Abstract:
A field experiment was conducted to study the effect application methods of micronutrients on yield and Economics of linseed (Linum usitatissimum L.), at the Research farm, Bihar Agricultural College, Sabour, Bhagalpur during rabi, season of 2020-21. The experiment was laid out in randomized block design with three replications. The treatments consisted of nine micronutrient application practices. Result revels that application of RDF + foliar application of ZnSO4 @ 0.5% + foliar application of Borax @ 0.3% at 45 DAS (T₈) recorded statistically highest capsules plant^-1,seed capsule^-1, test weight (7.03 g), seed yield (1201.6 kg ha^-1) and straw yield (2308.6 kg ha^-1) which was statistically at par with application of RDF + Soil application of ZnSO4 @ 25 kg ha^-1 + Foliar application of ZnSO4 @ 0.5% at 45 DAS (T₄), RDF + Soil application of Borax @ 1.5 kg ha^-1 (T₅), RDF + Foliar application of Borax @ 0.3% at 45 DAS (T₆), RDF+ Soil application of Borax @ 1.5 kg ha^-1 + Foliar application of Borax @ 0.3% at 45 DAS (T₇) and RDF+ Soil application of ZnSO4 @ 25 kg ha^-1 + Borax @ 1.5 kg ha-1(T₉). However, none of the micronutrient treatments have significant influence on harvest index (H.I.) of linseed though maximum was recorded in T₈ (34.33%). Analysis of economics revels that highest gross return of Rs. 51474 ha^-1, net returns of Rs. 48622 ha^-1 and benefit-cost ratio was observed when RDF+ Foliar application of ZnSO4 @ 0.5% + Borax @ 0.3% at 45 DAS (T₈).
