Time of sowing

Situation for sowing varieties/hybrids

Time of sowing

I. Rainfed

a. Herbaceum varieties (Jayadhar/DDHc-11 etc.)

July -September

b. Arboreum varieties (DLSa-17)S

May - July

c. Hirsutum varieties/hybrids (Inter specific and Intra hirsutum)

May - 15th July

II. Irrigated

a. Hybrids

May - 15th July

b. Summer cotton

February - March

Note: Early sowing in the season is recommended for higher yields.

  • In Ghatprabha area during summer, take up the sowing from first fortnight of March to first fortnight April.

Planting geometry

Planting geometry can be modified and adopted based on soil type and fertility. Following planting geometries have been recommended under different soils and various growing situations.

1. Rainfed situation (For varieties)

60cm x 30 cm or 90cm x 20 cm

2. Irrigated ( For varieties and summer cotton )

75 cm x 30 cm ( Average soils) 90 cm x 30 cm (Fertile soils)

3. Transitional Zone (Zone-8, Assured rainfall areas for Hybrids)

 

    a. Interspecific hybrids

90 cm x 60 cm

    b. Intra hirsutum hybrids

90 cm x 60 cm or 90 cm x 30 cm

4. Heavy rainfall tract (zone 9 -Malanad) and Irrigated areas

 

    a. Interspecific hybrids

90 cm x 60 cm (Average fertility soils)

 

90 cm x 60 cm or 90 cm x 30 cm

    b. Intra hirsutum hybrids

120 cm x 60 cm (Fertile soil)

Note : Maintain  spacing depending on the soil fertility statuts.

Sowing:

  • Incorporate organics (FYM/Compost/Crop residues) into the soil 2-3 weeks before sowing.
  • For rainfed cotton apply entire recommended nutrients as basal at the time of sowing.
  • Under assured rainfall conditions, apply 50% N, entire dose of P2O5 and K2O as basal at the time of sowing and top dress remaining 50% N at 60 DAS.
  • Under irrigated conditions, apply 50 % N & K2O and entire P2O5 as basal at sowing and top dress 50 % N & K2O at 30 DAS and remaining 25% N & K2O at 60 DAS.
  • Under irrigated conditions in Zone -3, apply 25 % N & K2O and entire P2O5 as basal at sowing and top dress 50 % N & K2O in three equal splits at 50, 80 and 110 DAS.
  • Under heavy rainfall areas (Malanad), apply N, P2O5 and K2O in three equal splits i.e. Basal, 60 and 90 DAS.
  • In all the situations give foliar sprays of 2% Urea or DAP + 1% MOP at 80, 100 & 120 DAS
