IMPACT OF ORGANIC AND BIOFERTILIZER APPLICATION ON YIELD AND YIELD ATTRIBUTING CHARACTERS IN LINSEED (Linum usitatissimum L.)

Abstract

Linseed (Linum usitatissimum L.) belongs to family Linaceae, is the second most important rabi oilseed crop 
and stands next to rapeseed – mustard in area of cultivation and seed production in India. Flaxseed is grown as 
either oil crop or a fibre crop with fibre linen derived from the stem of fibre varieties and oil from the seed of 
linseed varieties.  Several studies have been conducted on effect of fertilizers on growth and yield of linseed 
(Linum usitatissimum L.) varieties which revealed their enhancing role on the quality and quantity of flax 
cultivars. In this regards, a present study  was planned and conducted during the Rabi season of 2020-2021 in 
the Agricultural field of School of Agricultural Sciences, Shri Guru Ram Rai University, Dehradun, 
Uttarakhand, India to investigate the effect of organic and biofertilizer and integrated treatment on the growth 
and yield of Linseed. The findings were reported on important growth and yield attributed parameters such as 
plant height, total fresh weight, total yield, 1000- seed weight (g), and number of seed / capsules. The maximum 
growth and yield was reported in T6 treatment where biofertilizer have been applied in consortium form 
followed by vermicompost. Thus, the findings revealed that all the microbial strains in consortia used as bio 
fertilizers showed enhanced tern of vegetative growth of plants, total herbage yield and total seed yield at 
various stages. This may be due to sustained release of nutrients to supply the required elements in microbial 
strains. The biofertilizers exhibited beneficial effects on plant growth and development either through producing 
growth hormones like IAA, kinetin and gibberellins, synthesizing atmospheric nitrogen and its increased 
availability to greater protein synthesis as well as increasing Phosphorus availability to plant communities. 
Thus, it was concluded that the enhanced expression of yield and its related attributes will have beneficial 
impact in production of nutraceutical products of commercial importance.
