Advantages and dis advantages of 2-wheel tractors

Advantages and dis advantages of 2-wheel tractors

The advantages of 2-wheel tractors are:

1. Multi-purpose vehicle

2. Operate in harder conditions than animals or humans

3. Operate in both wet and dry conditions

4. Fairly simple mechanical design

The disadvantages are:

1. Cost of owning and operating

2. Operator fatigue, although ride-on versions are now available.

Importance and types of farm power

Importance and types of farm power

i) Draft animals: Land preparation, weed management, crop threshing and transport are all undertaken using animal power. Oxen or buffalo are the most popular animal power source for agricultural practices in Maharashtra.

ii) Human power: Many operations like land preparation including ploughing, soil leveling and constructing levees and drains, plant establishment, pest control, crop harvesting and transporting, grain processing are undertaken on the farm by using human power.

Wetland Tillage

Wetland Tillage

1. Under wetland system the land is prepared by puddling for planting wet rice. Puddling means mechanical manipulation of saturated soil with standing water in the field.

2. The optimum depth of puddling is about 15-20 cm in the clay and clay-loam types of soils.

3. Good puddling means soil should be soft, uniformly levelled without weeds or stubbles and with minimum percolation.

Upland tillage

Upland tillage

1. The field is ploughed and harrowed to fine tilth taking advantage of summer rains and early monsoon showers.

2. Application of gypsum at 1.0 t/ha is recommended whenever soil crusting and soil hardening problem exists.

Secondary tillage

Secondary tillage

Secondary tillage implements are used for breaking clods and producing a loose, friable, smooth state. Secondary tillage is done for destruction of soil, stirring the soil and forming mulch, mixing the manures and fertilizers with soil and for covering the seeds.

Secondary tillage implements:

1. Cultivators

2. Harrows

3. Spike tooth harrow

4. Chain harrow

5. Disc harrow

Tillage

Tillage

Tillage refers to the mechanical manipulation of the soil with tools and implements so as to create favourable soil conditions for better seed germination and subsequent growth of crops.

On Season tillage: It is done during the cropping season (June- July)

Off season tillage: It is done during fallow or non-cropped season ( Summer)

Harvesting of Rice Crop

 

1. Harvest the crop when more than 90% of the panicles have turned to a hard dough stage.

2. Thresh paddy immediately after the harvest.

3. While drying, paddy should not be dried continuously for more than 4-6 hours at a time, in order to avoid cracking and to minimize breakage in milling.

Land Preparation

Land Preparation

1. Land preparation typically involves ploughing, harrowing, and levelling the field to make it suitable for crop establishment.

2. Draft animals, such as oxen, 2-wheel tractors or 4-wheel tractors can all be used as power sources in land preparation.

3. The initial soil tillage can also be performed with a rotavator instead of a plough.

Irrigation and Interculture

 

1. Limit the level of water in the plots to 2.5 cm during the first 10 days and increase the water level to 5.0 cm during the rest of the growing period and reduce the water level from 5cm to 2.5.cm 10 days before harvesting.

2. Tillering to panicle initiation is the important critical stage of crop growth.

Use of Zinc Sulphate in Main Field

1. Apply 20 kg zinc sulphate per hectare to the soil once in three season / crop.

2. Use of blended urea: If urea is used for top dressing, it can be cured as follows; Mix 10kg urea on 50-100kg loamy soil, sprinkle water just sufficient to moist.

3. Heap and keep the mixture for curing for 24 hours. Drain out water in the main field and broad cast the cured urea evenly.

4. Let in water to the field after 24 hours. The blended urea can be applied in two stages i.e. first in 15 days after transplanting and second application will be at panicle initiation stage.

Wet Nursery

 

1. Area required is the same as in the case of dry nursery.

2. Nursery area should be well puddled, levelled and kept weed free.Have adequate water for irrigation and drainage as needed.

3. Provide adequate fertilizer for each 100 sq. meter area (about 1000 sq.ft.) of nursery bed, provide 1kg N, 0.4 kg P2O5 and 0.5 kg K20. Double the P2O5 content in locations where cool temperatures retard the growth of seedlings.

Dry nursery

 

1. Raise nursery in about 750m2 areas to provide seedlings for one hectare area.

2. Prepare 75 seed beds of 25 feet long, 4 feet wide and 4 inches high.

3. Apply 25kg farm yard manure or compost along with 125g urea or 450g. Ammonium sulphate (90g N), 280 g single super phosphate (45g. P2O5) and 75g.

4. Muriate of potash (45g. K2O) or any other equivalent fertilizers for each bed. Sow the treated seeds equally in all the beds.
