Cotton

Land Preparation
It is common to grow cotton without irrigation. Before planting, low-fertility soil in these areas is loosened with an M. B. plough (down to 15 cm), fertilized (deeper, 20–25 cm), and harrowed twice to three times.
Seed rate and spacing
seed rate - 3.75kg/ha Spacing - 90 x 45 cm, 90 x 60cm
Intercultural operation
Practise thinning 10–12 days after germination. Filling up gaps is accomplished by planting seedlings produced in plastic bags. At this point, first hoeing and thinning are also useful. At the third and sixth week stages, second and third hoeing, weeding, and earthing should be performed, respectively. Early clean cultivation aids in both the initial growth and development of crops and the eradication of weeds that harbour insects.

Irrigation Management
Because cotton cannot withstand too much moisture, drainage is crucial. ASM determines how often irrigation should be used, which might be every 20–25 days. In general, irrigation is important throughout the flowering and boll development stages after fertiliser application. 2-3 irrigations are necessary in kharif and 6 irrigations are necessary in rabi.
Weed management
Herbicides like Fluchloralin (1.0-1.5 kg/ha as preplant inclusion), Metolachlor (1.5-2.5 kg), and Pendimethalin (1.5-2.0 kg) are used to manage weeds in the row spacing. As a pre-emergence, use Alachlor (1.5-2.0 kg) or Diuron (1.0-1.5 kg/ha). One post-emergence application of a Quizalofop at 400–750gm/ha might be sufficient to control weeds if they are still present.
Climate & soil

Average temperature for cotton is 25 to 30 degrees Celsius. Little yearly precipitation is necessary for cotton growing.

The best soil for growing cotton is loose, medium-textured, and humus-rich. The main soil type is black cotton soil, which is alluvial. pH = 6.5 – 7.5

Insect pest management

American Bollworm

  1. Trichogramma chilonis, an egg parasitoid, is released inundatively at a rate of 2.5 ml per acre three times, spaced 15 days apart, starting 45 days after planting.
  2. Crop remnants should be removed and destroyed in order to prevent the pest from spreading to the next season.
  3. Apply any one of the following insecticides, such as Spinosad 45.0% SC 66-88ml/acre, Lufenuron 5.4% EC 240 ml/acre, or Chlorantraniliprole 18.5% SC 60 ml/acre, during the period of boll formation and maturation stage.

Pink Bollworm

  1. Use pheromone traps to track the activities of adult moths at a rate of 5 per acre.
  2. Spray any one of the insecticides, such as Chlorantraniliprole, 18.5% SC, Diflubenzuron, 25%WP, or Emamectin benzoate, 5% SG, at a rate of between 76 and 88 g/acre.

Spotted Bollworm

  1. Alternative crops have to be taken out.
  2. Infested squares and flowers are collected and removed.
  3. Spray either one of the following: Fipronil 5% SC 800ml/acre or Chlorantraniliprole 18.5% SC 60ml/acre.

Red cotton bug

  1. To reveal the eggs, plough the field.
  2. Spray 600 ml/ha of phosphamidon 40 SL.
Plant diseases management

Fusarium wilt

  1. After heavy summer ploughing, remove and burn any infected plant debris in the soil.
  2. Apply 4 t/acre of farmyard manure (FYM) or other organic manures.
  3. Carbendazim 50%WP at 1g/lit of water, spot drenching

Boll rot

  1. Adopt the ideal spacing.
  2. Apply fertilizer at the specified rates.
  3. Spray 1000 g/acre of copper oxy chloride, 200 g/acre of Carbendazim, or 800 g/acre of Mancozeb.

Alternaria leaf blight

  1. Remove and eliminate the plant remnants that are contaminated.
  2. During the summer, engage in deep ploughing.
  3. Keep away from seeds from diseased crops.
  4. Apply Propineb 70% WP @ 500g per acre

Bacterial blight

  1. Discard and remove the diseased plant debris.
  2. Remove the weed hosts
  3. Rotate your crops using non-host crops.
  4. Spray 100 grammes of Streptomycin Sulphate and 500 gms of Copper oxychloride per acre.
Harvesting & post-harvest management

From 105 to 111 DAS, 50% of the bolls begin to burst, and 4-5 pickings are made within 50 days during the early morning hours. To maintain quality, dried leaf mixtures should be avoided.
