Abstract:
Field experiment was conducted on “Productivity and resource use efficiency of linseed (Linum usitatissimum L.) under conservation tillage and foliar nutrition in rice fallow” during 2018-19 laid out in a split-plot design with three replications. Six combinations of three methods of establishment namely, paira cropping, conservation tillage and conventional tillage and two varieties i.e., ‘Arpita’ and ‘Kartika’ were allotted to the main-plots and two foliar applications: water spray and 19:19:19 NPK (2%) + B (0.02%) spray before intiation of flowering stage to the sub plots. The soil was loamy sand, slightly acidic low in available N, high in available P₂O₅ and medium in available K₂O. The method of establishment and the variety influenced the growth parameters viz; plant height and LAI. Application of foliar spray induced flowering and increased capsules/plant, seeds/capsules as well as the yield of the crop. Linseed variety ‘Arpita’ under paira cropping supplemented with foliar application of 19:19:19 NPK (2%) + B (0.02%) at flowering produced maximum seed yield of 709 kg/ha and stalk yield of 2232 kg/ha. Variety ‘Arpita’ produced higher oil yield (259.1 kg/ha) than cv. ‘Kartika’ (224.8 kg/ha) and paira cropping recorded 253.2 kg/ha oil and 72.8 kg/ha protein.
