Abstract
Background
This work was conducted to investigate the effect of different manure types (compost, chicken manure and FYM) at 12, 24 and 48 m3 ha−1 with or without reduced N rate (72 kg ha−1) compared with N fertilizer levels: 0, 36, 72 and 108 kg ha−1 under drip irrigation system. Therefore, field trials were established in the summer seasons of 2018 and 2019 on a private farm, Belbais District, Sharkia Governorate, in a newly reclaimed soil (loomy calcareous). Sesame seed yield, oil content and macro- and micronutrients were determined.
Results
Highly significant effects due to organic sources applied were apparent on seed yield and yield components. Yield response to FYM at the lowest rate compared to the other two sources and rates was evident. Correlation analysis of the various yield characteristics with N fertilizer application was reported. Fertilizer replacement value in manure sources ranged between 30 and 62%. The chemical analysis of sesame seeds indicated that chemical composition of sesame seed was insensitive to the type of soil amendment.
Conclusion
It could be concluded from this study that the predictable benefits from manure application to sesame will increase farmer confidence in organic fertilizers reducing the reliance up on inorganic fertilizers for crop nutrition and improving the sesame seed nutrient content.
