Preparation of Soil
Soil- Well-drained, light to medium soils are suitable.
And is to be thoroughly ploughed. Small size graded channel cum bund could be of use for conservation of soil moisture.
Sowing
Rabi: September/October under rain-fed conditions early around the middle of September is the ideal time for planting. if soil moisture is available planting can be extended up to the first week of October. compaction of soil immediately after sowing will help in proper emergence and establishment of seedlings.
Seed Rate :3 kg/acre
Sowing Time – June-July (onset of monsoon) for Kharif and October-November for Rabi.
Spacing: 45 cms x 15 cms
Fertilizer application
During the last plough four tons FYM/acre can be applied.
20 kg N, 15 kg O2 P5 and 12 kg K2 O/ acre as basal dose and 15 kg N/acre as top dressing at 20-30 days after sowing.
Under irrigation fertiliser dose can be increased to 80N and 40 P kg/ha. N should be applied in two splits, 50% at sowing and 50% as top dose at 30 days after sowing.
If Zn deficiency is observed on standing crop spray ZnSo4 0.2% (2g/lit) twice or thrice at weekly intervals.
Irrigation
For successful crop, even under rainfed condition, one irrigation on 45 days after sowing is essential.
For irrigated crop, weekly irrigation for light soils and once in 15 days for heavy black cotton soils is recommended.
Irrigation at flowering and grain filling stage is essential for a better harvest.
