Tips on field Crops in Assam

Transplanted early Ahu Rice:

  • Field selection: Fields with guaranteed irrigation facilities should be chosen. Soils with a coarse to medium texture are ideal.
  • Nursery management includes placing seeds in plain water, stirring them thoroughly, and discarding those that float. Mid-February is the best time to plant seeds in a nursery bed. The land should be well puddled, and seedbeds of 1.25 m width and 10 m length (which can be expanded or lowered as needed) should be created, with a 30 cm spacing between beds. 20-30 kg cow dung or compost, 80 g urea, 80 g SSP, and 40 g MOP are to be put into each seedbed.
  • Seeds that have germinated well are seeded at a rate of 650 to 1000 g per bed. The seed required for one hectare of the main field is 40-45 kilogramme.
  • In the case of hybrid cultivars, seed should be planted at a rate of 250-300 g/bed, with a seed demand of 7.5 kg for transplanting a 1 ha area.

Wheat:

  • Prepare to vermicompost from coconut trash such as leaves, flower sheaths, and so on.
  • In a coconut orchard, fallow clean cultivation is practised.
  • If necessary, watering should be followed by the construction of a basin in the coconut trees.
  • Mulching should be done with coconut leaves, husk, or other organic materials.
  • Two irrigations at a depth of 6 cm have been advised for all agro-climatic zones. The first irrigation must be provided during the crop’s crown root initiation stage (20-25 days after planting), and the second during the crop’s heading stage (70-75 days after sowing). When the groundwater table is near 50 cm of the root zone, irrigation should be avoided.

Maize:

  • In the case of hybrid maize, it is not recommended to save seeds from the previous year’s harvest for planting in subsequent years. Seeds from composite cultivars, on the other hand, maybe saved for planting the following year with no discernible yield loss.
  • A well-drained sandy loam soil should be used, and the field should be free of waterlogging.
  • The best period to sow is from the middle of September until the middle of November.
  • Maintain a spacing of 60 cm between rows and 20 cm between plants.

Buckwheat:

  • The best season to sow in the Upper Brahmaputra Valley Zone is September-October, and the best period in the Lower Brahmaputra Valley Zone is October-Mid November.
  • The ideal seed rate is 20 kg/ha (2.7 kg/bigha) and row spacing is 30 cm.

Foxtail millet:

  • The optimal period to sow is from the middle of January through the middle of February (the best time is last week of January). The seed rate is 8-10 kg/ha, which can be increased to 15 kg/ha if spread sowing is used.
  • Rows should be spaced 25 cm apart.

Lentil:

  • HUL 57 (small seed lentil variety), Axom Masur 1 (SL 2-24), and Axom Masur 2 are three new types that have been approved (SL 2-28).
  • Sowing should take place between mid-October and mid-November, with a suggested seed rate of 30 kg/ha or 4 kg/bigha. The seeds should be placed in rows with a spacing of 25 cm between rows and 5-7 cm between seeds.

Rapeseed and Mustard:

  • Toria variants with 90-95 day durations are TS 36, TS 38, and M-27. Jeuti, TS 46, and TS 67 are three new cultivars suggested for late planting.
  • NRCHB – 101, PM 26 and PM 27 are the recently recommended Indian Mustard varieties with crop durations of 107 days.
  • The best seed rate for toria is 10 kg/ha (1.3 kg/bigha), whereas the best seed rate for mustard is 8 kg/ha.
  • Only for the Hills Zone is a seed proportion of 75:25 Toria + lentil mixed advised. For Hills Zone, a seed rate of 6-8 kg/ha is suggested as a pure crop.
  • The best period to sow is from the middle of October until the middle of November.
  • November. Early seeding aids in avoiding aphid attacks.
  • Rapeseed and mustard can be seeded as late as November 30 in highland conditions and as late as the third week of November in medium upland conditions in the Barak Valley Zone.

Linseed:

  • The best period to sow is from the middle of October until the middle of November. Sowing can begin in the Barak Valley Zone in December, following the harvest of Sali paddy. The seeding rate is 15-20 kg/ha. Row spacing should be 25 cm and plant spacing should be 10 cm.
  • It can also be planted in conjunction with Kharif rice as a relay crop.

Niger:

  • Sowing occurs in October (September to the middle of October for the Lower Brahmaputra Valley Zone).
  • For line sowing, the seed rate should be 8 kg/ha (1.1 kg/bigha) and for spread planting, the seed rate should be 12 kg/ha (1.5 kg/bigha).
  • The recommended spacing between rows is 25 cm, while the recommended spacing between plants is 5-7 cm.

Potato:

  • Toria variants with 90-95 day durations are TS 36, TS 38, and M-27. Jeuti, TS 46, and TS 67 are three new cultivars suggested for late planting.
  • NRCHB – 101, PM 26 and PM 27 are the recently recommended Indian Mustard varieties with crop durations of 107 days.
  • The best seed rate for toria is 10 kg/ha (1.3 kg/bigha), whereas the best seed rate for mustard is 8 kg/ha.
  • Only for the Hills Zone is a seed proportion of 75:25 toria + lentil mixed advised. For Hills Zone, a seed rate of 6-8 kg/ha is suggested as a pure crop.
  • Rainfed late seeded toria following sali paddy (rice-toria sequence) seed rate should be 13 kg/ha, which is 33% more than the typically recommended rate of 10 kg/ha.
