Saffron as a valuable spice: A comprehensive review

  Saffron (Crocus sativus L.) is an autumn flowering high value, low volume spice crop that grows throughout Mediterranean Europe and Western Asia between 10° west and 80° east longitudes and 30 to 50° north latitudes. At present, saffron production is limited to Iran and countries of older civilizations such as India, Spain, Italy, Greece, and Turkey. Its cultivation is under threat of...

A novel strategy for the identification of 73 Prunus domestica cultivars using random amplified polymorphic DNA (RAPD) markers

  Despite the usefulness of DNA marker techniques, various DNA markers have not been widely applied for practical cultivar identification. We developed a novel strategy based on DNA molecular fingerprints from the genotyped plant individuals, following which a cultivar identification diagram (CID) was manually generated and used as referable information for quick plant and/or seed sample identification. Based...

Modelling greenhouse air temperature using evolutionary algorithms in auto regressive models

  This paper presents comparison of genetic algorithms (GAs) and evolutionary programming (EP) to estimate parameters of a linear auto regressive model with external input (ARX) and an auto regressive moving average model with external input structures (ARMAX) that predict the behavior of air temperature within a greenhouse. Data groups were used to estimate and validate models and these data groups were 20:80,...

Influence of diverse pollen source on compatibility reaction and subsequent effect on quality attributes of sweet cherry

  Sweet cherry is self incompatible due to having a gametophytic self – incompatibility system. S alleles in the style and pollen determine possible crossing relationship and ultimate fruit set. Complete knowledge of the s allele constitution of cultivars is import out for sweet cherry growers and breeders. Natural pollination in cultivar Van resulted in high fruit set as compared to controlled crossing...

Comparative study of the concentration of mercury and lead and the chemical characteristics of Japanese and Korean chub mackerel (Scomber japonicas Houttuyn, 1782) in the East China Sea

  We compared heavy metals and proximate composition of Japanese and Korean chub mackerel from the East China Sea. J-mackerel showed higher mercury content than K-mackerel, but no difference in lead content was observed. J-mackerel had significantly lower ash content than K-mackerel. There were no significant differences in saturated, monounsaturated, and polyunsaturated fatty acids, but J-mackerel showed...

Comparison of chemical fertilizer, fish offal’s fertilizer and manure applied to tomato and onion

  Fertilizer is a critical input for improving production and increasing crop yields. The effect of chemical fertilizer, fish offal’s fertilizer and manure on marketable yield and other parameter of tomato (Lycopersicon esculentum) and Adama red onion (Allium cepa) were compared. The experiment was laid as a randomized complete block design (RCBD), with three treatments; chemical fertilizer (T1), fish...

Peroxidase and polyphenol oxidase activity on the yield of grafted and ungrafted cucumber plants

  The first experiment was carried out under green house and involved nine treatments: ‘Tsuyoi’ cucumber, ‘Shelper’ squash and ‘Green-stripped cushaw squash’ ungrafted plants and ‘Tsuyoi’ cucumber plants grafted onto ‘Shelper’ squash and ‘Green-stripped cushaw squash (lower, mid and upper region of the recommended and non-recommended rootstock,...

Qualitative land suitability evaluation for Tobacco (Nicotiana tabacum) in Talesh, Iran

  Land suitability assessment was conducted for flue-cure Tobacco (Nicotiana tabacum) in an area including 2880 ha in Talesh site in Guilan province, north of Iran. Using the findings of the semi-detailed soil studies for this area, 18 land units were selected. Then morphological and physico-chemical properties were determined. The results showed that soils were in three orders (Inceptisols, Entisols and...

Cellulolytic bacterial biodiversity in long-term manure experimental sites

  To study the Influence of long-term application of manure on cellulolytic bacterial diversity, 54 efficient cellulolytic bacterial cultures were isolated from two long-term manure experimental field sites of Berlin-Dahlem (established in 1923) and BadLauchstädt (established in 1902). The sequence divergence of highly conserved region of 16S rDNA was exploited by restriction analysis of PCR-amplified 16S...

A new process to promote the use of controlled mycorrhization practice in forest nurseries

  The aims of this study were to test a new mycorrhizal inoculation process using a “catalyser” of the mycorrhizal establishment (termite mounds of Macrotermes subhyalinus) to minimize the requested volume of fungal inoculum added to the cultural substrate. The effects of the termite mound were explored on mycorrhiza formation between an Australian Acacia, Acacia holosericea and...

Teat perimeters for South African Boer and Nguni goats: Use of these measurements to predict milk production potential and kids’ growth

  The aim of this trial was to assess the possibility of using teat perimeter in estimating milk production potential and kids’ growth rate in Nguni and Boer goats of South Africa. Traditionally, the productive capacity of goats doe, are judged to a large extent by the physical phenotypic characteristics. In this trial a 2 × 2 factorial  design (two goat breeds and two nutritional management...

Effect of dune sand mulch on water recharging into root zone using drip lines

  Surface drip irrigation has been used for agricultural production for more than three decades. Surface drip irrigation (SDI) can maintain sufficient water content in soil for seed germination and emergence, seedling development and plant growth. Insufficient water content in the root zone may cause crop failure. In this study, the effects of Tottori dune sand mulch on drip lines on water recharging into root...

Dry matter accumulation studies at different stages of crop growth in mesta (Hibiscus cannabinus)

In crop like mesta, stem is the main source of fibre and therefore, fibre yield depends greatly on fresh biomass yield as well as on dry stalk yields of a particular variety at the time of harvesting. At 30 DAS (days after sowing), dry matter accumulation in stem varied significantly with respect to different plant spacing, varieties and nutrient sources. Between the varieties, variety HS-108 had recorded significantly...
