| Abstract | ||||
| Egypt considers the biggest imported food oils country in the world especially sunflower oil. A field experiment was carried out to study the influence of two organic fertilizers (biochar and poultry manure) applied by two methods (mixed and lined addition) and three nitrogen rates (0, 40 and 60 kg fed-1) on sunflower plant growth, yield, yield component and nutrients uptake. The experimental design was split split block design. Plant height, head diameter (cm), seed weight plant-1 , 1000 seed weight, stem diameter (cm),leaves number plant-1, straw and seeds yields (kg fed-1), oil percentage, oil yield (kg fed-1), harvest index (%), biological yield (kg fed-1) and nutrients uptake by straw and seeds were determined. The obtained results indicated that all the previous parameters significantly increased by all used treatments except harvest index and phosphorus uptake by seeds where it decreased with biochar and poultry manure. In addition, the combination between 40 kg N fed-1 and biochar gave the highest 1000 seed weight value (54.35g) while, the maximum seed yield value (2296.7 kg fed-1 ) was occurred with the treatment of biochar applied by mixed method at the rate of 40 kg N fed-1 without any significance over the combination of poultry manure, lined addition method and 60 kg N fed-1. The highest oil yield (927.7 kg fed-1) was recorded with the combination between poultry manure, mixed adding methods and 40 kg N fed-1 without significance over the treatment of biochar, mixed method and 60 kg N fed-1. It could be concluded that adding both poultry manure and biochar by mixed and lined methods improved sunflower oil yield, seeds yield and nutrients uptake. | ||||
