The study was carried out thru 7 July - 1 October of 2015 in a cooled plastic tunnel (29ºc Temperature and 85%, Relative humidity) at Al Bagair area, in the northern part of Al Gazera State, Sudan, to study the effect of organic (Elkhierat), bio-fertilizer (Elixir) and chemical (NPK) and some micronutrients ( Fe, Zn and B at 200, and 100 ppm, respectively) fertilizers and their combinations on growth, yield and quality of cucumber (Cucumis sativus L.) variety (Faten). The treatments were Elkhierat 1kg/m ) or NPK (12g/m ) alone and their combinations with Elixir (1kg + 12mL/m ) or micro nutrients (1kg + 12g/m ). Elkhierat was incorporated in the soil before sowing. Other fertilizers (NPK and micro-nutrients) were dissolved in water (1g/Liter) in addition to Elixir (1ml/Liter) and added to the plants accordingly to the varied treatments weekly. Magnesium sulphate (2kg) and calcium nitrate (2kg) each huose were added at the third week. The experimental design was a randomized complete block design [RCBD] with four replications. The growth parameters recorded were plant height, number of leaves and flowers per plant, whereas, the yield and fruit quality parameters recorded were number of fruits per plant. yield per plant, fruit weight, early and total yield per plant and per unit area in addition to fruit length and diameter for quality.
