EFFECT OF COMPOST, HUMIC ACID AND NITROGEN FERTILIZER RATES ON: 1- GROWTH OF SUGAR BEET CROP
Two field experiments were carried out at Hafeer Shehap El-Deen, El Khashaa Region, Kafr El-Sheikh Governorate, during the two seasons of 2010/2011 and 2011/2012 to study the effect of compost (0, 2, 4 and 6 t/fed), humic acid (0, 2 and 4 kg/fed) and nitrogen fertilizer rates (40, 60 and 80 kg N/fed) on growth of sugar beet cv. Gloria. Each rate of compost was performed in separate experiment. Every experiment of compost rates was carried out in split plot design with four replications. The main plots were occupied with rates of humic acid. The sub-plots were devoted with nitrogen fertilizer rates. The obtained results could be summarized as follows:
1. Organic fertilized sugar beet plants with 6 tons compost/fed produced the maximum averages of all growth characters at the period of 120 and 150 days from sowing (DFS) in both seasons. Followed by using of 4 tons compost/fed then 2 tons compost/fed at 120 and 150 DFS in both growing seasons.
2. Using the highest rate of humic acid (4 hg/fed) was more effective than other studied humic acid rates in increasing all studied growth characters at 120 and 150 DFS and produced the highest values in both seasons.
3. Fertilizing sugar beet plants with 80 kg N/fed significantly increased all studied growth and markedly recorded the highest values of these characters in both seasons.
It can be concluded that organic fertilizing sugar beet using 6 tons compost/fed beside 4 kg humic acid/fed and mineral fertilizing with 80 kg N/fed to maximizing its growth under the environmental conditions of Kafr El-Sheikh Governorate.
