1. Seed production, processing and storage techniques for agricultural, horticultural, forage and silvicultural crops.
2. Paddy seed upgradation using common salt solution (2 kg NaCl in 10 lit. of  water)  to remove floaters based on density.
3. Acid method of seed extraction in brinjal and tomato : Soaking fruit pulp in HCl @ 25 ml / kg for 30 min. with frequent stirring,  washing thoroughly with water and collection of settled seeds.
4. Delinting of cotton seeds with commercial sulphuric acid @ 100 ml / kg for
   2-3 min. followed by thorough washing and drying.
5. Tendril clipping in cowpea at alternate days to reduce vegetative growth and to induce flowering and pod set.
6. Storing groundnut pods in gunny bags with CaCl₂ @ 250 g /30 kg of pods inside the plastic container extends the storability of pods.
7. Pre harvest sanitation spray with malathion 50 EC @ 0.05 % 3 – 5 days prior to harvest to control pulse beetle.
8. Keeping  bee hives @ 5 No./ ha for improving the seed set in sunflower.
9. Foliar spray of NAA 20ppm for vegetables and 40 ppm for cotton to reduce flower drop.
10. Seed pelleting with pelleting mixture or leaf powder @100 -200 g / kg of seeds to increase the size and shape of the seed suitable for mechanized sowing in all crops.
11. Seed coating with polymer @ 3 g dissolved in 5 ml of water / kg of seeds to enhance the field emergence in maize, pulses, cotton and vegetables.
12. Foliar spray with 2% DAP at the time of flower initiation and 15 days after first spray to improve seed set and seed size in all pulses.
13. Seed treatment with halogen mixture @ 3 g / kg of seed (CaOCl₂ + CaCO₃ + Arappu leaf powder @ 5:4:1 ratio) as a pre storage treatment.
14. Live seed separation in groundnut – soaking groundnut seeds in 0.5% CaCl₂ for 6 hours and incubation in moist gunnies for overnight and collection of  pre- germinated seeds for sowing.
15. Seed hardening to withstand drought condition :

 

• Soaking paddy seeds in equal volume of KCl 1%  solution for 16 hours
• Soaking red gram and black gram seeds in 1/3^rd volume of ZnSO₄
  100 ppm solution for 3 hours
• Soaking green gram seeds in 1/3^rd volume of MnSO₄ 100ppm solution for 3 hours
• Soaking sorghum seeds in  600ml of KH₂PO₄ 2 % solution for 10 hours
• Soaking maize seeds in  equal volume of KH₂PO₄ 2 % solution for 8 hours
• Soaking pearl millet seeds in 650ml of KCl 2 % solution for 10 hours

• Soaking cotton seeds in equal volume of KCl  2 %  solution for 3 hours
• Soaking sunflower seeds in equal volume of KNO₃ 2 % solution for 6 hours
• Soaking ragi seeds in equal volume of CaCl₂ 0.5 % solution for 12 hours

 

1. Seed treatment with Carbendazim or bavistin @ 2 g / kg of seeds before storage – All crops.
2. Seed dormancy breaking and seed testing methods for popular tree species.
3. Seed testing methods for medicinal crops.
