dc.description.abstract Nitrogen and phosphorus are two essential macronutrients for plant growth. Compost is used as a soil amendment to improve soil biological, chemical and physical properties. This experiment was conducted during the season 2016/17 in a riverine silt loam soil in a cooled plastic house located in the University of Gezira,Wad Medani, Sudan (latitude 140 24 N, longitude 31 ، 330E and altitude 411 masl). The climate is classified as semi arid .The objective of this study was to determine the effect of compost, combined with N and P fertilizers, on nutrient content, growth and yield of tomato , variety Termis and cucumber ,variety Leader. Sources of N and P were urea and TSP, respectively. The experiment was carried out in a spilt –plot design, with three replicates. The main plots were assigned to levels of the chemical fertilizers (0N/0P and 20gN+10gP2O5 /m2 applied at sowing .The subplots were assigned to levels of compost (0C and 2.5 kg compost /m2) which was banded in the soil before planting. The results showed that, application of compost alone or combined with the chemical fertilizers significantly(P≤0.05) increased K content of leaves and fruits of tomato. It also significantly (P≤0.05) increased nitrogen content of leaves of cucumber and fruits of tomato and P content of both leaves and fruits of tomato. The results also showed no significant differences at 15, 30 and 55 days after transplanting (DAT) of tomatoes due to application of both mineral and compost fertilizers or their combinations on plant height and number of leaves. However, data obtained at 45 DAT showed that, application of mineral fertilizers alone significantly (P≤0.05) increased growth parameters. Mineral fertilizers alone or combined with compost gave a highly significant increase (P≤0.01) in number of tomato fruits pre plant over that of compost and control treatments. The maximum number of fruits was obtained with the application of mineral fertilizer combined with compost. The application of compost alone significantly increased (P≤0.05) the number of fruits compared to that of the control treatment. A significant increase in yield was obtained due to separate applications of compost (P≤0.01) and chemical fertilizer (P≤0.05) over that of the control. Application of chemical fertilizers combined with compost showed high yield without significant difference over that of the treatment that received both compost alone or chemical fertilizers alone .The results of cucumber showed high significant increases (P≤0.01) in plant height, number of leaves and yield due to application of compost alone or combined with mineral fertilizer over that of the treatment that received the chemical fertilizers and control. It is recommended to apply compost with chemical fertilizers to increase yields of tomato and cucumber under greenhouse conditions. en_US
