صProductivity of sunflower yield and yield composition under different drainage systems at Egyptian salt affected soils
Abstract: Salt affected soils are one of the more adverse media for the plant growth in world wide. These problematic soils conditions have negatively affect water and nutrients movement and uptake, thus seriously hampering crop production. Sunflower (Heliamthus annuus L.) yields became highly consumptive and needed for human and animals feed. In a middle north of Nile delta, this work was established under different drainage conditions to predict the yield of sunflower verities and their nutritional composition.
The obtained results show that tile drainage system was more efficient to reduce the water table depth, salinity and alkalinity conditions and increasing the values of saturated hydraulic conductivity comparatively with that of open drainage one. The content of macro and micronutrients in the studied soils were existed in sufficient amounts, consequently, the plants grown in these areas may be suffered from salt stress. Moreover, tile drained soils cultivated with the foreign sunflower variety (Fedok) were highly productive comparing with that planted by the local one (Giza 2). Besides, the obtained sunflower weight of (1000) seeds and oil% had a maximum values.
Simple correlation coefficients and regression equations were statistically computed to express the relationship between some soil properties under different drainage conditions and the nutritional elements content as well as sunflower oil yield.
The obtained results provide a promising option for the use of salt affected soils to produce oil seed crops, i.e., sunflower with supported and beneficial effect of tile drainage beside the use of improved plant varieties at the middle north of Nile Delta soils.
