Abstract
Oat (Avena sativa L.), a constitute of family Gramineae ranks sixth in world cereal production. The crop
is widely cultivated for use as food, feed and fodder. Being a highly nutritious cereal, especially rich in fat, protein,
vit.B1, phosphorous and iron, it is used for human consumption as well as for poultry, dairy cattle and other
animals. However, information regarding the regrowth and biochemical constituents in these species is not
available. Therefore, present study was done to find out the nutritive value of forage oat during single cut or
multicut management, grains of oat and the biochemical parameters responsible for regrowth of oat genotypes. For
this, fourteen oat genotypes were grown in field of forage research section of the Department of Genetics and Plant
Breeding following RBD. Plant samples were collected at 75 DAS and 50% flowering for multicut and at 50%
flowering for single cut and estimation of various biochemical parameters was done. Considerable increase in fresh
weight of the oat genotypes was observed at second cut. Two genotypes viz., HFO865 and HFO873 showed great
increase in fresh weight. Macronutrient and fructans concentration decreased progressively by 25-70 per cent with
advancement in plant age and is maximum in HJ-8 and minimum in OS-6.The cell wall constituents (NDF, ADF
and Cellulose) exhibited upward trend with the plant maturity. The content was found highest in HJ-8 in all the cut
management systems. Roots and stubbles of multicut genotype(HJ8) had high content of fructan, macronutrients,
micronutrient and carbon content than the single cut genotype (OS6). The study indicates that fructan,
micronutrients, macronutrients and carbon content playing an important role in regeneration of multicut genotype
(HJ8).
