Response of Camelina sativa Oil to Different Levels of N-P-K and Compost Fertilizers
This study was conducted during the two winter seasons (2018/2019&2019/2020) to investigate the effect of NPK and compost fertilizers on Camelina sativa plant under Egyptian ecology. The fertilizer levels of NPK were 0, 25, 50, 75 and 100%, recommended doses, whereas compost applied at 6, 8 and...

| Summary: | This study was conducted during the two winter seasons (2018/2019&2019/2020) to investigate the effect of NPK and compost fertilizers on Camelina sativa plant under Egyptian ecology. The fertilizer levels of NPK were 0, 25, 50, 75 and 100%, recommended doses, whereas compost applied at 6, 8 and 10 m3/ fed to investigate effect of these fertilizers and the interaction of both chemical and organic fertilizers on the vegetative growth, oil yield and oil components percentage, application of 100% NPK as well as 10m3 compost produced the highest mean values ofall vegetative characteristics compared to unfertilized plants at both samples in the two growing seasons and the other treatments. On the other hand, results showed that all NPK treatments 25, 50, 75, and 100% NPK significantly increased seed yield (g/plant) as compared to control, the mean values were 3.06, 4.70, 9.09 and 10.20g/ plant compared to 1.84g/ plant, respectively, for the 1st season and 3.11, 4.48, 9.27 & 10.27g/ plant comparing to 1.80 of control for the 2nd season. Compost treatments significantly increased seed yield, the mean values were 5.10, 5.72, 5.88 and 6.42 g/ plant in the 1st season and 5.09, 5.73, 5.99 and 6.32 g/plant in the 2ndseasonfor fertilization with 0, 6, 8 and 10m3/Fed., respectively. The maximum mean values were obtained by compost at 10 m3 /Fed. The interaction treatment between 100% NPK and 10m3/Fed showed the maximum mean value of seed yield which recorded 10.51 and 10.78g/plant for the 1st and 2nd seasons, respectively. In contrast, the lowest values of seed yield were obtained from unfertilized plant which recorded 1.09 and 1.04g/plant for the 1st and 2nd seasons, respectively. The promising effect of NPK fertilizer on fixed oil % and yield was evident with NPK100%, 52.53& 52.83%fixed oil % whereas yield was 408.63 and 413.68l/Fed.), followed by 75% NPK which produced fixed oil % and yield 46.82, 46.77% as well as 207.29 and 208.06 l/ Fedfor the first and second season, respectively, compared with other treatments and control. The highest fixed oil percentages and yield (l / Fed.) were recorded with NPK at 100% and compost at 10m3/ Fed during both seasons |
