influence of planting patterns and nitrogen levels on growth and yield of canola

Abstract: Two field experiments were carried out at Ismailia Research Station during 2001/ 2002 and 2002/ 2003 seasons to study the effect of four planting patterns: with 40cm between ridges which were planting in hills spaced at 10 cm with one plant/ hill at one side of the ridge (P1), 20cm between hills with 2 plants/ hill on one side (P2), 20 cm between hills with one plant/hill on the two sides of the ridges (P3), and drilling in rows 40cm apart and thereafter, seedlings were thinned at 10cm apart within the row (P4) and three nitrogen fertilization levels (30,45 and 60KgN/fad) on growth, yield and its components as well as quality of “Serw 4” canola cultivar (Brassica napus.1).
The results indicated that canola plants grown on two sides /ridge and one plant/hill at 20cm apart, and 40cm row spacing were higher in number of capsules/ plant. seed yield/plant (gm). 1000-seed weight (gm). seed weight (gm), seed and oil yields fad (kg) compared with other spacing patterns. Nitrogen rates had significant effects on all estimated characters.increasing nitrogenlevels from 30, 45 to 60 kg N/ fad increased all estimated estimated characters i.e. number of capsules /plant, seed yield/ plant (gm), 1000-seed weight (gm), and seed and oil yields/ fad (Kg), except seed oil percentage. Which took the reverse trend.
The interaction between planting patterns and N levels significantly affected seed yield/ plant (gm). and 1000-seed weight (gm).
