ABSTRACT
The present investigations entitled “Effect of organic manures, fertilizers and nitrogen scheduling
on growth and yield of Linum usitatissimum L. ” were carried out in the experimental field as well as in
laboratory of the Department of Forest Products, College of Forestry, Dr Y S Parmar University of Horticulture
and Forestry, Nauni, Solan (HP) during 2019-2020 and 2020-21. In the first experiment “Morphological studies
of Linum usitatissimum”, it was observed that linseed is an annual herbaceous plant which ranged 52.8 – 75 ±
5.33 cm in height. It had an erect, cylindrical and smooth stem with a short tap root system. The inflorescence
was raceme and the flowers were actinomorphic, hermaphrodite and terminal. The fruit type was capsule with a
persistent calyx and seed of was flat, pointed at one end and 3.9- 5.23 mm in length. In the second experiment
“effect of organic manures, fertilizers and nitrogen scheduling on growth and yield of Linum usitatissimum” it
was observed that application of treatment combination N4F2 (30 kg basal dose of N + 15 kg N at the time of
flowering + 15 kg N at the time of capsule filling + vermicompost @ 5 t/ha) gave best results with respect to
growth and yield. It resulted in maximum height (73.87 cm), maximum number of branches per plant (5),
maximum number of capsules per plant (115.93), highest seed yield per plant (4.7 g). The economic analysis of
Linum usitatissimum resulted in maximum B:C ratio in N4F3 (30 kg basal dose of N + 15 kg N at the time of
flowering + 15 kg N at the time of capsule filling + jeevamrit) because the cost of cultivation of this treatment
combination was less.
