“…These result may be regarded to nitrogen role in encouraging plant cell for division, growth and elongation. These results are in line with those obtained by El-kady, et al,2010 andAwed (2010).Meanwhile, the interactions between treatments are significantly affected plant height where, it increased with the interaction between mixed method and organic fertilizers. The highest plant height value (231.5cm) was found with the interaction between adding mixed method and biochar.…”

“…The increase in 1000 seed weight may be due to the increase in plant height, leaf area, nutrients uptake and photosynthesis which stored in seeds as result of nutrients availability. These results are in agreement with those of El-kady et al,(2010). The interactions between treatments significantly increased the weight of 1000 seed where the combination between 40 kg N fed -1 and biochar gave the highest 1000 seed weight value (54.35g).…”

“…Data as shown in Table (4) illustrate that oil percentage and oil yield (kg fed -1 ) were significantly affected by all used treatments, where they increased with increasing nitrogen rate and the highest oil percentage and oil yield (kg fed -1 ) values (40.7% and 801.88 kg fed -1 ) were found with the nitrogen fertilizer rate of 40 kg fed -1 . These results are in line with those of El-kady et al,2010 andSincik, et al (2013) The interactions between all used treatments were significantly affected oil percentage and oil yield (kg fed -1 ) where oil percentage decreased with the biochar interactions except with the nitrogen rate of 60 kg fed -1 , it increased compared with the control. These results may be due to incomplete decomposition of biochar and low content of nitrogen.…”

“…On the other hand, many researchers stated that nitrogen fertilizers significantly increased sunflower plant height, dry matter, seed production, oil yield (Oyinlola et al, 2010;Sincik et al, 2013;Salih, 2013). However, other investigator found that seed oil percentage decreased with increasing nitrogen fertilizer rates (El-kady et al,2010 andAwed 2010). The study aimed to investigate the effect of biochar, poultry manure, nitrogen fertilizers rates and their adding methods on sunflower yield, yield components and nutrients uptake.…”

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.

In a two year experiment carried out on the organic research plots of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria. Two liquid organic fertilizers (ARATI NAWOZ {2.01% N} and ARATI BAJA {1.01% N}) and control were applied to four sunflower varieties (SAMSUN 1, SAMSUN 2, SAMSUN 3 and SAMSUN 4) during the late cropping season (July – Nov.) of 2016 and 2017 to evaluate their agronomic response. The experiment was laid out in a randomized complete block design using a 4 × 3 factorial arrangement in three replicates. Data were collected on plant height at maturity, head diameter and weight, weight and number of seeds per head, 100 seed weight and seed yield. The varietal effect was significant (P < 0.05) on head diameter and weight, and number and weight of seeds per head, and seed yield in 2016. However, during the markedly dry 2017, the varietal effect was not significant for any trait measured. Foliar application of ARATI NAWOZ significantly (P < 0.05) increased height at maturity, the weight of seeds and head per plant and seed yield relative to the control in both years. Significant Variety × Fertilizer interaction effect was also recorded on the height at maturity, head diameter and weight, and seed yield in 2016. SAMSUN 4 (975.6 kg/ha) produced significantly (P < 0.05) higher seed yield than SAMSUN 1 (789.82 kg/ha) and SAMSUN 2 (778.54 kg/ha) in 2016. The efficacy of the application of both fertilizers was on par for most traits in both years. On average, the application of organic fertilizers resulted in a 15.76 and 69.02% increase in seed yield relative to the control in 2016 and 2017, respectively. ARATI NAWOZ and ARATI BAJA appeared promising for sunflower production in the humid tropics.
