Abstract
A field experiment was conducted during rabi, 2021-22 at MARS, UAS Raichur, Karnataka to study the effect of split application of nitrogen and nano-urea supplementation on growth and yield of linseed (Linum usitatissimum L.). The results revealed that application of 100 % N (Two Splits - 50% N as basal + 50% N as top dressing) recorded higher seed yield of linseed which was found at par with the 75% N (Two Splits - 50% N as basal + 50% N as top dressing). The growth parameters, yield attributes and seed yield of linseed was significantly higher with two sprays of nano-urea @ 3ml /litre each at flower initiation stage and capsule development stage, which was found almost at par with the two sprays of 2% urea at flower initiation and capsule development stage. Economic analysis revealed that higher gross monetary returns and net monetary returns were noticed under the application of two sprays of nano-urea @ 3ml /litre each at flower initiation stage and capsule development stage.
