MANAGEMENT PRACTICES UNDER SALINE WATER IRRIGATION |

| Abstract:
This work aimed at elucidating the impact of irrigation intervals on the growth and yield of maize under saline irrigation in pots. Moreover, the salt accumulutation and its distribution pattern under variable irrigation intervals and different irrigation systems in soils of various textures were studied. Data obtained declared that frequent irrigations generally result in higher absolute dry matter yields than under traditional irrigation. The results indicated than the increase in the irrigation frequency results in an increase of the absolute maize yield which is, however, much less than proportional when fresh waters are used. In addition, the irrigation at short intervals led to a much greater salt accumulation at the soil surface with respect to the relatively long ones. The variations in both the aerial and the radical parts of the plant showed to be the results of the variables under study in combination and not individually. The choice of increasing the irrigation frequency in the hope of increasing yield is not a good one in saline water management because the slight yield increase observed here doesn't compensate for the costs of changing the irrigation system. | |
