Abstract
Abstract A plastic pot experiment was conducted during the fall season of 2023-2024 in the College of Agriculture research station. To study the effect of Conocarpus residues in reducing the effect of saline water and N P K concentration, the growth and yield of onions irrigated with saline. The study included two factors: the first was the levels of Conocarpus residues with four levels, namley O0 (without addition), O1 (5 μg h −1 ), O2 (10 μg h −1 ), and O3 (15 μg h −1 ), while the second factor was the salinity of irrigation water with four levels: W1 (1.1 dS m −1 ), W2 (2 dS m −1 ), W3 (4 dS m −1 ), and W3 (6 dS m −1 ). The experiment was designed according to the Split-plot design using three replications. The main plots were occupied by the saline water treatments, while the sub-plots were occupied by the organic matter levels. The results of the study showed a significant increase in soil organic matter content, dry weight, bulb weight, total yield, and NPK absorbed by the plant as well as a significant decrease in electrical conductivity value and soil reaction degree (pH) coincides with increasing levels of Conocarpus residues addition, while increasing levels of salinity of irrigation water caused a significant decrease in soil reaction degree, soil organic matter content, dry weight, bulb weight, total yield, and NPK absorbed by the plant. The results also showed a significant decrease in all the above characteristics at a depth of 30-15 cm compared to a depth of 0-15 cm.
