Use of biochemical indices and antioxidant enzymes as a screening technique for drought tolerance in Chickpea genotypes (Cicer arietinum L.)
In order to evaluate the physiological and biochemical traits regarding drought tolerance and further to determine the best criteria for screening and identification of drought tolerant chickpea genotypes, an experiment was conducted in controlled conditions in the Plant Science Research Center of Ferdowsi University of Mashhad in Iran. In this study, two tolerant genotypes (MCC392 and MCC877) and two...

Impact of different litters on growth and production of a megascolecid earthworm (Perionyx sansibaricus) in experimental condition
The paper dealt with the impact of different litters on biomass, instantaneous growth and secondary production of Perionyx sansibaricus cultured in artificial soil for 21 weeks. Biomass of the P. sansibaricus in Mangifera indica litter varied from a minimum value of 30.25 to maximum value of 380.51 g dry wt/m2, 20.34 to 340.89 g dry wt/m2 in Acacia...

Growth and yield of sweet potato (Ipomoea batatas L.) as influenced by integrated application of chicken manure and inorganic fertilizer
Field experiments were conducted at Wa (Guinea savanna agro-ecological zone) and Mampong-Ashanti (forest-savanna transition agro-ecological zone) in 2007 and 2008 to determine the growth and yield response of sweet potato (Ipomoea batatas L.) to chicken manure, inorganic fertilizer (NPK, 15-15-15) and combinations thereof. The experimental design used was a randomized complete block design (RCBD) with...

The distribution of Russian Wheat Aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae) in Turkey
The Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), is one of the most economically important and widely distributed pests of wheat in the world. In 1962, D. noxia caused crop losses between 25 and 60% in the central province of Konya, Turkey. In this study, the current status of the pest in wheat-producing areas of Turkey was investigated along a route from Izmir...

Assessment of rural households ‘cooking energy choice during kerosene subsidy in Nigeria: A case study of Oluyole Local Government Area of Oyo State
The choice of domestic cooking energy in rural Nigeria is an issue for addressing deforestation and health hazards resulting from indoor air pollution. The study compared the demand for different cooking energy sources before and after implementation of kerosene subsidy and determined the correlates of choosing fuel wood/charcoal. The data were collected with structured questionnaires administered to 120...

Nodulation, leaf harvesting intensity and interval of the black-eyed bean (BEB) (Vigna unguiculata L. Walpers) cowpea type at the University of Zimbabwe, Harare, Zimbabwe
A glasshouse pot experiment was carried out at the University of Zimbabwe, Crop Science Department in 2006 to 2007 rainy season to determine the effect of leaf harvesting intensity and interval on cowpea biological nitrogen fixation through nodulation. The experiment was designed as a three factor factorial. The first factor was leaf harvesting frequency with two levels: leaves harvested weekly or...

Growth and Cu and Zn uptake of two forage grasses affected by application of vermicompost spiked with different metal contents
To identify environmental risks of vermicompost-borne pollutants after consecutive application for different times, pot experiments were conducted to evaluate the effects of application of polluted vermicompost produced by Eisenia fetida on growth and Cu and Zn uptake of Mexico corn (Euchlaena mexicana) and Sudan grass (Sorghum hybrid Sudangrass) as well as soil characteristics. The...

Assessment of spatial variability of selected soil chemical properties in a communal irrigation scheme under resource-poor farming conditions in Vhembe District of Limpopo Province, South Africa
An understanding of spatial variability of chemical soil properties is necessary for proper nutrient management. Therefore spatial variabilities of soil pH, P, K, Ca and Mg in communal irrigation scheme under resource-poor farming conditions were determined. A total of 230 soil samples were collected from two soil depths (0 to 30 and 30 to 60 cm) at 100 m grid intervals. Basic statistics and geostatistical...
