...age value of 0.19 kgm-3, water productivity of wheat ranged from 0.77-1.48 kgm-3 with average of 1.18 kgm-3, water productivity of maize ranged from 0.68-1.25 kgm-3 with average of 0.90 kgm-3 and average water productivity of onion crop ranged from 0.29-0.36 kgm-3, with average of 0.32 kgm-3. Water productivity of onion was lower compared to the values reported by FAO and others. Better wa...

... salinity and reduce the water productivity of major crops. Addressing these issues, a long term experiment (2000 to 2009) under wheat-maize (9 seasons each) cropping pattern was conducted on raised beds (with furrow spacing of 65 cm (Narrow Bed-NB), 130 cm (Medium Bed- MB) and 180 cm (Wide Bed-WB)), with controlled traffic regime emplaced, in comparison with traditional intensive cultivated flat basin (FB) for evaluating impacts on soil, crop and

...en seasonal rainfall and water productivity is very high (0.93). There is a strong correlation between seasonal rainfall and yield of barani wheat. The yield of barani wheat grown using chemical fertilizers varied from 0.41 to 3.21 t ha-1 represents an eight-fold variation in the wheat yield of last 10 years (1998-08). There were almost three years when the yield was higher than the mean yield and three years when yield was lower than the mean yield by around ...

... resource to ensure high water productivity. In order to cope with this situation, it is imperative to make use of available water resources more efficiently through high-efficiency irrigation systems (HEIs). The present study aimed to conduct the economic analysis of high efficiency irrigation systems in Punjab province of Pakistan. We also measured and compared the water productivity of modern and conventional-irrigated fa...

...e highest crop yield and water productivity were recorded 8,748 kg/ha and 3.74 kg/cm3 respectively under T2 treatment as compared to other treatment. Furthermore, the experimental and simulation results of present study concluded that the sides of raised-bed/furrow, where the ridge gourd was sown, received enough water to support the plant growth in all treatments and RBFI with raised bed size of 0.8 m was more water use efficient and suitable method for water...

...and practices leading to water productivity enhancement to address increasing irrigation water demand and declining water resources. One of such technology known as laser land leveling was introduced in Pakistan in 1980s. More recent introduction is of another water efficient technique known as The Alternate Wetting and Drying (AWD) technology evolved by International Rice Research Institute (IRRI). AWD intervention in conjunction with laser land leveling is m...

This study has illustrated some key guidelines for the appropriate installation and management of furrow bed irrigation method on farms, which may increase decision support and may lead to increased water productivity
