EFFECT OF CULTIVATION MEDIA, IRRIGATION WATER SOURCES AND ORGANIC MANURE ON SOME WATER RELATIONS AND SOIL SALINITY UNDER PROTECTED GREENHOUSES
This investigation was conducted in plastic greenhouses at Sakha Agricultural Research Station to study the effect of cultivation media, irrigation water sources and organic manure levels on some water relations, soil salinity and total income under protected greenhouses condition .Split-split plot design with four replicates was used. The obtained results could be summarized as follows:
1- The highest amount of water applied to cucumber and tomato crops were recorded with rice straw bales irrigated by fresh water, while the lowest values were recorded with clay soil irrigated by well water.
2- The highest irrigation water and water use efficiencies were achieved with rice straw bales for cucumber or clay soil for tomato as cultivation media, which irrigated by fresh water and treated with the rate of 20 tons/fed organic manure.
3- Salinity levels were increased after harvesting of cucumber in the 1 st season with the all treatments especially that irrigated by well water and treated by high rates of organic manure under clay soil. On contrary, salinity levels were decreased with all treatments at the end of the second season (tomato) ,especially with rice straw bales treated by low rates of organic manure and irrigated by fresh water.
4- The total incomes that obtained from cucumber and tomato grown in clay soil irrigated by fresh water and treated by high rates of organic manure were higher than those obtained with rice straw bales irrigated by low quality water without application of organic manure.
