Spacing
Generally, sowing is done at 23 cm row spacing in north Gujarat on sandy or Goradu soils. Wheat sown at 23 cm apart in cross manner in dry soil and than irrigated also gives good germination and higher yield.
Seed rate
Normally seed rate is depends on the size or weight of seeds. Less seed rate is require, if the seed size is small.
1) Small seeded varieties like J-1-7, Kalyansona and GW-40 requires low seed rate of 100 kg seeds/ha.
2) Bold seeded varieties like J 24, J 18, Sonalika, Lok 1 etc. require 125 kg seeds/ha.
3) Seed rate should be kept 25 per cent higher than recommended seed rate under late sown conditions.
Seed treatment
Seeds should be treated with fungicides like Captan or Thiram @ 3 g per kg of seeds for controlling soil borne diseases like root rot and seedling rot.
In areas having light, sandy and Goradu soils where termite is a serious problem, the seeds should be treated with Endosulphan (700 ml for 100 kg seeds) or Chlorpyriphos (450 ml for 100 kg seeds) in 5 l of water. Treatment should be given at previous night and treated seeds should be dried over night period and used for sowing in next day morning. If seed treatment is not possible before sowing, Heptachlor 1.250 l/ha should be applied drop by drop with irrigation water or other-wise Endosulphan 0.8 kg a.i./ha + 5 liters of water + 100 kg sand should be mixed thoroughly and broadcasted in the standing crop but irrigation must be applied earlier or should be applied lightly after its application.
