TILLAGE OPERATION FOR FIELD CROPS

RICE (Oryza sativa L.)

Transplanted Puddled Lowland Rice
Wet nursery

Forming Seedbeds

  • Mark plots of 2.5m breadth with channels 30cm wide all around the seedbeds.
  • Length of the seed bed may vary from 8 to 10m according to soil and slope of the land.
  • Collect the puddled soil from the channel and spread on the seedbeds or drag a heavy stone along the channel to lower it, so that the seed bed is at a higher level.
  • Level the surface of the seedbed, so that the water drains into the channel.

Dry nursery

  • Dry ploughed field with fine tilth is required.
  • Nursery area with sand and loamy soil status is more suitable for this type of nursery.
  • Area 20cents.
  • Plots of 1 to 1.5 m width of beds and channels may be formed. Length may be according to the slope and soil. Raised beds are more ideal if the soil is clayey in nature.

Main Field Management
Land preparation

  • Plough the land during summer to economize the water requirement for initial preparation of land.
  • Flood the field 1 or 2days before ploughing and allow water to soak in. Keep the surface of the field covered with water.
  • Keep water to a depth of 2.5cm at the time of puddling.
  • Special technologies for problem soils:
  • For fluffy paddy soils: compact the soil by passing 400kg stone roller or oil-drum with stones inside, eight times at proper moisture level (moisture level at friable condition of soil which is approximately 13 to18%) once in three years, to prevent the sinking of draught animals and workers during puddling.
  • For sodic soils with pH values of more than 8.5, plough at optimum moisture regime, apply gypsum at 50% gypsum requirement uniformly, impound water, provide drainage for leaching out soluble salts and apply green leaf manure at 5 t/ha, 10 to 15 days before transplanting. Mix 37.5 kg of zinc sulphate per ha with sand to make a total quantity of 75 kg and spread the mixture uniformly on the leveled field. Do not incorporate the mixture in the soil. Rice under sodic soil responds well to these practices.
  • For saline soils with EC values of more than 4 dS/m, provide lateral and main drainage channels (60cm deep and 45cm wide), apply green leaf manure at 5 t/ha at 10 to 15 days before transplanting and 25% extra dose of nitrogen in addition to recommended P and K and ZnSO 4 at 37.5 kg/ha at planting.
  • For acid soils apply lime based on the soil analysis for obtaining normal rice yields. Lime is applied 2.5 t/ha before last ploughing. Apply lime at this rate to each crop up to the 5th crop.

Keep water to a depth of 2.5cm at the time of puddling

SYSTEM OF RICE INTENSIFICATION (SRI)
Mat nursery preparation

  • Preparation of nursery area:  Prepare 100 m2 nurseries to plant 1 ha.  Select a level area near the water source. Spread a plastic sheet or used polythene gunny bags on the shallow raised bed to prevent roots growing deep into soil.

Main field preparation

  • Puddled lowland prepared as described in transplanted section
  • Perfect leveling is a pre-requisite for the water management proposed hereunder

WET SEEDED PUDDLED LOWLAND RICE

Wet Seeded Rice

  • On receipt of showers during the months of May - July repeated ploughing should be carried out so as to conserve the moisture, destroy the weeds and break the clods.
  • After inundation puddling is to be done as per transplanting. More care should be taken to level the field to zero level.
  • Stagnation of water in patches during germination and early establishment of the crop leads to uneven crop stand.
  • Land leveling has say over efficient weed and water management practices.
  • Provision of shallow trenches (15cm width) at an interval of 3m all along the field will facilitate the draining of excess water at the early growth stage.

Land levelling

DRY SEEDED RAINFED UN-PUDDLED LOWLAND RICE

  • Dry plough to get fine tilth taking advantage of rains and soil moisture availability.
  • Apply gypsum at 1 t/ha basally wherever soil crusting and soil hardening problem exist.
  • Perfect land leveling for efficient weed and water management.
  • Provide shallow trenches (15 cm width) at an interval of 3m all along the field to facilitate draining excess water at the early growth stage.

