Abstract
Two field experiments were conducted at the experimental farm of Sakha agricultural research station, ARC, Egypt during 2005/206 And 2006/2007 growing seasons to study the effect of Nitrogen, Calcium And Boron fertilization on growth, productivity and quality of sugar beet under different planting pattern.
1- Beets of 80 cm-2 side pattern accumulated the greatest dry matter. Increasing nitrogen rat increased accumulated dry matter / plant, Also application of B and Ca significantly increased dry matter accumulated / plant.
2- beets of 50 cm – 1 side pattern produced the highest top, root and sugar yields per plant and Fadden, increasing nitrogen level from 90 to 120 kg N/fad. significantly increased top, root and sugar yields. Application of B and Ca fertilizer had a significant effect on these characters.
3- planting pattern revealed on significant differences in TSS, soluble non sugar, extractable white sugar and looses sugar %, while beets of 50 cm -1 side pattern produced the tended to decreased TSS content, but it increased soluble non sugar, application of B and Ca significantly influenced TSS %. N, B and Ca fertilizer had no significant effect on extractable white sugar % and looses sugar % .
Generally, from the obtained data it can be concluded the plant population of 51.600 ants per Fadden distributed on one side of ridges 50 cm apart with 120 g N/fad. And application (1.5 kg B+ 100 kg Ca/fad.) could be recommended for optimum root and extractable white sugar yield per unit area at Kafr El-shaikh governorate.
