STUDY OF GROWTH, YIELD AND CHEMICAL CONSTITUENTS OF CORIANDER PLANTS AS AFFECTED BY USING ORGANIC FERTILIZATION, AND SOME NATURAL SUBSTANCES.

This study was conducted during 2015/2016 and 2016/2017 seasons
at the experimental farm,. Fac. of Agric, Azhar Univ Assiut, Egypt. To
investigate the effect of organic fertilization namely cattle at 0, 10 and
20 m3/ fed and poultry manure at 0, 5 and 10 m3/ fed and also foliar
spray with three natural substances namely vitamin E at 0, 100 and
200 ppm, thiamine at 0, 50 and 100 ppm and amino acids at 0, 100 and
200 ppm, as well as, their interactions on branching, herb dry weight,
fruit yield, essential oil % and yield and N, P and K% of coriander
plants. The most results showed that fertilizing the plants with organic
Fertilization at all levels, mostly led a significant increase in number
of main branches / plant, herb dry weight/plant, fruit yield /plant and
/fed. Essential oil % and essential oil yield /plant and /fed. and the
examined elements N, P and K %. The application of poultry manure at
the high level ( 10 m3/ fed. ) proved to be more increasing in the
pervious traits than those obtained by other organic fertilization
treatments. However, foliar spray with the three natural substances at
all concentrations, mostly, resulted a significant augment in all studied
parameters. The highest values of branching, herb dry weight, fruit
yield /plant and /fed. and the element of K % were obtained by foliar

spray with thiamine at the high concentration ( 100 ppm), while the
use of amino acids at the high concentration ( 200 ppm) gave the
highest values of essential oil yield /plant and / fed. and essential oil
%, as well as, the percentages of N and P. Clearly, most of combined
treatments significantly increased these abovementioned characteristics,
comparing to untreated ones. Apparently, the maximum values of most
traits were given by the application of poultry manuer at 10 m3/fed
with thiamine at 100 ppm and amino acids at 200 ppm in comparison
with those obtained by other combination treatments. It could be
recommended to supply coriander plants with poultry manure at 10
m3/fed .and foliar spray with thiamine at 100 ppm and amino acids at
200 ppm to enhancing the growth and obtain higher production of
fruits and essential oil.
