•  MoP:  100­-125 kg/ha.

•  Gypsum:  125 kg/ha.

•  ZnSO4 :  10 kg/ha.

1/3 urea and all other fertilizer should be applied during final land preparation. 2/3 Urea are equally  splited applied at 35­-40 DAS and 65­-70 DAS.


Time:  Robi: 15 October – 15 November.

Kharif­I: 15 February – April.

Kharif­II: July.

Method: 60-­75 cm X 25­30 cm spacing. But it can be sown as broadcasting.

Depth: 25-­35 cm.

Seed Rate: 25­-30 kg for grain/ha.

50 kg for fodder/ha.

Seed Treatment: Seed should be treated with Agrosan G.N. and Granosan M.

Intercultural Operation 

Gap filling: Gap filling is done at 7-­10 DAS.

Thinning: When plant attain a height of 5­-10 cm, it should be thinned out at 10-­15 DAS.

Weeding: 2 weeding can be done.

Earthing Up: The soil in between the line should be earthup at the base of plants.
