What is a happy seeder versus a super seeder, and which suits my farm after paddy?

Both let you sow wheat into paddy residue without burning, but they handle the straw differently. A happy seeder cuts and lifts the standing stubble and drills wheat in one pass, leaving the loose straw on the surface as mulch. A super seeder cuts and partly incorporates the straw into the soil while sowing, giving a cleaner field and good seed to soil contact, but it usually needs more tractor HP and more fuel. The super seeder suits farmers who prefer the residue mixed in and have a higher HP tractor, while the happy seeder is lighter on power and keeps straw as surface mulch that conserves moisture. Both need a tractor strong enough for heavy stubble. Hire and try the one suited to your tractor and soil before buying. State residue management schemes give subsidy on both, so check current rates with your agriculture office.
