The organophosphate, chlorpyrifos, oxidative stress and the role of some antioxidants: A review

  The present paper reviews the current state of our knowledge of the role of oxidative stress in the mechanism underlying chlorpyrifos poisoning, and the role of some antioxidants in ameliorating adverse effect of pesticides. In order to understand better the nature of oxidative stress, the principle of free radical generation, the body’s normal defense system including antioxidants are discussed. The...

Agricultural land markets and land leasing in the Republic of Macedonia

  This paper aims to identify the driving force that shaped agricultural land structures, land market and land leasing in the Republic of Macedonia. Institutional developments and land reforms have so far been modest, and have not contributed to significant changes in agricultural ownership, operational structures, or land market and land leasing arrangements. Land ownership and land use are bimodal, consisting...

Hydrothermal characteristics of pearl millet (Pennisetum glaucum) flour during cooking into ‘fura’

  The effects of hydration times (HT) (1, 3.5 and 6 h) and cooking times (CT) (20, 40, and 60 min) on the thermal characteristics of cooked pearl millet flour (CPMF) was investigated. The differential scanning calorimetry thermograms depicted two separate endothermic transitions identified as starch gelatinisation (29 to 30°C) and disruption of the starch-lipid complexes (90 to 120°C). The...

Biological characteristics of grafted eggplant on tomato rootstocks

Grafting eggplant (Solanum melongena L.) on tomato rootstock is an effective method to control Verticillium wilt (caused by Verticillium dahliae), a soil-borne disease. This study investigated the fruit quality and biological characteristics associated with disease resistance of eggplants grafted onto tomato rootstocks ‘Lydl’. The plant height, stem diameter, leaf area and root volume of grafted...

Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil

  Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania (Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia populations that nodulate sesbania and ii) effects of lime (0 and 4 t/ha), P-fertilizer (0 and 60 kg/ha) and acid tolerant rhizobia (0and inoculation) on soil...

Dissolved organic carbon and its controls of urban soil in Hefei, Eastern China

  Soil dissolved organic carbon (DOC) plays an important role in the biogeochemical cycling and energy transformation in the ecosystem. The objectives of the study were to assess the impacts of land use types and planation modes on carbon dynamics and to determine the major soil factors influencing the DOC concentration in urban soils. The spatial pattern of DOC was studied with soil sample collection from a...

Carbon sequestration potential of Scenedesmus species (Microalgae) under the fresh water ecosystem

  The study was conducted to investigate the carbon sequestration potential of Scenedesmus species (a microalgae species) under the fresh water ecosystem. Biofixation of CO2 by microalgae mass cultures represents an advanced, climate friendly biological process that enables the direct utilization of fossil CO2streams produced from concentrated sources, such as power plants. The study was...

Behavioural patterns of cattle in the communal areas of the Eastern Cape Province, South Africa

Incorporating knowledge of cattle activity or social behavior in rangeland management has the potential to improve both range condition and cattle productivity through intervention in and using the ongoing expression of behavior to detect veld condition changes. Currently, there is limited information on free ranging cattle activity patterns despite a concerted effort to introduce rotational grazing in communal...

Changes in rainfall characteristics in Southwestern Iran

  The study of rainfall characteristics changes is critical for agricultural, environmental and water resources projects. Generally, trend test performs for evaluation of direction and magnitude of changes, but the test is not able to demonstrate abrupt change in time series if it occurs. In this research work, recent changes of rainfall characteristics of the Karun and Dez watershed, located in southwest of...

Alkali stress induced the accumulation and secretion of organic acids in wheat

In this study, the seedlings of wheat were treated with salt stress (molar ratio of NaCl:Na2SO4 = 1:1) and alkali stress (NaHCO3:Na2CO3 = 1:1). The contents of organic acids and inorganic ions in the seedlings then were measured, and the organic acids in root secretions also were analyzed to probe the roles of organic acids in wheat alkali tolerance. The results showed that the content of Na+ increased...

The importance of a single floral visit of Eucara macrognatha and Tetralonia fraterna (Hymenoptera: Apidae) in the pollination and the yields of Abelmoschus esculentus in Maroua, Cameroon

  Experiments were made to determine the effects of a bee visit on the pollination and the productivity of okra,Abelmoschus esculentus (L.) Moench (Malvaceae). Three treatments were used on 30 randomly-selected plants each. These included Autonomous Self-Pollination (ASP) with flowers from which insects visit, with airborne pollen flow excluded, flowers that received a single bee visit (SBV) of Eucara...
