Abstract:
Field experiment was conducted to find out the effect of exogenous application of water-soluble fertilizers on growth, yield and economics of linseed (Linum usitatissimum L.) under Uterus ecology during rabi season of 2020-21 at research farm of Bihar Agricultural University, Sabour, Bhagalpur (Bihar) revealed that two times foliar sprays of NPK 19:19:19 @ 1.0% + ZnSO4 @ 0.5% at flowering and capsule development stage along with recommended dose of fertilizer (RDF) recorded highest seeds/capsule (7.98), test weight (5.56 g), seed yield (996.98 kg ha^-l), oil yield (360.60 kg ha^-l), gross return(63727₹ ha^-l) whereas seed protein content (10.63%) and B:C ratio (1.84) were recorded significantly highest with the treatments of two sprays of Urea @ 2.0% + ZnSO4 @ 0.5% along with recommended dose of fertilizer (RDF) however, CGR (5.21 g/day/m²) and RGR (17.95‘000 g/g/day) at 60-90 DAS were obtained highest with the treatment of RDF + two sprays of NPK 13:0:45 @ 1.0% + ZnSO4 @ 0.5%. Whereas harvest index is non-significant among the all the treatments.
