| Special Technology - 4 |
| Name of the crop |
: |
Castor |
Name of the management practice/Production/
Protectiontechnology of TNAU |
: |
Castor cultivation with Onion intercropping |
| Recommendation /advice for adoption |
: |
Castor cultivation with Onion intercropping.In this intercropping system (Castor –Onion in 1:2 ratio.i.e.one row of castor +two rows of onion by adopting the spacing of 1.5m*1.0m for hybrid castor crop and adopting 60*30*60 cm Spacing i.e. leaving 60 cm either side of the castor crop by providing 30 cm spacing for onion crop.this system will be raised to getadditional productivity & profitability.
|
| Benefits expected due to adoption of this technology |
: |
Suppress the weed growth at initial castor crop establishment stage there by harboring of pest and disease pathogens due to weed plants will be controlled .this will indirectly reduce the usage of herbicided and plant protection chemicals, creates safety environment.Besides one weeding cost will be reduced and farmers will get the high netreturns by rasing castor with onion intercropping.
