Fertilizer Application

30:30:0 kg NPK per ha

Weeding

Not needed but can be carried out 25-30 DAS

Weed Management

Not really needed as the crop is somewhat resistant to wheat naturally.

Irrigation

Usually Rainfed but 2-3 irrigations may be followed in higher altitudes

Earthing up and Hoeing

Not really needed but can be carried out during 20-25 DAS

Harvesting Index

60-70% seed hardened

Harvesting

Due to its indeterminate growth, the plant shows irregular development in its life and also within the population . If the harvest is delayed, seeds can shatter due to wind or be dispersed due to invading living organisms (birds, rats etc.). Due to its gradual formation and maturity of seeds, harvesting is done periodically and finally the crop is cut and then threshed when the rest of the seeds are fully matured

Post Harvest Activities

The seeds must be well dried. Over matured seeds when come in contact with high moisture, germinate quickly as the seeds have vivipary characteristics.

Similar to weeding time

Harvesting Index

The grains become hard and Dark brown in color

Harvesting

The plants are cut with sickle and threshing is done to separate the grains/seeds from plant.

Post Harvest Activities

Aphids- Spray Methyl Demeton @1000 ml/ha at pre flowering stage.
Ear caterpillars- Dust crop with Malathion 5% @ 25 kg/ha

Disease

blast caused by Pyriculariagrisea is the major problem (By growing resistant varieties like GPU 28, GPU 26 and GPU 48.
Treating seeds with fungicides like carbendazim @ 2g/kg a day before sowing
If necessary spraying the nursery with carbendazim (0.05%) or kitazin (0.1%) or Ediphefos (0.1%) or Saaf (0.2%)
Spray any of the above fungicides at 50 per cent flowering and repeat 10 days later if Kitazin or Ediphenfos were used to control neck and finger blast.)

Root-knot nematode
American pod borer
Termites(chlorpyriphos @ 0.9g a.i or endosulfan @ 2.4g a.i/kg seed, be taken up for their management. Seed treatment with thiamethoxam 70WS (Cruiser 70WS) @ 0.7 g a.i./kg seed or Fipronil (Regent 5FS @ 0.3 g a.i./kg seed) is also very effective.)

IPM
T.viride (@4g/kg seed) + carboxin (75WP @1.25g/kg seed) or tebuconazole (@ 1.0g/kg seed) for the control of loose smut, followed by broadcast of insecticide treated soil (with endosulfan 35 EC @ 2.3L or chloropyriphos @ 3L/ha) at 15DAS for termites. For the management of aphids, foliar spray of imidacloprid 200SL @20g a.i./ha on border rows at the start of the aphid colonization be given. This will help in protection of the bioagent insect, the lady bird beetle inside the field which feeds on aphids

Disease

Loose smut: [seed treatment should be done with T. viride @ 4 g / Kg seed in combination with carboxin (Vitavax 75 WP) @ 1.25 g / Kg seed or tebuconazole (Raxil 2 DS) @ 1.0 g / Kg seed. Seed treatment with T. viride alone @ 4 g / Kg seed is also helpful as it reduces the rust severity.]

Karnal bunt: [ one spray of propiconazole (Tilt 25EC) @ 0.1 % (1 ml in 1 Litre water) may be given (in seed crop only) at ear head emergence stage. Two sprays of biocontrol fungus, Trichoderma viride, one before ear head emergence, followed by another spray at ear head emergence stage, provide a non-chemical (biological control) management of disease. One spray of T.viride, followed by one spray of propiconazole (25EC) @ 0.1 % at ear head emergence stage can be given to attain near complete control. Similarly, two sprays of propiconazole, give complete control of KB.]

Powdery mildew: [ one spray of propiconazole (Tilt 25 EC) @ 0.1 % at ear head emergence or appearance of disease (whichever is earlier) is recommended for the powdery mildew prone areas.]
