An experiment was conducted in 2004 to assess the major pests associated with stored maize, the damage and losses they cause in Jimma Zone, Oromia Regional State. Fifty farm stores were assessed. Seventeen arthropods, thirteen Coleopterans, three Lepidopterans and one Acarina were documented from the samples collected. Maize weevil (Sitophilus zeamais) followed by grain moth (Sitotroga...

Lengthâ€weight relationship and condition of five marine fish species collected by shrimp trawls in Bushehr coastal waters, Northern Persian Gulf
The length-weight relationships (LWR) and relative condition factor were calculated for five marine fish species collected by shrimp trawls from Iranian waters of the Persian Gulf. Sampling was carried out with bottom trawl net (with 40 and 50 mm mesh size (stretched length) in the cod-end and panel) during June to August 2011. Trawling took place at depths ranging from 7 to 30 m. The values of the...

Management of post-harvest Pectobacterium soft rot of cabbage (Brassica oleracea var capitata L.) by biocides and packing material
Bioassay studies of several biocides against Pectobacterium carotovorum ssp. carotovorum revealed that ciprofloxacin proved highly inhibitive to bacterial growth by producing highest inhibition zone (21 mm) at a concentration of 200 µg ml-1 followed by penicillin, tetracycline, and oxytetracycline. Other test chemicals viz., amoxicillin, striplin, azithromycine, mercuric...

Predicting soil and forest floor carbon stocks in Western Anatolian Scots pine stands, Turkey
The objective of this study was to determine the models which estimate the soil plus forest floor carbon stocks (TC) using some stand, climate, and topographic parameters in Scots pine (Pinus sylvestris L.) stands. 40 sample plots were taken from sites differing in aspects, elevation, slope degree, slope position, and stand growth condition. TC of the stands, as dependent variables, and stand,...

Effect of ultraviolet-C (UV-C) illumination on postharvest quality and bioactive compounds in yellow bell pepper fruit (Capsicum annuum L.) during storage
The effects of ultraviolet-C (UV-C) illumination on postharvest quality and bioactive compounds of yellow bell pepper during refrigerated storage were investigated. The yellow bell pepper fruit were illuminated with three different UV-C dosages, 2.2, 4.4 and 6.6 kJ m-2 and then stored at 12 ± 1°C for 15 days. UV-C illumination at 6.6 kJ m-2 showed the best results in maintaining...

Yield and yield components in vegetable cowpea on an ultisol
Field trials were conducted from 2001 to 2004 at the research farm of the Michael Okpara University of Agriculture, Umudike, South Eastern Nigeria to evaluate the yield and its components in nine vegetable cowpea cultivars. The cultivars differed significantly in yield and most of the components and the yield were not stable across the years of the study though, few cultivars seem to have stable yields. Pod...

Evaluation of some morphological traits associated with wheat yield under terminal drought stress
This study was carried out at the Seed and Plant Improvement Institute, Karaj (Iran) in 2007/2008 and 2008/2009 growing seasons to investigate the effects of two irrigation regimes (normal irrigation and no irrigation in post-anthesis growth stage) on grain yield of eight wheat cultivars (DM-81-6, DM-82-1, Bahar, DN-11, DN-7, Pishtaz, WS-82-9, and C-85-6). According to the results of variance analysis, it is...

Seed drilling distance applications in sugar beet cultivation
This research was conducted with the Leila sugar beet variety between 2007 and 2009 at the Sugar Institute Etimesgut and Ilgın experimental stations, and the aim of this research was to determine the most suitable seed distance in rows for sugar beet cultivation. Both experimental stations were located in the Central Anatolia region. Six different sowing distances were specified as the following methods: 8...
