Title

STUDY OF AGRONOMICAL PROPERTIES OF LOCAL POPULATION OF CUMINUM CYMINUM L. IN DIFFERENT NITROGEN FERTILIZING LEVELS

Pages

  213-223

Abstract

 In order to study the effect of NITROGEN levels on yield, Physiological characteristics and essential oil content of CUMIN seeds, an experiment was conducted in research farm of Qazvin agriculture instruction center in 2006. The experiment was laid out by adopting split plot design with four replications. Main plots were NITROGEN (30, 60, 90 and 120 kg/ha) and subplots were local seed populations gathered from Sabsevar, Bojnord and Esfarayen. Results showed in using 120 kg NITROGEN/ha the highest SEED YIELD (801kg/ha) essential oil yield (16.99 kg/ha), (19.59cm) and seed number /m2 (19400) were obtained. The highest HARVEST INDEX as 45.08% belongs to 30 kg NITROGEN/ha. Esfarayen with 765.6 kg/ha, HARVEST INDEX 45.25 and 2.52% essential oil content was the best treatment. Sabsevar had the highest plant high and Bojnord had the highest biologic. SEED YIELD and essential oil yield of Esfraen with using of 90 kg NITROGEN/ha was 828 and 20.3 kg/ha respectively.
