INTRODUCTION INTRODUCTION Water shortage in has necessitated
the development of efficient water use methods for growing major crops.
In traditional agronomic and water use practices (Irrigated puddled paddy fields), the farmers apply much more water for paddy crop than the actual requirements.
INTRODUCTION INTRODUCTION Growing paddy on beds and furrows is
an alternate, which utilizes much less water.
In Pakistan water efficiency of rice under bed and furrow systems increased to 0.39 kg/m3 of water compared to 0.20 kg/m3commonly obtained under the traditional flood irrigation method

OBJECTIVEOBJECTIVE
Determine the effects of bed and furrow irrigation system on growth, production and water use efficiency of lowland rice.
Specific Specific Objectives Objectives Determine the effect of bed and furrow
irrigation system on growth and yield of lowland rice
Determine the WUE of the bed and furrow irrigation system for lowland rice
Optimize the design of bed and furrow method of irrigation to maximize, water saving and crop yield

CONCLUSIONCONCLUSIONThe irrigation method did not have a
significant effect on growth measured height and number of tillers over time.
Weed density was significantly higher in the bed and furrow systems compared to the basin
Crop water use efficiency higher in the bed furrow system vs. the basin.
CONCLUSIONCONCLUSION The yields did not differ
significantly between the f bed furrow system and the basin for the lowland varieties (Basmati 370 & IR2793.
The bed furrow systems evaluated did not show significant differences for most parameters evaluated.
CONCLUSIONCONCLUSION
To overcome the scarcity of irrigation water and generate higher crop yield, the bed and furrow method could be recommended for paddy cultivation
CONCLUSIONCONCLUSION
However, more field investigations are required
To refine to the configurations of bed
and furrows and rice planting system
To quantify amount of water saved
Cost benefit analysis – Establish benefits of Bed and furrow system vs Basin.
