Response of micro-nutrients on yield and economics of linseed (Linum usitatissimum L.) under limited irrigation

Abstract

A field experiment was conducted during Rabi season of 2019-20 at Oil Seed Research Farm of C S Azad University of Agriculture and Technology, Kanpur. The experiment consisted 9 treatments viz., T1: Control, T2: Soil application of ZnSO4 @ 25 kg ha-1, T3: Foliar application of ZnSO4 @0.5% at 45 DAS, T4: Soil Application of ZnSO4 @ 25 kg ha-1 + Foliar application of ZnSO4 @0.5% at 45 DAS, T5: Soil application Borax @ 1.5 kg ha-1, T6: Foliar application of Borax @ 0.3 % at 45 DAS, T7: Soil application of Borax @ 1.5 kg ha-1 Foliar application of Borax @ 0.3 % at 45 DAS, T8: Foliar application of ZnSO4 @ 0.5% + Borax @ 0.3% at 45 DAS and T9: Soil application of ZnSO4 @ 25 kg ha-1 + Borax @ 1.5 kg ha-1 in soil assigned in Randomized Block Design with three replication. The Linseed cv Shekhar was used in the experiment. The results in significantly maximum seed yield, oil content, oil yield and stover yield, Root development, minimum water use and ultimately higher seed yield and WUE as compared to other corresponding tested treatments indicated that application of ZnSO4 @ 25 kg ha-1 + Borax @ 1.5 kg ha-1 incorporated in the soil have fetched highest net return of Rs 52050 having B:C ratio of 3.51 would be quite remunerative for higher productivity along with water use efficiency in light textured alluvial soils of Uttar Pradesh.
