| 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 STUDY OF GROWTH, YIELD AND CHEMICAL422 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. | ||||
