an experiment was conducted at ecbatan research station in hamedan in two years (1998-99) to study the effects of planting density and methods and also seed clove size on yield of hamedan garlic. the experiment was in factorial 3 x 3x 3 in randomized complete block design with three cultivation methods, three sizes of seeds and three plant densities in three replications. the data were analized...

fenugreek (trigonella foenum-graecum l.), wild or cultivated, is widely distributed throughout the world and belongs to the fabacecae family. it is an old medicinal plant and has been commonly used as a traditional food and medicine. fenugreek is known to have hypoglycemic, and hypocholesterolaemic, effects. recent research has identified fenugreek as a valuable medicinal plant with potential f...

The properties and capacities of the ligninolytic enzymes of Daedaleopsis spp. are still unknown. This is the first study on the effect of plant residues and period of cultivation on the properties of Mn-oxidizing peroxidases and laccases of D. confragosa and D. tricolor, as well as their ligninolytic potentials. Wheat straw was the optimal carbon source for synthesis of highly active Mn-depend...

Jatropha is an important second-generation biofuel plant. Salinity is a major factor adversely impacting the growth and yield of several plants including Jatropha. SbNHX1 is a vacuolar Na⁺/H⁺ antiporter gene that compartmentalises excess Na⁺ ions into the vacuole and maintains ion homeostasis. We have previously cloned and characterised the SbNHX1 gene from an extreme halophyte, Salicornia brac...

Recently, the so-called "plant factory with artificial lighting" (PFAL) approach has been developed to provide safe and steady food production. Although PFALs can produce high-yielding and high-quality plants, the high plant density in these systems accelerates leaf senescence in the bottom (or outer) leaves owing to shading by the upper (or inner) leaves and by neighboring plants. This decreas...

This study aimed to assess microbial community diversity in recycled nutrient solutions used in soil-less glasshouse cultivation of tomato. One hundred bacterial strains, twenty oomycetes and 6 fungi were isolated and identified through genomic DNA isolation, PCR amplification of the ribosomal DNA region and database interrogations. Similarities of ITS regions with known species ranged from 95%...

In order to finding cultivars with high yield and compatible with potato in the form of fall cultivation in jiroft area, an experiment in randomized complete block design with three replication, was done in Jiroft agricultural research center in 2013. In this experiment height plant, No. Stem, Tuber diameter, Tuber weight/plant, No. tuber and yield were examined. Effect Prevent Freezing Cropaid...

Lack of awareness of the critical factors involved in production of plants and sometimes, the cultivation of plants in areas unsusceptible to plant, can increase the amount of chemical fertilizer consumption in order to compensate the subsequent reduction of plant yield. This would increase environmental pollution. Thus, identifying of suitable areas where could supply plants initial needs of t...
