A Simplified Irrigation Pump Testing Method for Developing Countries: A Case Study in Bangladesh. [PDF]
Abstract Much of South Asia experiences a monomodal rainfall pattern with a distinct dry season following the annual monsoon. Enabling irrigation during the dry season has therefore been crucial in assuring improved productivity and double‐cropping. This is particularly the case in southern Bangladesh, where recent government initiatives have called ...

Viewpoint: Irrigation water management in a space age
Abstract Climate change and rapid population growth are already putting increasing demand and pressure on the world's freshwater resources. Irrigated agriculture is responsible for about 70% of global freshwater withdrawals, consuming the most amount of water.

ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Development and Testing of a Low‐Cost Soil Moisture Sensor for Real‐Time Irrigation Scheduling
ABSTRACT Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder ...

Irrigation efficiency and optimization: the Optirrig model [PDF]
Developed by INRAE, Optirrig is a software tool for generating, analysing and optimising irrigation scenarios. It is based on a simplified description of plant growth according to the evolution of water and nitrogen resources in the soil. It compares the

ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Point of view - The search for maximum water use efficiency, an objective not to be disconnected from an integrated vision of the production system [PDF]
Drip irrigation, and more subsurface drip irrigation, are particularly popular techniques for irrigating crops in regions where water resources are a major constraint. However, as François Gontard of BRL Exploitation shows, installing this equipment does

Arrosage par aspersion des pépinières de palmier à huile en sacs de plastique. I. Doses et fréquences d'irrigation [PDF]
Les pépinières en sacs de plastique sont plus sensibles à la sécheresse que les pépinières en pleine terre car les réserves en eau de la motte sont plus faibles que celles du sol en place.

ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...
