Abstract
Two field experiments were conducted on clay loam soil at Battera village.
Talkha district. Dakahlia Governorate. Egypt. during the two successive growing seasons of summer 2003 and winter 2003/2004 to study the effect of tow sources of sulfur application rates (0. 150kg S fed" as elemental sulfur 99.5%S and as gypsum 16.60% S) under rice straw compost application (0, 6, 12 ton fed") on potatoes (Solanum tuberosum, L.) cultivar Spunta and some soil properties. The experimental design was a split plot design with three replicates.
The obtained results showed that
Addition of sulfur (S) and Compost (C) and their interactions significantly increased plant heighl (em), leaf area (m2 plant"), total chlorophyll and fresh and dry tuber yield (I fed") both seasons.
Soil physical properties were markedly affected with both of sulfur and compost applications whereas, bulk density decreased and increased total porosity %. Saturation percentage increased significantly with compost but it was not affected by sulfur application.
Application of sulfur and compost significantly increased available (NH:-N. N03'- N), P and K as compared with control in bolh seasons.
Finally, from the present study we can recommended that application of 150 kg S fed" as element + 12 ton compost fed" of rice straw with the constant background of recommended doses of (NPK) for improving the production of potato under similar experimental conditions.
