  Kharif Crop

  • The crops that are sown at the beginning of rainy season i.e. between April & May known as kharif crop.
  • Major Kharif Crop- Rice, Maize, Cotton, Jawar, Bajra, etc.

Rabi Crop

  • Those crops that are sown at the end of monsoon or at the beginning of winter season i.e. between September & October.
  • E.g Wheat, Peas, Gram, Barley, etc.

Cultural Practices

Propagation in Rice Cultivation-
                                                                          Propagation is done through seeds.

Methods of Rice Cultivation:-

There are mainly four methods are used for rice cultivation.

Broadcasting Method-
  • In this method seeds are sown by hands.
  • This method is suitable for less fertile and dry lands.
  • It requires more labours.
Drilling Method-
  • Ploughing of land and sowing of seeds can be carried out.
Transplanted Method-
  • Seeds are sown in nursery bed.
  • When seeds are germinated (generally, 5 weeks) seedlings are transplanted to the main field.
Japanese Method-
  • This method is for high yielding hybrid crops.
  • This method needs higher doses of fertilizers.
  • Seeds sown on nursery bed and transplanted seedling in rows
Seed Selection-
  • Select those seed that have high yielding variety.
  • Seeds have to be clean and free from any other mixture of seeds.
  • The seed should be fully mature.
Seed Treatment-
  • For avoiding some borne disease use Agrosan 100gm/50 kg of seeds.
  • Wettable ceresan is a solution in which seeds should be soaked for 12 hours.
  • Dry them in shade.
Land Preparation-
Dry and Semi-dry System-
  • Ploughing and harrowing are used for good tilth.
  • Field needs FYM uniformly 2 to 4 weeks.
Wet System-
  • In wet system the land ploughed and puddled with 3cm to 5cm of water in the field.
  • Seeds sown on nursery and after few weeks seedlings are transplanted to main field.
Seed Rate-
  • Mainly, seed rate depends on the variety of seed.
  • Seed rate by broadcasting method is 90-100kg/ha.
Irrigation-
System of Rice Intensification "SRI" method use 120 to 150 lakhs litres of water per hectare to produce 7 tonnes of rice.

Weed Management-
Make your rice field free from weeds after 45 days of sowing.

Manure and Fertilizer-

  • Nitrogen: 100-150kg/ha.
  • Phosphorus: 50-60kg/ha.
  • Potash: 40-50kg/ha.
  • Zinc Sulphate: 25kg/ha.
  • Green Manure: Sanai, Urad, Dhaincha, etc.

Harvesting-

  • For medium varieties, 26 to 30 days after flowering.
  • For Tall Varieties, 36 to 40 days after flowering.

Yield-

          Average Yield is 2500 kg/ha achieved by good varieties.

Wheat

Origin-
              The origin of wheat is said to be south east Turkey.
In India, wheat originated in Southern Asia.

Geographical distribution-
                In India, U.P, M.P Punjab, Rajasthan, Bihar, Haryana, Maharashtra and Gujarat are some common states for rice production.

Economic Importance-
  • India's 2nd most consuming food is wheat.
  • It is staple food as well.
  • India produces 70 million tonnes of wheat per year.
  • It is approx. 12% of world production.
Soil-
       Clay loam or loam soil with good structure,texture and moderate(average) water holding capacity are suitable for wheat cultivation.

Climate Requirement-
  • Wheat is mainly a plant of mid-latitude grassland.
  • It requires 10ºC-15ºC in winter and 21ºC-26ºC  in summer with average rainfall.
Varieties-
  • T-aestivum cultivars, Durum and Emmer.
  • Important Varieties- Sonora 64 & Lerma Rojo, etc.

Cultural Practices

Season-
  • Wheat is a winter crop.
  • Sowing time is 15th October to 1st week of November.
Seed Rate-
           100 kg/ha.(average)

Field Preparation-
  • Cultivate field 2 to 3 times with cultivator.
  • Plough field 2 to 3 times with an iron  plough.
  • Prepare the land to a fine tilth.
Application of fertilizers-
  • 80:40:40 NPK kg/ha.
  • Nitrogen, Phosphoric Acid, and Potash are given basically before sowing.
Application of FYM or compost-
                On the unploughed field 12.5t/ha of FYM are needed.

Seed Treatment-
Seeds are treated by Carbennzium or Thiram at 2g/kg of seeds 24 hours before sowing.

Sowing-
  • Sow the seeds continuously in a line with distance of 20 cm apart.
  • Apply fertilizers before sowing at the depth of 5 cm.
  • Avoid deep sowing.
Weed Management-
  • Spray Isoproturon 800g/ha after 3 days of sowing.
  • Hand weeding is must on 20th and 35th day after sowing if herbicide is not applied.
Water Management-
  • 4-6 irrigation are needed depending on the soil type and rainfall.
Harvesting-
  • When grain becomes hard and straw becomes dry and brittle crops are ready for harvesting.
  • The cost of harvesting and winnowing are reduced through mechanical thresher.
Yield-

Cultivational Practices

Season-

It grown in almost all seasons with good irrigation system. 
Soil temperature is approx.18°C at the time of sowing.

Seed Rate-

  •  3-3.5 kg/ha by dibbling method
  • 4-5 kg/ha by drilling method.   
Spacing-
         40*10-15 cm.

  • Leaves will turn yellow and grain will be harden.
  • Dried Appearance.

Harvesting-

Cut the upper portion of plant(i.e. earheads) and leave the straw for a week for drying and cut it when straw has dry appearance.

Threshing-

 Threshed in a mechanical thresher or threshed by bullock carts.
