Abstract:
The research was conducted
at the Agriculture Research Farm, Faculty
of Agriculture, University of Suez Canal,
during the sesame growing seasons of 2011
and 2012. For studying the impact of insect
pollination and nitrogen fertilization on
sesame production, the experiment was
divided to 13 treatments of open pollination
and non open pollination, with three
different levels of ammonium nitrate
(NH4NO3) and one level of seryalin as biofertilizer.
Non opened pollination treatments
were covered before the start of flowering
period with a perforated net bag, to allow
the air to pass through and to prevent insects
from approaching the plants. Quantitative
and qualitative indicators, were measured as
follows: rate of capsule per plant, capsule
weight, rate of seeds in each capsule, weight
of 1000 seeds, germination (%), seedlings
vigour and oil content (%). Results clearly
demonstrate that qualitative and quantitative
indicators of sesame crop was significantly
increased with opened pollination and with
the increase of nitrogen fertilizer level up to
40 kg N/ feedan-1 plus or minus seryalin, in
reclaimed sandy soils, in Ismailia, Egypt.
