Abstract:
Two field experiments were conducted at the Experimental Farm
of Faculty of Agriculture, Suez Canal University at Ismailia during 2008
and 2009 seasons to study the effect of nitrogen fertilization
and planting density on growth , yield, its attributes as well as seed
quality of new sesame variety (Taka 2 cv.). On newly reclaimed sandy
soils of Ismailia Governorate, Egypt, experimental design in split plots
form with four replications was used. Four levels of nitrogen
fertilization 55, 105, 155 and 205 Kg/ha were arranged randomly in the
main plots and three planting distances between hills (10, 15 and 20 cm,
respectively) were distributed at random in the sub plots. Increasing N
fertilizer level up to 205 Kg/ha significantly increased plant height,
fruiting zone length, height of the first fruiting branch, number of
branches and capsules/plant, 1000-seed weight, seed weight/plant, seed
oil content (%) and seed and oil yields /ha. Decreasing planting
distance from 20 to 15 and 10 cm consistently and significantly
increased plant height, height of the first fruiting branch and seed and
oil yields /ha. The reverse was true regarding the yield components.
These results were expected, since experiment soil was newly reclaimed
sandy soil and very poor in the nutrients and organic matter.
