Four experiments were conducted in Khartoum State in 2013 and 2014. The main objectives were to study the effect of a new bio-activator and organic fertilizer ‘’Elixir’’ on growth and yield of cucumber, tomatoes, and Abu Sabien as well as testing the soil conditioning ability of the product. The two sites of cucumber and their combined results showed that application of Elixir (1.0 l/tunnel/week) in combination with NPK (1.0 kg 10:50:10 and 1.0 kg 10:10:35/tunnel/week), up to end of the crop, gave significantly high number of fruits/m2 (123) and yield (10.53 kg/m2 ) under cooled plastic house conditions compared to foliar fertilizer combined with NPK (high P and high K), Elixir alone and the control NPK (20:20:20) alone, all at the same rate. Results of Elixir applied as a soil conditioner at the rate of one liter per standard plastic house per week, up to end of the crop, on growth, productivity and quality of tomato, Lycopersicon esculentum Mill., fruits under cooled plastic houses was remarkably better compared to other soil conditioners, Humic acid, EM and Clean salt. Elixir application resulted in significantly high yields (145.5 t/ha) by tomato variety Newten. Significant reductions in the soil electrical conductivity (Ece.) were recorded by different application rates of Elixir: 5 ml, 10 ml, 15 ml, 20 ml and 25 ml, (2.7 to 2.9 dSm-1) compared to the control (3.4 dSm-1).
