Abstract:
A field experiment was carried at Research Farm of Zonal Research Station, Assam Agricultural University, Shillongani, Nagaon during rabi season of 2019-20, 2020-21 and 2021-22 to validate the response of micro nutrients on growth and yield of linseed (Linum usitatissimum L) under limited irrigation. The experiment was laid out in randomized block design with three replications, consisting nine treatments: Recommended Dose of Fertilizer (RDF) i.e. 40- 20- 10 kg N-P₂O₅-K₂O/ha as Control (T₁), RDF + Soil application of ZnSO₄ @ 25 kg/ha (T₂), RDF + Foliar application of ZnSO₄ @ 0.5% at 45 DAS (T₃), RDF + Soil application of ZnSO₄ @ 25 kg/ha + Foliar application of ZnSO₄ @ 0.5% at 45 DAS (T₄), RDF + Soil application of Borax @ 1.5 kg/ha (T₅), RDF + Foliar application of Borax @ 0.3% at 45 DAS (T₆), RDF + Soil application of Borax @ 1.5 kg/ha + Foliar application of Borax @ 0.3% at 45 DAS (T₇), RDF + Foliar application of ZnSO₄ @ 0.5% + Borax @ 0.3% at 45 DAS (T₈) and RDF + Soil application of ZnSO₄ @ 25 kg/ha + Borax @ 1.5 kg/ha (T₉). Pooled estimation of three consecutive years revealed that application RDF along with Soil application of ZnSO₄ @ 25 kg/ha + Borax @ 1.5 kg/ha (T₉) as basal recorded highest plant population (7,89,890/ha), seed yield (803.78 kg/ha) as well as benefit cost ratio of 2.83.
