| Abstract | ||
| Two Iysimeter experiments were carried out during 2001 and 2002 seasons at EI-Gemmeiza Agricultural Research Station, to study the effect of two organic fertilization treatments (farmyard manure and chicken manflre) and three nitrogen levels (0,30 and 40 kg Nffed.) as well as their interactions of yield, yield components and oil content of sunflower and some physical and chemical properties of Ihe different soils ( Clay. Loamy, Sandy and Calcareous) under the study. Split plot design with two replicates were used. The obtained results could be summarized as follows:- 1- Dry matter, plant height, head diameter, 100- seed weight and seed yield per fed. of sunflower were increased with chicken manure than farmyard manure for all soils under the present study. Also, all the previous Characteristics were increased by increasing nitrogen levels addition in all soils. 2- The highest values of dry matter, plant height, head diameter, 100-seed weight and seed yield per fed. were obtained from loamy soil with chicken manure at 40 kg Nffed. 3- Seed oil and seed protein percentage were increased with chicken manure than farmyard manure in all soils, except the clay one. Also, they were increased by increasing nitrogen levels addition in all soils, except the clay one where they were decreased at the highest nitrogen doses over than 30 kg Nlfed. 4- The highest value of seed oil percentage was recorded by clay soil with farmyard manure at 30 nitrogen unite, while the highest one of seed protein percentage was recorded by loamy soil with chicken manure at 40 nitrogen unit. 5· Chicken manure caused an increase in seed and straw nitrogen percentage than farmyard manure in all soils, except the clay one in seed nitrogen percentage and raising nitrogen levels caused an increase in seed and straw nitrogen percentage, except the clay one, the seed nitrogen was reduced after 30 kg N/fed. 6- The highest values of seed and straw nitrogen percentage were obtained from the loamy soil, coupled with chicken manure at 40 unite from nitrogen per feddan. 7 - Available soil nitrogen after harvesting was increased with chicken manure compared with farmyard manure in all soils, also the increase was found in soil available nitrogen after harvesting by raising nitrogen levels addition in all soils. 8· The highest value of available soil nitrogen was obtained from the loamy soil with Chicken manure at 40 unit nitrogen per feddan. 9- The values of bulk density were decreased and total porosity were increased with chicken manure compared with farmyard manure, also with increasing nitrogen levels addition, but hydraulic conductivity values were increased in clay and loamy soils, while they were decreased in sandy and calcareous ones. 10- The lowest value of bulk density and the highest one of total porosity were obtained from clay soil with chicken manure at 40 kg N/fed. , while the lowest value of hydraulic conductivity was obtained from the clay soil with farmyard manure at zero nitrogen level. | ||
