Zhou, X. B. and Y. h. Chen, 2011. Yield response of winter wheat to row spacing under irrigated and rainfed conditions. Bulg. J. Agric. Sci., 17: 158-166 In China, wheat (Triticum aestivum L.) is cultivated across a wide range of climatic conditions. The average rainfall was recorded at 696.6 mm per year from 1971 to 2008 at Taian in northern China. Considerable variability in the row spacing (...

The contribution of own food production to the nutrition of households in two neighbouring, rural, semi-arid settlements was investigated. A survey of a 10% probability sample (n=131) of households in Sekuruwe and Ga-Molekane in the Mokgalakwena Local Municipality, Waterberg District Municipality, Limpopo Province, South Africa, conducted in 2001, provided data on household composition, income ...

Japanese encephalitis (JE) is a disease caused by an arbovirus that is spread by marsh birds, amplified by pigs, and mainly transmitted by the bite of infected Culex tritaeniorhynchus mosquitoes. The estimated annual incidence and mortality rates are 30,000--50,000 and 10,000, respectively, and the estimated global burden of JE in 2002 was 709,000 disability-adjusted life years lost. Here, we d...

Rotylenchulus reniformis is the most damaging nematode pathogen of cotton in Alabama. It is easily introduced into cotton fields via contaminated equipment and, when present, is difficult and costly to control. A trial to monitor the natural migration of R. reniformis from an initial point of origin was established in 2007 and studied over two growing seasons in both irrigated and non-irrigated...

This paper analyzed dynamics of crop diversification in one of the agriculturally prosperous districts of Indian Punjab using Gibbs Martin Index. Spatio-temporal analysis of crop diversification in the district shows decline in crop diversification in most of the blocks (administrative sub divisions). The cropping pattern in most of the blocks of the district has become over specialized in the ...

sTUDIES of the liveweight gains of beef cattle have been undertaken at several places in North Queensland. These have included “Wairuna”, 50 miles W. of Cardwell, in a 28-inch rainfall area fairly typical of a large area of cattle country in North Queensland; the Bureau of Tropical Agriculture, South Johnstone, where cattle are grazed on tropical grasses and legumes grown under the high rainfal...

Background and Purpose: Water stress is one of the major problems for urban trees. It affects a wide range of plant responses, from changes at the cellular level to the reduction in growth rates. Irrigation of trees in urban areas may provide numerous benefits important for increasing tree vitality to withstand other stresses that might occur. The aim of this study was to compare drought effect...

Yield response of Nigella (Nigella sativa L.), also known as Kalonji, was compared under the treatments Nlevels (30, 60, and 90 kg ha -1 ) and nutrients mixture “Micro Power” applications (single, double and triple) as foliar spray (FS) during vegetative growth 60, 80 and 100 days after sowing (DAS). Field experiment was conducted at Agronomy Research area, the University of Agriculture, Peshaw...
