Abstract:
An experiment was conducted during rabi season, October 2021 to February 2022at the Agronomy Main Research Farm of College of Agriculture under Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India to study the effect of row spacing and fertility level on yield and economics of linseed crop. The experiment was laid out in split plot design with three replications comprising of three row spacing in main plot (20, 25 & 30 cm) and five fertility levels in sub plot (0:0:0, 20:10:10, 40:20:20, 60:30:30 & 80:40:40 kg N:P₂O₅:K₂O kg ha^-1). The row spacing of 25 cm resulted in maximum grain yield of 617.8 kg ha^-1. Grain yield increased with increase fertility level up to 60:30:30 kg N:P₂O₅:K₂O ha^-1, beyond which it was not significant. Application of 60:30:30 kg N:P₂O₅:K₂O ha^-1 produced 134.3% higher grain yield than the control plot. Narrow row spacing of 20 cm resulted in the maximum yield of straw (1815.1 kg ha^-1) due to the highest plant stand. The fertility level of 80:40:40 kg N:P₂O₅:K₂O ha^-1 produced maximum quantity of straw (1919.8 kg ha^-1), which was statistically at par with the fertility levels of 60:30:30 and 40:20:20 kg N:P₂O₅:K₂O ha^-1. Maximum net profit of ₹ 16,577 ha^-1 was obtained from the row spacing of 25 cm. Maximum benefit-cost ratio of 1.70 was obtained from the crop receiving 60:30:30 kg N:P₂O₅:K₂O ha^-1.
