abstract this study was conducted to determine the impacts of plastic mulch, drip irrigation method and different amount of water and their interactions on yield, water use efficiency (wue) and quality characteristic of tomato (mobile cultivar). the study was conducted in torogh agricultural research station, razavi khorasan province. the study was done during 2007-2008. experimental design was...

The aim of this research was to study how water use management can increases vegetation cover inrainwater catchment systems. The study was conducted through comparison of two methods of irrigation, i.e. traditional sub-surface drip irrigation and drip irrigation. Three soil samples were taken and analyzed from three locations in north of Sistan from a depth of 50 cm. A furrow was dug with a bas...

In the southeastern U.S. Coastal Plains, supplemental irrigation is required to reduce the impact of short‐term droughts and yield‐reducing plant water stress that can occur at least biennially. Sprinkler irrigation is commonly used to water agronomic crops in the region. Microirrigation is typically used for high value fruit and vegetable crops. In recent years and at some locations, microirri...

Water management and utilization is an ongoing problem in developing countries with semi-arid to arid climates such as Afghanistan. The lack of effective irrigation systems are oftentimes the most limiting factor for maximizing agricultural productivity in these countries. In Afghanistan, the most widely used irrigation methods are basin/border for cereal crops and furrow for vegetables and gra...

Field experiment was conducted for 2 seasons to study the influence of drip fertigation in combination with or without bio fertilizers on yield, plant uptake and soil fertility of Bt cotton. The treatments comprised of four levels of drip fertigation viz., 75, 100, 125 and 150 per cent of recommended dose of fertilizers (RDF, NPK) combined with and without bio fertilizers, drip irrigation w...

The water use efficiency under conventional flood method of irrigation, which is predominantly practised in Indian agriculture, is very low due to substantial conveyance and distribution losses. Recognizing the fast decline of irrigation water potential and increasing demand for water from different sectors, a number of demand management strategies and programmes have been introduced to save wa...

Use of drip, or trickle, irrigation in agriculture has increased rapidly during the past 20 years. In 1970 approximately 50,000 ha in the United States were under drip irrigation, by 1985 the area had increased to over 300,000 ha (6). Irrigation has been used to deliver fertilizers and pesticides (8,9,14,18,27,28), and there are increasing numbers of studies on the application of nematicidal co...
