Abstract
Pot experiment was carried out twice during the two successive seasons of 2014 and 2015 in sandy soil at Abu-Ghaleb, Giza governorate to study the effect of different levels of saline water irrigation and some mineral and organic compounds on tomato growth and total fruits yield. The important obtained results were as follows:
1- Effect of saline water irrigation:
• Saline water irrigation at 2000 ppm gave the tallest plant height, but the shortest value of plant height recorded with that plants which irrigated with water contained the highest salinity level 4000 ppm.
• The heaviest fresh and dry weight of whole plants were recorded with plants irrigated with 2000 ppm, while the lowest fresh and dry weight were found with those plants which irrigated with the highest salinity levels (4000 ppm).
• The widest leaf area was associated with plants irrigated with the lowest salinity level, i.e. 2000 ppm, but the plants irrigated by water containing 4000 ppm gave the lowest leaf area.
• The highest chlorophyll content was recorded with that plants which irrigated with water containing the lowest salinity level i.e. 2000 ppm, while the lowest chlorophyll content was found when plants were irrigated with the highest salinity level (4000 ppm).
• Increasing salinity level from 2000, 3000 up to 4000 ppm reduced significantly the percentage of nitrogen, phosphorus, potassium, and iron in tomato plant leaves.
• Increasing salinity levels from 2000, 3000 up to 4000 ppm increased significantly the percentage of sodium and proline in tomato plant leaves.
• When increasing salinity levels more than 2000 ppm the total fruit yield, marketable yield, average fruit weight, and fruit setting significantly decreased to reach its minimum by plants irrigated with water containing 4000 ppm.
• The heaviest unmarketable yield was obtained with using irrigation water containing 4000 ppm, while the lowest unmarketable yield resulted with using irrigation water contained the lowest salinity level (2000 ppm).
• Increasing salinity levels more than 2000 ppm led to increasing fruit firmness and titratable acidity.
• Increasing salinity level from 2000, 3000 up to 4000 ppm increased significantly the percentage of total soluble solids (T.S.S.), and Ascorbic acid in tomato fruits.
2- Effect of mineral and organic compounds:
• The tallest tomato plants were measured recorded by plants supplied with the molasses at rate of 200 kg/fed. while the shortest plants were with the controlled one.
• The supplement of the molasses at rate of 200 kg/fed. gained the heaviest fresh and dry weight of plant, followed in descending order by plants which received the molasses at rate of 300 kg/fed.
• The significant widest leaf area was with plants supplied with the molasses at rate of 200 kg/fed. While the narrowest leaf area was registered control treatment.
• The highest total chlorophyll content was measured with plants supplied with the molasses at rate of 200 kg/fed. When compared with all other treatments.
• Using the high rate of the molasses at rate of 200 kg/fed. gained the highest nitrogen, phosphorus, potassium and iron content in tomato plant leaves, while control treatment registered the lowest percentages for the previous elements.
• The least sodium and proline contents of leaf tissues were recorded with the supplement of the molasses at rate of 200 kg/fed. compared with the control which gave the highest contents of sodium and proline.
• The highest total fruit yield, marketable yield, average fruit weight, and fruit firmness were recorded by plants treated with molasses at rate of 200 kg/fed.
• The unmarketable yield, fruit setting and titratable acidity decrease to its minimum value when using the molasses at rate of 200 kg/fed. but the highest unmarketable fruit weight was produced by control treatment .
• Using the molasses at rate of 200 kg/fed. gained the highest of total soluble solids (T.S.S.), and ascorbic acid in tomato fruits., while that control treatment registered the lowest percentages for the previous elements.
3- Effect of interactions:
• The tallest tomato plants was showed by plants irrigated with the lowest salinity level (2000 ppm) and treated with molasses at rate of 200 kg/fed., while the shortest plants were noticed with that plants irrigated with the highest salinity level (4000 ppm) and control.
• The heaviest fresh and dry weight of tomato plant was showed by plants irrigated with water containing 2000 ppm and supplemented with the molasses at rate of 200 kg/fed., while the lowest fresh and dry weight was given by that plants irrigated with the highest salinity levels (4000 ppm) and control treatment.
• The biggest leaf area was noticed with plants which irrigated with the lowest salinity level (2000 ppm) and supplied with molasses at rate of 200 kg/fed. while the smallest leaf area was detected with that plants irrigated with saline water containing 4000 ppm and control.
• The highest value of total chlorophyll content recorded with that plants which irrigated by the lowest salinity level, i.e. 2000 ppm and treated with molasses at rate of 200 kg/fed. While the lowest total chlorophyll content recorded with that plants irrigated with the highest salinity levels, i.e. 4000 ppm and control treatment.
• The highest nitrogen, phosphorus, potassium and iron percentages in tomato leaves was recorded with plants irrigated with the lowest salinity level (2000 ppm) and treated with the molasses at rate of 200 kg/fed., while the least percentages were obtained by plants irrigated with the highest salinity level (4000ppm) and control.
• The highest sodium and proline contents in tomato plant leaves were noticed with that plants which irrigated with the highest salinity levels, i.e. 4000 ppm and without supplied non treated materials, while the lowest sodium and proline values were recorded with plants irrigated with the lowest salinity levels, i.e. 2000 ppm and treated with the molasses at rate of 200 kg/fed.
• The heaviest total fruit yield, marketable yield and average fruit weight, gained from plants irrigated with the lowest salinity value (2000 ppm) and treated with the molasses at rate of 200 kg/fed. While the lowest total fruit yield, marketable yield and average fruit weight were noticed with that plants receiving its irrigation water with the highest salinity level (4000 ppm) and control.
• The highest unmarketable yield and titratable acidity was produced from that plants irrigated with the highest salinity level (4000 ppm) and without using material, while the lowest was registered with that plants receiving its irrigation water was containing 2000 ppm with the molasses at rate of 200 kg/fed.
• The highest total soluble solids (T.S.S.) and Ascorbic acid in tomato fruits recorded with that plants irrigated with the highest salinity level (4000 ppm) and the control treatment. While the least percentages were obtained with that plants irrigated with the lowest salinity level (2000 ppm) with molasses at rate of 200 kg/fed.
