Abstract EN

The present study was conducted during the growing season of 2013/2014 in the Medical and Aromatic Plants Unit Field, Agricultural Collage, Basrah University, to study the effect of sowing date and spraying with liquid hummus and their interaction on growth and yield seed and fixed yield of Khella plant Ammi visnaga (L.) Lam.

" Syrian Local " and its biochemical effects.

The study Included four factorial treatments, which were the combinations of two sowing dates 1/10 or 20/10 and spraying with liquid humus in concentration of 0.75 ml.

l.-1 or without ( spraying with distill water) for three times starting with 20 days after sowing for the first treatment and 20 days among spraying and their interactions.

A Complete Randomized Block Design in a factorial experiment was used with three replicates.

The results analyses with SPSS program and Least Significant Differences Test (L.S.D) in level 0.05 was used to compared The most important results may be summarized as follows -: Plants sowed on 1/10 gave a significant increase in plant height, total leaf number.

plant -1, number of main lateral branches.

plant-1 , earliest in the appearance of the first inflorescences, number of inflorescences.

plant-1, total seed yield.

plant-1 (45.3 gm), weight of 1000 seed, seeds productivity.

hectare-1 (4754kg), total fixed oil.

plant-1 (2.9gm), fixed oil productivity.

hectare-1 (309.5 kg), whereas plants sowed on 20/10 had a significant increases in dry matter percentage, fixed oil percentage ( 8.3%.) Plants sprayed with liquid humus had a significant increases in leaf number.

Plant - 1, dry matter percentage, number of inflorescences.

plant-1, total seed yield.

plant-1 (34.0 gm), seeds productivity.

hectare-1 (3543kg), fixed oil percentage (8.1%), total fixed oil.

plant-1 (2.6gm), fixed oil productivity.

hectare-1 (267.2 kg .) The Interactions between the study factors, showed a significant effect in all studded parameters