 DRY SEEDED RAINFED UN-PUDDLED LOWLAND RICE WITH
SUPPLEMENTAL IRRIGATION

    • Dry plough to get fine tilth taking advantage of rains and soil moisture availability.
    • Apply gypsum at 1 t/ha basally wherever soil crusting and soil hardening problem exist.
    • Perfect land leveling for efficient weed and water management.
    • Provide shallow trenches (15 cm width) at an interval of 3m all along the field to facilitate draining excess water at the early growth stage.
  • Pre-monsoon sowing is advocated for uniform germination.

 DRY SEEDED IRRIGATED UN-PUDDLED LOWLAND RICE

  • Dry plough to get fine tilth taking advantage of rains and soil moisture availability.
  • Apply gypsum at 1 t/ha basally wherever soil crusting and soil hardening problem exist.
  • Perfect land leveling for efficient weed and water management.
  • Provide shallow trenches (15 cm width) at an interval of 3m all along the field to facilitate draining excess water at the early growth stage.

 MILLETS
SORGHUM (Sorghum bicolor)

Nursery Preparation
For raising seedlings to plant one hectare, select 7.5 cents (300 m2) near a water source where water will not stagnate.

Laying The Nursery
i.    Provide three separate units of size 2 m x 1.5 m with 30 cm space in between the plots and all around the unit for irrigation.
ii.   Excavate the soil from the inter-space and all around to a depth of 15 cm to form channels and spread the soil removed on the bed and level.

Main Field Preparation for Irrigated Crop

Ploughing
Plough the field with an iron plough once (or) twice. Sorghum does not require fine tilth since it adversely affects germination and yield in the case of direct sown crop.

To overcome the subsoil hard pan in Alfisols (deep red soils) chiselling the field at 0.5 m intervals to a depth of 40 cm on both the directions of the field followed by disc ploughing once and cultivator ploughing twice help to increase the yield of sorghum and the succeeding blackgram also. This was true with Sorghum followed by Groundnut also.

Application of FYM and 100% of recommended N can also be followed. In soils with sub-soil hard pan, chiselling should be done every year at the start of the cropping sequence to create a favourable physical environment.

Formation of Ridges and Furrows
i.    Form ridges and furrows using a ridger at 6 m long and 45 cm apart
ii.   Form irrigation channels across the furrows
iii.   Alternatively, form beds of size 10 m2 and 20 m2 depending on the availability of water.

RATOON SORGHUM CROP
 
RAINFED SORGHUM
Field Preparation
Test the soil and apply fertilizers based on soil test recommendations.

  • Chiseling for soils with hard pan Chisel the soils having hard pan formation at shallow depths with chisel plough at 0.5 M interval, first in one direction and then in the direction perpendicular to the previous one once in three years. Apply 12.5 t FYM or composted Coir pith/ha besides chiseling to get an additional yield of about 30% over control.
  • To conserve the soil moisture sow the seeds in flat beds and form furrows between crop rows during inter cultivation or during third week after sowing.

CUMBU (Pennisetum glaucum (L) R. Br. )

  • Form ridges and furrows (using 3 ridges) 6 m long and 45 cm apart. If pulses is intercropped, form ridges and furrows 6 m long and 30 cm apart.
  • If ridge planting is not followed, form beds of the size 10 m2 or 30 m2 depending upon water availability.
  • Form irrigation channels.
  • To conserve soil moisture under rainfed condition, sow the seeds in flat and form furrows between crop rows during intercultivation on third week after sowing.

RAGI (Eleusine coracana)

IRRIGATED

Preparation of Nursery (Irrigated Transplanted Crop)

Preparation of Land

  • For raising seedlings to plant one ha of main field, select 12.5 cents (500 m2) of nursery area near a water source, where water does not stagnate.
  • Mix 37.5 kg of super phosphate with 500 kg of FYM or compost and spread the mixture evenly on the nursery area.
  • Plough two or three times with a mould board plough or five times with a country plough.

Forming Raised Bed

  • Mark units of 6 plots each of size 3 m x 1.5 m. Provide 30 cm space between plots for irrigation.
  • Excavate the soil from the interspace and all around to a depth of 15 cm to form channels and spread the soil removed from the channels on the bed and level.

Preparation of Main Field

Ploughing the Field

Plough twice with mould board plough or thrice with wooden plough till a good tilth is obtained.

Forming Beds and Channels

RAGI : RAINFED

Tillage
            Fall ploughing is advantageous for moisture conservation.
