The importance of marine cadastre for Turkey

Human’s have used the sea for nourishing, getting raw material, advancing technology and providing transportation throughout history. The society have been destroying the eco balance as a result of the manufacturing technologies they use and demolishing many facilities of the future in the long run in an anxiety to earn their keep in the short run. The marine environment, which is the most convenient environment...

Impacts of Zimbabwe European Union micro-project programme (Zim/Eu MPP) in funding smallholder irrigation projects on food security and income levels: A case study of Mopane irrigation scheme in Zvishavane, Midlands province, Zimbabwe

At least 70% of smallholders live in the semi-arid regions IV and V where rainfall is erratic and soils in these regions are derived from granite and generally shallow, light textured and of low fertility. As a result, farmers cannot produce adequate grain to meet their annual household requirements by dry land farming. The Zimbabwe/EU Micro-projects Programme has funded smallholder irrigation projects since 1982 to...

Using precipitation effectiveness variables in indexing drought in semi-arid regions

This study proposes a new drought index based on several precipitation-based parameters to quantify drought hazard in semi arid region. In addition to the practice of using only rainfall volume for indexing drought, the proposed index verifies the potentials of nine other precipitation effectiveness variables (PEVs) onset of rain, cessation of rain, length of rainy and dry season, wet days and dry days within a wet...

Comparative performance of various wheat (Triticum aestivum L.) cultivars to different tillage practices under tropical conditions

Various tillage practices can overcome the delay sowing of wheat in the rice-wheat cropping system of Pakistan to sustain the grain yield by increasing the nutrients and water use efficiency. A field experiment was conducted to evaluate the effect of different tillage practices (zero tillage and conventional) on growth and yield of four wheat (Triticum aestivum L.) cultivars viz. Inqalab-91, Chenab-2000,...

The effects of cold storage of saffron (Crocus sativus L.) corms on morphology, stigma and corm yield

Tests were conducted to determine the effects of cold-storage of saffron (Crocus sativus L.) corms on the first and last flowering dates, harvest periods, saffron stigma yield, flower and leaf numbers, plant height, and asexual daughter corm reproduction in the field and glasshouse at the pre-planting stage. Corms stored at 8°C for 7 and 28 days were compared with controlled corms at room temperature storage at...

Effects of hydrocarbons on temporal changes in soil and crops

Changes in soil chemical properties, plant density and crops yield (maize, winter wheat, winter barley, soybean and oilseed rape) grown in soil contaminated by different degrees of crude oil and drilling fluids were monitored for three years. Drilling fluids had a stronger impact on chemical properties of the studied soil, while plant density and yield were strongly affected by crude oil. The influence of crude oil...

Detection of genetic diversity in Moroccan durum wheat accessions using agro-morphological traits and microsatellite markers

Characterization of germplasm by agro-morphological, biochemical and DNA-markers provide powerful tools to precise germplasm identification, quantify the genetic diversity and to estimate the phylogenetic relationship among accessions in many crop species. The objective of the present study was to characterize a subset of 23 Moroccan relevant durum wheat (Triticum turgidum L. var. durum) accessions selected...

Optimization and characterization of an extracellular proteases from Aspergillus flavus ”MTCC 277”

The present study was undertaken to describe the optimization and characterization of proteases produced by, Aspergillus flavus MTCC 277. This strain exhibited the highest protease production after 4 days of incubation when grown on casein-containing basal salt medium. The optimum temperature of proteases was recorded at 35°C whereas optimum pH was 5 and 9. During the studies on the activity of enzyme with metal...

Impacts of alcohol type, ratio and stirring time on the biodiesel production from waste canola oil

The use of alternative fuels in order to reduce the environmental impacts of diesel emissions has been extensively investigated. Trends in the regional use of biomass-derived fuels, such as alcohols, biodiesel and agricultural residues as a proposed control initiative against elevated carbon monoxide levels in urban areas have expanded to a global scale. Waste cooking oil is considered as the most suitable material due...

An in vitro technique for studying specific Striga resistance mechanisms in sorghum

Witchweed (Striga sp.) is a noxious parasitic weed of many cereals, that causesconsiderable crop damage in the semi-arid tropics. Although, a number of control measures have been suggested, breeding crops which are resistant to the attack is the most feasible and effective way of control. However, breeding efforts have been hampered by the lack of adequate laboratory techniques that uncover critical host-parasite...

Persistent effect of a preparation of essential oil from Xylopia aethiopica against Callosobruchus maculatus (Coleoptera, Bruchidae)

Cowpeas, Vigna unguiculata (Walp), are commonly attacked by Callosobruchus maculatus (Coleoptera, Bruchidae) during storage. Current methods to prevent losses during storage involve synthetic insecticides. Although they have insecticidal efficiency, these products have adverse effects on consumers and the environment. Plant products such as those of Xylopia aethiopica (Annonaceae) are...
