Micro-Irrigation Articles

Micro-irrigation with treated wastewater has the potential to be the most efficient irrigation technique, especially in water scarce areas. Its main disadvantage is the high sensitivity of the drippers to clog. This study focused only on the chemical precipitation mechanisms. In a batch chemical process in parallel with PHREEQC software, two temperatures (22 and 55°C), four pHs (8, 8.5, 9 and ...

This study employs the positive mathematical programming (PMP) approach to estimate groundwater derived demand for irrigation using a cross-sectional dataset of 200 predominantly groundwater irrigated farms from the Punjab province of Pakistan. First, we find that the PMP optimal solution uses less water than what is available (being extracted) in order to make farmers allocate all the ...

Bangladesh is losing huge food production from the Teesta catchment area due to a lack of availability of irrigation water in the dry and lean period because of unilateral water withdrawal in the upstream country, India. The area, which is directly dependent on the irrigation water of the Teesta river, is the study area for this paper. The study reveals that rice production in Dalia, ...

This paper presents results from the first study that focuses on water resources availability and demand for different purposes in the four oil-rich provinces of southern Iraq. The region accounts for 23% of the surface area and 18% of the country's population, but holds 88% of its oil. A water shortage of 430 Mm3/year for 2010 is estimated for this region where irrigation accounts for 81% of ...

This study applies contingent valuation to assess farmers' willingness to trade irrigation water. We analyse farmers' willingness to pay for water and their willingness to accept the selling of water through a seasonal market, under both normal rainfall and drought conditions. A survey of 241 farmers (irrigators and non-irrigators) in the Guadalquivir River Basin and in the ...

North China Plain is one of the most important grain-producing areas in China. Because of unevenly distributed precipitation in this semi-arid area, crop production largely relies on underground blue water (UBW) to irrigate, overexploitation of which causes a lot of environmental problems. In this paper, we first defined the representative division of winter wheat irrigation water production ...

Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut ...

Rise in temperature is one of the predicted impacts of climate change with significant implications on water resources management. An attempt has been made to calculate the water requirement of crops in different agro-ecological zones of Palakkad district in humid tropical Kerala using the CROPWAT 8.0 model. Sensitivity analysis was done for a simulated rise in temperature from 0.5 to 3.0 ...

Maize ( Zea mays L.) crops were grown at Coimbatore in the years 2009 and 2010 during the kharif season. The treatments imposed were three soil moisture levels: 100% irrigation water supply (0.8 IW/CPE ratio), 75% irrigation water supply (0.6 IW/CPE ratio) and 50% irrigation water supply (0.4 IW/CPE ratio). The plant density treatments adopted were normal spacing (60 × 20 cm), narrow ...

Agriculture in Gujarat has grown rapidly over the last decade, driven at least partly by diversification to high value crops and dairying. High value agriculture requires better water control and offers higher returns for irrigation. Farmers, farm communities and the state government in Gujarat have responded to this requirement by implementing large-scale water supply and demand management ...
