Abstract

An experimental study was conducted to understand the response of various inter-row spacings and levels of plant growth regulators on yield attributes and yield of linseed during rabi season of 2021 which was laid out at crop research farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The soil of the experimental field was sandy loam in texture having pH of 6.9, organic carbon of 0.91%, available nitrogen at 301.26 kg/ha, available phosphorus 37.23 kg/ha and available potassium at 271.47 kg/ha. It consisted of different levels of plant growth regulators such as Gibberellic acid (125 and 250 ppm) and Indole acetic acid (1 and 3 ppm) and two spacings (20 cm × 5 cm and 30 cm × 5 cm), respectively. Overall nine treatments were developed along with consideration of control plot as one of the treatments. Finally, the experimental study concluded that maximum number of capsules (49.93/plant), test weight (7.14 g), seed yield (1.48 t/ha), stover yield (3.19

Conclusion

On the basis of the research work conducted in one season, it is concluded that treatment combination of 20 cm × 5 cm + GA3 at 250 ppm was found to be beneficial for obtaining higher seed yield.
