| description | Implemented a field experiment is conducted in one of the farmers fieldsat
the bank of the Euphrates River in Ramadi - Anbar Province in the autumn
season 2010 to study the impact of two important factors on the
productivity of crop sunflower products Vlami, Group I, levels of
irrigation, the irrigation 100% (full irrigation), 75% and 50 % of ready
water, and Group II levels of plant density, distributed as follows (53 333
and 66 666 and 88 888) plants / ha, use a split plot design with random
sectors, where the occupied levels of irrigation main plots and plant density
secondary pieces. From levels of irrigation the first treatment of irrigation,
has given the best area of leaf is 6743 cm 2 / plant and the top holds the
seeds of the amount of 3.896 tonnes / ha and the top of each of the
consumption of water amounted to 399 mm / season, as well as the amount
of water given to where the 499 mm / season and the highest coefficient of
yield calculated from the basin of evaporation and the highest coefficient of
yield calculated from the equation of Kalat , while the third irrigation
treatment gives the highest efficiency in the use of water amounted to 1.868
kg / m 3, the less amount of water given 246 mm / season. The plant density
is low plant density 53 333 plants / ha increase in leaf area, while densities 66,666 and 88,888 plants / ha gave an increase in the sum of seeds 4.502 and
3.536 tons / ha, respectively, and water use efficiency is 1.824 and 1.386 kg /
m 3 respectively> |
