Effect of Inorganic Fertilizer and Organic Foliar Spray on Growth, Yield Attributes and Yield of Linseed

Aims: To evaluate the effect of fertilizer and organic foliar spray on growth, yield attributes and yield of linseed.

Study Design: The experiment was laid out in randomized block design with four replications.

Place and Duration of Study: A field experiment was carried out at College Farm, N. M. College of Agriculture, Navsari during rabi season of 2019-20.

Methodology: The study comprised of nine different treatments viz., T1(50% RDF),T2 (50% RDF + Foliar spray of 1% vermiwash at 30 and 60 DAS), T3 (50% RDF + Foliar spray of 1% banana pseudostem sap at 30 and 60 DAS), T4(75% RDF), T5 (75% RDF + Foliar spray of 1% vermiwash at 30 and 60 DAS), T6 (75% RDF + Foliar spray of 1% banana pseudostem sap at 30 and 60 DAS), T7(100% RDF),T8 (100% RDF + Foliar spray of 1% vermiwash at 30 and 60 DAS) and T9(100% RDF + Foliar spray of 1% banana pseudostem sap at 30 and 60 DAS).

Results: From the results, it was observed that an application of 100% RDF + Foliar spray of 1% banana pseudostem sap at 30 and 60 DAS (T9) resulted in significantly higher values of plant height (63.37 cm at 90 DAS), number of branches plant-1 (6.94 at 90 DAS), number of capsules plant-1 (51.85), number of seeds capsules-1 (8.95) and seed weight plant-1 (1.89). Significantly higher seed yield (1157 kg ha-1) and stover yield (2051 kg ha-1) of linseed were observed with the application of 100% RDF + Foliar spray of 1% banana pseudostem sap at 30 and 60 DAS (T9).

Conclusion: It can be concluded that, application of 100% RDF (60-30-00 N- P2O5-K2O kg ha-1) + Foliar spray of 1% banana pseudostem sap or vermiwash at 30 and 60 DAS was found to be the most viable option for getting higher growth and yield in linseed.
