Title: Intercropping of oilseed crops with oat fodder under rainfed condition.

Presented by: Ms. Priyanka Amonge Major Advisor: Dr. J.K. Saikia

Roll No. : 2011-AMJ-23 Professor

ABSTRACT

Land utilized for fodder cultivation in Assam is very negligible i.e. only 3,000

ha(B.N.Chatterjee and P.K. Das,1989) and production of green fodder is also limited,

which is not at all sufficient for the livestocks.

Therefore, our aim is to increase green fodder production per unit of land per unit

time through suitable row proportion for intercropping oat fodder and oilseed crops

under rainfed condition.

Keeping the above mentioned objectives an experiment is to be conducted in ICR

farm AAU, Jorhat on a net area of 600 sqm approximately, total no. of plots 33 and

size of each plot 4m3m with 11 nos of treatments having 3 replication in

Randomized block design(RBD). Different treatments that are to be followed are

T1,T2 & T3 as sole crop oat, linseed and toria respectively . T4 = Oat + Linseed (1:1) ,

T5 = Oat + Linseed (2:1) , T6 = Oat + Linseed (2:2) , T7 = Oat + Linseed (3:1) , T8 =

Oat + Toria (1:1) , T9 = Oat + Toria (2:2) , T10 = Oat + Toria (2:2) ,T11 = Oat + Toria(3:1) .Observations before and at the time of harvest such as physiochemical

properties of soil and plant characteristics like plant height, plant populations, nos

of leaves/ plant, dry matter content, green fodder yield, siliquae/plants, Stover yield

etc.,
