Title : To study the performance of Co. 6415 under different levels of Nitrogen fertilisation.

Author : R .S.Sachan, A.T. Yaragattikar,P,Y,Keskar , R.G.Menon and H.L.Kulkarny.

Year : 1976-77

An experiment to study the performance of Co 6415 under different levels of Nitrogen fertilisation, with a view of fixing the optimum dose for this variety, was laid out at per details in Table VIII. Treatment C-200 Kg/ha of Nitrogen gave the highest CCS/ha.

Table VIII. Experiment Study of Responce of Co 6415 to Different Doses of Nitrogen.

Field No. A - 2/72

Variety : Co 6415

Replication : Three

Plot size : 59.5 Sq. M.

Date of Planting : 9th June 1976

Date of Harvesting : 30th May 1977.

Treatments : A No Nitrogen

B 100 Kg/ha Nitrogen

C 200 Kg/ha Nitrogen

D 300 Kg/ha Nitrogen

E 400 Kg/ha Nitrogen

F 500 Kg/ha Nitrogen

The above treatments were applied over a basal dose of 100 Kg/ha each of K2 O and P2 O5 at planting.
