Abstract | ||||
Two field experiments were conducted during 200012001 and 200112002 growing seasons at the Agricultural and Veterinary Training and Research Station, King Faisal University. Results indicate thai the irrigation treatments significantly 3ffeded all e~fim~ted characters. except numbe. or brancneslplant. Irrigation canola every 7 days with the rate of SOO mJlirrigatiOnlha or every 14 days with the rate of 650 m3/irrigationlha resulted in increasing plant height, stem diameter, number of pods/plant. number of seeds/pod, seed oil percentage as well as seed and oil yieldsJha. Water use efficiency reached the highest value with the irrigation of canota plants every 14 days. Nitrogen rates had significant effeds on all estimated characters. The higher nitrogen rates (150-200 kg Nlha) were associated with an increase in all estimated characters, except seed oil percentage, which took the reverse trend. The interaction between irrigation tntervats and nitrogen rates had significant effects on seed and oil yieldslha. In general, it can be stated that Irrigation canota every 14 days and fertilizing with 200 kg N /he produced the highest seed and oil yieldslha. | ||||
