| Abstract | ||||
| A field experiment was conducted during the successive season of 2004/2005 winter in using clayey soil at Monshat El-Badawi Village, Talkha District, Dakahlia Governorate (North Nile delta region), to investigate the ability of applying farmyard compost and its compost tea on potato crop (Solanum tuberosum L.) cultivar Spunta and economic return for each treatments. Five treatments were arranged in a complete randomize block with three replicates, Four application methods (ore compost, sediment, sediment and extract combination and compost tea). Compost tea, foliar significantly increased dry shoot yield and fresh tuber yield in both seasons. Also, application of compost tea increased dry matter (as %), crud protein (as %) and specific gravity of tubers in both seasons. As so, sediment and extract combination addition increased dry matter (as %) in tubers, and crud protein (as %) significantly in both season.. The addition of farmyard manure into the soil increased both of total and available nitrogen, phosphorus and potassium in the soil. In spite of the highest values for all studied parameters under investigation were realized due to the compost tea treatment. | ||||
