Conteúdo: | A field experiment on effect of nitrogen (0,50 and 100 Kg n/ha and crop geometry 945 x 30 cm - 74149 plants/ha, 60 cm x 30 cm - 55500 plants/ha, 30-60 x 30 cm as paired row - 74149 plants/ha and 30-90 x 30 as paired row - 55500 plants/ha) and their combination was conducted at the University farm during 1982-83. Application of nitrogen significantly increased plant height, dry weight of shoot, LAI, number of filled seeds/head, 100 seed weight, seed, weight, LAI, head diameter, number of filled seeds, seed and stalk yield between 50 and 100 Kg level. Oil content in seed was decreased with increase highest with 100 Kg N application. Dry weight of shoot and LAI was higher with higher plant density. Test weight, number of filled seeds, oil yield and nitrogen uptake was higher at 30-60 x 30 spacing over other spacing treatments. Seed and stalk yield was highest at wider paired row planting (30-90 x 30 cm). There was not much variation in oil content among different crop geometry.
