Crop growth is impacted by soluble salts that determine the normalcy or salinity of soils and natural waterways. Salt-affected soils have a critical role in land deterioration in irrigated areas. In view of this, a field experiment was conducted in the 2020 and 2021 wet and dry seasons in the eastern and western sectors of the Kano River Irrigation Project (KRIP), Garun Mallam and Kura local government areas, Kano (11°45’N and 12°05’N; 8°45E’ and 9°05’E) in the Sudan savanna agro-ecology of Nigeria to evaluate the effect of organic manure on the growth and yield of tomato in the saline and sodic soils of KRIP. Treatments consisted of farmer practice, recommended fertilizer rates (100:30:30), poultry manure, and cow dung, which were laid out in a randomized complete block design in which a farmer constitutes a replication. Soil data (pre-planting and post-harvest) were taken, and plant data were taken on plant height, leaf area index, days to 50% flowering, number of fruits, fruit yield, and an economic analysis was performed to determine the profitability of the treatments. Plant height, number of fruits, and fruit yield show significant differences (P<0.05) with the application of treatments. Results showed that application of poultry manure increased plant height, the number of fruits, and fruit weight. However, leaf area index, number of days to 50% flowering, and number of days to first fruit were not significantly affected. Results also revealed that poultry manure was more economical when compared to the other treatments. The application of poultry manure was also found to increase the level of pH in the soil, reduce the electrical conductivity, and increase the effective cation exchange capacity as a result of the increase in Ca2+, Mg2+, and K+ in the exchangeable sites relative to Na+. It can be recommended that the application of organic manure in areas affected by salinity be encouraged for tomato production.
