Effect of organic manures and chemical fertilizers on foeniculum vulgare, mill and carum carvi, L

ABSTRACT

The effect of organic manures and chemical fertilizers on the vegetative growth and oil production and composition for both plants were studied. The experiments were carried out during two seasons of 2001/2002 and 2002/2003. Three concentration from each of farmyard manure, FYM [8,12 and 16 m[3] /fed], chicken manure, CM [0.8, 1.2 and 1.6 m [3] /fed] and mixed manures of FYM + CM [4 + 0.4, 6 + 0.6 and 8 + 0,8 m [3] /fed] were added at the time of soil preparation. The chemical fertilizers N and K were used as soil dressing two times after 50 and 75 days from planting. The results indicated that the use of FYM, 16 m [3]/fed treatment produced high vegetative growth and high fruit yield/fed in both plants as well as high values of NPK for fennel plant The high oil yield was produced from the use of the mixed treatment FYM + CM 4 + 0.4 m [3] /fed and by the use of CM, 1.2 m [3]/fed in case of fennel and caraway plants respectively. The dose of CM, 1.2 m [3] /fed with caraway also produce high values of NPK
