READ MORE >>Wet seedingDry seedingWater seedingSeed rate is an important factor to consider in direct sowing. Seed Rate Potential yeild of a healthy crop is usually about 350-400 panicles/sq. m.Seed rate should be adjusted accordingly.medium grain size (23-25 g/1000 seeds) – about 100 kg/ha.small grain size (“Samba”) – about 75-80 kg/ha.In general, required seed rate decreases with increasing seed weight.Varieties available for planting – READ MORE>>Seed rate will also be a critical factor when dry seeding is practiced, as seeds may get damaged due to various reasons. Imperferct Seed Rates and Density Will have a negative impact on crop.Within the same seed size classdecreasing seed rates would increase unproductive tillering.increasing seed rates would reduce yeild due toincrease in plant density.lead to unhealthy seedlings with small panicles.increase in susceptibility to pest and diseasesA uniform plant density can be maintained byuprooting seedlings from high plant density areas (thinning out).transplanting seedlings in places having low plant density.
