Re-orienting participatory plant breeding for wider impact
This paper concerns the need to re-conceptualise participatory crop improvement in order to explore new ways of making the outcomes of scientific plant breeding and knowledge production more effective, accessible and relevant to those smallholders who hitherto have been unable to benefit more fully from the advances in formal crop improvement. Main perspectives on participatory crop research are reviewed and...

Physiological and ecological investigation on adoption of some groundcover plants as turfgrass alternatives in arid landscape region of Kish Island during cool season
Kish Island located in the south of Iran with 90 square kilometers, having limited expansion, sustainable ecology, erotology characteristics including low soil depth and low sweet water, does not allow the variability in plant coverage in the Island’s landscape. Investigation should be conducted on groundcover species having some abilities in adapting to such environment,...

Malathion toxicity in Nile tilapia, Oreochromis niloticus - A haemotological and biochemical study
Deliberate or accidental contamination of ponds by widely utilized organophophorous (OP) insecticides, such as malathion is a potential problem for aquaculture in tropical countries. The aim of the study was to investigate the toxic effects of malathion (0, 0.5, 1.0, 1.50 and 2 mg L−1) toxicity in the Nile tilapia (Oreochromis niloticus; 15.0 cm length and 50.0 g weight) by correlation...

Effect of converter sludge, and its mixtures with organic matter, elemental sulfur and sulfuric acid on availability of iron, phosphorus and manganese of 3 calcareous soils from central Iran
Application of industrial wastes as soil amendment and fertilizers is now a common practice in agriculture. The effect of application of converter sludge, along with organic matter (alfalfa powder), elemental sulfur and sulfuric acid to 3 calcareous soils from central Iran was investigated in an incubation study. Converter sludge used contained 64% iron oxides. Treatments included 0, 2 and 4% pure converter...

Potential decline in soil quality attributes as a result of land use change in a hillslope in Lordegan, Western Iran
The aim of the study was to investigate the potential decline in soil quality attributes as a result of land use change in Lordegan area in the Chaharmahal Va Bakhtiari Province, Western Iran. Two of the most important factors associated with soil quality concept are: (1) soil has both inherent and dynamic properties and (2) soil quality assessment must reflect biological, chemical and physical properties....

Genetic diversity among crown and root rot isolates of Rhizoctonia solani isolated from cucurbits using PCR-based techniques
Twenty three (n=23) isolates of Rhizoctonia solani were obtained from root, crown and rhizosphere of cucumber, pumpkin, watermelon and melon plants. Investigation of the anastomosis groups (AGs) showed that all of the isolates belonged to AG4. Twenty three of R. solani AG4 were measured for disease severity according to their geographical origins and host plants. The pathogenicity test revealed that the...

Bioaccumulation of Cr, Hg, As, Pb, Cu and Ni with the ability for hyperaccumulation by Amaranthus dubius
Amaranthus dubius is a nutritious leafy vegetable that is widely distributed in Africa, Asia and South America. The rapid growth and biomass makes them one of the highest yielding leafy crops, which may be valuable for phytoremediation. Thus, this study investigates the potential of A. dubius for the hyperaccumulation and distribution of chromium (Cr), mercury (Hg), arsenic (As), lead (Pb), copper (Cu) and...

Characterization and expression of β -1, 3 glucanase gene cloned from Malus hupehensis
MhGlu, a β-1, 3-glucanase cDNA, was cloned from Malus hupehensis (Pamp.) Rehd by in silico cloning and validated with RT-PCR. MhGlu has an intron and possess 84, 83, and 77% nucleotide identity and 84, 74, and 76% amino acid identity with Prunus persica, Prunus avium, and Vitis riparia, respectively. MhGlu genomic DNA sequence and promoter sequence including the salicylic acid (SA) motif, methyl...

Sericulture extension structural equation modeling to revitalizing silkworm cocoon production in Iranian sericulturists’ view
Sericulture as an agrarian small-scale industry suits both marginal and small land holders because of its high returns, and it creates opportunity for family employment. Iran has long history in cocoon and silk production, but the demand for rearing silkworm during recent years has had a significant reduction. This study examines sericulture extension as a strategy for revitalizing silkworm cocoon production from...

Changes of groundwater conditions on Jeju volcanic island, Korea: implications for sustainable agriculture
Groundwater is the sole source of fresh water in the volcanic Jeju Island due to the absence of any perennial streams. Groundwater exploitation has been extensive and intensive for agricultural, domestic consumption, including drinking, and industrial purposes. In addition, ground source heat pumps (GSHPs; open, closed and underground air types) are now gaining popularity. The conservation of groundwater...
