WET NURSERY Nursery area: Select 20 cents (800 m 2 ) of land area near to water source for raising seedlings for one hectare. Seed rate: 30 kg for long duration; 40 kg for medium duration; 60 kg for short duration varieties and 20 kg for hybrids. Seed treatment Treat the seeds with Carbendazim or Pyroquilon or Tricyclozole solution @ 2 g/l of water for 1 kg of seeds. This wet seed treatment gives protection to the seedlings up to 40 days from disease such as blast and this method is better than dry seed treatment. If the seeds are required for sowing immediately, keep the soaked seed in gunny in dark and cover with extra gunnies and leave for 24hrs for sprouting. Seed treatment with Pseudomonas fluorescens : Treat the seeds with talc based formulation of Pseudomonas fluorescens 10g/kg of seed and soak in 1.0 lit of water overnight. Decant the excess water and allow the seeds to sprout for 24hrs and then sow. Seed treatment with Azospirillum : Treat with three packets (600 g/ha) of Azospirillum and 3 packets (600g/ha) of Phosphobacteria or 6 packets (1200g/ha) of Azophos . In bio- inoculants mixed with sufficient water wherein the seeds are soaked overnight before sowing in the nursery bed (The bacterial suspension after decanting may be poured over the nursery area itself).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
