Background: Water in any form is the prime constitute of plant growth and development. Right amount water applied at right time quantity to crop will helpful get maximum yield potential that crop. This possible with surface drip irrigation method. Uniform application through emitters necessary aspect avail benefits like higher use efficiency irrigation. Uniformity system can be measured by vari...
Plots naturally infested with Rotylenchulus reniformis were sampled in the spring of 2006 and 2007 at depths of 15 and 30 cm in the bed, furrow over the drip tape, and "dry" furrow, and at approximately 40 to 45 cm depth in the bed and dry furrow. Then, 1,3-dichloropropene (Telone EC) was injected into the subsurface drip irrigation at 46 kg a.i./ha, and 3 to 4 weeks later the plots were resamp...
Providing the population with clean drinking water and agricultural water, which provides humanity food, has become one of main problems around world. In Republic Uzbekistan, as well in other countries world, shortage is growing every year. The article states that factors for mitigating shortages agriculture introduction water-saving technologies. Among technologies, most effective system drip ...
Water is essential for life. Specifically in the oases of inland arid basins, water is a critically limited resource, essential for the development of the socio-economy and the sustainability of eco-environmental systems. Due to the unique hydrological regime present in arid oases, a moderate groundwater table is the goal of sustainable water management. A shallow water table induces serious se...
Meeting the food needs of Africa's growing population over the next half-century will require technologies that significantly improve rural livelihoods at minimal environmental cost. These technologies will likely be distinct from those of the Green Revolution, which had relatively little impact in sub-Saharan Africa; consequently, few such interventions have been rigorously evaluated. This pap...
A drip irrigation delivery system was used to infest field sites with the plant-parasitic root-knot nematodes, Meloidogyne incognita. Juvenile or egg inocula passed through the system without blockage of emitters or harm to the nematodes. Field sites so infested were available for experimentation. Delivery of approximately 5 x 10 to 10 juveniles or 10 to 3 x 10 eggs per emitter through the drip...
abstract in order to study the effects of cultivation method and water quantities in drip irrigation on yield of potato, an experiment was carried out using a split plot based on randomized complete block design with 4 replications in torogh agricultural research station (mashhad, iran) for tow years (2001 and 2002). the main-plots were divided into 3 levels of irrigation: i1= 100, i2= 80 and i...
Drip irrigation is a new method of irrigation that is rapidly growing in different countries. The emitters are the most important parts of a drip irrigation system. Many factors such as physical, chemical and biological clogging, pressure, water temperature affect the emitter´s uniformity of water emission. In this study, to investigate pressure effect on the hydraulic performance of emitters, ...
