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 ...

The Indus Basin Irrigation System (IBIS) is more than a century old. Water allowances and canal water distributions responded to increasing crop water requirements in a southward direction, e.g. higher water allowance in Sindh as compared to Punjab. But within a province, the canal water supplies do not address the issue of difference in irrigation demand. The consequence is unprecedented ...

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 ...

“As we rely extensively on natural resources, our strategies help us to forecast future scarcity issues and ensure supply and demand is in balance. Our local reforestation programmes are good examples. We understand through local assessments, what fuels are used for curing our tobacco and it is vital to us to ensure that our farmers have a ready and sustainable supply available to them year ...

The aim of this study was to evaluate the antimicrobial and antioxidant potential of orange peel and seed extracts as additives to preserve quality of fresh–cut orange. Ethanolic extraction from seeds was fractionated in polar (PE) and non–polar (NPE) solvents, and essential oils from peels (PEO) were obtained. Total phenolics, flavonoids content, antioxidant activity, antifungal ...

This note is a partial response to the above mentioned 2010 Independent Evaluation Group (IEG) evaluation. It covers the specific issues to be addressed in the Water supply and Sanitation (WSS) sector and in the irrigation sector in two distinct parts, because if WSS and irrigation have some common features, there are many distinctions to be made. Among the various water-using sectors, that ...
