Abstract
The study on linseed aimed to investigate the effectiveness of fertilizer and organic spray of banana pseudostem sap or vermiwash on yield, quality, uptake and economics of the crop was conducted at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari during rabi season of 2019-20. The experiment was laid out in Randomized Block Design with four replicates. The experimental field was fairly leveled and uniform. The treatments comprising of 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).The result indicated significant differences on seed yield, oil yield and nutrient uptake in the seed and stover. Treatment T9 outperformed the other treatments by registering maximum yield, oil yield and nutrient uptake in the seed and stover, gross return, net return and benefit cost ratio. It could be concluded that to obtain better yield, quality, uptake and economics of rabi linseed crop the crop should be applied with 100% RDF(60-30-00 N-P2O5-K2O kg ha-1) and foliar spray of 1% vermiwash or 1% banana pseudostem sap at 30 and 60 DAS.
