You can adopt any method that suits to you but seeds should be buried atleast 1/2inch to 1inch under the soil. Soaking is not at all needed.
The differences told to by individuals may be based on their soil conditions. when tilled if soil becomes lumps, farmers adopt rotovating so ploughing method has nothing to do with sunhemp seeds.
Thanks for the clarification. Sorry for the newbie question. But how are the seeds broadcasted so that they are buried 1 inch under the soil?
Is it done through tractor ploughs or is there any other equipment?
you can follow as said by Sri sir, comfortably. As said by him, Soaking is not required for sunhemp seeds germination.
As you asked, in detail, I will give my experience of sunhemp crop. first ploughed my land with tractor single plough. Spread required FYM and followed twice with cultivator ploughing, and finally with Rotovator. Spread seeds of Sunhemp seeds along with utcellu,(yerri nugulu ), Pilli pesara, Horse gram ( ulavalu ), and applied local wooden posts with Ox plough. Immediately used the sprinklers for watering, and continued daily.
It will take approximately 40 to 45 days to get flowering. After a flowering of 10 to 15% in the sunhemp plants, they are ready for ploughing in the soil. Then we cut the plants and after cutting we have spread, Bone meal and other required mannures for my coming crop and we ploughed it with cultivator twice , followed by Rotovator. As you asked, it will take hardly 45 days for the entire process.
Further, it may not be out of place to mention here to add Utchellu , Pilli pesara (wild Heara bedalu), Ulavalu ( horse gram ) etc , along with sunhemp seeds, sowing also is very good.
This will provide sufficient green mannure for our soil and enriches. Along with animal mannure and other mannures, green mannure is also equally important, and it plays a vital role.
