Deficit Irrigation Crop water stress Daily night time spray irrigation
9. Deficit Irrigation
Some experimental results suggest that fruit trees established with adequate irrigation can thrive well with deficit irrigation at a later stage. If this is corroborated by further field trials, then the area under remunerative orchard crops may be increased gradually with the same amount of available water. This requires conceiving a long term plan where surface irrigation development is a remote possibility. This possibility has to be weighed against another experimentally established fact that partially wetted trees react more favorably to higher water application or fertilization.10. Crop water stress
This has a great role in reducing water use in water scarcity areas, but it also affects fruit dropping, out of season blossoming and fruit quality. In crop water stress management of Sirocco oranges it was found that a delay in the beginning of the irrigation season to the indicated limits will bring about a fruit drop which in each turn will reduce total yield by 11but will increase fruit size by seven percent. Also an average increase of 20 in water use efficiency can be achieved. There is a need to study degree of stress which should be carefully checked to avoid the risk of out of season blossoming and fruit quality.11. Daily night time spray irrigation
Was found in Italy to increase relative humidity and reduce maximum temperature of plots. Night time irrigation resulted in effective control of vapour pressure deficit during the day and significantly lowers evaporation than those during the day time application. Thus high frequency night time irrigation tends to provide more water saving than the weekly day time application. This needs regional study and confirmation. Main criteria of Adoption Issues They consist of ,cost of installation, water Saving:, Yield Increase, Quality of Produce, Study of Growth Components and Irrigation Scheduling and some current new concepts. Each of the issues have been discussed below1. Cost of Installation
