Effect of spacing and phosphorus levels on growth and yield of linseed (Linum Usitatissimum L.)

The experiment was conducted during the period from November to March, 2020-21 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj to study the effect of spacing and phosphorus levels on growth and yield of linseed. The variety Neelam was used as test crop during this experiment. It consists of two factors: Factor A: Spacing (3 levels); 20cm×10cm, 30cm×10cm, 40cm×10cm and Factor B: Phosphorus (3 levels); 20, 30 and 40 kg/ha. The experiment was conducted by following a randomized block design with three replications. The results revealed that treatment combination of Spacing at 20cm×10cm + Phosphorus at 40 kg/ha obtained highest in plant height (62.43 cm), dry weight (12.60 g), crop growth rate (5.00 g/m2/day), relative growth rate (0.013 g/g/day), seeds per capsule (8.46), capsule per plant (52.47), test weight (6.40 g), seed yield (0.82 t/ha), stover yield (2.36 t/ha) and oil content (38.47%) respectively. It may be defined that spacing and phosphorus had a significant influence on the growth and yield of linseed and spacing 20cm×10cm and 40 kg P per hectare can be the optimum dose for attaining higher yield.
