| Abstract | ||
| Agreen house experiments were condacted to study the effect of four different levels of agricultural sulfur (zero, 1500, 3000 and 4500 )kg.Donm-1 on the soil sulfate content and on growth of two varieties of tomatos (Rakan F1and Eagen F1). Befor cultivation the soil fertilizers by (Urea46%, HighP (48%)and potas huomic) to level (25,25and 1) kg.Donm-1 The changes in soil pH was also studied .The number of the experintal units were 24 in a CRD experiment with three replicates . The experimental unit was (3 m2 )(1.5×2 m).divide into 3 rows ,the distance between rows( 1m) and the (40 cm) between plants. The sulfur stayed in soil (15) days before cultivation. The plants were irrigated by dropping till maturity (5 months). Result indicated that significant differences were obtained in the soil sulfate contents and the control (213,216 and 212 ppm SO4 ),in comparison with only ( 122 ppm SO4) .Also significant differences were found in chlorophyll content (%),TA% and T.S.S% both varieties when the level of S was 4500 kg .Donm-1 .The verity Rakcan was superier in T.S.S. % at level 1500 kg .Donm-1 S when compared to the variety Eagen in addition to that significant effects obtained in vitamin C and TA% content for Eagen variety at 4500 kg .Donm-1 . | ||
