Package of Practices

1.

Season

:

Can be grown throughout the year as a multicut variety under irrigated conditions.

2.

Soils    

:

All types of soil with good drainage. Does not come up well on heavy clay soil or flooded or waterlogged conditions.

3.

Preparatory cultivation

:

Plough 2-3 times to obtain a good tilth. Form ridges and furrows of 6 m long and 60 cm apart. Spread 25 tones of FYM/ha before ploughing and incorporate well.

4.

Seed rate

:

5 kg / ha

5.

Spacing

:

30  x 15 cm (Sow on both sides of ridges)
60 x 15 cm ( For seed production)

6.

Fertilizers

:

Basal: 45 : 40 : 40 kg NPK/ha
Top dressing: 45 kg N at 30 days after sowing
After each harvest, apply 45 kg N/ha as basal.  
After first year apply 45:40:40 kg NPK/ha

7.

After cultivation

:

First weeding on 25-30 days after sowing. After each harvest a weeding may be given before fertilization

8.

Irrigation

:

Once in 7-10 days depending upon soil condition.

9.

Plant protection

:

Generally not needed. If shoot fly is noticed, spray Endosulphan 35 EC 500 ml/ha or Dimethoate 30 EC 500 ml/ha in 250 litres water. Plant protection sprays may be stopped one month before harvest of green fodder.

10.

Harvest

 

 

(i).

Fodder

:

First harvest 65-70 days after sowing and there after the ratoon crop may be harvested once in 50 days depending on flowering.

(ii).

Seed

:

110 – 125 days after sowing.

11.

Storage

:

Fed to cattle as green fodder or dry fodder and also ensiled.

12.

Yield

 

 

(i).

Green fodder

:

192 t/ha/year in 6-7 harvests

(ii).

Seed yield

:

1000 Kg/ha/year
Seeds can be harvested thrice in a year
Fresh seeds have dormancy for a period of 45-60 days and hence should be used for sowing only after 60 days.
