Studies on size and halving of sugar beet steckling on phenology and seed yield

In this research the effects of size and halving of sugar beet steckling on stem length¡ number of main stem¡ shoot weight and seed yield were investigated. Experiment was conducted in 28 Dec. and 21 Feb. 2014 in field in split split plot design with 10 replications. Treatments were combination of three paternal HM5514¡ S1-24 and SB26 two levels of whole and sliced stecklings and three levels of size of stecklings. Results showed that root size had significant effects on stem length and seed yield. Where¡ the tallest of main stem of stecklings with crown diameter 1.71¡ 1.59¡ 2.29 and 2.44 cm were 60¡ 67¡ 99 and 114 cm¡ respectively. Results also showed that seed yield of of stecklings with crown diameter 3.39¡ 4.80 and 6.28 cm were 15.35¡ 22.64 and 31.13 gr¡ respectively. In addition¡ seed yield was reduced by slicing of steckling. However¡ total seed yield of 2 sliced steckling were significantly more than one whole steckling.
